Abstract

The invention provides a moving bed bio-membrane reactor based on blade self-driven rotary aeration. The moving bed bio-membrane reactor comprises a reactor body, a bearing support is arranged at the upper end of the reactor body, an air riser is arranged on the bearing support, an air inlet pipe is arranged at the upper end of the air riser, the lower end of the air riser is fixed on a plummer block II, and the plummer block II is arranged at the bottom of the reactor body. Rotary blades are further arranged on the air riser, a rotary air transverse pipe is arranged at the lower end of the air riser, and a through hole is formed in the rotary air transverse pipe. The reactor provided by the invention can promote uniform fluidization of a filler, prevent the phenomena of filler accumulation or ball death and the like, and also can prevent sludge sedimentation.

Description

technical field [0001] The invention relates to the technical field of sewage biological treatment, in particular to a moving bed biofilm reactor based on blade self-driven rotary aeration. Background technique [0002] The fluidization of the packing in the moving bed biofilm reactor is a key link. The aeration tank of the sewage treatment plant (station) using the MBBR process often has local packing accumulation caused by the uneven distribution of the air in the whole tank, which affects the treatment effect. . The reason for this problem is that the aeration of the moving bed biofilm reactor often uses perforated tube aeration, the perforated tube in the aeration tank is fixedly installed, the distance between the parallel perforated tubes, the installation level of the perforated tube is not enough and the aeration system Uneven aeration on the plane caused by pipeline installation blockage and other reasons. In order to solve this problem, it is usually to increase ...
