摘要
采用接触氧化/沉淀/气浮工艺对屠宰废水进行深度处理。该工艺可以强化对氨氮和总磷的去除,使出水水质达到《污水综合排放标准》(GB 8978—1996)的二级标准。分析了调试中异常情况出现的原因,找出了处置方案,并提出以进水后接触氧化池内溶解氧随时间的变化规律和接触氧化池出口处的SV值作为判断生化工段成熟的标准。
Biological contact oxidation/sedimentation/air flotation process was used for slaughterhouse wastewater advanced treatment. The process could enhance ammonia nitrogen and TP removal, and enabled the effluent quality to meet the second class criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 -1996）. The cause of abnormal phenomenon in the commissioning was analyzed, and the handle scheme was provided. It was proposed that the time-varying rule of dissolved oxygen in biological contact oxidation tanks and SV value at the outlet served as a criterion of biological section maturation.
