MBR membrane biological treatment of sewage treatment equipment in wastewater recycling aspects, has the following characteristics: (1) energy efficient solid-liquid separation, the loss of suspended substances in wastewater, colloidal substances, biological unit of microflora separated from the purified water. Separation process is simple, small footprint, good water quality is generally not subject to tertiary treatment and reuse. (2) allows the biological treatment unit biomass is maintained at a high concentration, so that the volume load is greatly improved, while the membrane separation efficiency, so that the processing unit of hydraulic retention time is greatly shortened, a corresponding reduction in the footprint of the bioreactor. (3) Due to prevent the loss of various microflora, help slow the growth of bacteria growth (nitrification bacteria, etc.), so that a variety of metabolic processes in the system smoothly. (4) to make some macromolecular refractory organics longer residence time, in favor of their decomposition. [5] As with other membrane technology filtration separation technology in the long-term operation, the film as a kind of filter media clogging the membrane by water running time gradually decreased effective backwashing and chemical cleaning can reduce the flux the effective life of the decline, maintain MBR systems. (6) MBR technology in wastewater treatment, because the process is simple, easy to operate, can achieve automatic operation and management.
