AO结合循环式活性污泥法处理海产品加工废水

Treatment of seafood processing wastewater by A/O and CASS process

针对海产品加工废水氨氮含量较高的特点,舟山兴业有限公司的污水处理工程采用两段A O结合循环式活性污泥法工艺,工程验收合格后运行一年多来,排放废水的各项污染指标均达到国家《污水综合排放标准》(GB8978—1996)的二级标准,处理系统具有很好的抗冲击能力和脱氮效果。

Zhoushan Xingye Industrial Co.,Ltd.uses the 2sect A/O process and CASS(cyclic activated sludge system) process to treat the seafood processing wastewater,because the wastewater contains high ammonia and nitrogen. During more than one year's running after the technology had passed the Evaluation and Exam given by the authorized management organization,the discharged water meets the National Integrated Wastewater Discharge Standard(GB8978-1966). The antiimpact of the system is good, and it also has good denitrogen effect.
