Problems solved by technology

[0003] The existing acid-base neutralization device for sewage treatment generally injects sewage directly into the pH adjustment pool through the sewage pipeline, and directly injects the medicine into the pH adjustment pool through the medicine pipe, so that the medicine and sewage are acid-base neutralized. Second, use the aeration device to promote the rate of the chemical reaction. The existing aeration device generally uses the aeration tube to directly pass the gas into the pH adjustment tank. In this process, the contact area between the gas and the aqueous solution is limited. As a result, the overall speed-up effect is not good, so corresponding improvements are made for this problem

Abstract

The invention belongs to the technical field of sewage treatment, particularly relates to an acid-base neutralization device for sewage treatment, and provides the following scheme aiming at the problem of poor aeration acceleration effect of an existing device: the acid-base neutralization device comprises an adjusting tank, a connecting port is formed in the bottom of the adjusting tank in a penetrating manner, and an aeration pipe is in threaded connection with the top of the connecting port; a plurality of horizontal sections and a plurality of vertical sections are connected with rotatingrings in a nested mode, the outer walls of the circumferences of the rotating rings are communicated with a plurality of exhaust pipes, a plurality of first vent holes and a plurality of second ventholes are formed in the two sides of the contact positions of the aeration pipe and the rotating rings respectively, and fine third vent holes are formed in the exhaust pipes. According to the invention, the aeration pipe comprises a structure that the horizontal sections and the vertical sections are connected in sequence, the rotating rings are arranged on the aeration pipe, and the exhaust pipes and the rotating rings rotate under the action of air pressure difference due to different hole diameters of the first vent holes and the second vent holes, so that the contact area of gas and a solution is greatly increased; therefore, the catalytic effect of the aeration device is effectively improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an acid-base neutralization device for sewage treatment. Background technique [0002] In recent years, the country has attached great importance to the discharge of industrial sewage. In the treatment of sewage, after the treatment of heavy metals such as lead and nickel and other organic pollutants, the waste water is often acidic or alkaline. If it is discharged directly, it will cause water pollution. Therefore, It is also necessary to carry out terminal acid-base neutralization treatment; alkaline wastewater needs to be neutralized with acid, and acidic wastewater needs to be neutralized with alkali. Generally, urban drainage pipes have clear regulations on the pH value of discharged industrial wastewater. That is to say, according to the national regulations on wastewater discharge standards, the pH value of the terminal water quality after electroplating wastewate...
