Embodiment

[0021] Such as figure 1 and 2 Shown, a kind of anaerobic baffle reaction device, comprises reaction pool 3, is positioned at in reaction pool 3 and is separated by dividing plate and baffle to form a plurality of hydrolysis fermentation areas and methanogenic area, hydrolysis fermentation area and methanogenic area Connected in series and allow sewage to flow through one by one, the hydrolysis fermentation zone at the front and the methanogenic zone at the rear are connected to the water inlet pipe 1 and the water outlet pipe 20 respectively, and the water inlet pipe 1 is provided with an inlet pump 2 .

[0022] The anaerobic baffle reaction device described in this embodiment also includes a chemical energy power generation system and a solar heating system. The chemical energy power generation system includes a biogas collector 21 (21-1), a biogas collection pipe 22, a biogas preprocessor 23 and a biogas The generator 24, the biogas collector 21 (21-1) is covered above the ...

Embodiment 2

[0036] This embodiment discloses a method for sewage treatment using the solar heat preservation / chemical energy described in Example 1 to drive the anaerobic folded plate flow reaction device, including the following steps:

[0037] 1. Operation of the reaction pool:

[0038] The incoming water (sewage) enters the reaction tank 3 through the water inlet pipe 2 under the suction of the water inlet pump 1. Under the normal working condition of the agitator 4, the pollutants in the sewage flow up and down along the baffle plate in the reaction tank with the water flow. , in the independent hydrolysis fermentation area and methane production area, it is degraded and metabolized by anaerobic activated sludge, so that the water quality is purified. The MLSS of the anaerobic activated sludge in the reaction tank 3 is 8000mg / L-15000mg / L, and the hydraulic retention time is 12-24h. The purified sewage is discharged through the outlet pipe 20 .

[0039] Second, the power of the react...

Description

technical field [0001] The invention relates to an anaerobic baffle reaction device and a sewage treatment method, specifically, an anaerobic baffle reaction device and a sewage treatment method driven by solar heat preservation and chemical energy, which are used for treating sewage. Background technique [0002] Anaerobic baffle reaction tank, as a new type of high-efficiency anaerobic sewage biotechnology, has been widely used. It uses a series of vertically installed baffles in the reaction tank to divide the reaction tank into several reaction chambers in series, and each reaction chamber can be regarded as a relatively independent upflow sludge bed system. Sewage flows up and down along the baffles in the reaction tank, and passes through the sludge bed of each reaction chamber in turn. The high molecular organic substrates in the wastewater, such as cellulose, starch, protein, etc., are hydrolyzed and fermented (acidified) through contact with microorganisms. In the ...
