摘　　要：上海嘉定再生能源有限公司渗滤液处理后,出水存在总氮严重超标的问题。有必要采集其连续运行时间段内O罐和A罐进水的各生化指标,分析其总氮超标的主要原因。通过一段时间的加强排泥、确定外加碳源添加量等调整措施,总氮在调整初期10 d内由660 mg/L降到150 mg/L左右。最后,通过适当调整外加碳源量,系统出水总氮达到了预期标准。After treating the leachate of Shanghai Jiading Renewable Energy Co.,Ltd.,the effluent has a problem that the total nitrogen seriously exceeds the standard.It is necessary to collect the biochemical indicators of the influent from tank O and tank A during its continuous operation period,and analyze the main reasons for its total nitrogen exceeding the standard.Through adjustment measures such as strengthening sludge discharge and determining the amount of added carbon source for a period of time,total nitrogen decreased from 660 mg/L to about 150 mg/L within 10 days of the initial adjustment.Finally,by properly adjusting the amount of external carbon source,the total nitrogen in the effluent of the system reached the expected standard.
