First, the works
UASB anaerobic reactor sludge reaction zone, gas-liquid-solid three-phase separator (including sedimentation area) and chamber composed of three parts. To deal with the sewage flows from the bottom of the anaerobic sludge bed and sludge in the sludge layer mixed contact, microbial decomposition of organic matter in sewage sludge and put it into biogas. Methane form of tiny air bubbles released, tiny air bubbles in the rising process, merge, gradual formation of larger bubbles. Ministry of sludge bed methane and stir to form a sludge concentration of thin mud mixtures, sludge and water together to rise into the three-phase separator, biogas separation of the lower part of the reflection plate is encountered, folded around to the reflection plate, and then through the water layer into the gas chamber, concentrated in the chamber gas use catheter export, the settling zone of the solid-liquid mixture has been reflected into the three-phase separator, sewage sludge flocculated, the particles gradually increases, and sedimentation under gravity. Precipitation to the inclined wall of the sludge along the inclined wall slip back into the anaerobic reaction zone, reaction zone to the accumulation of large amounts of sludge, treated effluent sludge separated from the top of the overflow weir of the settling zone overflow, and then discharge the UASB tank .
Second, UASB equipment and other anaerobic and aerobic equipment performance comparison table:

Three characteristics:
1, high efficiency, large capacity, energy consumption province, low operating costs;
Small footprint, adaptability, and low cost;
3, large amount of biogas can return to the boiler room, resulting in high economic efficiency.
