Aerobic tank with uniform aeration and large reaction area

Abstract

The invention discloses an aerobic tank with uniform aeration and large reaction area. The aerobic tank comprises a tank body, the bottom of the tank body is provided with a mixing zone, an aerobic zone is arranged above the mixing zone, a gas-liquid separation zone is arranged above the aerobic zone, the aerobic zone is internally provided with an aeration pipe, a filling layer is disposed above the aeration pipe, the height of the aerobic zone is 2-3m, an aeration mesh plate is arranged on the aeration pipe, the aeration mesh plate is connected to the aeration pipe through a cross bar, both ends of the filling layer are provided with a rotating member, and the rotating members are fixedly connected to the tank body. The arrangement of the aeration meshes enables uniform aeration, the sewage treatment effect is better, and the filling layer can rotate, thus increasing the reaction contact area, and improving the sewage treatment efficiency.

Description

technical field [0001] The invention relates to the field of industrial machinery, in particular to an aerobic pool with uniform aeration and large reaction area. Background technique [0002] With the development of social production, social division of labor is becoming more and more refined, environmental problems are becoming more and more prominent, especially the situation of water pollution is becoming more and more severe, sewage treatment has become an important issue nowadays, and the participation of aerobic pools is indispensable in the process of sewage treatment. The application number is CN94207548 .X discloses a fully enclosed multifunctional high-efficiency aerobic pool, consisting of a filter chamber (34), upper and lower A2 anoxic layers (14, 15), an O aerobic chamber (12), and an A1 anaerobic layer (27) five cavities, the rectangle of the multi-bacteria bed that three-layer net plate (13) forms, or the mobile multi-layer pond structure that can be carried...

AI Technical Summary

Problems solved by technology

The aerobic tank is provided with an oxygen supply device (10) that can provide an oxygen-enriched ecological environment. The present invention can discharge sewage at a high speed and volatilize harmful gases rapidly, and provides key equipment with simple structure and excellent performance for the sewage purification system. However, this aerobic There is no aeration tube plate in the tank, the mixing effect is not good, the mixing efficiency is low, the packing layer cannot be rotated, the reaction contact area is small, and the sewage treatment efficiency is not high
