摘　　要：采用新型微电解 -生物膜法处理含重金属离子有机废水 ,同时 ,与单纯的微电解工艺、生物膜工艺进行了对比 ,Cr3 + 离子去除率均提高 15 %。在实验过程中 ,废水中的有机物 ,由生物膜中的复合微生物菌群作为营养源而消耗 ;重金属离子 (Cr3 + )则通过电沉积去除一部分 ,同时生物膜吸附另一部分而去除 。In this article,a novel complex process of electro-deposition and biofilm is utilized to treat organic wastewater containing heavy metal ion (Cr 3+ ) which is seriously harmful to human beings environment. Meanwhile, compared with single electro-deposition or biofilm process,the removal rate of Cr 3+ ion will be increased by 15%.Organic materials in wastewater are consumed as nutritious source of biofilm.However, for heavy metal ion (Cr 3+ ), one part is removed by electro-deposition, the other part is absorbed on biofilm, and the purified water can surpass the standard of industrial reused water.
