In recent years the increasing importance has the problem of environment protection, and first of all water objects, from pollution. For sewage treat-ment, concentrated on the organic pollution the most acceptable is biological method of cleaning on two-phasic anaerobic and aerobic technology. The stage of anaerobic processing is carried out in the bioreactors working with biomass deduction. In the study the comparison of overall performance of bio-reactors of two types was carried out: the anaerobic biofilter and the combined (hybrid) reactor. In the reactor the anaerobic flooded biofilter sewage was pumped through ground distributive system, was distilledthrough a layer of loading material and tak-en away from the top part of the reactor. Cut poly-ethylene shaving was used as loading. In the bio-reactor of the combined type heaped loading mate-rial from polyethylene rings was used which was placed in the top part of the bioreactor on the sup-porting lattice. In the lower part of the bioreactor the layer of anaerobic silt was formed. Researches were conducted on the model drains prepared on the milk of Krasnoyarsk city dairy plant. For start-up of installations into the work the dumped deposit of primary settlers of right-bank treatment facilities of Krasnoyarsk was used. In the conditioned water defined pH, the flying fatty acids (FFA), the per-manganat oxidability (PO), nitrogen of ammoni- um salts, phosphorus of phosphates. The conducted researches allowed drawing a conclusion that from two studied types of bioreac-tors the reactor of the combined type as pH the conditioned water conforms to requirements to wa-ter supply of an aerobic stage while water after the reactor of the first type needs to be alkalinized.
