Precipitated mud recovery device for sewage treatment

Abstract

The invention discloses a precipitated mud recovery device for sewage treatment, and relates to the technical field of sewage treatment. The device comprises a conveying belt and a side edge support frame, wherein the top of the side edge support frame is movably connected with a top pressing wheel and a bottom pressing wheel through connecting bearings. According to the invention, by arranging a filter screen, water and precipitate in mud can be separated, clarified water enters a water storage tank through a water receiving plate, and the precipitate is left at the top of the filter screen; by arranging a scraping plate, the precipitate, close to one end of a pressing conveying belt, on the filter screen can be scraped off, and the precipitate can be conveniently pressed into mud cakes through the pressing conveying belt; and by arranging a water receiving plate, filtered water can be collected, the water can drive a rotating water disc to rotate, a moving table moves in a reciprocating mode, and precipitate can be further dried while the precipitate is evenly spread through a partition plate, so that the water content of the precipitate is reduced, and the purpose of facilitating transportation is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sedimentation mud recovery device for sewage treatment. Background technique [0002] Sewage refers to the effluent water from domestic and production that is polluted to a certain extent. Water that has lost its original function is simply called sewage. Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. When the sewage is being treated, the sewage needs to be concentrated in the sewage pool. After enough sewage is stored in the sewage pool, the sewage is sent to the sewage purification device through the sew...

Problems solved by technology

[0003] Although the clarified sewage in the sedimentation tank can be pumped out with a water pump, a large amount of sediment forms mud in the sedimentation tank, which is very difficult to handle and utilize, mainly because the mud contains a large amount of water in the mud, and when the
