泰安市第四污水处理厂的调试运行

Tai'an City,the fourth sewage treatment plant commissioning operation

泰安市第四污水处理厂采用改良的AAO工艺处理城市污水。建成后于2016年2月1日开始进水调试,于2016年6月20日顺利调试结束,水质达到一级A排放标准。调试初期,由于水温较低,活性污泥的培养驯化速度比较慢,出水效果不理想,在调试后期,随着水温的上升,出水的COD、BOD_5、氨氮、总磷及SS的值均达到设计标准。

Tai’an Fourth Sewage Treatment Plant adopts a modified AAO process to treat municipal wastewater.Upon completion of the project,water commissioning will begin on February1,2016and will be successfully commissioned on June20,2016.The water quality will meet Grade I A emission standards.In the early stage of commissioning,due to the low water temperature,the culture and acclimation of activated sludge was slow and the effluent effect was not satisfactory.In the later stage of commissioning,the effluent COD,BOD5,ammonia nitrogen,total phosphorus and SS reached the design as the water temperature increased standard.
