Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0037] Figure 1~5 A sewage treatment system is shown, including grid tank 1, primary sedimentation tank 2, regulating tank 3, anaerobic tank 4, aerobic tank 5 and secondary sedimentation tank 6 connected in sequence, wherein,

[0038] The lower part of the grid pool 1 is provided with a first liquid inlet, which communicates with the sewage source, and the lower part of the grid pool 1 is provided with a first liquid outlet relative to the first liquid inlet. There is a grid in the pool 1, which forms an inverted V-shaped structure by connecting the upper parts of the first plate body 11 and the second plate body 12. The first plate body 11 is horizontally provided with at least three elongated first The opening 111, the second plate body 12 is vertically provided with at l...

Abstract

The invention discloses a sewage treatment system, which includes a grid pool, a primary sedimentation pool, an adjustment pool, an anaerobic pool, an aerobic pool and a secondary sedimentation pool that are communicated in order. Specifically, the grid pool is internally provided with grids, and the upper parts of a first plate body and a second plate body are connected to form an inverted V shaped structure. The primary sedimentation pool is internally provided with a filter plate, which is formed by a third plate body, a fourth plate body and a fifth plate body that are in head-tail connection from top to bottom and are provided with mesh through-holes. The adjustment pool is in an inverted cone structure, and is internally provided with a spiral drainage groove. The anaerobic pool is internally provided with composite probiotic groups. The aerobic pool is supplied with oxygen by an aerator and is internally provided with filler. The secondary sedimentation pool is internally equipped with a plurality of vertical baffle plates, the free ends are in staggered arrangement, and gaps exist between adjacent vertical baffle plates. The sewage treatment system provided by the invention can effectively remove organic matters and suspended solids in sewage, reduce the energy consumption of aeration, and save the sewage treatment cost and manpower cost. Being stable, the system has good sewage treatment effect, and has promotion value.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a sewage treatment system. Background technique [0002] In modern society, domestic sewage and industrial wastewater are discharged into sewers or natural lakes without treatment, causing serious water pollution. With the growth of the national economy and the enhancement of public awareness of environmental protection, sewage treatment has received public attention. At present, domestic sewage treatment methods include indoor hair, chemical methods and biological methods, mainly including chemical adsorption, chemical precipitation, density separation, chemical oxidation, chemical reduction, ion exchange, and membrane dialysis. When the COD is 2000-4000mg / L, the COD removal rate of physical and chemical methods can reach 50-87%. But there are also problems: high equipment cost, unstable sewage system, and the sewage purification rate needs to be further improved, which is not s...
