UASB is upflow anaerobic
sludge bed reactor, the whole reactor can separate two parts:
the reaction zone and gap, liquid and solid separate zone.
Sewage upward to the bottom of the anaecobic reactor through
pump, make use of the bottom water distributiong system, sewage
evenly arranged on the whole cross section.While taking
advantage of the water outlet pressure and the role of the gas
production, let wastewater full contact and transfer with
anaecobic sludge, degradation of organic matter in the
wastewater. The wastewater upward slowly at the reactor
zone,further degradation of organic compounds. Gas, water and
sludge rising at the same time, biogas first enter into
three-phase separator exhause through pipe, sludge and sewage
rising to the sepatator zone through the gap of three-phase
separator, sludge precipitate,degradate and reflux to the
bottom of three-phase separator at the separator zone, keep the
biologicald quantity of internal anaecobic recator,
precipitated water discharge the reactor through pipe.
Applications:
High density organic sewage
such as from alcohol honey and limon acid industies.
Middle density such as from
beerm, slaughtering and soft drinking industries.
