摘要
邢台市污水厂升级改造工程采用AAO工艺,设计出水水质由原来的《城镇污水处理厂污染物排放标准》(GB 18918—2002)的二级标准提高到一级A标准。分析了原处理工艺存在的主要问题及改造后取得的效果,并详细介绍了改造工程的工艺流程和设计参数。实际运行效果表明,出水水质稳定达到设计标准,可为类似污水处理工程改造提供参考。
The upgrading and reconstruction project of Xingtai WWTP adopts AAO process, the effluent quality is upgraded from the second class to the first class A criteria specified in Discharge Stand- ard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918 - 2002）. The main questions of the original process and the results after reconstruction are analyzed, and the technological processes and the design parameters of the reconstruction project are described. The operational results show that the effluent quality meets the design discharge standard. The project can provide reference for reconstruction of similar wastewater treatment projects.
