Sewage filtration purification series

MBR is a highly effective membrane separation technology and the traditional activated sludge method of new type high efficiency sewage filtration purification technology, it has a unique structure of the submerged membrane module put in aeration tank, sewage filtering purification series after aerobic aeration and biological treatment of water, the pump out after by membrane filtration. It has big difference with the traditional sewage treatment methods, replaced the traditional biochemical process in the pond, and tertiary treatment process, as a result of the existence of membrane system can be greatly improved the ability of solid-liquid separation, so that the effluent water quality and volume load have been greatly improved, with different process, effluent can reach the standard landscape water or mixed with water. Due to the effect of filtering of the membrane, microorganism was completely trapped in the bioreactor, hydraulic retention time and sludge age thoroughly separation, active sludge to eliminate the problem of sludge bulking in traditional activated sludge process. Membrane bioreactor is characterized by a high on pollutants removal efficiency, nitrification ability is strong, can be simultaneous nitrification, denitrification, and denitrification effect is good, stable discharging water, excess sludge production is low, the equipment is compact, simple operation, etc. Currently sewage filtration purification series are widely used in sewage and various biochemical effluent discharges of industrial wastewater treatment and reuse.
