摘　　要：针对包头市污水处理厂进水B/N值低、出水TN要求高的特点,选择改良A2/O工艺为污水处理工艺,并严格控制生物池的DO和ORP值,实现污水的短程硝化反硝化,降低能耗。在进行污水厂设计时,要合理设计初沉池,以充分利用原水中的碳源,减少或避免外加碳源;此外,还要合理选择内回流比,以降低运行成本和基建投资。Because of low influent B/N value and high requirement of effluent TN of WWTP in Baotou City, the modified A2/O process was selected as the wastewater treatment process, and the DO and ORP values of the biological pool was strictly controlled to achieve short-cut nitrification and denitrification of wastewater and reduce energy consumption. During the process design, the primary sedimenta- tion tank should be reasonably designed to make full use of carbon source in the raw wastewater and reduce or avoid additional carbon source. In addition, the internal reflux ratio should be reasonably chosen to reduce the operation costs and the capital investment.
