Problems solved by technology

[0002] Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid. The purpose is to obtain enough dissolved oxygen to enable microorganisms to oxidize and decompose organic matter in sewage under the condition of sufficient dissolved oxygen. General sewage treatment Usually, the method of sandblasting liquid into the air is used. This method has poor oxygen dissolution effect and slow biological reaction in sewage. In addition, ordinary aeration equipment only has one aeration device, and usually only aeration discs are used for aeration. , although this method can increase the oxygen solubility, but the speed is very slow, which greatly increases the time and cost

Abstract

The invention discloses a multistage aeration device for sewage treatment. The device comprises a main machine body, a sewage chamber is arranged in the main machine body, the left side surface of themain machine body is provided with an induction box, an induction chamber is arranged in the induction box, a connecting tube and a three-way tube are communicated between the induction chamber and the sewage chamber, the connecting tube is located at the upper side of the three-way tube, the leftward extension part of the three-way tube is communicated with an external sewage source, an electromagnetic valve for controlling the three-way tube to communicate with or seal the sewage source is fixedly mounted outside the three-way tube, and a stirring mechanism capable of stirring the sewage toprevent particles from settling is arranged in the sewage chamber. The device can greatly increase the oxygen content of the sewage by two aeration processes, so the microbial reaction in the sewageis sufficient, and the sewage can be purified quickly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multi-stage aeration device for sewage treatment. Background technique [0002] Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid. The purpose is to obtain enough dissolved oxygen to enable microorganisms to oxidize and decompose organic matter in sewage under the condition of sufficient dissolved oxygen. General sewage treatment The way of sandblasting liquid into the air is usually used, which has poor oxygen dissolution effect and slow biological reaction in sewage. In addition, ordinary aeration equipment only has one kind of aeration device, usually only aeration disc is used for aeration , although this method can increase the oxygen solubility, but the speed is very slow, which greatly increases the time and cost. Contents of the invention [0003] The object of the present invention is to provide a multi-stage aerati...
