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 invention discloses a water treatment medicament composition. The water treatment medicament composition contains amino acid, aminoglycoside antibiotics and enzyme, wherein amino acid has effects of scale inhibition and corrosion inhibition, the aminoglycoside antibiotics have a bactericidal effect, and enzyme is cooperative with amino acid and antibiotics and has a synergistic effect. The invention also discloses application of the water treatment medicament composition in water treatment. A performance evaluation result of the water treatment medicament composition shows that the scale inhibiting ratio of calcium carbonate inhibition performance is more than 99%, the corrosion rate of a dynamic simulation experiment is 0.025mm/a, and the number of heterotrophic bacteria in 72h at least can reach 2.1*10<2> per ml. The water treatment medicament composition does not contain phosphorus and is low in dosage, strong in scale inhibition performance, good in corrosion inhibition performance, excellent in sterilizing effect and long in time of duration.

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 ...
