摘要
靖江市城市污水处理厂一期工程(4×104m^3/d)经过提标改造,已稳定运行1年多,出水水质稳定达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,对COD、SS、NH_3-N、TN和TP去除率分别为87%、90%、87%、55%和89%。此外,针对运行过程中出现的出水TN和SS个别时段超标等问题,提出了优化运行管理建议。
More than a year has passed since the upgrading and reconstruction project with capacity of 4 ×10^4 m^3/d of Jingjiang Municipal Sewage Treatment Plant was put into operation. The effluent quality could meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）. The removal rates of COD, SS, NH3 -N, TN and rip were 87%, 90%, 87%, 55% and 89% respectively. In view of that the effluent concentrations of TN and SS exceeded the requirement of the standards in a few cases during operation periods, some recommendations for optimizing the operation and management were put forward.
