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 pharmaceutical composition and an application thereof. The water treatment pharmaceutical composition contains amino acids having a scale and corrosion inhibition function, tetracycline antibiotics having sterilization functions, and an enzyme for playing a synergistic effect on the amino acids and antibiotics. The invention further discloses an application of the water treatment pharmaceutical composition in water treatment. A performance estimation result of the pharmaceutical composition indicates that the scale inhibition rate of calcium carbonate scale inhibition is larger than 99%, the corrosion rate of a dynamic simulation test is 0.024 mm / a, and the minimum number of heterotrophic bacteria within 72h can reach 1.4*10<2> pieces / ml. The water treatment pharmaceutical composition is low in dosage, free of phosphorus, strong in scale inhibition ability, good in corrosion inhibition, good in sterilization effect and long in 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 ...
