摘要
为确定电化学与纳米晶磁组合技术应用于重金属废水处理的最佳设计参数,采用中试实验研究了电化学与纳米晶磁组合技术在重金属废水处理上的应用效果,并研究了不同分子量絮凝剂(聚丙烯酰胺,即PAM)、不同表面水力负荷对纳米晶磁技术处理效果的影响。结果表明:电化学与纳米晶磁组合技术应用于重金属废水处理,1600万分子量的絮凝剂(PAM)与纳米晶磁磁种具有更好的磁混凝协同效果,固液分离区最佳表面水力负荷为15m^3/m^2·h,且处理过程中完全不用投加混凝剂(PAC)。
In order to determine the most effective design parameters of electrochemistry and nanocrystalline magnetic combination technology for heavy metal wastewater treatment.In this paper,the effect of the combination of electrochemistry and nanocrystalline magnetic technology on the treatment of heavy metal wastewater was studied by pilot test,and the effect of different molecular weight flocculants(polyacrylamide,namely PAM)and different surface hydraulic load on the treatment effect of nanocrystalline magnetic technology was studied.The results show that when the combination technology of electrochemistry and nanocrystalline magnetism is applied to the treatment of heavy metal wastewater,the 12 million molecular weight flocculant(PAM)and nanocrystalline magnetism seed have better synergistic effect of magnetic coagulation,The most effective surface hydraulic load in the solid-liquid separation area is 15 m^3/m^2.h,and the coagulant(PAC)is not used in the treatment process.
