The invention discloses an integrated
sewage treatment device. The integrated
sewage treatment device comprises a shell, wherein an anaerobic
pool, a contact
oxidation pond I, a primary anoxic pond, acontact
oxidation pond I, a secondary anoxic pond, a contact
oxidation pond III and a
settling tank are successively arranged in the shell, and are successively connected through flow guiding tubes.The shell is provided with a water inlet tube, and the water inlet tube is separately connected with the anaerobic
pool, the primary anoxic pond and the secondary anoxic pond in parallel; the bottom of the contact oxidation pond I, the bottom of the contact oxidation pond II and the bottom of the contact oxidation pond III are separately connected with
aeration; a
sludge discharge pipeline is arranged in the
settling tank, and an outlet of one end of the
sludge discharge pipeline is connected with the anaerobic
pool; an outlet of the other end of the
sludge discharge pipeline is connected witha sludge collecting pond; the upper side of an inlet of the bottom of the sludge discharge pipeline is connected with an air-lift
pipe with an upward outlet, and under driving of negative pressure ofair, sludge on the bottom of the
settling tank is discharged from the sludge discharge pipeline. The integrated
sewage treatment device is low in
energy consumption, high in production efficiency andgood in
treatment effect.
