Multistage AO-MBBR (anaerobic-moving bed biofilm reactor) technological sewage treatment device with adjustable stage number and treatment method

Abstract

The invention discloses a multistage AO-MBBR (anaerobic-moving bed biofilm reactor) technological sewage treatment device with an adjustable stage number and a treatment method implemented by the aidof the multistage AO-MBBR technological sewage treatment device, and belongs to the technical field of sewage treatment. The multistage AO-MBBR technological sewage treatment device comprises a firstbiochemical reaction basin, a second biochemical reaction basin, a sedimentation basin, a phosphorus removal filter basin and a water inlet main pipe. A first insertion groove, a second insertion groove, a third insertion groove and a fourth insertion groove are formed in an inner basin wall of the first biochemical reaction basin; a fifth insertion groove, a sixth insertion groove, a seventh insertion groove and an eighth insertion groove are formed in a basin wall of the second biochemical reaction basin, and the first biochemical reaction basin is communicated with the second biochemical reaction basin; the sedimentation basin is communicated with the second biochemical reaction basin, a water via net is arranged at a communicated position of the sedimentation basin and the second biochemical reaction basin, a sludge sedimentation hopper and a sludge discharge pipe are arranged in the sedimentation basin, the sludge discharge pipe is arranged at the bottom of the sludge sedimentation hopper, and the sedimentation basin is further communicated with the phosphorus removal filter basin. The multistage AO-MBBR technological sewage treatment device and the treatment method have the advantages that multistage AO systems which are serially connected with one another are formed, the locations of insertion plates can be adjusted, accordingly, the multistage AO-MBBR technological sewage treatment device and the treatment method are high in adaptability to domestic sewage with different levels of pollution load, effluent treatment procedures are pertinent, and sewage treatment effects can be guaranteed.

Description

technical field [0001] The invention relates to a multi-stage AO-MBBR process sewage treatment device with adjustable series and a treatment method using the treatment device, belonging to the technical field of sewage treatment. Background technique [0002] In recent years, with the vigorous construction of rural domestic sewage treatment facilities in the country, the problem of rural residents' domestic sewage polluting the surrounding water environment has also been effectively improved. However, due to the relatively scattered residents in rural areas and the large economic differences between regions Furthermore, the water quality of domestic sewage in different rural areas and different villages in the same area has certain differences, even significant differences, especially in economically developed rural areas, COD Cr At 150-700mg / L, TN at 20-100mg / L, or even higher values; and the current construction mode of rural sewage treatment facilities is the simultaneous...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an adjustable multi-stage AO-MBBR process sewage treatment device and a treatment method using the treatment device, which solves the problem that the existing sewage treatment equipment cannot be adjusted and adapts to changes. Insufficient, the actual influent load does not match the design influent load, which leads to the problems of high energy consumption and low efficiency.
