Abstract

The invention provides an integrated domestic sewage treatment device, relates to the technical field of sewage treatment equipment. In the prior art, the sludge concentration of a traditional sewagetreatment process is difficult to further improve, and the synchronous nitrogen and phosphorus removal effect is limited. The invention just aims to solve the above technical problems. The device comprises a shell; an anoxic tank unit, an anaerobic tank unit, an aerobic tank unit, a secondary sedimentation tank unit, a safety filter tank unit and an equipment room are sequentially arranged in theshell; the anoxic tank unit is arranged on the front side of the anaerobic tank unit and communicated with the anaerobic tank unit; the anaerobic tank unit is arranged on the front side of the aerobictank unit and is communicated with the aerobic tank unit; the secondary sedimentation tank unit is arranged in the aerobic tank unit and is communicated with the aerobic tank unit; the safety filterunit is arranged on the rear side of the aerobic tank unit and is communicated with the secondary sedimentation tank unit; and the equipment room is arranged at the tail end of the safety filter unit.According to the sewage treatment device, the contradiction of a traditional sludge method is alleviated, the sludge concentration of a mixture is high, the nitrogen and phosphorus removal effect isimproved, and it is guaranteed that effluent reaches the standard.

Description

Technical field[0001]The present invention relates to the technical field of sewage treatment equipment, in particular to an integrated domestic sewage treatment device.Background technique[0002]At present, in the field of sewage treatment, the traditional AAO process (anaerobic-anoxia-aerobic process) is a commonly used sewage treatment process, which can be used for secondary sewage treatment or tertiary sewage treatment and reuse of reclaimed water. The effect of nitrogen and phosphorus removal. The traditional AAO process (anaerobic-anoxic-aerobic method) is widely used in the field of water treatment. The process flow is simple, and the three environments of anaerobic, anoxic and aerobic are alternately operated, which can simultaneously remove organic matter, nitrogen and phosphorus . After the sewage treatment using the AAO process passes through the aerobic tank, the sewage mixture enters the secondary settling tank. After the solid-liquid separation, the supernatant overflo...
