Аннотация: The authors have studied the possibility of improving the quality of purification of highly concentrated oil-emulsion wastewaters by treatment with polyethylenimine (PEI), with final purification in sorption filters. The following factors influencing purification of oil-emulsion wastes were chosen: x//1, the initial concentration oПоказать полностьюf emulsified oil products (mg/liter); x//2, the PEI dose (mg/liter); x//3, the temperature ( degree C); x//4, the settling time (h); the response function was y, the content of oil products in the purified water (mg/liter). A linear regression equation for y was derived from the experimental data. Analysis of this equation shows that the temperature of the treated wastewaters and the initial concentration of emulsified oil products have the greatest influence on the purification effect during treatment with polyethylenimine. It is shown that by using polyethylenimine for purification of highly concentrated oil-emulsion wastewaters followed by final filtration through sorbent filters the purification effect can be raised to 99. 5%, which gives a filtrate satisfying the quality requirements for recycled water supply.
