Problems solved by technology

[0004] In order to solve the above problems, the Chinese Patent No. CN201010541147.3 discloses a scale inhibitor with high calcium and high sulfate radical water quality. Although it has good anti-scaling performance, as time goes by, there are still some scales on the pipeline, which are calcium phosphate scales after analyzing the composition, so there is still room for further improvement of this technology for anti-scaling

Embodiment 1

[0013] Mix 1.0-5.0% sodium dodecylbenzene sulfonate, 0.5-2.5% pentasodium phosphate, 1-3% hydroxyethylene diphosphoric acid, 2-4% aminotrimethylene phosphoric acid, and the rest are pure water Formulated as a scale inhibitor, added to the external drainage of the overflow tank of the pyrite mine wastewater station, 160g of this scale inhibitor was added to every 1ml of the external drainage, and after a one-month on-site pilot test, observe the hanging piece and the inner wall of the test tube None of them scaled, and the water quality of the external drainage was up to standard, and the test results were satisfactory.

Embodiment 2

[0015] Mix 1.0-5.0% sodium dodecylbenzene sulfonate, 0.5-2.5% pentasodium phosphate, 1-3% hydroxyethylene diphosphoric acid, 2-4% aminotrimethylene phosphoric acid, and the rest are pure water Formulated as a scale inhibitor, add it to the external drainage of the overflow tank of the pyrite mine wastewater station, add 200g of this scale inhibitor per 1ml of external drainage, and observe the hanging piece and the inner wall of the test tube after a one-month on-site pilot test None of them scaled, and the water quality of the external drainage was up to standard, and the test results were satisfactory.

Embodiment 3

[0017] Mix 1.0-5.0% sodium dodecylbenzene sulfonate, 0.5-2.5% pentasodium phosphate, 1-3% hydroxyethylene diphosphoric acid, 2-4% aminotrimethylene phosphoric acid, and the rest are pure water Formulated as a scale inhibitor, added to the external drainage of the overflow pool of the pyrite mine wastewater station, 240g of this scale inhibitor was added to every 1ml of external drainage, and after a one-month on-site pilot test, observe the hanging piece and the inner wall of the test tube None of them scaled, and the water quality of the external drainage was up to standard, and the test results were satisfactory.

[0018] Through the above tests, the feasibility, optimal formula and process operation of the special scale inhibitor for high calcium and high sulfate radical external drainage of pyrite mine wastewater station have been determined; after adding the scale inhibitor provided by the present invention, the coupons and pipelines The scaling rate meets the require...

Abstract

The invention discloses an antisludging agent for water with high concentration of calcium and sulfate radical. The antisludging agent is characterized by comprising the following components: 1.0-5.0% of a surfactant, 0.5-2.5% of phosphate, 1-3% of HEDP, 2-4% of ATMP, and the balance of water. The antisludging agent can effectively control scale formation, effectively prevent formation of calcium phosphate scale to further improve the scale inhibition effect, and has an excellent scale inhibition performance.

Description

technical field [0001] The invention relates to a water quality scale inhibitor, in particular to a scale inhibitor used for high calcium and high sulfate water quality. Background technique [0002] Water is the most precious natural resource and a necessary condition for human survival. The protection, utilization and research of water resources have become one of the hottest topics in the world today. my country is a country that lacks water resources. With the rapid development of industry, water consumption is increasing. In many areas, the lack of water resources restricts the development of industrial and agricultural production. In some areas, the shortage of water resources even causes harm to human beings. Survival threats and challenges. [0003] Wastewater lime treatment process mainly includes lime high-concentration mud process and traditional lime treatment process (i.e. low-concentration mud process). , the degree of automation has made great progress, so t...
