Embodiment approach

[0020] According to a preferred embodiment of the present invention, the water treatment chemical composition does not contain phosphorus, that is, the water treatment chemical composition does not contain conventional phosphorus-based corrosion inhibitors and / or phosphorus-based corrosion and scale inhibitors. In this preferred embodiment, the amino acid has the effect of scale and corrosion inhibition, and the synergistic use of the enzyme and the amino acid can enhance the effect of scale and corrosion inhibition. Therefore, the water treatment chemical composition can not only obtain better It not only has excellent scale and corrosion inhibition performance, but also avoids the defects of environmental pollution caused by the large use of phosphorus-containing chemicals as scale and corrosion inhibitors in traditional water treatment chemicals.

[0021] In the present invention, the water treatment chemical composition may further contain water. The water content in the w...

Abstract

The present invention discloses a water treatment agent composition, which contains an amino acid having a scale inhibiting and corrosion inhibiting effect, a beta-lactam antibiotic having a sterilization effect, and an enzyme cooperating with the amino acid and the antibiotic and providing a synergy effect. The present invention further discloses applications of the water treatment agent in water treatment. According to the present invention, the performance evaluation results of the water treatment agent show that the calcium carbonate scale inhibiting rate is more than 99%, the corrosion rate of the dynamic simulation test is 0.022 mm/a, and the number of the 72 h heterotrophic bacteria can minimally achieve 1.5*10<2>/ml; and the composite agent has characteristics of low use amount, no phosphorus, strong scale inhibiting capacity, good corrosion inhibiting performance, excellent sterilizing effect, and long lasting time.

Description

technical field [0001] The invention relates to a water treatment agent composition and the application of the composition in the water treatment process. Background technique [0002] With the rapid development of the world economy, the global water resource shortage and water pollution problems have been seriously faced by people. Domestic urban industrial water accounts for about 80% of the total urban water consumption, while industrial cooling water consumption accounts for about 2 / 3 of industrial water consumption, and cooling water consumption in the petroleum and petrochemical industry accounts for a larger proportion, accounting for about 2 / 3 of industrial water consumption. 80%-90% of that, so saving industrial cooling water is very necessary. Reasonable use of water treatment chemicals to increase the concentration of circulating water not only solves the energy problem of energy saving and water conservation, but also solves the environmental protection problem ...
