The invention discloses sewage internal cleaning equipment capable of moving reversely. The sewage internal cleaning equipment structurally comprises a sewage pipeline, a grating, a water collecting tank, a water inlet, a water conveying pipeline, a booster pump, a grit chamber, an aeration tank, an air hole, a secondary sedimentation tank, a return pipe, a sand discharging opening, a coagulatingtank, an agent pouring opening, a sedimentation tank, a filtering tank, a filtering plate and a water discharging opening; the grating is arranged on the sewage pipeline; the water collecting tank isconnected with the sewage pipeline; the water inlet is formed in the water collecting tank; and the water conveying pipeline is connected with the water collecting tank. According to the sewage internal cleaning equipment disclosed by the invention, suspended matter in sewage are filtered twice by adopting the grating and the grit chamber, colloid and soluble organic matter in the sewage are treated by adopting an activated sludge method, finally, the sewage reaches the discharge standard by coagulating, precipitating and filtering, and a physical method is adopted in the whole process, so that new pollution hidden dangers are avoided.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage internal cleaning device with reverse movement. Background technique [0002] The integrated sewage treatment equipment is a device that integrates the primary settling tank, I and II contact oxidation tanks, the second settling tank and the sludge tank, and blasts aeration in the I and II contact oxidation tanks to make the contact oxidation The effective combination of the activated sludge method and the activated sludge method has the advantages of both, and overcomes the shortcomings of both, so that the level of sewage treatment can be further improved. There are many sewage treatment processes at home and abroad, which are mainly divided into activated sludge method and biofilm method. Our common aeration method, oxidation ditch method, A / B method, A2 / O method belong to the former, and biological turntable , Contact oxidation belongs to the latter. The integrated ...
