不同碳氮比条件下小型规模污水处理厂的运行模式分析研究

以4个小型规模的污水处理厂为经营实例，探讨了进水的碳氮比例长期维持在高碳高氮、高碳低氮、低碳高氮和低碳低氮4种条件下，每种特征进水会对污水处理厂的运营所造成的困难。强调了如何运用工艺调整和成本控制，选择适宜的运行模式，用以优化污水处理厂的经营工况，在确保生化系统稳定运行的同时，使之达到水务行业内正常的毛利率水平，具有推广和应用的价值。

Operating Mode Analysis of Small Scale Sewage Treatment Plant Under Different Carbon and Nitrogen Ratio Conditions

This paper takes four small scale sewage treatment plants as the operating examples to discuss the inlet under four conditions chronically, such as high carbon and high nitrogen, high carbon and low nitrogen, low carbon and high nitrogen, low carbon and high nitrogen, and the difficulty of the sewage treatment plant actual operation caused by each influent condition .It fo-cus on the cost control values of selecting appropriate operating mode and its values to optimize the operating conditions of sewage treatment plant.While ensuring the stable operation of the biochemical system, the method achieves the normal gross margin lev-els within the water industry, having application values.
