Abstract

The invention belongs to the field of water treatment, and particularly relates to a preparation method of an environment-friendly compound scale inhibitor. According to the method, enrichment cultureis performed on a strain capable of generating organic acid in humus soil, thereby obtaining a beneficial strain; in addition, in a culture process, an additive is used as a mutagen, calcite is usedas a mutation guide agent, then the strain is mutated to the direction of decomposing carbonate, a target bacterial solution is finally obtained, porous organic acid is formed from raw materials suchas triethanolamine borate and 1,4-phenylenebisboronic acid in the presence of a catalyst, the strain in an eluting solution is adsorbed by virtue of the porous organic acid, and a carrier is providedfor the strain; a microorganism and the organic acid are decomposed for compounding and synergistic action, so that scale inhibition is effectively implemented; moreover, the scale inhibitor preparedby the method is decomposable, and has less hazards to the environment.

Description

Technical field [0001] The invention belongs to the field of water treatment, and specifically relates to a preparation method of an environmentally-friendly composite scale inhibitor. Background technique [0002] Scale inhibitors are a class of agents that can disperse insoluble inorganic salts in water, prevent or interfere with the precipitation and scaling of insoluble inorganic salts on metal surfaces, and maintain good heat transfer effects in metal equipment. Due to the increasing shortage of fresh water resources, people pay more and more attention to circulating cooling water treatment agents in industry. Circulating cooling water accompanies the whole production process and accounts for 70-80% of the total water consumption. In industrial production, circulating water is often used to cool the equipment or transfer heat. Circulating water will evaporate part of the water vapor in the system, which increases the salt concentration in the system. High-concentration salt...
