It is a new high-efficiency sewage treatment process that combines high-efficiency membrane separation technology with traditional activated sludge method. It uses a membrane module with a unique structure placed in an aeration tank. The water after aerobic aeration and biological treatment is The pump pumps out after filtering through the filter membrane. It is very different from traditional sewage treatment methods and replaces the secondary sedimentation tank and tertiary treatment process in traditional biochemical processes. Because the existence of the membrane greatly improves the solid-liquid separation capability of the system, the water quality and volume load of the system's water output are greatly improved. The water quality standard after membrane treatment is high (exceeding the national first-class standard after disinfection, and finally the water quality and high-quality recycled water with high biological safety, which can be directly used as a source of new water. Due to the filtration effect of the membrane, microorganisms are completely trapped in the membrane bioreactor, achieving complete separation of hydraulic retention time and activated sludge age, eliminating the traditional The problem of sludge expansion in the activated sludge method. The membrane bioreactor has high pollutant removal efficiency and strong nitrification ability, and can perform nitrification, denitrification and denitrification at the same time. The effluent water quality is stable, the remaining sludge output is low, and the equipment is compact and occupies a small area ( Only the traditional process has the advantages of convenient incremental expansion, high degree of automation and simple operation.
Two main features
High-quality and stable treated water quality
Small footprint and no need for sedimentation tank
Remaining sludge Less, low operating cost
Fully automatic control, simple operation and convenient maintenance.
Three application areas
Various industrial organic wastewater similar to sewage, industrial cooling circulating water, etc.
MBR membrane biological treatment equipment
