Embodiment 1

[0013] 1.0~5.0% sodium dodecylbenzene sulfonate, 0.5~2.5% pentasodium phosphate and 98.5~92.5% pure water are compounded into scale inhibitors, which are sent to the outside of the overflow pond of the pyrite mine wastewater station Add 160g of this scale inhibitor to every 1m of external drainage. After a one-month field test, it was observed that the coupons and the inner wall of the test tube were not scaled. The external drainage water quality was up to the standard and the test results were satisfactory.

Embodiment 2

[0015] 1.0~5.0% sodium dodecylbenzene sulfonate, 0.5~2.5% pentasodium phosphate and 98.5~92.5% pure water are compounded into scale inhibitors, which are sent to the outside of the overflow pond of the pyrite mine wastewater station Add 200g of this scale inhibitor to every 1m of external drainage. After a one-month field test, it was observed that the coupons and the inner wall of the test tube were not scaled. The external drainage water quality was up to the standard and the test results were satisfactory.

Embodiment 3

[0017] 1.0~5.0% sodium dodecylbenzene sulfonate, 0.5~2.5% pentasodium phosphate and 98.5~92.5% pure water are compounded into scale inhibitors, which are sent to the outside of the overflow pond of the pyrite mine wastewater station Add 240g of this scale inhibitor to every 1m of external drainage. After a one-month field test, it was observed that the coupons and the inner wall of the test tube were not scaled. The external drainage water quality was up to the 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 external drainage of pyrite wastewater stations have been determined; after adding the scale inhibitor provided by the present invention, the coupons and pipes The fouling rate meets the index requirements, with high scale inhibition performance and good effect.

Abstract

The invention discloses a scale inhibitor for high calcium and high sulfate radical water quality. The scale inhibitor is characterized by comprising the following components of: 1.0-5.0 percent of surfactant, 0.5-2.5 percent of phosphate and the balance of water. The scale inhibitor can effectively control the scale formation and has favorable scale inhibition property.

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 ...
