With the purpose of provision of necessary mass exchange it is developed new constructions of anaerobic and aerobic bioreactors with fibrous carriers for microorganisms immobilization. Constructive peculiarity of anaerobic bioreactor is the mixing system with using of pump, recirculated pipe and perforated pipe which is placed along of the central line of bioreactor. Developed constructions aerobic bioreactors lineament is along of central line of cylindrical plant placing of perforated piping for provision of air and intensive mass transfer between wastewater and immobilization hydrobionts on carriers and creating suspended condition for loosely swimming particles of activated sludge. It is proposed the model for calculation of laminar flow parameters for this constructions.

Developed mathematical model give a possibility to estimate the constructive elements of bioreactors such as plant dimension, perforated piping diameter and linear, perforation dimension at project works, reconstruction and building of wastewater stations on anaerobic-aerobic technology with immobilized microorganisms biocenos on the fibrous carriers.  

Key words: wastewater, biological treatment, bioreactor.
