Description

MBR membrane process integration sewage treatment device

Technical Field

The utility model relates to a sewage treatment device technical field specifically is MBR membrane technology integration sewage treatment device.

Background

In the field of water pollution treatment, the existing main processes mainly comprise various variation processes of AO, AAO, oxidation ditch, MBR, MBBR, SBR and SBR. The MBBR technology increases the biomass and the biological species in the reactor by adding a certain amount of suspension carriers (MBBR fillers) into the reactor, thereby increasing the treatment efficiency of the reactor. 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 carrier in water makes air bubbles finer, and the utilization rate of oxygen is increased. In addition, each carrier has different biological species inside and outside, anaerobic bacteria or facultative bacteria grow inside, aerobic bacteria grow outside, each carrier is a micro-reactor, and nitrification reaction and denitrification reaction exist at the same time, so that the treatment effect is improved. MBR replaces the terminal secondary sedimentation tank of the traditional biological treatment technology with a membrane module, keeps high active sludge concentration in a bioreactor, and improves the biological treatment organic load, thereby reducing the occupied area of sewage treatment facilities and reducing the amount of excess sludge by keeping low sludge load. Mainly utilizes the membrane separation equipment immersed in the aerobic biological tank to trap the activated sludge and macromolecular organic matters in the tank. The membrane bioreactor can retain microorganisms with longer generation period due to effective interception, can realize deep purification of sewage, simultaneously nitrifying bacteria can be fully propagated in the system, has obvious nitrification effect, and provides possibility for deep phosphorus and nitrogen removal.

When using, the existing MBR membrane for sewage treatment usually filters sewage as the first-level filtering equipment, because impurities in sewage are more, when using the MBR membrane as the first-level filtering equipment, more impurities in sewage easily cause a quick blocking effect to the MBR membrane, particles in sewage cannot be effectively filtered, the filtering effect of the MBR membrane is reduced, and meanwhile, the service life of the MBR membrane is shortened.
