Abstract

The invention discloses a small-sized sewage treatment ship type precipitation pool device. The small-sized sewage treatment ship type precipitation pool device comprises a ship body; a control switchis arranged on the outer side surface of the ship body; the input end of the control switch is electrically connected with the output end of an external power supply; a flocculation box is arranged on the left side of an inner cavity of the ship body; a precipitation box is arranged on the right side of an inner cavity of the ship body; the precipitation box is a semi-spherical shell; an inflowing pipe communicated with a flow stabilizing box is arranged in the precipitation box; an outflow pipe running through the right side surface of the ship body is arranged on the right side of the upperend of the precipitation; the ship body is transversely partitioned into a reaction box, the flow-stabilizing box and the precipitation box; the reaction box, the flow-stabilizing box and the precipitation box are mutually communicated to form a communication device; the sewage enters from a first partition plate and the left side surface of the ship body, and sequentially and transversely penetrates through the reaction box, the flow-stabilizing box and the precipitation box; and flocculate and sludge in the sewage are separated through layering and classification. The small-sized sewage treatment ship type precipitation pool device is compact in structure, reduces the total volume of the ship body, accelerates completion of the precipitation work, increases the daily sewage treatment quantity and can effectively cooperate with an oxidation ditch to perform muddy water separation.

Description

Technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to a small sewage treatment ship-type sedimentation tank device. Background technique

[0002] The integrated oxidation ditch wastewater treatment process is currently used for small-scale sewage treatment. The solid-liquid separation device of this process is mainly ship type, but the existing sedimentation tanks generally have large area, high construction and operation costs, long residence time, and mud buckets. Poor sludge discharge, "sludge running" on the effluent weir, etc., the low space utilization rate of the sewage tank, resulting in an excessively large hull, lowering the treatment efficiency, and inconvenient operation and use. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the existing shortcomings and provide a small sewage treatment ship-type sedimentation tank device with compact structure, layered st...
