Arrangement of Crude Bottom's Acidification and Assessment of it Efficiency on Nitrification Intensification, De phosphotation under Waste waters Treatment

Abstract

There was proposed usage of acidification method (prefermentation) of crude bottom at primary settler for removing from it easily oxidable organic substances, improving of activated sludge's oxidizing properties and increasing of denitrification efficiency, de phosphotation in the process of biological treatment at operating wastewater treatment facilities, designed for petroleum refinery's wastewater treatment together with municipal waste waters. There was demonstrated positive impact of acidogenesis products on increasing efficiency of denitrification and de phosphotation's processes without use of additive anoxic and anaerobic zones at existing biological treatment facilities.
