Self-reflux oxidation pond and self-reflux method thereof

Abstract

The invention discloses a self-reflux oxidation pond and a self-reflux method thereof. The self-reflux oxidation pond comprises an oxidation pond body, a walkway frame is fixedly installed on the upper surface of the oxidation pond body, vertical partition plates which are vertically distributed are evenly and fixedly installed on the lower surface of the walkway frame, and the interior of the oxidation pond body is evenly divided into four independent cabins along the vertical partition plates. Arc-shaped plates are fixedly installed at the middle position of each independent cabin. Each independent cabin is provided with a first biological bin, a second biological bin and a third biological bin along the arc-shaped plates. Each arc-shaped plate is vertically distributed. The middle position of the walkway frame is cylindrical, and the cylindrical interior of the walkway frame is provided with an inner cavity. A servo motor is fixedly installed at the bottom end of the interior of the inner cavity, and a driving gear is fixedly installed at the output end of the servo motor. In the using process, a sewage self-reflux effect is achieved, so that the biodegradation efficiency of the sewage can be improved, and the using process is simple and direct.

Description

Technical field [0001] The present invention relates to the field of sewage treatment, and more particularly to a self-return oxidation tank and a self-return method thereof. Background technique [0002] The bio-carousel is replaced with a rotating plate instead of the fixed filter material. When working, the turntable is immersed or partially immersed in the contact reaction tank filled with sewage, and under the drive of the drive. The rotating shaft is driven together with a certain line speed. . The turntable is alternately in contact with the sewage and air. After a period of rotation, a layer of biofilm will be attached to the disc. When transferring into the sewage, the organic contaminants in the biofilm adsorbed the sewage, absorb the dissolved oxygen in the biofilm film, decompose the organic matter, and the microorganism is propagated in this process; the turntable transferred Contact with air, the air is constantly dissolving into the water film, increasing its disso...

Problems solved by technology

In this process, in addition to the transfer of organic matter (BOD, COD) and O2, there are other substances, such as CO2, NH3, etc., between the biofilm attached to the turntable and the sewage and air, forming a continuous process. The processes of adsorption, oxidative decomposition, and oxygen absorption make the sewage continuously purified. It is one of the most widely used methods in sewage treatment at present. However, in the process of use, only one kind of biological colony can be placed in each oxidation pool. In a separate oxidation pond, the biodegradation efficiency decreases, the input cost increases, and the sewage treatment efficiency is not high. Therefore, in order to solve such problems, we propose a self-reflux oxidation pond and its self-reflux method
