Analysis of Organic Compounds Removal in Course of Wastewater Treatment on Refinement Complex Enterprises.

Abstract

There was conducted analysis concerning mechanochemical, biological and sorption treatment of oily wastewater efficiency. There were recognized regularities of transformation and removing organic compounds during different stages of treatment. There was established existence in the content of treated wastewater bio-resistant organic compounds, going in route through all stages of treatment. There was pointed out inhibiting nitrification processes during the biological treatment stage, because of combined effect of two main factors: shortage of easily oxidable organic compounds and existence inhibiting components. Data of conducted gas chromatographic analysis testified, that wastewater, transferred on the mechanochemical treatment stage, distinguished by complex composition, including 179 individual organic matter, at the same time total concentration of organic matter is order 24 mg/l. According to treatment quantity of polluting components decreasing to 2, containing organic impurities 0,05 mg/l (after sorption treatment). There were defined directions of further researches on intensification of wastewater treatment plants for oily wastewater, for the purpose of enterprises’ environmental risks decreasing and achieving effluent quality comply with requirements for discharge into fishery.
