Description

MBR membrane shell structure and MBR membrane group ware

Technical Field

The utility model relates to a sewage treatment technical field, concretely relates to MBR membrane shell structure and MBR membrane group ware.

Background

The Membrane Bioreactor (MBR) technology is a novel sewage treatment and recycling technology which organically combines a Membrane separation technology and a traditional sewage biological treatment technology and greatly strengthens the biological treatment technology, and is also called as a Membrane separation activated sludge method.

Along with the continuous improvement of national living standard, environmental problems are obvious day by day, government departments attach more and more importance to economic growth and the synergistic development of ecological environment, in recent years, new environmental protection methods, ten water and other guidance policies are developed in succession, and a Membrane Bioreactor (MBR) process has the advantages of high pollutant removal efficiency, good effluent quality, direct recycling, high biological concentration, large volume load, land occupation saving, easy realization of automatic control of a system, convenient operation and management and the like, and becomes a core link in a sewage treatment process.

The MBR is mainly characterized in that a membrane group device is provided with a large number of hollow fiber ultrafiltration membranes or flat membranes, the outer diameter of the ultrafiltration membranes is about 2mm generally, the inner diameter of the ultrafiltration membranes is about 1mm, small holes of 0.04-0.1 micron are distributed on the surface of the ultrafiltration membranes, the hollow fiber membrane filaments are like a thin plastic filament when viewed from the outside, and the hollow fiber membranes are vertically and parallelly arranged on the membrane group device. When the membrane filaments are actually used in sewage treatment, outlets at two ends of a plurality of membrane filaments are required to be respectively poured into two rectangular plastic membrane shells by using epoxy resin to form a sealing structure. Namely, the middle part is provided with membrane filaments, the two ends are provided with plastic membrane shells, and the edges of the membrane shells are provided with clear water outlets, thus forming the membrane component. A plurality of membrane modules are arranged on a bracket to form a membrane module device. When the membrane bioreactor runs, the MBR membrane group device is placed in sewage, and the suction pump is connected with the inner hole of the membrane silk through a pipeline. The suction pump is activated and a vacuum is created inside the membrane filaments. The outside sewage pressure of membrane silk is high, and the inside water pressure of membrane silk is low, and under the effect of pressure differential, water permeates the micropore on membrane surface, permeates to inside the hollow fiber membrane silk, flows to the membrane shell at both ends, flows to the clean water basin through the pipeline. The pollutants are blocked to the outside of the surface of the membrane filaments because the diameter of the pollutants is larger than the aperture of the membrane pores, so that solid-liquid separation is realized.

In order to remove pollutants such as sludge adsorbed on the surface of the membrane wire, an aeration device is arranged at the bottom of the membrane module device, unstable gas-liquid two-phase turbulence which flows upwards is generated in the membrane module device under the action of aeration, the membrane wire continuously swings in water flow, air flow and water flow alternately flow over the surface of the membrane wire along the axial direction of the membrane wire, and the pollutants on the surface of the membrane wire are continuously taken away under the scouring of the gas-liquid two-phase flow, so that the surface of the membrane wire is kept clean, the over-current resistance on the surface of the membrane wire is reduced, and the membrane wire continuously pumps water.

In the use process, pollutants such as sludge are easy to gather at the position where the membrane filaments are connected with the membrane shell, the blocking effect of the overall appearance of the membrane shell can slow down the gas-liquid flow speed for flushing the membrane filaments, the density of the position where the membrane is connected with the membrane shell is higher, and the sludge is not easy to flush, so that the membrane filaments at the position where the membrane is connected with the membrane shell are easy to block, and the filtering effect cannot be achieved.
