摘　　要：以杭州某大型生活垃圾焚烧厂渗滤液处理站为例,通过监测垃圾焚烧厂渗滤液指标全年变化,研究垃圾焚烧厂渗滤液季节性变化特征。对渗滤液产生量及渗滤液pH、COD、氨氮以及渗滤液沼气产量变化进行分析探讨,以期提高渗滤液处理效率。结果表明,垃圾焚烧厂渗滤液pH、COD、氨氮受季节影响较大,呈现出明显的季节性差异;焚烧厂渗滤液月产生量范围为26 000~39 219 t,吨渗滤液沼气产量范围为19.0~31.8 m^(3)。The leachate treatment station of a large domestic waste incineration plant in Hangzhou was taken as an example.By monitoring the annual variation of leachate index of waste incineration plant,the seasonal variation characteristics of leachate was studied.In order to improve the treatment efficiency of leachate,the variation of pH,COD,ammonia nitrogen and biogas production of leachate were analyzed and discussed.The results showed that the pH,COD and ammonia nitrogen of the leachate of the waste incineration plant were greatly affected by the seasons,showed obvious seasonal differences.The monthly output of leachate of the incineration plant ranges from 26000 to 39219 tons,and the biogas produced by a ton of leachate ranged from 19.0 to 31.8 m^(3).
