Sewage Treatment Annular water tank

Abstract

The invention relates to a sewage treatment annular water tank, the sewage treatment annular water tank comprises a water passing tank arranged on the inner wall of the tank wall of a sedimentation tank, wherein the water passing tank is annular, the height of the tank wall, close to the inner ring, of the water passing tank is lower than the height of the tank wall close to the outer ring. A partition plate is arranged in the middle of the water passing tank, the partition plate divides the water passing tank into a water inlet distribution tank and a water outlet collection tank, the water outlet collection tank is arranged at the inner ring of the water inlet distribution tank, and the height of the partition plate is higher than the height of the tank wall, close to the inner ring, ofthe water passing tank. The inlet water distribution tank is communicated with a water distribution well, and the outlet water collection tank is communicated with a water collection well. The bottomof the water inlet distribution tank is provided with a plurality of water distribution holes. The sewage treatment annular water tank effectively solve the unfavorable factors such as more turnover materials, more potential safety hazards and the like caused by a large number of supporting and maintaining structures such as templates and scaffolds required for pouring a traditional concrete structure, and can avoid the problems of long construction period generated by the 28-day age of the concrete structure, difficulty in guaranteeing the quality of procedures such as pouring and vibrating the concrete thin-wall structure and the like. The water passing tank is arranged at the upper part of the sedimentation tank, and is convenient for operation and maintenance personnel to check and repair.

Description

technical field [0001] The invention belongs to the field of sewage treatment devices, in particular to an annular water tank for sewage treatment. Background technique [0002] With the continuous development of urbanization, the deterioration of environmental pollution has been accelerated. With the introduction of the "Water Ten Measures", all localities have increased the intensity of water area management, and adopted measures such as source control and sewage interception to collect and discharge sewage to sewage treatment plants for treatment. Therefore, my country's water treatment industry is also accelerating the development and research of new technologies according to the development needs of the environment to meet the increasingly severe environmental requirements. In the sewage treatment process, sedimentation is an indispensable link. The sewage can further remove suspended solids in the water through the sedimentation tank. The planar dimensions of sedimen...

AI Technical Summary

Problems solved by technology

[0004] In view of the technical problems existing in the background technology, the sewage treatment annular water tank provided by the present invention can effectively solve the unfavorable factors such as a large number of formwork, scaffolding and other supporting maintenance structures required for pouring of traditional concrete structures, which lead to many turnover materials and many safety hazards. It can avoid the problems of long construction period caused by the 28-day age of the concrete structure and the difficulty in guaranteeing the quality of the pouring and vibration of the concrete thin-walled structure; the water tank is set on the upper part of the sedimentation tank, which is convenient for operation and maintenance personnel to check and repair
