摘要
温岭市某污水处理厂一期工程设计规模0.5×104 m3/d,生物处理采用SBR工艺,出水执行《城镇污水处理厂污染物排放标准》(GB18918-2002)一级B标准。本期工程包括改建、扩建两部分,改建工程规模为0.5×104 m3/d,将原SBR池改建为二级AO池,扩建工程规模为0.5×104 m3/d,采用厌氧/二级AO工艺,并新建1.0×104 m3/d深度处理段(采用高效沉淀池、反硝化深床滤池工艺)。此次提标扩建后总处理规模达到1.0×104 m3/d,出水达到准地表Ⅳ类排放标准。
The design scale of the first phase of a wastewater treatment plant in Wenling City is 0.5×10^4 m^3/d, and SBR is used for biological treatment. The effluent quality was required to met the first level B criteria in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（GB 18918-2002）.Upgradation and Reconstruction are the main two parts of this project. The scale of the reconstruction project is 0.5×10^4 m^3/d, and convert SBR pool into a secondary AO pool. While the next reconstruction project scale is 0.5×10^4 m^3/d., used with anaerobic/secondary AO technology. And new 1.0×10^4 m^3/d advanced treatment section is built by using High-efficiency Precipitation Tank and Denitrification Deep Bed Filter Process. After this subproject, the total treatment scale will reach 1.0×10^4 m^3/d, and the effluent quality will meet the Quasi-Ⅳ Standards.
