Laboratory studies of wastewater treatment in hybrid reactors with moving bed are presented. The biomass in reactors exists as a suspend - activated sludge - and as an attached - biological biofilm. Laboratory research on 3 parallel reactors in continuous - flow ad batch system was realized. Reactors were periodically aerated. As moving carriers for biomass cylindrical PE elements were used. Domestic sewage after preliminary treatment in septic tank was treated. The study revealed, that the suspended biomass in systems has decreased and the attached biomass has increased with an increase in organic loading. Likewise contents of suspended solids in the treated sewage has increased. Biomass growth was higher in batch system and was independent of technological parameters of the process
