Abstract

The invention belongs to the technical field of sewage treatment and particularly discloses an industrial circulating water treatment agent. The industrial circulating water treatment agent comprises,by mass, 0.5-2 parts of a surfactant, 20-35 parts of a compound corrosion inhibitor, 12-25 parts of a scale inhibitor, 1-8 parts of a bactericide and 30-60 parts of water. The compound corrosion inhibitor comprises imidazoline, oxalyl hydrazide, sodium erythorbate and a zinc salt. The circulating water treatment agent can be used in the water treatment process to realize better scale inhibition,sustained release and sterilization effects, and does not produce phosphorus pollution.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an industrial circulating water treatment agent. Background technique [0002] With the continuous development of the national economy, water resources become more and more tense, and water conservation has become an important part of the national policy of environmental protection. Domestic urban industrial water accounts for about 80% of the total urban water consumption, while the consumption of industrial circulating cooling water accounts for about 2 / 3 of industrial water consumption. The proportion of circulating cooling water consumption in the petroleum and petrochemical industry is even larger, accounting for about 80%-90% of water consumption, so saving circulating cooling water is very necessary. [0003] During the daily operation of the circulating cooling water, due to continuous evaporation, the salts in the water are concentrated, and the contact between...
