AI Technical Summary
Traditional Bio-Rayk processes suffer from problems such as uneven aeration, poor denitrification efficiency, significant impact from low temperatures, high difficulty in modification, and difficulty in fixing mechanical equipment, resulting in unstable wastewater treatment effects and insufficient treatment capacity.
The traditional Bio-Rad tank was transformed into a multi-functional AAO biological tank by introducing a low-oxygen biological multiplication process, adding a multi-functional zone and a low-oxygen zone, using perforated tube stirring equipment and micropore oxygenation aeration, combined with an online dissolved oxygen meter and blower automatic control system, eliminating underwater mechanical power equipment, and using inclined tube sedimentation to replace MBR.
It has doubled the sewage treatment capacity and efficiency, solved the problems of fixation and denitrification in the transformation of traditional effluent treatment tanks, reduced the demand for mechanical equipment and operating costs, and ensured that the effluent meets the standards stably.
