Energy-saving and efficient municipal sewage treatment plant construction method
An energy-saving and efficient municipal sewage treatment plant construction method comprises following steps: a, a site is leveled, and a pretreatment section, a secondary biological treatment section, an advanced treatment section, a disinfection section and a sludge treatment section are sequentially constructed; b, constructing a pretreatment section, which comprises a coarse screen, a liftingpump station, a fine screen, an aerated grit chamber, a fine screen, and a primary sedimentation tank; c, constructing a secondary biological treatment section, which comprises an oxidation ditch anda secondary sedimentation tank; the outer pool wall adopts a reinforced concrete structure, and the inner partition adopts a brick wall shear wall structure; d, constructing an advanced treatment section, which comprises a high-density sedimentation tank, a midway lifting pump station and a denitrification active sand filter tank; e, constructing a disinfection section, which comprises a contactdisinfection tank and an effluent discharge open channel; f, constructing a sludge treatment section, which comprises a sludge thickening tank, a sludge dehydrating room and a sludge outward transportation field; g, the raw sewage enters the pretreatment section; the treated sewage enters the secondary biological treatment section, the advanced treatment section; and the disinfection section in sequence, and finally sewage is disinfected and then discharged.
一种节能高效市政污水处理厂建设的方法，按步骤进行：a、平整场地，依次构建预处理段、二级生物处理段、深度处理段、消毒段和污泥处理段；b、构建预处理段：包括粗格栅及提升泵站、细格栅及曝气沉砂池、精细格栅及初沉池；c、构建二级生物处理段：包括氧化沟和二沉池；外池壁采用钢筋混凝土结构，内部隔断采用砖墙剪力墙结构；d、构建深度处理段：包括高密度沉淀池、中途提升泵站、反硝化活性砂滤池；e、构建消毒段：包括接触消毒池、出水排放明渠；f、构建污泥处理段：包括污泥浓缩池、污泥脱水间、污泥外运场；g、原污水进入预处理段；处理后的污水进入二级生物处理段；处理后的污水进入深度处理段；处理后的污水进入消毒段消毒后排放。
