An MBR Membrane-bioreactor (MBR) is a new type of wastewater treatment system that combines Membrane separation technology and biological treatment technology. The membrane component replaces a secondary sedimentation tank at the tail end of the traditional biological treatment technology, the concentration of the high-activity sludge is kept in a bioreactor, the organic load of biological treatment is improved, the occupied area of a sewage treatment facility is reduced, and the excess sludge amount is reduced by keeping low sludge load. Mainly utilizes the membrane separation equipment immersed in the aerobic biological tank to trap the activated sludge and macromolecular organic matters in the tank. The concentration of activated sludge (MLSS) in the membrane bioreactor system can be increased to 8000-10000mg/L, even higher; the sludge age (SRT) can be prolonged to more than 30 days.
The membrane bioreactor can retain microorganisms with longer generation period due to effective interception, can realize deep purification of sewage, simultaneously nitrifying bacteria can be fully propagated in the system, has obvious nitrification effect, and provides possibility for deep phosphorus and nitrogen removal.
(7) Disinfection + reuse water tank: the effluent is further sterilized and disinfected by sodium hypochlorite and enters a reuse water tank.
The solid-liquid separation device can effectively carry out solid-liquid separation on the garbage of the washing and sweeping vehicle, increase solid-liquid treatment equipment and reduce occupied area for adjustment according to on-site conditions, reduce the space occupied by solid-liquid mixed liquid in the garbage storage tank, greatly improve the garbage collection amount and reduce the garbage transferring and transporting cost; the sewage is subjected to sewage treatment and standard discharge or reuse treatment of washing and sweeping vehicles, watering lorries and the like on site, the device has a simple structure, and the garbage solid-liquid separation treatment efficiency is high, and the operation and the maintenance are easy; the garbage treatment method based on the device effectively provides a transfer point of the washing and sweeping vehicle, greatly improves the working efficiency and the operation cost of the washing and sweeping vehicle, and responds to the national energy-saving and emission-reduction policy.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the present invention, and these modifications should be construed as the protection scope of the present invention without inventive effort.
