摘　　要：我国已建成三千八百多座污水处理厂,总处理规模达到1.6亿m3/d,提升现有设施处理效能意义重大。现以典型A/A/O工艺为对象,通过建立基于ASM2D的污水处理过程仿真平台,模拟水温、水质、泥龄、曝气分数、溶解氧浓度等因素对异养菌、聚磷菌和自养菌浓度的影响,并据此建立了功能菌群结构调控策略,为解决脱氮除磷碳源不足和低温硝化容量不足问题提供技术依据,从而保障污水处理厂稳定达标运行。There are more than 3 800 wastewater treatment plants built in China. The total treatment scale has been 160 000 000 m3/d. It is very important to upgrade the treatment efficiency of the existing facilities.Taking the typical A/A/O technology as the object, the article introduces the establishment of the simulation platform of wastewater treatment process based on ASM2 D to simulate the influence of water temperature,water quality, sludge age, aeration fraction, dissolved oxygen concentration on the concentrations of heterotrophic bacterium, phosphorus accumulating bacterium and autotrophic bacterium. Accordingly, the control strategy of functional bacteria structure is built in order to provide the technical basis of solving the shortage of carbon source for nitrogen and phosphorus removal, and the shortage of low temperature nitrification capacity, which can ensure the wastewater treatment plant stable up to standard operation.
