3000tpd Sewage Treatment System, MBR Membrane, River/Hospital/Rural
MBR sewage treatment is a common method of modern sewage treatment. It adopts membrane bioreactor (Membrane Bioreactor, referred to as MBR) technology, which is a new technology that combines biological treatment technology and membrane separation technology, which replaces the two in the traditional process. Sedimentation tank, which can efficiently separate solid and liquid to obtain stable reclaimed water for direct use. It can also maintain a high concentration of microbial biomass in the biological tank, with less residual sludge in the process, and extremely effective removal of ammonia nitrogen, effluent suspended solids and turbidity Close to zero, the bacteria and viruses in the effluent are greatly removed, the energy consumption is low, and the area is small. In the 1970s, membrane bioreactors have been used for sewage and wastewater treatment in the United States, Japan, South Africa and many European countries. Work. The water source is taken from domestic sewage (such as shower drainage, toilet drainage, laundry drainage, kitchen drainage, toilet drainage, etc.) and cooling water.
Process flow:
Raw water → grille → regulating tank → lifting pump → bioreactor → circulating pump → membrane module → disinfection device → reclaimed water storage tank → reclaimed water water system
Process characteristics
Membrane biological treatment technology is applied to wastewater recycling and has the following characteristics:
(1)Solid-liquid separation can be carried out efficiently, and the suspended matter, colloidal matter, and microbial flora lost by the biological unit in the wastewater can be separated from the purified water. The separation process is simple, occupies a small area, and the effluent quality is good. Generally, it can be reused without tertiary treatment.
(2)The biomass in the biological treatment unit can be maintained at a high concentration, which greatly increases the volume load. At the same time, the high efficiency of membrane separation greatly shortens the hydraulic residence time of the treatment unit and reduces the area of the bioreactor accordingly.
(3)Because it can prevent the loss of various microbial flora, it is conducive to the growth of slow-growing bacteria (nitrifying bacteria, etc.), so that various metabolic processes in the system can proceed smoothly.
(4)Make the residence time of some macromolecules difficult to degrade organics longer, which is beneficial to their decomposition.
(5)Membrane treatment technology is the same as other filtration and separation technologies. In the long-term operation process, the membrane is blocked as a filter medium, and the water flow rate of the membrane gradually decreases during the operation time. Effective backwashing and chemical cleaning can slow down the membrane flux. The decline in the MBR system maintains the effective service life of the MBR system.
(6)MBR technology is applied in urban sewage treatment. Because of its simple process and convenient operation, it can realize fully automatic operation and management.
Scope of application
Residential districts, office buildings, shopping malls, hotels, restaurants, offices, schools, troops, factories and other domestic sewage and similar industrial organic wastewater, such as textile, beer, paper, leather, food, chemical and other industries
