【摘要】 采用电腐蚀 -中和反应 -内电解 -混凝沉淀 -厌氧 -好氧组合工艺 ,对某企业排放的高浓度酸性生产废水进行了中试研究。研究结果表明 ,废水经本工艺处理后 ,COD、BOD的总去除率达到 99%以上 ,出水pH7～ 8,符合国家《污水综合排放标准》(8978- 1 996)中二级排放标准的要求。更多还原

【Abstract】 High Concentration acidic wastewater is treated by neutralization reaction,interior electrolytic,coagulation,anaerobic and aerobic processes.The resuts show that after the treatment 99% COD and BOD has been removed from the wastewater and the water pH is 7-8,measuring up to the second grade standard of (8978-1996).更多还原
