| Abstract: | 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. |
