Phoredox+高效沉淀组合池用于集约型污水处理厂工程设计

Design of intensive WTTP with phoredox and high-density sedimentation combined tank

临沂市国际生态城污水处理厂设计规模2万m^(3)/d,采用成熟稳定的Phoredox+高效沉淀池工艺,出水水质达到《城镇污水处理厂污染物排放标准》一级A排放标准。因该项目工期紧、用地少且预算有限,所以生化池和深度处理单元采用半地下一体化设计,达到了节省占地、低成本建设运行的双重目的。介绍了设计水量、水质,工艺设计要点和设计亮点。

The design capacity of International Eco-city Wastewater Treatment Plant in Linyi city is 2×10^(4)m^(3)/d.Phoredox+hign-density sedimentation tank process was adopted and the effluent had been superior to the first level Class A of the Discharge standard of pollutants for municipal wastewater treatment plant.As the tight schedule,land shortage and limited budget,the biological reactor and advanced treatment units were adopted a semi-underground integrated arrangement,which achieved the dual purposes of low occupation and low-cost construction.Design water quantity,quality,key points and highlights were introduced in detail.Technical references were provided for similar wastewater project which is limited by occupation and cost.
