    Cr-containing wastewater treatment based on Cr self-catalysis:a critical review

    Manshu ZhaoXinhua WangShuguang WangMingming Gao...
    1-22页
    查看更多>>摘要：Chromium(Cr),as a transition metal material with multiple redox states,has exhibited the catalysis toward Fenton-like reactions over a wide pH range.Although it is not sensible to add Cr reagents as catalysts due to its toxicity,it is highly promising to remediate Cr-containing wastewater through Cr-initiated advanced oxidation processes(Cr-initiated AOPs),which are clean and low-cost.Moreover,the widely concerned Cr-complexes,considered as obstacles in the remediation process,can be effectively destroyed by AOPs.Cr self-catalysis is defined as Cr species is both substrate and catalyst.However,the full understanding of Cr self-catalysis,including the generation of intermediates Cr(Ⅳ)/Cr(Ⅴ),the synergetic effects with co-existing ions,and the accumulation of toxic Cr(Ⅵ),remains a challenge for the practical application of Cr-initiated AOPs.In this review,relevant researches on Cr self-catalysis during Cr-initiated AOPs are summarized.Specifically,the Cr-Fenton-like reaction,Cr substituted materials,and Cr-sulfite reactions are explored as key mechanisms contributing to Cr self-catalysis.Moreover,Cr transformation processes,including synchronously Cr removal,Cr redox reactions,and Cr(Ⅵ)accumulation,in AOPs-based synergistic systems are systematically analyzed.Detailed approaches for the detection of active species in AOPs-based systems are also presented.The primary objective of this review is to explore the application of AOPs for Cr-containing wastewater remediation based on Cr self-catalysis,and provide fundamental insights and valuable information for future research on Cr-initiated AOPs.

    Synergistic promotion of particulate matter reduction and production performance via adjusting electrochemical reactions in the zinc electrolysis industry

    Zizhen MaJingkun JiangLei DuanJianguo Deng...
    23-33页
    查看更多>>摘要：Heavy particulate matter(PM)pollution and high energy consumption are the bottlenecks of hydrometallurgy,especially in the electrolysis process.Therefore,an urgent need is to explore PM reduction methods with production performance co-benefits.This study presents three PM reduction methods based on controlling operating parameters,i.e.,lowering electrolyte temperature,H2SO4 concentration,and current density of the cathode.The optimized conditions were also investigated using the response surface methodology to balance the PM reduction effect and Zn production.The results showed that lowering electrolyte temperature is the most efficient,with an 89.0％reduction in the PM generation flux(GFPM).Reducing H2SO4 concentration led to the minimum side effects on the current efficiency of Zn deposition(CEZn)or power consumption(PC).With the premise of non-deteriorating CEZn and PC,GFPM can be reduced by 86.3％at the optimal condition(electrolyte temperature=295 K,H2SO4=110 g/L,current density=373 A/m2).In addition,the reduction mechanism was elucidated by comprehensively analyzing bubble characteristics,electrochemical reactions,and surface tension.Results showed that lower electrolyte temperature inhibited the oxygen evolution reaction(OER)and compressed gas volume.Lower H2SO4 concentration inhibited the hydrogen evolution reaction(HER)and reduced electrolyte surface tension.Lower current density inhibited both OER and HER by decreasing the reaction current.The inhibited gas evolutions reduced the microbubbles'number and size,thereby reducing GFPM.These results may provide energy-efficient PM reduction methods and theoretical hints of exploring cleaner PM reduction approaches for industrial electrolysis.

