污水厂增加和完善硝化功能的工艺改造探讨

On Renovation to Effect Nitrification Process in Sewage Treatment Works

主要论述了污水厂增加和完善硝化功能改造的途径。讨论了增加和完善硝化功能的机理分析,进行工艺改造的理论计算以及工程措施。通过工程实例说明采用添加浮动填料改造老污水厂,是技术可行、经济上比较合理的工艺改造方法。通过改造,污水处理厂可以增加和完善硝化功能,出水完全可以满足GB18918—2002《城镇污水处理厂污染物排放标准》的要求。

Described hereby is the way to renovate and improve nitrification in the sewage treatment works, with analysis of the mechanism, theoretical calculation and engineering measures thereof. It proves through engineering practice that to renovate the old sewage works by adding floating filler is technically feasible and economically reasonable. The effluent after renovation can fully meet the requirements in GB18918-2002, 'Standard for Discharge of Pollutants from Sewage Treatment Works in Towns and Cities'.
