Rotary sewage aeration device

Abstract

The invention relates to the technical field of sewage treatment, in particular to a rotary sewage aeration device which comprises a compression pipe, a base, a mounting seat, a piston, a gear motor and an annular stirring blade, the piston is driven by a worm to reciprocate along the compression pipe, so that air and sewage are pressurized and compressed, the dissolved oxygen content of the sewage can be remarkably increased, and the aeration efficiency is improved. In addition, in the aeration process, sewage in the sewage pool forms a flow state from bottom to top and from top to bottom in stages through positive and negative rotation of the annular stirring blades, the sedimentation problem of the sewage pool is avoided, and the sewage treatment device has practical significance and popularization value and is worthy of popularization. It is expected that good economic benefits can be generated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a rotary sewage aeration device. Background technique [0002] Most of the sewage treatment adopts the biological process. The key technology of this process is the aeration of the biological pool, that is, oxygenation; due to the shortage of land resources, the biological pool has developed into a deep ditch type, which requires the aerator to take into account the The stirring action prevents the sludge from settling at the bottom of the deep ditch. [0003] The traditional aerator injects liquid into the air to increase the contact area between the liquid and the air to promote the incorporation of oxygen into the sewage. Although this method can increase the amount of dissolved oxygen, the speed is very slow, which virtually increases the time and cost of sewage treatment. , which is not conducive to the improvement of sewage treatment efficiency, and the flow of li...

Problems solved by technology

[0003] The traditional aerator injects liquid into the air to increase the contact area between the liquid and the air to promote the incorporation of oxygen into the sewage. Although this method can increase the amount of dissolved oxygen, the speed is very slow, which virtually increases the time and cost of sewage treatment. , which is not conducive to the improvement of sewage treatment efficiency, and the flow of liquid is only limited to the surface of the biological pool, it is difficult to achieve the bottom stirring effect required by the deep-water biological pool, and the problem of sludge settlement is prone to occur. If it is based on the existing technology, research and development An aeration equipment with high aeration efficiency and effective avoidance of bottom subsidence will have positive significance for solving the above problems and promoting the development of the industry