    Conductive and stable polyphenylene/CNT composite membrane for electrically enhanced membrane fouling mitigation

    Huijuan XieHaiguang ZhangXu WangGaoliang Wei...
    35-47页
    查看更多>>摘要：Nanocarbon-based conductive membranes,especially carbon nanotube(CNT)-based membranes,have tremendous potential for wastewater treatment and water purification because of their excellent water permeability and selectivity,as well as their electrochemically enhanced performance(e.g.,improved antifouling ability).However,it remains challenging to prepare CNT membranes with high structural stability and high electrical conductivity.In this study,a highly electroconductive and structurally stable polyphenylene/CNT(PP/CNT)composite membrane was prepared by electropolymerizing biphenyl on a CNT hollow fiber membrane.The PP/CNT membrane showed 3.4 and 5.0 times higher electrical conductivity than pure CNT and poly(vinyl alcohol)/CNT(PVA/CNT)membranes,respectively.The structural stability of the membrane was superior to that of the pure CNT membrane and comparable to that of the PVA/CNT membrane.The membrane fouling was significantly alleviated under an electrical assistance of-2.0 V,with a flux loss of only 11.7％after 5 h filtration of humic acid,which is significantly lower than those of PP/CNT membranes without electro-assistance(56.8％)and commercial polyvinylidene fluoride(PVDF)membranes(64.1％).Additionally,the rejection of negatively charged pollutants(humic acid and sodium alginate)was improved by the enhanced electrostatic repulsion.After four consecutive filtration-cleaning cycle tests,the flux recovery rate after backwashing reached 97.2％,which was much higher than those of electricity-free PP/CNT membranes(67.0％)and commercial PVDF membranes(61.1％).This study offers insights into the preparation of stable conductive membranes for membrane fouling control in potential water treatment applications.

    Microbial-driven ectopic uranium extraction with net electrical energy production

    Xin TangYin YeChunlin WangBingqian Wang...
    49-58页
    查看更多>>摘要：The extraction of uranium(U)from U-bearing wastewater is of paramount importance for mitigating negative environmental impacts and recovering U resources.Microbial reduction of soluble hexavalent uranium(U(Ⅵ))to insoluble tetravalent uranium(U(Ⅳ))holds immense potential for this purpose,but its practical application has been impeded by the challenges associated with managing U-bacterial mixtures and the biotoxicity of U.To address these challenges,we present a novel spontaneous microbial electrochemical(SMEC)method that spatially decoupled the microbial oxidation reaction and the U(Ⅵ)reduction reaction.Our results demonstrated stable and efficient U extraction with net electrical energy production,which was achieved with both synthetic and real wastewater.U(Ⅵ)removal occurred via diffusion-controlled U(Ⅵ)-to-U(Ⅳ)reduction-precipitation at the cathode,and the UⅣO2 deposited on the surface of the cathode contributed to the stability and durability of the abiotic U(Ⅵ)reduction.Metagenomic sequencing revealed the formation of efficient electroactive communities on the anodic biofilm and enrichment of the key functional genes and metabolic pathways involved in electron transfer,energy metabolism,the TCA cycle,and acetate metabolism,which indicated the ectopic reduction of U(Ⅵ)at the cathode.Our study represents a significant advancement in the cost-effective recovery of U from U(Ⅵ)-bearing wastewater and may open a new avenue for sustainable uranium extraction.

    Comparative analysis of DNA-SIP and magnetic-nanoparticle mediated isolation(MMI)on unraveling dimethoate degraders

    Luning LianYi XingDayi ZhangLongfei Jiang...
    59-69页
    查看更多>>摘要：Microorganisms are crucial in the bioremediation of organophosphorus pesticides.However,most functional microorganisms(＞99％)are yet to be cultivated.This study applied two cultivation-independent approaches,DNA-SIP and magnetic-nanoparticle mediated isolation(MMI),to identify the functional microorganisms in degrading dimethoate in agricultural soils.MMI identified five dimethoate degraders:Pseudomonas,Bacillus,Ramlibacter,Arthrobacter,and Rhodococcus,whereas DNA-SIP identified three dimethoate degraders:Ramlibacter,Arthrobacter,and Rhodococcus.Also,MMI showed higher resolution than DNA-SIP in identifying functional microorganisms.Two organic phosphohydrolase(OPH)genes:ophC2 and ophB,were involved in dimethoate metabolism,as revealed by DNA-SIP and MMI.The degradation products of dimethoate include omethoate,O,O,S-trimethyl thiophosphorothioate,N-methyl-2-sulfanylacetamide,O,O-diethyl S-hydrogen phosphorodithioate,O,O,O-trimethyl thiophosphate,O,O,S-trimethyl thiophosphorodithioate,and O,O,O-trimethyl phosphoric.This study emphasizes the feasibility of using SIP and MMI to explore the functional dimethoate degraders,expanding our knowledge of microbial resources with cultivation-independent approaches.

