EFFICIENCY OF USING AN ANAEROBIC BIOREACTOR FOR WASTEWATER TREATMENT

The object of study is the process biogas production in a bioreactor with stirring device and an inert biofilm carrier. problematic issue retention on media at certain number revolutions stirrer. A scheme laboratory setup for studying carrier presented. An important value was determined - specific rate substrate release , without which it impossible to calculate surface determine amount methane released. influence hydraulic flow (Reynolds criterion) formation determined. selected keep prevent its detachment. mass transfer from wastewater biofilm; conversion by active acidogenic biomass into acetic acid; acid methanogenic considered. advantage proposed hydrodynamics anaerobic conditions fluidization, that, due intensive circulation liquid, possible detach media, emphasized. It create optimal apparatus that would fully ensure such technological process. In mode operation bioreactor, n = 2 rpm. final concentration reaches S2 0.1 kg COD/ m3. produced VCH4= 0.409 m3/day. can be used practice treatment following industries: dairies, meat processing plants, juices wines food production. These enterprises have high content organic matter their wastewater. This leads increased produced.
