Abstract

A process for treating the circulated cooling water containing oil features that the oil-stripping disperser, corrosion and scaling inhibitor, and microbe-growing nutrients containing carbon source and nitrogen source and added to said cooling water.

Description

technical field [0001] The invention relates to a treatment method for circulating cooling water, in particular to a treatment method for circulating cooling water containing leaked oil. Background technique [0002] Usually, when oil leakage occurs in the circulating water system of a large chemical enterprise, the method of extensive drainage and supplementation is adopted, that is, the slime stripping agent is first added, after stripping, a large amount of water is drained, and then corrosion and scale inhibitors are added, but this method is difficult to remove the sludge. Grease attached to the cooling system. [0003] Chinese patent application CN1193609A discloses a cleaning pre-membrane agent used in a circulating water system for cleaning dirt such as microbial scale in the system. It is composed of conventional water quality stabilizer composed of corrosion agent and dispersant, and the inorganic salt complex agent is composed of silicate, manganate, carbonate an...
