Anaerobic Treatment System

Anaerobic Biological System (degradation inflow COD15000 or more)
UASB treatment tank is an advanced anaerobic wastewater treatment equipment, which is mainly composed of four parts, namely (1) influent water distribution device (2) sludge bed (3) sludge blanket (4) gas-solid liquid three-phase separator The sludge bed is sludge particles deposited at the bottom of the treatment tank, and the sludge blanket is a mixture of suspended sludge in the sludge bed and the gas generated by the anaerobic reaction, and the wastewater entering the treatment tank is in the sludge bed and The sludge blanket area is decomposed by anaerobic gas, and the generated gas and the suspended sludge with it float in the three-phase separator, the gas is collected and discharged outside the tank, and the suspended sludge is precipitated in the relatively stable water flow and returned. In the treatment tank, the treated water is discharged outside the tank and enters the subsequent unit for processing, which has three advantages:

1. High volumetric efficiency, the required volume of the treatment tank is small, saving investment costs.
2. High efficiency and small footprint
3. Low sludge production, no oxygen supply, low energy consumption, wide application range of wastewater, high load tolerance for water quality changes.
