Phosphate-free scale inhibitor for water treatment

Abstract

The invention relates to the technical field of water treatment, in particular to a phosphate-free scale inhibitor for water treatment, which is good in effect, low in cost and high in scale inhibition capacity and cannot cause secondary pollution to the water body. The phosphate-free scale inhibitor is characterized by comprising the following components: polyacrylic acid, hydrogen peroxide, rubber tannin, mirabilite, sodium citrate, zinc chloride, sodium molybdate, polyaspartic acid, acrylic acid sulfonic acid, polyepoxysuccinic acid and triethanolamine. When the phosphate-free scale inhibitor is used, the components are taken in proportion, water is added, and after a solution is prepared, the solution is added to water treatment equipment; compared with the prior art, the phosphate-free scale inhibitor is non-toxic and non-phosphorus, main organic components are easily degraded, the environmental pollution cannot be caused, and thus the subsequent treatment cost is greatly reduced.

Description

Technical field: [0001] The invention relates to the technical field of water treatment, in particular to a non-phosphorus scale inhibitor for water treatment with good effect, low cost, strong scale inhibition ability and no secondary pollution to water bodies. Background technique: [0002] Because organic phosphonic acid is an effective water treatment agent with dual functions of corrosion inhibition and scale inhibition, it has been widely used in water treatment for a long time. However, these phosphorous compounds are finally discharged directly into natural water bodies as waste. , has an impact on the environment. With the enhancement of environmental protection awareness, the environmental protection department has restricted the use of phosphorus. Therefore, the development of phosphorus-free green water treatment chemicals has become an important topic in the current research on water treatment chemicals. Invention content: [0003] Aiming at the shortcomings a...
