Abstract
The paper presents laboratory and experimental studies on the purification of surface water sources from oil contamination by sorption material on the basis of production waste. Energy waste is a slurry of chemical water treatment, which is formed during liming and coagulation at the stage of preliminary purification of natural water. Based on the sludge, the hydrophobic sorption material “MGSM” was developed. The following requirements are imposed on the sorption materials that allow, at low costs, the most effective cleaning of the water surface from petroleum products: hydrophobicity, oil capacity, buoyancy, ease of utilization from the water surface, efficient work in a different temperature range, resistance to water disruption, non-toxicity, optimal price. The material obtained has these requirements. The technical characteristics of the developed sorption material were determined: oil capacity, wetting contact angle, an express analysis of the quality of the aqueous extract of the hydrophobic sorbent developed for the acute lethal toxicity of fish of the Poecilliareticulata Pet. and crustaceans Daphniamagna Str. A technological scheme for utilization of oil-contaminated hydrophobic sorption material as a secondary energy resource in industrial enterprises is proposed, a calculation of the volume of air and combustion products during its combustion, calculation of harmful emissions, thermal calculation, and prevented environmental damage.
