2 G 镇生活污水同步生物脱氮除磷 A /O 工艺设计 摘 要：随着城镇经济的快速发展和城镇人口的快速增长，生活用水量逐年增大，与 此同时生活污水带来的污染问题也愈发严重，因此，建设适合城镇的污水处理 2 厂就显得十分重要。本设计针对于 G 镇的生活污水，使用 A /O 脱氮除磷工艺， 通过对格栅、沉淀池、生化反应池、污泥浓缩池等设施的计算与设计对污水进 行有效处理，使处理后的出水水质达到《城镇污水处理厂污染物排放标准》 （GB18918-2002 ）一级A 标准。 2 关键词：A /O 工艺；脱氮除磷；生活废水；污水处理设施 1 Process Design of Synchronous Biological 2 Denitrification and Phosphorus Removal A / O of Domestic Sewage in G Town Abstract ：With the rapid development of urban economy and the rapid growth of urban population, the domestic water consumption increases year by year. Meanwhile, the pollution problem brought by domestic sewage becomes more and more serious. Therefore, it is very important to build a sewage treatment plant suitable for urban 2 areas. This design is aimed at the domestic sewage in G town, using A /O denitrification and dephosphorization process, through the grid, sedimentation tank, biochemical reaction tank, sludge concentration tank and other facilities of the calculation and design of the effective treatment of sewage, so that the treated effluent quality to meet the urban sewage treatment plant pollutant discharge standard (GB18918-2002) A standard. 2 Key words: A /O process; denitrification and dephosphorization; domestic wastewater; sewage treatment facilities. 2 2 G 镇生活污水同步生物脱氮除磷 A /O 工艺设计
