Oxidizing tank

Abstract

An oxidizing tank comprises a vertical cylindrical tank body and a stirrer reducer fixed at the top of the tank body through a seat, wherein the bottom of the tank body is mounted on a skirt, the bottom end of the skirt is reliably connected with a ground embedded screw, the top of the tank body is sealed by a sealing cover plate, a stirring shaft in the tank body is connected with the stirrer reducer through a coupler, multiple groups of staggered paddles are arranged on the stirring shaft, an exhaust port and an overflow port are formed in the upper part of the tank body, a manhole, an air inlet and a sewage inlet are formed in the bottom of the tank body, an air distribution pipe is arranged at the bottom inside the tank body, a circle of effluent weir groove is formed at the overflow port in the tank body, and strip-shaped flow blocking plates are arranged on the inner wall of the tank body, distributed around the circle center of the tank body in an arrayed manner, provided with a plurality of connecting pieces from top to bottom and fixedly connected with the inner wall of the tank body. The oxidizing tank is simple in structure, convenient to maintain, uniform in oxidization and high in efficiency.

Description

Technical field [0001] The invention relates to a sewage treatment equipment, in particular an oxidation tank. Background technique [0002] As the country's requirements for environmental protection become more and more stringent, high-salt wastewater treatment technology is becoming a trend in the development of wastewater treatment technology. [0003] However, in the traditional high-salt wastewater treatment process, the slurry is oxidized outside the tower. The slurry is stored in an oxidation tank. After the top of the tank is opened, air is introduced to oxidize the slurry in the tank. This oxidation method fails to adequately oxidize the sewage, because of its uneven oxidation, resulting in low oxidation efficiency and high energy consumption. Summary of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides an oxidation tank with high oxidation efficiency, energy saving and low consumption, and simple structure. [0005] In order...

Problems solved by technology

[0003] However, in the traditional high-salt sewage treatment process, the slurry is oxidized outside the tower, and the slurry is stored in the oxidation tank. After the tank top is opened, air is introduced to oxidize the slurry in the tank.

This oxidation method fails to fully oxidize the sewage, because of its uneven oxidation, resulting in low oxidation efficiency and high energy consumption
