摘　　要： 采用SBR反应器对垃圾渗滤液和市政粪水的混合液进行处理研究,研究了垃圾填埋场垃圾渗滤液与市政粪水混合处理的可行性。实验过程中COD、BOD5、TN、NH4+-N和TP的平均去除率分别达到93.76%、98.28%、84.74%、99.21%和54.80%,相应的污泥(SS)平均去除负荷为0.24、0.08、0.04、0.036和0.000 41 kg/(kg.d)。结果表明,粪水的混入可有效提高垃圾渗滤液的可生化性,渗滤液和粪水的混合处理效果良好,但反应器出水COD浓度仍略高,反应器对TP的去除效果一般。 A sequencing batch reactor（SBR） is used to treat landfill leaehate containing high concentration of ammonium nitrogen with municipal fecal supematant in order to emamine the feaslbility of biologically treating a mixed wastewatar of landfill leachate and municipal fecal supermatant. The results indicates that the average removal efficiencies of COD, BOD5,TN and NH4^＋ - N and TP are 93.76%, 98.28%, 84.74 %, 99.21% and 54.08 % respectively and the corresponding average sludge removal loading rates of COD, BOD5, TN and NH4^＋ - N are 0.24,0.08, 0.04,0.036 and 0.00041 kg/（kg·d） respectively. The addition of fecal supematant successfully increases the COD/NH4^＋ - N ratio of landfill leachate. Mixed wastewater of landfill leachate with fecal supematant is successfully treated in a sequencing batch tractor system. However COD in effluent is still a little high and TP removal efficiency is not well in the study.
