MBR diaphragm

): BR technology is a new wastewater treatment technology that is an organic combination of membrane separation technology and biotechnology
br): It uses membrane separation components to intercept activated sludge and macromolecular organic matter in the biochemical reaction tank, eliminating the need for a secondary sedimentation tank. Therefore, the concentration of activated sludge
br ): can be greatly improved, and the hydraulic retention time (R) and sludge retention time (R) can be controlled separately
br ): while the refractory substances are reacted Continuously reacts and degrades in the device. Therefore, the membrane bioreactor process has greatly enhanced the function of the bioreactor through membrane separation technology.
br ) :
br ) : Advantages of membrane bioreactor in optimizing biochemical effects:
br ) : High removal rate of pollutants, strong ability to resist sludge expansion, and good effluent quality Stable and reliable, there is no suspended matter in the effluent
br ): The membrane bioreactor realizes the complete separation of the reactor sludge age R and the hydraulic retention time R, greatly simplifying the design and operation
br): Membrane machinery The interception effect avoids the loss of microorganisms, and a high sludge concentration can be maintained in the bioreactor, thereby increasing the volume load and reducing the sludge load. The BR process omits the secondary sedimentation tank, greatly reducing the floor space
br ) : Because R is very long, the bioreactor also plays the role of a sludge nitrification tank, thereby significantly reducing sludge production, low remaining sludge production, and low sludge treatment costs
br ) : Due to the interception of the membrane The effect lengthens R, creating a microorganism that is conducive to slow proliferation. Such as the environment where nitrifying bacteria grow, which can improve the nitrification capacity of the system, and at the same time help improve the treatment efficiency of refractory macromolecular organic matter and promote its complete decomposition
br ): BR The activated sludge in the aeration tank is not affected by the production of During operation, the activated sludge will change due to changes in the concentration of incoming organic matter and reach a dynamic balance, which makes the system water stable and resistant to shock loads
br ): larger The hydraulic circulation results in uniform mixing of sewage, thus making the activated sludge well dispersed and greatly increasing the specific surface area of the activated sludge. The high dispersion of activated sludge in the BR system is another reason for improving the effectiveness of water treatment. This is incomparable to the larger bacterial gel clusters formed by ordinary biochemical water treatment technology
br ): Membrane bioreactors are easy to integrate, easy to realize automatic control, and easy to operate and manage.
