【摘要】 利用二级混凝沉淀+机械过滤器法处理含磷废水,通过做pH、CaCl2的投加量对除磷处理效果影响的小试,确定混凝沉淀最佳条件为pH值为11和CaCl2投加量100mg/L。工程运行现状表明:该法处理磷化废水是可行的,出水能够达到国家污水综合排放标准(GB8978-1996)一级排放标准。更多还原

【Abstract】 A method of serial coagulating sedimentation and mechanical filtering is adopted to treat phosphorus wastewater,the effect of pH and the CaCl2 dosage on phosphorus removal is done through a small scale experiment,the best process conditions are pH 11 and the dosage of CaCl2 100 mg/L.The current operating situation showed that: the method is feasible in phosphorus wastewater treatment,the treated water meets the national integrated wastewater discharge standard(GB8978-1996) level 1 emission standard.更多还原
