Patent ID: 7919000

Claim:
A reactor ( 10 ) for the anaerobic treatment of waste water comprising a reactor tank ( 12 ), at least one inflow line ( 42 , 42 ′) arranged in the lower region ( 14 ) of the reactor tank ( 12 ) for the supply of waste water to be treated into the reactor ( 10 ), at least one inflow distributor ( 20 ) for the mixing of the waste water supplied to the reactor ( 10 ) with the medium located in the reactor ( 10 ), at least one overflow ( 30 , 30 ′) arranged at the upper region of the reactor tank ( 12 ) for the draining off of treated water as well as at least one separator ( 24 , 26 ), characterized in that the inflow distributor ( 20 ) comprises at least one deflection means ( 22 , 22 ′, 22 ″), with the at least one deflection means ( 22 , 22 ′ 22 ″) being designed such that waste water emerging from the at least one inflow line ( 42 , 42 ′) is deflected into a circular, upwardly directed flow, viewed from the reactor cross-section, and with 1 to 80% of the reactor cross-section being filled by the at least one deflection means ( 22 , 22 ′, 22 ″).
