摘要
水产废水具有悬浮物高、有机物浓度高、氨氮总磷浓度高等特点。采用隔油沉淀-曝气调节-混凝气浮-A2/O的处理工艺,当进水COD≤2200mg·L-1,NH3-N≤80mg·L-1时,出水基本达到综合排放标准二级标准。工程实践表明,该工艺流程处理效果良好、运行成本较低、操作简便。
The waste water from the sea food company features high density of floats, organic compound as well as the ammonia based nitrogen and total phosphor. By treating it through the procedure like greasy segregating, precipitating, air blowing, conglomerating and A^2/O, the discharged water quality can meet the requirement of level 2 for the general dischages and quite a few index can even meet the middle water standard if we assume that the waste water before treatment is composed of COD no higher than 2 200 mg·L^-1 and NH3-N no higher than 80 mg·L^-1. It proved by the practices that such treatment procedttre is cost saving and easy to operate but works with good results.
