Abstract

FIELD: oil-refining, petrochemical and other industries. SUBSTANCE: before sewage purification beginning surface active substances and iron chloride (III) are fed into sewage in amount of 3 - 7 mg/l and 1-3 mg/l correspondingly. "Flokaton 200-40" or "KF-91" are used as surface active substances. EFFECT: method allows to increase degree of sewage purification from excessive active sludge (water clarification degree increased) and to decrease residual concentration of petroleum products in purified water.

Изобретение относится к области обработки промышленных сточных и оборотных вод, содержащих избыточный активный ил и нефтепродукты после стадии биологической очистки, и может найти применение в нефтеперерабатывающей и нефтехимической промышленности, а также на других предприятиях, где возможно попадание нефтепродуктов в сточные воды. Способ очистки сточной воды, содержащей избыточный активный ил и нефтепродукты, отстоем. Перед началом очистки в нее подают ПАВ и хлорид железа(lll) в количестве 3-7 мг/л и 1-3 мг/л соответственно. В качестве ПАВ используют "Флокатон 200-40" или КФ-91", Использование изобретения позволяет повысить степень очистки сточной воды от избыточного активного ила (повысить степень осветления воды) на 0,7% (с 97,5 до 98,2%) и снизить остаточное содержание нефтепродуктов в воде на 16,4 мг/л (с 19,0 до 2,6 мг/л).The invention relates to the field of treatment of industrial wastewater and recycled water containing excess activated sludge and oil products after the biological treatment stage, and may find application in the oil refining and petrochemical industries, as well as in other enterprises where oil products may enter the wastewater. The method of purification of wastewater containing excess activated sludge and oil products, sludge. Before cleaning, surfactants and iron chloride (lll) are fed into it in an amount of 3-7 mg / l and 1-3 mg / l, respectively. As a surfactant, use "Flocaton 200-40" or KF-91 ". Using the invention allows to increase the degree of wastewater treatment from excess activated sludge (increase the degree of clarification of water) by 0.7% (from 97.5 to 98.2%) and reduce the residual oil content in water by 16.4 mg / l (from 19.0 to 2.6 mg / l).
