摘　　要：首先分析了原屠宰废水处理系统存在的问题,调整了工艺路线,增设了水力筛。改造后,系统对COD、BOD5、SS、NH3-N、TP、动植物油的去除率分别达到97.2%、98.3%、92.5%、81.3%、85%、96.3%以上,出水各项指标均达到《肉类加工工业水污染物排放标准》(GB 13457—92)的一级标准,系统运行稳定,耐冲击负荷能力强。The existing problems of the original slaughterhouse wastewater treatment system were analyzed, the wastewater treatment process was improved, and the hydraulic screen was added. After the reconstruction, the removal rates of COD, BODs, SS, NH3 - N, TP and animal and vegetable oils were more than 97.2%, 98.3%, 92.5% , 81.3% , 85% and 96.3% respectively. The effluent quality met the first class criteria specified in the Discharge Standard of Water Pollutants for Meat Packing Industry （GB 13457 -92）. The treatment system had stable operation and a strong resistance to the impact load.
