有色冶金废水浓度高、污染物复杂,排放前必须经过有效处理.生物反应器是常用的有色冶金废水处理设备,但是有关不同反应器的研究进展缺乏总结、比较.通过文献计量分析指出了生物反应器研究概况,并明确生物反应器属于未来的热点技术之一.此外,对 3 种具有代表性的生物反应器膜生物反应器(Membrane bioreactor,MBR)、移动床生物膜反应器(Moving bed biofilm reactor,MBBR)、生物滤池(Biological filter,BF)进行系统性综述和比较,提出了各自的适用场景、强化措施和未来研究方向.本文系统总结了MBR、MBBR和BF的特点,为有色冶金废水实际处理中装置选择提供了参考依据.
Application of bioreactor in nonferrous metallurgical wastewater treatment
Non-ferrous metallurgical wastewater has high concentrations and complex pollutants,which must be effectively treated before discharge.The bioreactor is a commonly used non-ferrous metallurgical wastewater treatment equipment,but the research progress of different reactors lacks a summary and comparison.This review of bioreactors is pointed out by bibliometric analysis,and it is ascertained that bioreactor is one of the hot technologies in the future.In addition,the three representative bioreactors membrane bioreactor(MBR),moving bed biofilm reactor(MBBR)and biological filter(BF)are systematically reviewed and compared,and their respective applicable scenarios,strengthening measures and future research directions are proposed.This study systematically summarizes the research characteristics of MBBR,MBR and BF,and provides a reference for selecting devices to treat non-ferrous metallurgical wastewater.
