摘要
随着经济的发展和人们对生态环境的重视,城市污水处理厂对氮、磷等排放指标要求逐步提高,然而对于低碳高氮污水来说,需要通过投加乙酸钠等外加碳源来提高常规脱氮工艺的反硝化水平。本文通过工程实例,介绍污水处理厂中乙酸钠加药间的设计要点,为今后完善乙酸钠加药间的设计方法提供借鉴意义。
With the rapid economic development and the rising concerns for the environment, the nitrogen and phosphorus discharge standards in the municipal sewage treatment plants improve stage by stage. CH3 COONa dosing is a carbon source to im- prove the level of the denitrification of the sewage with low carbon and high nitrogen. Based on actual conditions of projects, this paper analyzes the design methods and principles of the CH3 COONa dosing room. It provides reference to improve the design level of CH3COONa dosing room and perfect the design method.
