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
Function introduction
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.
Advantages
◆ 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.
Applications
Treatment of domestic sewage, landfill leachate, livestock and poultry breeding wastewater of various scales and other sewage suitable for biochemical process.
