摘要
介绍了同时硝化 反硝化 (SND)生物脱氮技术在江苏省吴江市垃圾卫生填埋场渗滤液处理中的实验和应用情况。研究结果表明 :同时好氧硝化 反硝化技术可以实现硝化耗碱和反硝化产碱互补 ,使得反应pH控制变得简单经济 ;在第一曝气池中的溶解氧浓度在 1～ 2mg L、第二曝气池中溶解氧浓度维持在 3～ 4mg L时 ,出水氨氮浓度可以保持在 <5mg L的水平 ,去除率达 99%
Testing and application of simultaneous nitrification and denitrification in landfill leachate treatment were reported.The sanitary landfill was located in Wujiang, Jiangsu Province.The research & application illustrated that the balance of alkali consuming in nitrification process and alkali producing in denitrification process can be reached in SND,so it is easy and economic to control pH.After bio-treatment with (1～2 mg/L) DO in the first aerobic pond and 3～4 mg/L DO in the second aerobic pound,the ammonia-nitrigon concentration in the effluent was always less than 5 mg/L,the removal rate of ammonia-nitrogen was up to 99 percent.
