Hydrolysis tank with exhaust and filtering units

Abstract

The invention is applicable to the technical field of sewage treatment, and provides a hydrolysis tank with exhaust and filtering units. The hydrolysis tank comprises a water storage assembly, a filtering assembly, an exhaust assembly and a reaction assembly, wherein the water storage assembly comprises a tank body, a water feeding pipe, a water drainage pipe, an extension pipe, a sludge dischargepipe, valves and a tank cover; the water feeding pipe is fixedly connected with the tank body, and is positioned at the top end of the right side wall of the tank body. Chains, connecting rods and strain bags are arranged and the strain bags are filled with strain sludge so that after a motor is started, the connecting rods and the strain bags can be driven by the chains to move in the moving direction of the chains, and strains in the strain sludge are scattered in sewage through the strain bags, so that pollutants in the sewage are treated, and the problem that a large amount of sludge is deposited at the bottom end of a hydrolysis tank for a long time due to the fact that the strain sludge is directly put into the sewage traditionally is avoided, so that the sludge treatment frequencyis increased, and the sewage treatment effect of the hydrolysis tank is reduced.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a hydrolysis tank with an exhaust filter device. Background technique [0002] The hydrolysis (acidification) treatment method is a method between aerobic and anaerobic treatment methods, and the combination with other processes can reduce treatment costs and improve treatment efficiency. According to the difference in growth rate between methanogenic bacteria and hydrolytic acid-producing bacteria, the hydrolytic acidification process controls the anaerobic treatment in the first and second stages of anaerobic treatment with short reaction time, that is, under the action of a large number of hydrolytic bacteria and acidification bacteria, the insoluble organic matter Hydrolysis into dissolved organic matter, the process of converting difficult-to-biodegradable macromolecular substances into easily biodegradable small-molecular substances, thereby improving the biodegrad...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a hydrolysis tank with an exhaust filter device, which aims to solve the problem that when the current hydrolysis tank is carrying out the sewage treatment process, the bacteria are usually directly placed in the hydrolysis tank, although the bacteria can be more evenly dispersed in the sewage However, since bacteria are generally mixed with a large amount of bacteria culture sludge, long-term direct feeding will lead to the deposition of a large amount of sludge in the hydrolysis tank, which not only increases the treatment frequency of sludge, but also reduces the treatment effect of the hydrolysis tank.
