    Diurnal variations of water-soluble ions in PM2.5 in Shanghai

    查看更多>>摘要：Thirty-six daily time interval PM205 samples were collected in different seasonal dates in urban Shanghai, and the concentrations of four anions (Cl-, NO3-, SO42-, C2O42-) and five cations (NH4+, Na+, K+, Ca2+, Mg2+) were analyzed with ion chromatography. Sulfate, nitrate and ammonium were found to be the dominant species, accounting for about 80% of the total ions. The daily nitrate to sulfate mass ratio ranged from 0.31 to 0.82, indicating that coal combustion was still the main pollution source in Shanghai. The equivalent ratio of ammonium to sum of nitrate and sulfate showed fixed diurnal variation pattern in all the sampling days with higher values in the nighttime, suggesting that fine particles in the night were more neutralized. The oxalate to sulfate ratio was lower in the winter sampling days than that in hotter summer and autumn sampling days. Oxalate was significantly correlated with sulfate in winter sampling days, but not in the summer and autumn, suggesting that the formation mechanism of oxalate and sulfate was similar in winter, however different in hot days.

    Noise-induced cooperative dynamics and its control in coupled electrochemical models

    PI Zong-xinGUO Hui-jiaoGUO Jing-xinGENG Hong-ya...
    241-245页
    查看更多>>摘要：We have investigated the feedback control of the cooperative dynamics of two coupled electrochemical oscillators that is induced merely by external noise. The interacting electrochemical ceils are modeled with parameter values at which no autonomous oscillations occur, and each unit is forced by its own source of random fluctuations. Application of delayed feedback to only one of two subsystems is shown to be able to change the coherence and time scales of noise-induced oscillations either in the given subsystem or globally. It can also induce or suppress stochastic resonance under the certain conditions.

    Novel FGBAC reactor for controlling the leakage of microfauna in drinking water treatment

    246-250页
    查看更多>>摘要：In order to reduce the microfauna leakage risk from a granular biological activated carbon (GBAC) reactor which employs granular activated carbon (GAC) as adsorption media in drinking water advanced treatment, a novel fiber and granular biological activated carbon (FGBAC) reactor which employs both GAC and activated carbon fiber (ACF) as adsorption media, was developed. The results showed that the species composition of microfauna leaking from FGBAC reactor is almost similar to that leaking from GBAC reactor, however the densities of microfauna leaking from FGBAC reactor is reduced by 26%-81% compared to those leaking from GBAC reactor. In addition, compared to GBAC reactor, FGBAC reactor can increase the removal efficiencies of chemical oxygen demand (COD) and turbidity by 7% and 10%, respectively, during the stable operation period of reactor.

    Effects of operative conditions on membrane fouling of jet loop membrane bioreactor

    251-254页
    查看更多>>摘要：The orthogonal experiments, which involves three factors: aeration intensity, suction time and suction suspended time, were designed to research membrane fouling of jet loop membrane bioreactor (JLMBR). Experimental results indicate that increasing aeration intensity, reducing suction time and increasing suction suspended time all could mitigate membrane fouling effectively. However excessive aeration intensity, too short suction time and excessive suction suspended time were bad for bioreactor running. The optimal aeration intensity, suction time and suction suspended time were 0.75-1.00 m3/(m2.h),8-10 min and 4-5 min, respectively. The three factors all had effect on membrane pollution rate, while the suction time was the most important one and followed by aeration intensity and suction suspended time. It also indicates that, comparing with traditional submerged membrane bioreactors, JLMBR had lower membrane pollution rate.

    Temperature dependence of microscopic properties in diblock copolymer films: A dissipative particle dynamics simulation

    XU YiFENG JianSONG Xiao-yuWANG Yong...
    255-261页
    查看更多>>摘要：Temperature dependence of microscopic properties in diblock copolymer films has been investigated by dissipative particle dynamics simulations.Results show the relation between mean-square bond length (MSBL) and system temperature can be described as a quadratic curve.The root-mean-square radius of gyration (RMSGR) and end-end distance (RMSED)increase gradually as the temperature rises and composition fraction changes from 0.1 to 0.5,in which the effect of the former is primary.Especially,the relation between RMSGR and temperature is nearly linear in the confinement-introduced direction.Density distribution of each component in the films can be controlled and adjusted effectively by its interaction with other components and boundaries.Moreover,the changes of system temperature and composition fraction can both affect the density distributions to a certain extent.

    查看更多>>摘要：Daqing Wetland was contaminated by heavy metals for holding lots of industrial and domestic waste water.Due to their high stability and non-degradation,heavy metals are possible to gather in human body through the food chain and then threaten health.Water samples were collected from Longfeng Wetland and lake marshes in the vicinity of Daqing City.The contents of heavy metals (Cd,Pb,Cr,Cu,Zn,Ni) were determined,and the contamination degrees were evaluated simultaneously.The results indicate that heavy metals of Zn,Ni,Cd,Cr and Pd have contaminated the Longfeng Wetland severely.In addition the concentrations of Cr and Cd in some lakes around oil wells are excessively high,and have overrun the grade V based on the threshold values of surface water given by the National Environmental Protection Agency of China.Some measures have to be taken to tackle heavy metal contamination of Longfeng Wetland and lake marshes in Daqing City.

    Hydrodynamics and oxygen transfer in a novel extra-loop fluidized bed bioreactor

    266-274页
    查看更多>>摘要：In this paper,the characteristics of fluid mixing time in a novel extra-loop fluidized bed were studied.The results showed that the mixing time was shortened with the increase of fluid velocity.All the discrete numbers of the reactor were above 0.2.The serial number n was 2.5-3.0.It was judged accordingly that the reactor fluid state was continous stirred tank reactor (CSTR) mainly.When the inspiratory capacity increased the mixing time of the reactor was shortened.Thus the air input was beneficial for the fluid mixing.During the three phases mixing process,the mixing time of the reactor could be decreased by the n increase of carrier and air loading together,but the change was not significant.The parameters affecting the reactor fluid state were fluid velocity,inspiratory capacity and carrier,KLa could be increased with the air loading increase,and at the same gas/liquid ratio when the pressure drop was high,KLa value was increased.The amount of carrier complex influence on KLa.As the carrier loading continued to increase,its value had been dropped but the changes was not significant,and optimization condition was found at above 800-1000 g carrier loading (pouzzolane) or 600 g PVC.Under gas/liquid ratio of 0.8%-5.2%,KLa was (0.62-1.37)×10-2 s-1.

    Decomposition mechanism of chloramphenicol under electron beam irradiation

    ZHOU Jia-xinWU Ming-hongXU GangREN Lai-tang...
    286-291页
    查看更多>>摘要：The purpose of this study was to evaluate the potential of electron beam to decompose chloramphenicol(CAP)in aqueous solutions.At the absorbed dose of 15 kGy,the decomposition rate of CAP was 95.24%.The degradation of CAP under electron beam irradiation followed pseudo-first-order kinetics.Redox reactions of CAP aqueous solutions with hydroxyl radicals(·OH),hydrated electrons(e-aq)and hydrated atoms(·H)were studied.The increase of the additives would result in the decrease of the degradation efficiency.The concentration of Cl-and NO3-in aqueous solution increased after electron beam irradiation.On the basis of the experimental results,a photocatalytic mechanism was discussed.The rate constant for reactions of ·OH and CAP was 9.36×107 L/(mol·s)and for reaction of e-aq and CAP was 7.33×107 L/(mol·s).·OH was supposed to play the key role in the radiation system of aqueous solution.Other free radicals like e-aq and ·H could also initiate the degradation.
