The MBR containerized sewage treatment plant produced by our company, also known as membrane bioreactor, is a new type of sewage treatment process that combines membrane separation technology with traditional activated sludge method. The system combines the advantages of biological treatment engineering and membrane separation engineering, and is widely used in advanced sewage treatment due to its superior effluent quality compared to other conventional processes.
Working Principle
The sewage first flows or is pumped into the grid tank, and after passing through the grid to remove large suspended solids, it prepares conditions for the normal operation of subsequent treatment units; Afterwards, it flows into the regulating tank to stabilize the water volume, regulate the water quality, and then flows into the hydrolysis and acidification treatment unit. Under the action of hydrolysis bacteria, insoluble organic matter is hydrolyzed into soluble substances. Under the synergistic action of acid producing bacteria, large molecular substances and difficult to degrade substances are transformed into small molecular substances that are easy to biodegrade, improving the biodegradability of wastewater. When the influent pH is neutral or slightly alkaline, the effluent pH can be stabilized at a neutral state. At the same time, apart from the improvement and reflux of sewage, there is basically no other power consumption, so it is only about 1/5 to 1/10 of the power consumption of aerobic treatment. This allows sewage to be treated in subsequent aerobic tanks with lower energy consumption and shorter retention time, thereby improving the treatment efficiency of sewage and reducing sludge generation. The effluent from the hydrolysis and acidification treatment unit flows into the biological contact oxidation treatment unit, and most of the organic matter is removed under the action of aerobic microorganisms. The effluent flows into the sedimentation zone, where flocculants are added. Small particles coagulate and bond into larger particles, which are removed in the form of sediment under the action of gravity. The supernatant overflows to the disinfection zone, and after disinfection, it flows into the reclaimed water reuse tank to meet the standard for reuse.
