FIELD: equipment for deep biological purification of domestic sewage water by means of suspended active silt, used in individual cottages and houses, as well as in hotel complexes, schools, sportive clubs, villages and public catering enterprises.
SUBSTANCE: method involves feeding sewage water into equalizing reservoir containing active silt, working water level sensor and maximum water level sensor; pumping out crude water from tubular filter of equalizing reservoir and directing it therefrom into settler, and from settler into chamber containing porous filter; pumping silt into silt stabilization chamber; feeding air into reservoirs and chambers; ceasing operation of apparatus and withdrawing completely purified water. Apparatus operates in two-phase mode of operation.
EFFECT: provision for producing high-quality sewage water fit for utilization in agriculture, reduced consumption of power, intensified purification process, enhanced reliability in operation of apparatus, reduced labor intensity for manufacture and operation of apparatus.
