摘　　要：本实验研究AF(厌氧生物滤池)+SBR(序批式活性污泥法)组合工艺对屠宰废水的处理效果,为屠宰废水处理提供一种科学经济有效的方法。AF+SBR组合工艺以3L/T的流量进水,总HRT为24h,厌氧12h,好氧12h,曝气量保持在30L/min,对屠宰废水的CODcr,NH4+-N,TP,TKN(凯氏氮)去除效果进行分析研究。实验结果表明,CODcr,NH4+-N,TP和凯氏氮去除率分别可达90%,95%,70%,90%,各项出水指标均达到了农田灌溉的标准。In order to provide a scientific,economic and effective method for slaughterhouse wastewater treatment,the effect of the AF+SBR process on the butcher waste water was studied.The removal effect of CODcr,NH4-N,TP and TKN were analyzed in experiments by controlling the inflow and HRT of the AF +SBR process in 3L/T and 24h,under aerobic and anaerobic conditions for 12h with aeration intensity at 30L/min.The results showed that the removal rate of CODcr,NH4-N,TP and TKN can be expected to reach 90%,95%,70% and 90%,respectively.The test indicated that all effluent quality indexes have reached farm irrigation water standard.
