水解酸化-MBR组合工艺处理雏鸡孵化场废水

Treatment of Chick Hatchery Wastewater by Hydrolytic Acidification-MBR Combination Process

文章介绍了采用水解酸化-MBR组合工艺处理雏鸡孵化场废水的应用实例。结果表明,当进水COD、BOD5、NH3-N和SS浓度分别为1230、268、22和456 mg/L时,污染物去除率依次分别为96.7%、97.5%、82.7%和98.6%。经该工艺处理后的出水水质稳定,并达到了《城镇污水处理厂污染物排放标准(GB 18918—2002)》一级A标准。

The chick hatchery wastewater treatment by a hydrolytic acidification and membrane bio-reactor(MBR)combination process is studied in this paper.The result indicates that the removal rates of COD,BOD5,NH3-N and SS are 96.7%,97.5%,82.7%and 98.6%with the influent concentrations of 1230,268,22 and 456 mg/L.The water quality of the effluent is stable and achieves the grade A in first class classified in the"discharge standard of pollutants for municipal wastewater treatment plant(GB 18918—2002)".
