内电解-厌氧-好氧工艺处理垃圾渗沥液的研究

Experimental studies on the treatment of leachate by interior electrolytic, anaerobic and aerobic processes

研究了高COD和高氨氮的生活垃圾渗沥液 ,在内电解 -厌氧 -好氧组合工艺下的处理效果及其影响因素。结果表明 ,内电解 -厌氧 -好氧组合工艺 ,应用在高COD、高氨氮 (COD为 10 0 0 0～ 90 0 0 0mg L ,氨氮 >6 0 0mg L)生活垃圾渗沥液处理中 ,具有较高的COD和色度去除率。在全工艺流程下 ,COD的去除率达到 99%以上 ,氨氮去除率达到 90 %以上。

The efficiencies and influential factors of the treatment of leachate with high concentration and ammonia-nitrogen are studied by interior electrolytic and aerobic processes.Test results show that when interior electrolytic,anaerobic and aerobic processes are used in the treatment of leachate with high concentration and ammonia-nitrogen(COD Cr 10 000～90 000 mg/L and ammonia-nitrogen>600 mg/L),the COD removal rate is up to 99%,and the ammonia-nitrogen removal rate is up to 90%.
