Rapid treatment process for middle-small sewage source, and integrated rapid sewage treatment station thereof

Abstract

The invention discloses a rapid treatment process for small and medium-sized sewage sources. The process flow of the treatment is as follows: sewage, grid pool, balanced gas explosion pool, regulating pool, reaction pool, flocculation pool, coagulation pool, aerobic pool, and anaerobic pool. tank, solid-liquid separation tank, combined filter tower / sedimentation tank, clarification tank. In the integrated rapid sewage treatment station, the above-mentioned pools are integrated, and the pools are connected in sequence. A sludge collection bucket is installed at the bottom of each pool, and a sludge collection bucket is also installed at the bottom of each sludge collection bucket. Mud discharge pipes, each mud discharge pipe is connected and communicated with the sludge thickening tank, and a pump is installed on the mud discharge pipe. Its advantage is that the process flow is short and the sewage treatment speed is fast; the balance pool and the explosion pool in the prior art are combined into one, so that the sewage collection components are more balanced, and the sewage oxidation effect is better; the sewage treatment station adopts multiple combinations, integrated The structure is easy to manage, easy to operate, and occupies a small area, which greatly reduces the cost of building a sewage treatment station.

Description

technical field [0001] The invention relates to the technical field of a sewage treatment process and a sewage treatment station. Background technique [0002] At present, with the continuous improvement of people's living standards, people's requirements for environmental protection are getting higher and higher. Domestic water and industrial water must be strictly treated before they can be discharged. The existing sewage treatment method is: first discharge sewage into In the pool with grille, remove the large pieces of floating matter in the sewage, and then mix all the different sewage into the equalization pool, so that the sewage can be fully mixed in the equalization pool and undergo a series of chemical reactions, and then discharged from the equalization pool The sewage enters the degassing tank, and at the same time, a large amount of air is filled into the degassing tank, so that the sewage in the degassing tank undergoes oxidation reaction, and the sewage discha...

AI Technical Summary

Problems solved by technology

This current sewage treatment method has the following disadvantages: 1. After the above-mentioned sewage treatment system has been working for a period of time, it will be in the balance pool, the explosion pool, the physical and chemical pool, the aerobic pool, the anaerobic pool, and the sedimentation pool. There will be a large amount of sludge deposited at the bottom of the tank, so the whole sewage treatment system has to be stopped, and the sludge in each tank will be removed manually or by machine, which will not only reduce the efficiency of sewage treatment, but also increase Reduced the cost of sewage treatment; 2. When the above sewage treatment system is working, each pool uses artificial operations to achieve mutual cooperation, making it difficult for the treatment effect to meet the national discharge requirements

There are also some deficiencies in the sewage treatment stations currently used to treat sewage. The existing sewage treatment stations are to establish each sewage treatment unit independently, and then use pipelines to connect each sewage treatment unit to perform sewage treatment. When working, it is not easy to manage and operate, and the construction of such a sewage treatment station occupies a relatively large area, which will increase the construction cost of the sewage treatment station. Now the structure of each sewage treatment tank is not reasonable enough, so that the final treatment of sewage Various indicators are difficult to meet
