摘　　要：通过投加片碱调节PH值,投加氯化钙生成磷酸钙、羟基磷酸钙沉淀,从而达到对总磷的去除。本研究主要探讨相同片碱、氯化钙的投加量,不同的投加顺序对比总磷的去处效果、反应机理、加药前后的PH值变化、混凝沉淀效果等。分析两种不同加药顺序的优缺点,为含磷废水处理提供参考。The addition of calcium chloride to form calcium phosphate and calcium phosphate precipitation was carried out by adding the addition of calcium chloride to the removal of total phosphorus.In this study,we investigated the effects of the same amount of caustic soda and calcium chloride on the effect of total phosphorus addition,the reaction mechanism,the change of PH value before and after dosing,and the effect of coagulation and sedimentation.The advantages and disadvantages of two different dosing sequences were analyzed,which could provide reference for the treatment of phosphorus-containing wastewater.
