Abstract

The invention discloses a biological scale inhibitor. The scale inhibitor is prepared from, by weight, 55-70 parts of biological raw materials, 15-25 parts of inorganic zinc salt, 1-3 parts of sodium hydroxide, 4-9 parts of sodium lignin sulfonate, 2-5 parts of dispersant and 30-65 parts of solvents. The biological raw materials are one or two of potatoes and sweet potatoes, the dispersant is stearamide, and the solvents are one or more of ethanol, acetone and chloroform. According to the formula, phosphorus-free materials are adopted, the phenomenon of water eutrophication cannot be caused in the using process, the scale inhibitor is safe in use, water cannot be polluted after the scale inhibitor is used, raw material price is low, the materials are wide in range, and the prepared scale inhibitor is good in degradation effect, has good scale inhibition performance and is high in applicability.

Description

technical field [0001] The invention relates to the technical field of scale inhibitors, in particular to a biological scale inhibitor and a preparation method thereof. Background technique [0002] The groundwater level in some areas of our country is significantly affected by the Yellow River system. In some areas, because of the irrigation canals of the Yellow River, there is water all year round and the groundwater level is high, but there is no drainage canal. The local soil is saline-alkali soil and aeolian soil, which contains a lot of soluble salt. Since the local area is in an arid and semi-arid area, the precipitation is small and the evaporation is large, so the salt dissolved in the water tends to accumulate on the soil surface. Coupled with improper farming management, the watering method in this area is mostly flood irrigation, or there is irrigation but no drainage in low-lying areas, so that the groundwater table rises quickly and salt accumulates, turning t...
