摘要
对工程规模200 m3/d的养殖废水处理工艺进行了改进,主要对厌氧接触池及沉淀池进行了增加填料和MBR的改进。工艺改进后的运行结果表明,对主要污染物的去除率均可以达到90%以上,出水水质可达到污水综合排放标准(GB 8978-1996)二级排放标准的要求。运行成本为1.54元/m3废水,工程实践表明,改进后的处理工艺在养殖废水应用及改进方面有良好的应用前景。
The aquaculture wastewater treatment process of 200 m^3/d was improved,and the packing and MBR were increased in the anaerobic contact pool and settling basin.Running results of the improved process showed that the removal efficiency of the main pollutants could reach above 90%,and effluent water quality could reach the secondary class emission requirements of Integrated Wastewater Discharge Standard（GB 8978-1996）.Operation cost was 1.54 yuan/m^3 wastewater,and engineering practice showed that the improved process hold a good promise in the application and improvement of aquaculture wastewater treatment.
