Improvement of Treatment Technology of Industrial Wastewater of the Kudryashovsky Piggery Complex of the Novosibirsk Region
Summary
Features of collection, disposal and treatment of industrial wastewater of the Kudryashovsky piggery complex (the Novosibirsk Region) are considered. The main reasons for improper operation of the local sewerage treatment facilities are revealed. The basic reason for a halt of facilities is a generation of solid deposits presented by bibasic salt of magnesium-ammonium orthophosphate (МgNH4PO4•6H2O). on their surface. Salt crystals consolidate on reinforced concrete structures, fittings, and equipment. Results of the study aimed at the improvement of technology of industrial wastewater treatment using flocculants at the stage of mechanical treatment are presented.
