MBR在屠宰废水处理中的工程应用

摘要

采用AAO＋MBR工艺处理屠宰废水,运行结果显示,针对屠宰废水的高浓度有机物污染,该工艺能够稳定运行,对CODcr,BOD5的去除率超过95%,TN去除率80%以上,出水水质达到了《城镇污水处理厂污染物排放标准》（GB18918-2002）中的一级A标准,出水经过消毒进入企业后可循环使用。%AAO＋MBR process was used for slaughter water treatment.The operation result shows that in spite of high concentration of organics in influent,the process operates stably,with removal rate of CODcr and BOD5 more than 95%,TN more than 80%,and the effluent comes up to A of I-class criteria specified in the Integrated Wastewater Discharge Standard（GB 18918-2002）.The effluent can be reused for the company after disinfection.
