Oxygenation type aeration equipment for sewage treatment

Abstract

The invention discloses oxygenation type aeration equipment for sewage treatment. The equipment comprises a fixed block fixedly connected to the side wall of a base; an air suction cavity is formed inthe lower portion of the side wall of the fixed block; the inner wall of the air suction cavity is rotationally connected with a sliding plug cylinder in a sealed mode; an annular groove is formed inthe inner wall of the sliding plug cylinder; a sliding plug is slidably connected to the inner wall of the annular groove in a sealed mode; the lower end of the sliding plug is elastically connectedwith the inner bottom of the air suction cavity through a spring; a lead screw is fixedly connected to the upper end of the sliding plug; and the upper end of the lead screw penetrates through the upper end of the fixed block and is fixedly connected with a wing-shaped plate; and a circular hole is arranged in the upper end of the sliding plug cylinder. The wing-shaped plate slides up and down todrive the permanent magnet to slide up and down, and then induced current is generated on the spiral coil, so that oxygen is generated by water electrolysis at that positive electrode electrolysis rod, and when the screw rod drives the sliding plug to slide up and down, the oxygen at the positive electrode electrolytic rod can be continuously pumped into a sewage pool through the one-way air suction pipe and the one-way air outlet hole, the activity of aerobic bacteria is improved, and the sewage treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an oxygen-enhancing aeration device for sewage treatment. Background technique [0002] With the increasing shortage of water resources, some domestic and industrial water are currently subjected to sewage treatment, that is, the process of purifying the sewage to meet the water quality requirements of being discharged into a certain water body or reused. [0003] At present, most of the sewage treatment is through microbial degradation, and in order to speed up the efficiency of sewage treatment, it is necessary to continuously pump oxygen into the sewage through the aeration system, thereby improving the activity of aerobic bacteria and ensuring the effect of biochemical reactions. Blow air into the sewage tank through the aeration system, resulting in more power consumption and higher cost, and the noise generated when the aeration system is working is relatively larg...

Problems solved by technology

[0003] At present, most of the sewage treatment is through microbial degradation, and in order to speed up the efficiency of sewage treatment, it is necessary to continuously pump oxygen into the sewage through the aeration system, thereby improving the activity of aerobic bacteria and ensuring the effect of biochemical reactions. Blow air into the sewage tank through the aeration system, resulting in more power consumption and higher cost, and the noise generated when the aeration system is working is relatively large, which is likely to cause noise pollution. In addition, the current pumping position in the sewage tank is fixed , so that the oxygen content in the sewage pool is unevenly distributed, and the aerobic bacteria make the degradation efficiency of different places in the sewage pool different, reducing the efficiency of sewage treatment
