摘　　要：该文以ASM2D模型为基础,针对上海某特大型污水处理厂开展仿真模拟研究,通过模拟分析温度、HRT、曝气分数、泥龄和DO等影响该大型污水处理厂硝化效能提升的因素,结合污水处理厂运行现状提出基于曝气分数调整的优化运行策略。结果表明通过对污水处理厂缺氧区间隙供氧,使污水处理厂的曝气分数提高至75%,可大幅度提升该特大型污水处理厂的冬季硝化能力和总氮去除能力。Based on ASM2D model, the simulation modeling for super large scale wastewater treatment plant in Shanghai was carded out. The influence factors on nitrification such as temperature, HRT, aeration fraction, SRT and DO were simulated and the optimized operation strategy on the basis of increasing aeration fraction was proposed. The results show nitrification capacity and TN removal rate of the super large scale wastewater treatment plant can be enhanced by interval aeration in the anoxic zone when aeration fraction of whole plant is improved to 75%.
