The invention relates to a combined type integrated
sewage treatment device. The combined type integrated
sewage treatment device comprises an anaerobic tank, an aerobic tank and a
sedimentation tank, wherein an inspection well is mounted at the top end of each of the anaerobic tank, the aerobic tank and the
sedimentation tank; a water inlet and a water outlet are respectively formed in the two sides; the anaerobic tank, the aerobic tank and the
sedimentation tank comprise top plates, bottom plates, side plates, vertical plates, a
clapboard and first bolts; the top plates, the bottom plates, the side plates, the vertical plates and the
clapboard are made from templates, stay tubes, second bolts and frames; sealing strips are arranged all around the top plates, the bottom plates, the side plates, the vertical plates and the
clapboard; the cross section of each of the templates adopts a
periodic wave shape. The combined type integrated
sewage treatment device provided by the invention can be produced in a factory regardless of the treating amount, and standardized and automatic pipelined production can be realized, so that the cost is greatly reduced, the
production rate is improved, and the device has relatively good economic and technical benefits. The invention also discloses a mounting method of the combined type integrated
sewage treatment device.
