Multistage municipal sewage biological purification integrated device

Abstract

The invention relates to a multistage municipal sewage biological purification integrated device. The device comprises a pool body; a water inlet, a water outlet, a cleaning port, a microbe feeding port, and a viewing port are disposed on the pool body; a mixed biofilm formation clapboard is disposed in the pool body; the clapboard partitions the pool body into three chambers; the three chamber comprise a deposition separation pool, a biological reaction pool, and an SBR treatment pool which are connected orderly. An axial grating is disposed in the middle of the deposition separation pool, and partitions the pool into an upper layer and a lower layer; stereo elastic fillers are disposed at the lower layer. Microbe fillers are disposed in the biological reaction pool. The SBR treatment pool is provided with an aeration system and stereo elastic fillers. the aeration system is automatically controlled and operated through a PLC device. The device of the invention is high in treatment efficiency, good in discharged water quality, automatic in device operation, convenient for maintenance, and suitable for popularization and application.

Description

Technical field [0001] The invention relates to a sewage biological purification device, in particular to a multi-stage urban sewage biological purification integrated device. Background technique [0002] Protecting the ecological environment and realizing the strategy of sustainable development are the themes of social development today. To achieve sustainable development of the real estate industry, not only must the intensive use of natural resources, but also requires the ecologicalization of housing products and their production and use process. At present, the domestic sewage in the common community is generally discharged directly into the municipal pipe network along with the sewage pipe, or the sewage is initially treated by the three-compartment septic tank technology, and then discharged into the municipal pipe network. The direct discharge increases the work of the follow-up sewage treatment plant, while the three-format septic tank requires a large amount of c...

AI Technical Summary

Problems solved by technology

The direct discharge will increase the work of the follow-up sewage treatment plant, while the three-format septic tank has a large amount of construction, a large area, high cost, a long construction period, and inconvenient management and operation.
