摘　　要：通过对天津滨海新区某工业园区污水处理厂的实地研究和调查,发现该厂进水水质存在"两高一低("难降解COD和TP浓度高、BOD5浓度低)等问题,出水COD、TN、TP和TSS浓度均不能稳定达到《城镇污水处理厂污染物排放标准(》GB 18918—2002)的一级排放标准。为提高工业园区污水厂出水水质,在该厂生物处理的基础上,通过增设辅助工艺和投加药剂等措施使出水水质能稳定达到一级排放标准。In the investigation of sewage treatment plant located at an industrial park in Tianjin E- conomic-Technological Development Area （TEDA） , problems such as high refractory COD, high TP and low BOD5 in the influent were found. COD, TN, TP and TSS in the effluent could not meet the first level criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918- 2002）. In order to improve the effluent quality, based on the biological treatment, measures such as addition of treatment process and dosing of activated carbon and polyaluminum chloride （ PAC ）were taken. As a result, the effluent quality achieved the first level criteria.
