A kind of expanded granular sludge bed reactor EGSB organic sewage treatment device

Technical field

The utility model relates to technical field of sewage, specially a kind of expanded granular sludge bed reactor EGSB is organic Sewage-treatment plant.

Background technique

EGSB third generation anaerobic reactor is improved from second generation UASB anaerobic reactor, existing UASB reactor occupied area It is bigger, and treating capacity is relatively fewer, UASB reactor is divided into three areas, i.e. water distribution area, reaction zone and three-phase separate from bottom to top From area, UASB reactor waste water is by the bottom as uniform as possible for introducing reactor, and sewage ramps up, into reaction zone, anaerobism The process contacted in waste water and mud granule occurs for reaction, forms the good granule sludge of settling property or cotton-shaped dirt in reactor It can produce biogas in mud, organic sewage and mud granule or floc sludge contact process, the rising sewage of additional UASB itself adds The speed circulation of inside reactor, rises to the three-phase separation area at top, completes the three phase separation of gas-liquid-solid, UASB is without sludge Refluxing unit, also without equipment is mixed, the water inlet for relying primarily on the biogas and low side of itself generation makes Sludge Bed top Sludge is in suspended state, and USAB reactor easily causes blocking, and, USAB reactor more sensitive with load variations to water quality In the higher waste water of processing solid suspension concentration, the problems such as being easy to appear short stream, block, the sludge of USAB inside reactor Layer is the bed that is relatively fixed, so water distribution is uneven, mass transfer effect is poor, and the initial start-up used time is longer, is existed to sewage treatment Limitation, reduces working efficiency, is not able to satisfy and uses needs.