    Characterization and prediction of tailpipe ammonia emissions from in-use China 5/6 light-duty gasoline vehicles

    Lewei ZengFengbin WangShupei XiaoXuan Zheng...
    71-81页
    查看更多>>摘要：On-road tailpipe ammonia(NH3)emissions contribute to urban secondary organic aerosol formation and have direct or indirect adverse impacts on the environment and human health.To understand the tailpipe NH3 emission characteristics,we performed comprehensive chassis dynamometer measurements of NH3 emission from two China 5 and two China 6 light-duty gasoline vehicles(LDGVs)equipped with three-way catalytic converters(TWCs).The results showed that the distance-based emission factors(EFs)were 12.72±2.68 and 3.18±1.37 mg/km for China 5 and China 6 LDGVs,respectively.Upgrades in emission standards were associated with a reduction in tailpipe NH3 emission.In addition,high NH3 EFs were observed during the engine warm-up period in cold-start cases owing to the intensive emissions of incomplete combustion products and suitable catalytic temperature in the TWCs.Notably,based on the instantaneous NH3 emission rate,distinct NH3-emitting events were detected under high/extra high velocity or rapid acceleration.Furthermore,NH3 emission rates correlated well with engine speed,vehicle specific power,and modified combustion efficiency,which were more easily accessible.These strong correlations were applied to reproduce NH3 emissions from China 5/6 LDGVs.The predicted NH3 EFs under different dynamometer and real-world cycles agreed well with existing measurement and prediction results,revealing that the NH3 EFs of LDGVs in urban routes were within 8.55-11.62 mg/km.The results presented here substantially contribute to improving the NH3 emission inventory for LDGVs and predicting on-road NH3 emissions in China.

    Direct generation of Zn metal using laser-induced ZnS to eradicate carbon emissions from electrolysis Zn production

    Ying ChenNing DuanLinhua JiangFuyuan Xu...
    83-95页
    查看更多>>摘要：In response to the goal of net-zero emissions proposed by Intergovernmental Panel on Climate Change,Chinese government has pledged that carbon emissions will peak by 2030,and achieve carbon neutrality by 2060.However,the high carbon energy structure of traditional industries has aggravated environmental problems,such as greenhouse effect and air pollution.The goal of carbon neutrality will be difficult to achieve without the development of disruptive theories and technologies.The electrolytic zinc industry requires high-temperature roasting at～1000 ℃,generating large amounts of greenhouse gases and SO2.High concentrations of sulfuric acid(200 g/L)are subsequently used for electrolysis,and each ton of zinc produced generates 50 kg of anode slime with lead content of up to 16％,as well as 0.35 m3 of wastewater containing zinc and lead.To solve these problems,an optical metallurgy method is proposed in this study.The proposed method uses laser-induced photoreduction to decompose ZnS and reduce metal ions to metal.Results indicate that Zn0 and S8 can be detected on the surface of ZnS at a specific wavelength and laser fluence.The generation mechanism of Zn0 is such that laser induces an electronic transition that breaks ionic bond in ZnS,resulting in its decomposition and photoreduction to Zn0 under an inert argon gas atmosphere.This method does not reduce other metals in the mineral since it does not use high-temperature roasting,providing a new way of producing high-purity metal without greenhouse gas emissions and heavy metal pollution caused by traditional zinc electrolysis.

