Problems solved by technology

Large-scale sewage treatment plants generally adopt CASS, oxidation ditch and other processes with denitrification and phosphorus removal functions, all of which have facultative / anaerobic tanks and aerobic reaction tanks, but small-scale sewage treatment generally adopts aerobic processes without nitrogen and phosphorus removal If the process with denitrification and phosphorus removal is adopted, it will have the disadvantages of large floor area and high manufacturing cost, and it is set up separately from the filtration equipment, which increases the investment in equipment and infrastructure
Traditional sludge bed filtration generally adopts a columnar structure, and there is a dead zone in the separation of sludge and water, so the efficiency needs to be improved

Embodiment Construction

[0006] The integrated biochemical filtration sewage treatment equipment proposed by the present invention comprises a treatment pool 1, the entrance of which the sewage enters the treatment pool is 12, a V-shaped sludge bed filter 5 is set in the treatment pool, and the inside thereof is a mud-water separation zone 4, V-shaped The sludge bed filter 5 separates the treatment tank into a concurrent / anaerobic zone 2 and an aerobic reaction zone 3. There is a certain gap between the bottom of the V-shaped sludge bed filter and the bottom of the treatment tank, and the bottom of the sludge bed filter A sludge bed water inlet 6 is provided on the side close to the aerobic zone, and a sludge return pipe 7 is provided at the bottom of the sludge bed filter. The sludge return pipe is connected to a return pump 8, and the sludge returns to the top of the facultative / anaerobic zone An aeration device 11 is provided at the bottom of the aerobic zone, and an outlet overflow device 9 is inst...

Abstract

The invention discloses an integrated biochemical filtering sewage treatment apparatus, belonging to the field of sewage treatment. The integrated biochemical filtering sewage treatment apparatus comprises a treating pool and a V-shaped sludge bed filter in the treating pool, wherein the V-shaped sludge bed filter divides the treating pool into a facultative / anaerobic area and an aerobic reaction area. The integrated biochemical filtering sewage treatment apparatus is suitable for the fields of municipal sewage, domestic sewage, industrial sewage and the like, which not only can be applied to large-scale sewage centralized treatment, but also is applicable to small-scale disperse sewage treatment such as rural areas, residential areas, tourist attractions and the like.

Description

technical field [0001] The invention relates to an integrated biochemical filtration sewage treatment equipment, specifically a kind of biological treatment of nitrogen and phosphorus removal and sludge bed filtration integrated, that is, a facultative / anaerobic pool, an aerobic reaction pool and a sewage The sewage treatment equipment integrated with mud filter bed is suitable for municipal sewage, domestic sewage, industrial sewage and other fields. It can not only be used for centralized treatment of large-scale sewage, but also suitable for small-scale decentralized sewage treatment, such as rural areas, residential areas, tourist attractions, etc. Background technique [0002] With the increasingly stringent sewage discharge standards, not only high organic matter removal efficiency is required, but also high nitrogen and phosphorus removal effects are required. Nitrogen and phosphorus removal is a major problem in the field of sewage treatment. If the effect is not good...
