METHOD OF EFFLUENTS BIOLOGICAL TREATMENT Russian patent published in 2013 - IPC C02F3/02 C02F3/20 C02F103/20 

FIELD: process engineering.

SUBSTANCE: invention may be used for treatment of domestic waters or similar effluents brought about by one or several residential or similar structures remote from drainage systems including treatment of effluents of cottages, settlements, camping sites, tourist centers, roadside cafes and motels In compliance with proposed method, effluents are fed into aeration chamber 8 with guide tube 9 whereto air is forced via diffuser 11 of aerator 10. Settled active silt is remove by vertical 7 for pumping exceed active silt while cleaned water is discharged by gravity via discharge pipe of annular spillway. Aeration chamber 8 has solid bottom 12 while diffuser 11 of aerator 10 is arranged there nearby. Guide tube 9 is shaped to inverse cone with respect to aeration chamber bottom. Guide tube lower end is located under solid bottom 12. Cleaned water and active slit discharge openings 3 are arranged above guide tube end in aeration chamber conical part. For pre-separation of solid inclusions from fine fractions, separator with polymer bed is used. Before discharge into sil, cleaned water is additionally cleaned at said-gravel filter.

EFFECT: simplified process, higher quality of treatment.
