摘　　要：目前,大多数城市污水处理厂仍采用传统的活性污泥法工艺进行城市污水处理,该工艺需要使用大量的化学药剂来提高污水处理中的脱氮效果,导致污水处理效率降低、能耗增加。为了解决该问题,基于Anammox技术对传统的活性污泥法工艺进行了改良,在工艺流程中使用厌氧池、好氧池和厌氧氨氧化池替代曝气池,使用亚硝酸处置工艺完成污水脱氮,分析表明,新型的活性污泥法工艺能够有效提高污水处理的脱氮性能,降低能耗。At present,most urban sewage treatment plants still use the traditional activated sludge process for urban sewage treatment,which requires the use of a large number of chemicals to improve the nitrogen removal effect in sewage treatment,resulting in the reduction of sewage treatment efficiency and the increase of energy consumption.In order to solve this problem,the traditional activated sludge process is improved based on Anammox technology.In the process,anaerobic tank,aerobic tank and anammox tank are used to replace aeration tank,and nitrite treatment process is used to complete wastewater denitrification.The analysis shows that the new activated sludge process can effectively improve the denitrification performance of wastewater treatment and reduce energy consumption.
