Alcohol plant wastewater treatment equipment

Introduction:
The power driven buried integrated treatment technology for alcohol plant wastewater treatment equipment can be divided into biological contact oxidation method, SBR, A/O and A2/O according to the process. The principle of commonly used A/O treatment technology is that microorganisms in anoxic tanks reduce nitrate nitrogen and nitrite nitrogen in wastewater to gaseous nitrogen and release it, while decomposing difficult to degrade large molecule organic matter into small molecule easily degradable substances, which have the functions of denitrification, hydrolysis, and degradation of some organic matter; In the aerobic tank, most of the organic matter is treated by microorganisms and enters the secondary sedimentation tank for sludge water separation. After disinfection, it is discharged.
The A/O process degrades organic matter while denitrification, greatly reducing oxygen demand, and is an energy-saving biological treatment technology. In order to maintain a high nitrification rate, the reaction residence time is longer than that of ordinary activated sludge process, the sludge settling performance is good, the sludge growth rate is low, the remaining sludge amount is small, and the settling performance is good.
