气浮-水解酸化-生物接触氧化-MBR工艺处理厨房污水

Air Floatation-Hydrolysis Acidification-Biological Contact Oxidation-MBR Process for Treatment of Kitchen Sewage

介绍了采用气浮-水解酸化-生物接触氧化-MBR工艺处理食堂厨房污水工程实例。工程实践表明,当污水中COD为458~598 mg/L、SS为4962~8713 mg/L、动植物油为≤630 mg/L时,该工艺运行稳定,出水水质可稳定达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级B标准排放要求。

The engineering application of air floatation-hydrolysis acidification-biological contact oxidation-MBR processes for the treatment of kitchen sewage was presented. When the influent COD about 458~598 mg/L, SS about 4962~8713 mg/L, animal fats and plant oils≤630 mg/L, engineering practice shows that the processes was stable running, the effluent quality can stable reach the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).
