Decomposition type treatment type sewage purification treatment device

Abstract

The invention provides a decomposition treatment type sewage purification treatment device, and relates to the field of sewage decomposition treatment devices. The problems that filtering cotton is prone to moisture under the action of high-density water molecules to influence normal gas flow and filtration, an existing device cannot achieve continuous extrusion of water in the filtering cotton while stirring and mixing to improve the decomposition effect, intermittent impact water inflow cannot be achieved during water inflow, and an impact type water inlet mode cannot be used for promoting mixing of sewage in a mixing barrel so as to improve the decomposition efficiency can be solved. The decomposition treatment type sewage purification treatment device comprises a purification box body,and a temporary storage box is welded on the purification box body. Due to the fact that the right end face of an adjusting plate is of an inclined structure, when a filter plate B is stressed to move downwards, the adjusting plate is in a contraction state under extrusion of a rectangular rod, strip-shaped holes and filter holes in the filter plate B are staggered at the moment, and water can beprevented from flowing upwards through the filter holes in the filter plate B when water is drained through the filter plate B.

Description

technical field [0001] The invention belongs to the technical field of sewage decomposition treatment, and more specifically relates to a decomposition treatment type sewage purification treatment device. Background technique [0002] Anaerobic biological treatment of sewage is a method that relies on anaerobic bacteria to degrade and decompose organic matter in sewage to reduce COD and BOD in sewage to discharge standards under the condition of isolating the air. The anaerobic digestion of COD and BOD in sewage is divided into hydrolysis acid production stage and anaerobic fermentation gas production stage. [0003] For example, the application number: CN201310448246.0, the invention discloses a step-by-step decomposition anaerobic pool sewage treatment equipment, including an acidification hydrolysis pool and a strict anaerobic pool, the bottom of the acidification hydrolysis pool is provided with a water distribution pipe, and the acidification hydrolysis pool The water ...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a decomposed treatment type sewage purification treatment device to solve the existing problem that during the filtration process of the overflow gas in the sewage, the filter cotton is easy to cause moisture under the action of high-density water molecules, Thereby affecting the normal circulation and filtration of the gas, and the existing device cannot achieve continuous extrusion of moisture in the filter cotton while stirring and mixing to improve the decomposition effect, and the overall filtering effect is relatively poor; moreover, the above-mentioned application and the existing The device cannot realize intermittent impact water intake during water intake, and cannot use the impact water intake method to promote the mixing of sewage in the mixing tank to improve decomposition efficiency; finally, the above applications and existing devices do not mix while mixing. It can realize the continuous wiping and cleaning of the filter screen, so that the filter screen is easy to clog after a period of use, and the later cleaning is more cumbersome.
