A2O (submerged flat membrane MBR) process
Sewage →coarse screen → pump lifting → fine screen → grit settling unit → regulating tank → A2O unit → suction pump → UV disinfection → discharge up to standard (general level A)
◆ Grid slag → pressing → garbage transportation;
◆ Sand settling → sand water separator → garbage transportation;
◆ MBR sludge → dehydration → landfill or incineration
In order to improve and maintain microorganisms concentration (especially those with long generation cycle), stabilize and optimize effluent quality, the microorganism in bioreactor should be intercepted.
◆ Concentration of microorganisms (especially those with long generation cycle) in reactor is high, so area is small, and treatment effect is good and stable;
◆ Aeration can simultaneously supply oxygen for microorganism metabolism and reduce pollution by membrane surface scouring;
◆ Traditional secondary sedimentation tank is replaced by the submerged flat membrane filtration technology, effluent quality is stable and optimized, which is less affected by external factors;
◆ Process is short and easy to manage;
◆ It is convenient to realize automatic control of the process.
Treatment of domestic sewage, landfill leachate, livestock and poultry breeding wastewater of various scales and other sewage suitable for biochemical process.
