FIELD: process engineering.SUBSTANCE: invention may be used for biological cleaning of industrial effluents. Upward flow reactor (1) comprises tank (2), pipelines (31-34), distributor (3) of effluents, flotation separators (10, 20) of reactor (7) water, biomass (8) and biogas (9), collector (4), gas separator (6) for separation of biomass (8) and biogas (90). First flotation separator (10) comprises one or several caps (11) for gas with discharge holes connected with collector (4). Note here that cross-section area of discharge holes (13) is adjusted by movable shields (14). Reactor comprises actuators to drive said movable shields (14, 24). Note also that actuators are equipped with, preferably, hydraulic drives. Mind that reactor (1) incorporates an electronic control. At least one edge area (13) in discharge holes is limited by flexible shell shield connected with fluid pump.EFFECT: higher efficiency of biological cleaning.19 cl, 5 dwg |
