Description
MBR wastewater treatment is a common way of modern wastewater treatment, which uses membrane bioreactor technology is a new technology that combines biological treatment technology and membrane separation technology, replacing the traditional process of secondary sedimentation tank, it can efficiently carry out solid-liquid separation, and get direct use of stable medium water. It can also maintain a high concentration of microorganisms in the biological tank, with little residual sludge, extremely effective removal of ammonia and nitrogen, near-zero suspended matter and turbidity in the effluent, significant removal of bacteria and viruses in the effluent, low energy consumption and small footprint.

Membrane biological treatment technology applied to the recycling of wastewater has several characteristics.
(1) It can efficiently carry out solid-liquid separation, separating suspended substances, colloidal substances and microbial flora lost from biological units in wastewater from the purified water. The separation process is simple, occupies a small area and the effluent quality is good, and can generally be reused without tertiary treatment.
(2) The biomass in the biological treatment unit can be maintained at a high concentration, so that the volumetric load is greatly increased, while the high efficiency of membrane separation makes the hydraulic retention time of the treatment unit greatly shortened, and the floor space of the biological reactor is correspondingly reduced.
(3) As the loss of various microbial flora can be prevented, it is conducive to the growth of slow-growing bacteria (nitrifying bacteria, etc.), thus enabling various metabolic processes in the system to proceed smoothly.
(4) The residence time of some large molecules of hard-to-degrade organic matter becomes longer, which is conducive to their decomposition.
(5) membrane treatment technology and other filtration and separation technology, as in the long-term operation process, the membrane as a filter media clogging, membrane through the water running time and gradually decline effective backwashing and chemical cleaning can slow the decline in membrane flux, maintaining the effective life of the MBR system.
(6) MBR technology is used in municipal wastewater treatment, due to its simple process, easy to operate and can achieve fully automatic operation and management.
