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.
