不同添加剂对污水处理中丝状菌膨胀的控制作用研究进展

Research Progress on the Control Effect of Different Additives on the Expansion of Filamentous Bacteria in Sewage Treatment

丝状菌膨胀是污水处理过程中面临的一个重要难题,导致丝状菌膨胀的原因有很多。在实际工况运行过程中会采取不同的措施控制丝状菌膨胀,但在紧急情况下,最有效的措施是使用添加剂。根据添加剂作用原理不同分为絮凝剂、杀菌剂、增重剂等。本文综述了不同添加剂对丝状菌膨胀的控制效果和原理,为有效控制丝状菌膨胀提供更全面的应急措施。

The expansion of filamentous bacteria is an important problem in the process of sewage treatment.There are many reasons for the expansion of filamentous bacteria.In the actual operating conditions,we will take different measures to control the expansion of filamentous bacteria.But,in an emergency,the most effective measure is to use additives.According to the principle of action of additives,it is divided into flocculants,fungicides,weighting agents,etc.This paper reviews the control effects and principles of different additives on filamentous bacteria swelling,and provides more comprehensive emergency measures for effectively controlling filamentous bacteria swelling.
