城市污水处理厂动态模拟研究

Study on Dynamic Simulation of Municipal Sewage Treatment Plant

利用活性污泥1号模型,对采用A/O工艺的上海某城市污水处理厂的碳化、硝化、反硝化过程进行计算机动态模拟。结果表明,出水中的TCOD、TN与污水处理厂的出水基本吻合,说明利用活性污泥1号模型对城市污水处理厂进行模拟是可行的,并根据模拟结果建议该厂运行过程中应降低A段的溶解氧。

One of the sewage treatment plants in Shanghai was adopting A/O treatment process, its carbonization, nitrification and denitrification were dynamic simulated by activated sludge model No 1. The results tallied well with the actual data of effluent, such as TCOD and TN, so that sewage treatment plant simulated by ASM1 was feasible. According to the simulating results, concentration of DO should be decreased.
