摘　　要：通过静态试验,研究了生化-铁碳微电解-生化、生化-铁碳微电解-混凝沉淀、混凝沉淀-铁碳微电解-生化3种工艺降解造纸废水COD的效果,考察了铁碳微电解法对造纸废水生化性能的改善。试验结果表明,经过铁碳微电解预处理后的造纸废水,其生化性能得以增强;相对混凝沉淀出水,铁碳微电解出水采用生化处理作为后续处理工艺更佳,其COD去除效果更好。This study is based on static test of pulp and paper making wastewater COD decrease of biochemical - ferric - carbon micro - electrolysis - biochemical, biochemical - ferric - carbon micro - electrolysis - coagulation and coagulation - ferric - carbon micro - electrolysis - biochemical processes. The influence of ferric - carbon micro - electrolytic pretreatment performance on biodegradation was studied. Test results show that biodegradation can be improved after ferric - carbon micro - electrolysis pre- treatment. Comparing with coagulate settling pretreatment, ferric - carbon micro - electrolysis pretreatraent is better for next biochemical treatment, and with high COD remove rate as well.
