MBBR integration sewage treatment device

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to MBBR integrated sewage treatment equipment.

Background

The MBBR (moving Bed Biofilm reactor) sewage treatment device increases the biomass and the biological species in the sewage treatment device by adding a certain amount of suspension carriers into the sewage treatment device, thereby improving the treatment efficiency of the sewage treatment device. As the density of the filler is close to that of water, the filler is completely mixed with the water during aeration, and the environment for the growth of microorganisms is three phases of gas, liquid and solid. The collision and shearing action of the suspension carrier in water makes air bubbles finer, and the utilization rate of oxygen is increased.

The biomass of the suspended carrier biomembrane of the MBBR technology can grow in a pool together with the biomass of the activated sludge in a biochemical pool of the traditional activated sludge technology to form an MBBR biomembrane and activated sludge mixed MBBR sludge membrane aerobic pool, and sewage can be treated more efficiently. The suspended carrier intercepting screen required by the effluent of the MBBR mud film aerobic tank is also one of the most important facilities of the MBBR mud film aerobic tank, and the hydraulic load of the screen overflow directly determines the size and the manufacturing cost of the overflow area of the effluent screen.
