Problems solved by technology

[0005] 3. During the operation, the membrane is easily polluted, and the membrane flux drops rapidly. This is because of the deposition of particles on the membrane surface, bacteria and macromolecules on the membrane surface are all adsorbed or enter the membrane material, or membrane hole clogging
If it is not cleaned and maintained in time, it will cause a decrease in water prod

Abstract

A new water treating group technology with a high purifying function. The invention disposes the waste water by a sequencing batch active sludge technics, a sequencing batch composite biofilm technics, a composite film separating technics or a combined sequencing batch composite biofilm technics and composite film separating technics to meet the requirement and output the water; contemporary, washing the ultramicro filter membrane core of sequencing batch composite biofilm technics and composite film separating technics and other filter membrane cores by washing technics online. The invention can enlarge the microbe inhabit in clean water and progenitive areas, strengthen the contacting of the biofilm and waste water with a low operation cost and has an orderly continuity, a cyclical cycle, a progressive pushing flow and can effectively meet the discharge requirement after the waste water disposal.

Description

[0001] Technical field: the present invention belongs to the technical field of sewage treatment technology. Background technique: [0002] Membrane-bioreactor process technology, that is, MBR process, is a new type of wastewater treatment technology that combines membrane separation technology and biotechnology. It uses membrane separation equipment to intercept the activated sludge and macromolecular organic matter in the biochemical reaction tank. Therefore, the concentration is greatly increased, the hydraulic retention time and the sludge retention time can be controlled separately, and the secondary settling tank is omitted, and then the activated sludge in the reactor biodegrades the organic matter in the sewage and the refractory substances can be in the reaction tank. Continuous reaction and degradation, the degraded water is filtered out through the membrane device so that the water quality can reach the standard for reuse or discharge. Therefore, the membrane-biorea...
