Kosogina I. Low-waste technology of wastewater treatment by coagulation method

The dissertation is devoted to development low-waste technology of wastewater treatment, polluted by dye andsurfactants, by coagulation method with use of coagulant of sulphate of iron (ІІ). The mechanism of coagulation process isestablished. Formed as a result of treatment of sludge is subject to acid treatment with purpose of regeneration of coagulantfor its further use in recycling and decrease of volumes of wastewater treatment sludge. Regularity of acid dissolution ofwastewater treatment sludge is determined. The opportunity of re-using of the solution obtained after acid dissolutionwastewater treatment sludge, as coagulant for wastewater treatment, polluted by dye and surfactants, is shown. Its shown thatcarrying out of oxidative treatment of solution obtained after dissolution of wastewater treatment sludge is allows to increaseamount of recycling of coagulant
