摘　　要：试验考察了矿化垃圾生物反应床工艺处理奶牛场废水出水水质与配水负荷的关系。试验研究表明，出水CODcr、NH4-N浓度分别与配水负荷呈线性和指数相关；TN的去除率仅为60％左右，是选择最佳配水负荷的限制性因素；综合考虑废水处理能力和NO3-N的反硝化，配水速率可以保守选择0．09～0．11cm／h。The relationship between effluent water quality and wastewater load were investigated in the treatment of livestock wastewater by aged refuse bioreactor.The concentration of COD_(cr) and NH_4-N in effluent are in linear and exponential dependence on wastewater load respectively;TN removal is the limiting factor in selection of optimal wastewater load,which is only 60% and much lower than COD_(cr) and NH_4-N removal,the suitable hydraulics load of aged refuse bioreactor is 0.09~0.11 cm/h in consideration with wastewater treatment capacity and the nitrate denitrification.
