Aeration tank for sewage treatment with height adjustable function

Abstract

The invention discloses an aeration tank for sewage treatment with a height adjustable function. The aeration tank comprises a tank body, two mounting bases are fixedly connected to the side walls of the tank body in a symmetrical mode, height adjusting devices are fixedly connected to the mounting bases, fixing rods are fixedly connected to the inner sides of the height adjusting devices, and vertical supporting plates are fixedly connected to the other ends of the fixing rods; the vertical supporting plates are located in the tank body, first bearings and second bearings are arranged on the vertical supporting plates in an embedded mode from bottom to top, and first rotating rods and second rotating rods are fixedly connected to the inner rings of the first bearings and the second bearings. The aeration tank has the advantages that adjustment of the angles of aeration heads is achieved by means of transmission of a bevel gear, so that the aeration heads are changed from vertical positions to horizontal positions; during aeration, the cross section of the tank body can be covered with the aeration heads, so that the aeration effect is effectively improved, and the effect of sewage treatment is improved. The aeration tank has the advantages of being rational in structural design, convenient to use and good in aeration effect, and has certain application and popularization value.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an aeration tank for sewage treatment with a height-adjustable function. Background technique [0002] Sewage treatment (wastewater treatment): The process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] In daily life, a variety of domestic sewage will be produced, and domestic sewage needs to be treated before it can be discharged. One of the processes in the sewage treatment process is aeration, so that the activated sludge in the sewage can get enough dissolved oxygen and then decompose the harmful substances in the sewage...

AI Technical Summary

Problems solved by technology

One of the processes in the sewage treatment process is aeration, so that the activated sludge in the sewage can get enough dissolved oxygen and then decompose the harmful substances in the sewage. This process requires stirring to make the activated sludge evenly dispersed in the sewage. However, The aeration effect of the existing aerator is poor, and it is difficult to fully mix the air sent by the aerator with the activated sludge, and the aeration angle is generally set upward, and the angle cannot be adjusted. Therefore, The sewage treatment effect is also poor