    A novel deep learning framework with variational auto-encoder for indoor air quality prediction

    Qiyue WuYun GengXinyuan WangDongsheng Wang...
    97-109页
    查看更多>>摘要：Exposure to poor indoor air conditions poses significant risks to human health,increasing morbidity and mortality rates.Soft measurement modeling is suitable for stable and accurate monitoring of air pollutants and improving air quality.Based on partial least squares(PLS),we propose an indoor air quality prediction model that utilizes variational auto-encoder regression(VAER)algorithm.To reduce the negative effects of noise,latent variables in the original data are extracted by PLS in the first step.Then,the extracted variables are used as inputs to VAER,which improve the accuracy and robustness of the model.Through comparative analysis with traditional methods,we demonstrate the superior performance of our PLS-VAER model,which exhibits improved prediction performance and stability.The root mean square error(RMSE)of PLS-VAER is reduced by 14.71％,26.47％,and 12.50％compared to single VAER,PLS-SVR,and PLS-ANN,respectively.Additionally,the coefficient of determination(R2)of PLS-VAER improves by 13.70％,30.09％,and 11.25％compared to single VAER,PLS-SVR,and PLS-ANN,respectively.This research offers an innovative and environmentally-friendly approach to monitor and improve indoor air quality.

    查看更多>>摘要：This study developed a novel MnFe-LDH/PMS/O3 three-phase catalytic system to degrade the organic dye RhB,which was used to address the drawbacks of persulfate oxidation and ozonation techniques.The structure,ionic and elemental composition,specific surface area,and magnetic properties of the LDHs were investigated using a variety of physicochemical characterization tools.The results showed that MnFe-LDH had a large specific surface area,a rich crystalline phase composition,and a functional group structure.The RhB degradation rate of MnFe-LDH/PMS/O3 was 0.34 min-1,which was much higher than that of other comparative systems.RhB could be completely degraded in 10 min after optimization and had a significant effect on TOC removal.The system was found to be effective over a wide pH range.Common anions were largely unaffected and humic acid acted as an inhibitor.At the same time,the system had generally effective degradation performance for different dyes.Combined with quenching experiments and EPR,it was found that SO4·-,·OH,O2·-,and 1O2 all participated in the reaction,and·OH contributed more.The degradation pathway of RhB was derived by LC-MS,and the T.E.S.T.evaluation found that the toxicity of the intermediate product was significantly reduced.Finally,the stability and availability of LDHs were verified using cycling experiments and metal ion leaching.This work provides a theoretical basis and data support for the synergistic catalysis of PMS/O3 and the deep treatment of dye wastewater.

    129-144页
    查看更多>>摘要：Light emitting diode(LED-UV)/chlorine disinfection can replace UV/chlorine disinfection in wastewater treatment plants and water supply plants.Halonitromethanes(HNMs)are a class of novel nitrogenous disinfection by-products,which are characterized by higher cytotoxicity and genotoxicity than regulated disinfection by-products.Herein,the impact factors and pathways of HNMs formation from aspartic acid(ASP)were investigated during LED-UV265/chlorine disinfection.The results showed that three types of chlorinated-HNMs(Cl-HNMs)were found during LED-UV265/chlorine disinfection,and their concentrations increased first and then declined as the reaction progressed.Cl-HNMs yields increased with increasing LED-UV265 intensity,free chlorine dosage,and ASP concentration,which declined with increasing pH(6.0-8.0).Meantime,the important impact of the coexisting ions contained in water matrices on HNMs formation from ASP was observed during LED-UV265/chlorine disinfection.It was found that copper ions(Cu2+)promoted Cl-HNMs formation.Furthermore,when bromide(Br)appeared during LED-UV265/chlorine disinfection,nine types of HNMs were detected simultaneously.Moreover,Br not only converted Cl-HNMs toward brominated(chlorinated)-HNMs and brominated-HNMs but also showed a marked effect on HNMs concentrations and species.Subsequently,the possible pathways of HNMs formation from ASP were proposed during LED-UV265/chlorine disinfection.At last,it was proved that the formation trends of HNMs obtained in the real waters were similar to those in simulated waters.This work elaborated on the influence factors and pathways of HNMs formation,which is conducive to controlling the HNMs produced during LED-UV265/chlorine disinfection.
