Integrated sewage treatment device

Abstract

The invention discloses an integrated sewage treatment device. The integrated sewage treatment device comprises an adjusting pool, a contact oxidation pool, a membrane pool and a sludge pool which areconnected in sequence, wherein the contact oxidation pool comprises an anaerobic pool, an anoxic pool and an aerobic pool which are connected in sequence; the anaerobic pool is connected with the adjusting pool; the aerobic pool is connected with the membrane pool; the aerobic pool comprises a pool body, an aerator, an oxygen supply machine, an air injection assembly and a driving mechanism; theair injection assembly comprises a rotating pipe, aeration pipes and oxygen supply pipes; and the driving mechanism is connected with the rotating pipe to drive the rotating pipe to rotate, so the aeration pipes and the oxygen supply pipes swing. The above-mentioned integrated sewage treatment device provided by the invention has the following advantages: the rotating pipe is provided with a plurality of aeration pipes and oxygen supply pipes along an axial direction; the aeration pipes can spray out air; the oxygen supply pipes can spray out oxygen; the driving mechanism can drive the aeration pipes and the oxygen supply pipes to swing; thus, sewage at all depths in the aerobic pool can be in full contact with the air and the oxygen; the oxidation effect of the aerobic pool is guaranteed;and the treatment effect of sewage is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated sewage treatment equipment. Background technique [0002] With the increasingly serious problem of water pollution, more and more attention has been paid to the problem of sewage treatment in many industries, resulting in the emergence of many sewage treatment technologies and sewage treatment devices. Sewage treatment equipment is a kind of industrial equipment that can effectively treat domestic sewage and industrial wastewater in urban areas. It prevents sewage and pollutants from flowing directly into waters, which is of great significance to improving the ecological environment, improving urban quality and promoting economic development. [0003] Existing sewage treatment equipment generally includes sewage tanks, contact oxidation tanks and sedimentation tanks. The contact oxidation tanks can make activated sludge undergo aerobic respiration, decompos...
