Anaerobic Biological Wastewater Treatment

Anaerobic Biological System
UASB anaerobic sludge bed technology consists of four parts, (1) influent water distribution device; (2) sludge bed; (3) sludge blanket (4) gas-solid liquid separation device, organic wastewater from the bottom into the reaction tank Under anaerobic conditions, organic matter is degraded and metabolized by methane gas and carbon dioxide by anaerobic microorganisms. The waste water, microorganisms and biological gas are collected by the three-phase separator and discharged out of the tank, and the microorganisms are returned to the sedimentation zone. In the reaction tank, the wastewater enters the bottom sludge layer and the middle and upper sludge suspension zone through the distribution pipe, mixes and contacts the microorganisms in the sludge, decomposes the organic matter in the wastewater, converts some organic matter into biogas, and finally the solid-liquid gas The phase separator collects the sludge, the treated wastewater and the biogas.
