摘要：
FIELD: technological processes.SUBSTANCE: invention relates to the biofilm nitrification-contact denitrification system and method, in which environmentally acceptable technology is used, as well as water recovery technologies, and which provide the organic carbon, nitrogen and phosphorus thorough removal from wastewater. Biofilm nitrification-contact denitrification system (I) includes at least one wastewater receiver (II), through which the untreated sewage is supplied into the system, at least one selector tank (III), in which found in the sewage the precipitated organic matter mixes with the biomass, at least one intermediate clarifier (IV), in which solid organic substances are precipitated by means of bioflocculation, at least one biofilm aero tank (V), in which the nitrification process is carried out, at least one deoxygenation chamber (VI), which allows to reduce the dissolved oxygen high concentration that occurs in the biofilm aero tank (V), at least one contact denitrification reservoir (VII), in
