摘　　要：介绍了某垃圾焚烧发电厂渗滤液厌氧出水的处理工程,采用立体式厌氧/好氧反应池处理工艺。对反应池启动和调试过程中污染物的去除效果进行了分析。结果表明,当处理负荷为COD 1.8 kg/(m3·d)和NH3-N 0.36 kg/(m3·d)左右时,出水COD和NH3-N质量浓度分别低于1 900 mg/L和180 mg/L,两者去除率分别高达80%和90%左右。经过120 d满负荷运行,反应池展现出较好的抗冲击负荷能力,出水指标均达到设计要求,经过后续MBR处理可以达到3级排放标准。该工程能够有效节约占地面积。This manuscript introduced the treatment project for anaerobic effluent of landfill leachate from a waste incineration plant.A vertical anaerobic/aerobic reactor was used in the project,which could reduce the floor space.Contaminant removals during the reactor＇s startup and commissioning were investigated.The results showed that the effluent COD and NH3-N concentrations were respectively below 1 900 mg/L and 180 mg/L when the processing loads were around 1.8 kg COD/（m3·d） and 0.36 kg NH3-N/（m3·d）.And the removal efficiencies of COD and NH3-N were respectively reached at 80％ and 90％.The reactor exhibited a good resistance to impact load,and the effluent complied with design requirements after 120 d full-load operation.Moreover,the third grade criteria specified in the Discharge Standard of Integrated Wastewater could be reached via subsequent treatment using membrane bioreactor.
