Abstract

The invention relates to the technical field of sewage treatment, and discloses a corridor-type aeration tank. They are respectively connected to the front and rear ends of the horizontal screen. The horizontal screen is separated from the bottom wall of the pool body. Both sides of the screen at the inlet end and the screen at the outlet end are connected to the left and right side walls of the pool body. The screen mesh, the screen mesh at the inlet end, the mesh mesh at the outlet end and the left and right side walls of the pool body are enclosed to form a packing cavity with suspended fillers. The bottom wall of the pool body is evenly distributed with aeration discs. A first perforated pipe network is provided, and a second perforated pipe network is provided on the rear side of the screen mesh at the outlet end; the liquid inlet end of the return device is arranged at the rear end of the packing cavity, and the liquid outlet end of the return device is arranged at the front end of the packing cavity; By adopting the invention, the utilization rate of oxygen can be improved, the water treatment effect and treatment capacity can be strengthened, and the blockage caused by the fluidized suspended filler can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a corridor-type aeration tank. Background technique [0002] With the development of society and economy, the effluent discharge standards of domestic sewage treatment plants have been continuously improved. The sewage treatment plants need to be upgraded and improved to increase the corresponding treatment facilities to meet the new standards. Cost is too high. Therefore, in the existing aeration tank, the suspended filler is added to form the MBBR mud film composite process. By increasing the microbial biomass and microbial population, the biochemical treatment effect of the aeration tank is improved, and the collision and shearing effect of the suspended filler in the water make the air The bubbles are finer, increasing the utilization of oxygen. In addition, each carrier has different biological species inside and outside, some anaerobic bacteria or facultative bac...
