Abstract

The invention discloses a composite industrial circulating water treatment agent and a preparation method thereof, wherein the composite industrial circulating water treatment agent comprises malic acid, dodecyl trimethyl ammonium chloride, potassium citrate, polyhexamethylene guanidine and water. The preparation method comprises the following steps: (1) mixing quantitative water 35, polyhexamethylene guanidine and dodecyl trimethyl ammonium chloride; (2) heating the solution to 55-65 DEG C, then adding potassium citrate, and carrying out passivation modification on the potassium citrate; and(3) adding malic acid into the solution, and uniformly mixing. According to the invention, the composite industrial circulating water treatment agent does not contain phosphorus, is an environment-friendly circulating water treatment agent, is wide in applicable pH range, and can adapt to various water qualities.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a composite industrial circulating water treatment agent and a preparation method thereof. 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 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 The amount of 80% -90%, therefore, saving circulating cooling water is very necessary. [0003] During the daily operation of industrial circulating water, due to continuous evaporation and concentration...
