摘 要:MBR又称膜生物反应器,该技术汇集了活性污泥法、膜分离法的优势,近年来被广泛应用于城镇污水处理与回用领域,多个工程化废水处理案例表明MBR处理效果颇佳。本文对MBR技术进行改良,采用改良型一体化MBR设备处理畜禽宰杀废水,工程化运行结果表明,采用改良型一体化MBR设备能够有效处理生活污水,且COD、氨氮、总磷浓度平均去除率均高于95%,满足《地表水环境质量标准》(GB 3838—2002)中的准Ⅳ类标准,本研究为畜禽宰杀废水处理提供重要的参考。MBR,also known as membrane bioreactor,brings together the advantages of activated sludge method and membrane separation method,and has been widely used in the field of urban sewage treatment and reuse in recent years.A number of engineering wastewater treatment cases show that MBR treatment effect is quite good.In this paper,the MBR technology is improved,and the improved integrated MBR equipment is used to treat livestock and poultry slaughter wastewater.The engineering operation results show that the improved integrated MBR equipment can effectively treat domestic sewage,and the average removal rate of COD,ammonia nitrogen and total phosphorus concentration is higher than 95%.It meets the quasi-Ⅳstandard in the"Surface Water Environmental Quality Standard"(GB 3838—2002),and this study provides an important reference for the treatment of livestock and poultry slaughter wastewater.
