摘　　要：天津经济开发区第一污水处理厂升级改造工程出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级B标准,其中关键是保证TN、SS和TP达标,而且进水中Cl-浓度较高(1 500 mg/L),处理工艺需在高氯离子浓度下保证良好的处理效果。经比较,确定采用Denite深床反硝化滤池工艺,该滤池充分利用了现有反应沉淀池,具有土建投资省、施工周期短的特点,是污水厂升级改造中的优选工艺。通过中试,验证了Denite在设计条件下出水水质优于一级B标准。The first WWTP in Tianjin Economic Development Zone needs upgrading and retrofitting to meet the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）. The key is to ensure TN, SS and TP to meet the discharge standard. Besides, the influent chloride is pretty high, up to 1 500 mg/L, which requires the treatment process to ensure good treatment effect under high chloride concentration. After comparison, it is decided to adopt deep bed Denite filter technology. The Denite filter fully adopts the existing reaction and sedimentation tank, which leads to very low cost and short construction period. It is an excellent technology for upgrading and retrofitting WWTPs. The pilot test confirms that the effluent quality is better than the first level B criteria.
