Abstract

The invention provides an aeration system of a biochemical sewage treatment tank. A plurality of first aeration pipes distributed on the surface of a rotary drum can aerate sewage in a tank body, andsewage nozzles can introduce air in the rotary drum into a mixing chamber from an air inlet pipe; the mixing chamber has sewage entering from a diffusing pipe; the sewage is in full contact with the air, and the mixed water and air is sprayed out from the diffusing pipe to increase the oxygen content of the sewage and provide sufficient oxygen for the microorganisms in a tank body, thereby improving the sewage aeration treatment efficiency; moreover, the multiple first aeration pipes are arranged to achieve an effect from multiple aspects, and the sewage treatment efficiency is improved; furthermore, a first lifting device and a second lifting device can drive the rotary drum to move up and down along a rail, so that the aeration system provided by the invention can aerate the sewage in the whole tank body and improve the aeration efficiency and the biochemical reaction rate of sludge. Therefore, the sewage treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to an aeration system for a biochemical sewage treatment pool. Background technique [0002] The random discharge of sewage will have a great negative impact on the environment. At present, people often use aeration tanks to treat sewage. The aeration tank is a structure that uses activated sludge method for sewage treatment. The system and the water inlet and outlet are composed of three parts. The pool body is generally built with reinforced concrete, and its planar shape is rectangular, square and circular; aeration is a means to make air and water come into strong contact, and its purpose is to dissolve oxygen in the air in water. The aeration structure of the aeration device is single, and the mixing of sewage and air is not sufficient, resulting in low aeration efficiency, and it is difficult to meet people's growing sewage treatment needs. Contents of the invention [0003...
