摘要
针对中晚年垃圾填埋场渗滤液高浓度氨氮影响生化系统运行,研究采用灵活增设磷酸铵镁化学沉淀法达到降低氨氮浓度。试验考察了沉淀时间、pH、药剂投加配比等因素对中晚期垃圾渗滤液中氨氮去除的影响。在最佳条件下,氨氮的去除率为95%,为后续的生化单元提供了保障。
The old landfill leachate have high ammonia nitrogen.To remove efficiently bio-system operation,the magnesium ammonium phosphate（MAP） precipitation process was used to treat the landfill leachate,and the effects of sediment time,pH and ratio of chemical agent on the ammonia nitrogen removal were investigated.In best condition,the ammonia nitrogen removal rate reaches 95 %,for the follow-up of the bio-system unit provides security.
