Environment-friendly water treatment aeration device

Abstract

The invention relates to the technical field of environment-friendly water treatment, and discloses an environment-friendly water treatment aeration device which comprises an aeration tank, a plurality of aeration pipes, a rotating column, a rotating rod and a water outlet pipe, wherein the aeration pipes are distributed at the bottom of the aeration tank at equal intervals, the adjacent aeration pipes are parallel to each other, a plurality of air outlet covers are arranged above the aeration pipes, the bottoms of the air outlet covers are communicated with the interiors of the aeration pipes through air outlet pipes, and a plurality of air holes are formed in the upper surfaces of the air outlet covers, wherein the air holes are communicated with the interior of the air outlet cover. According to the invention, the mesh cylinder driven by the rotating rod to rotate is arranged at the lower part in the aeration tank, after gas acts with sewage to increase the oxygen content, bubbles can be rotationally stirred by the rotating cylinder in the floating process, so that the bubbles can be dispersed while being prevented from being polymerized, and the gas can be smoothly dissolved in the aeration tank. Meanwhile, the uppermost circular plate drives the front shifting plate and the rear shifting plate to stir the sewage, so that the sewage can be further contacted with air to increase the oxygen content, and the aeration effect is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection water treatment, in particular to an environmental protection water treatment aeration device. Background technique [0002] At present, the use of microorganisms to treat sewage has a more environmentally friendly effect. Aeration is a means of making the air and sewage come into strong contact. Its purpose is to dissolve the oxygen in the air into the sewage. There will be many aerobic microorganisms in the activated sludge, and the oxygen incorporated can meet the oxygen requirements of these aerobic microorganisms. These aerobic microorganisms can react and degrade the organic pollutants in the sewage, which can Realize the effect of environmental protection purification of sewage. [0003] In the prior art, when the sewage is aerated, the aeration equipment is generally charged with a large amount of dispersed gas to the bottom of the sewage, and these gases are dissolved in...

Problems solved by technology

[0003] In the prior art, when the sewage is aerated, the aeration equipment is generally charged with a large amount of dispersed gas to the bottom of the sewage, and these gases are dissolved into the water to obtain the effect of aeration. However, in the actual process, the discharge The sewage entering the bottom of the sewage is easy to aggregate into a large bubble under the action of water pressure, which will reduce the amount and speed of gas dissolved in the water, and the aeration effect is not good
