摘　　要：污水处理厂脱氮除磷处理中,在各个工艺环节需要投加化学药剂。着重介绍了反硝化的碳源、生物除磷中挥发性脂肪酸、碱度、化学除磷药剂中的各种药剂投加方法的基本原理、投加量计算、操作要求以及投加量的控制。During the treatment of nitrogen and phosphorus removal in sewage treatment works,chemical agent should be dosed at different technology stages. The paper introduces the carbon source of denitrification,volatile fatty acid during biological phosphorus removal and alkalinity. Meanwhile,the basic principle,the dosage calculation and con trol and operation requirement of different chemical agent dosing methods are presented by the author.
