Abstract

The invention discloses a baffled MBBR biochemical system of a flexible suspended filler, aiming at solving the problems in the prior art that a suspended carrier is non-uniform in fluidization and is easy to accumulate at an interception net, the biomass of the filler is increased, and dead mud is formed in the filler. The system comprises a tank body, an aeration pipeline, an air blade, a main air supply device and an air stripping reflux device, the tank body is provided with a plurality of groups of baffle walls to be separated into a plurality of groups of baffle chambers, and the plurality of groups of baffle walls are sequentially provided with water outlets with opposite height positions according to the sequence from the water inlet of the tank body to the water outlet of the tank body; the air blade is arranged at water outlets of the multiple groups of baffle walls and jet air flow in the vertical direction; a water outlet intercepting net is arranged at the water outlet of the tank body, and a water inlet intercepting net is arranged at the water inlet of the tank body; an aeration pipeline is arranged at the bottom of the tank body and is connected with a main air supply device; the gas stripping reflux device is communicated with the baffling chamber where the water inlet of the tank body is located and the baffling chamber where the water outlet of the tank body is located to enable liquid to flow back, wherein the particle size of the flexible suspended filler is larger than that of meshes of the intercepting net, so that the flexible suspended filler can flow back along with liquid through the gas stripping reflux device.

Description

Technical field [0001] The present invention relates to the field of sewage biochemical treatment, and more particularly to an MBBR biochemical system for a good oxygen segment. Background technique [0002] The MOVING Biofilm Reactor MBBR process has gradually been widely used in sewage treatment projects in recent years. The process uses the advantages of the active sludge method, but also overcomes the disadvantages of conventional active sludge method and fixed biofilm method. When an aeration is aerated, the rising buoyancy of the air bubble pushes the filler and the surrounding water body flow, and the gas flow is blocked into small bubbles during the raising process. In such a process, the filler is sufficiently stirred and mixed with the water flow, and the air flow is sufficiently divided into fine bubbles, increasing the oxygenation efficiency of biofilm and oxygen and the mass contaminant, and then Improve the ability of the MBBR process. The MBBR process has high volu...
