摘　　要：南方某城镇集中了较大规模的肉类农产品加工企业。这些企业排放废水量大,有机物浓度高。该城镇采用经企业预处理后集中处理方式,以降低运行成本。采用A/O-SBR的二级强化生物处理工艺,经近2年的运行表明:COD、BOD、动植物油类及悬浮物的去除率高,出水达到GB13457-92《肉类加工工业污染物排放标准》,为当地肉类联合加工企业废水治理解决了一大难题。Larger enterprises of meat processing and agricultural products are concentrated in a southern town,whose wastewater is large in quantity with high concentration of organic matters.Concentrate treatment ways are used to do pretreatment to reduce operating costs.The enhanced secondary biotreatment of A/O-SBR is then used.Nearly two years of operation show that the removal rates of COD,BOD,animal oil and suspended solids are high.The effluent can meet GB13457-92 ＂The Industrial Pollutant Discharge Standards for Meat Processing＂.
