Embodiment 1

[0021] Both salicylic acid and mandelic acid are weakly acidic skin care product additives, and a large amount of acid-containing residues will be produced in the production process. The invention applies the waste and residues generated in the production process of skin care products to soil improvement, which can not only solve the problem of chemical production The problem of waste liquid treatment can turn waste into treasure and yield benefits. Most of the production of salicylic acid uses sodium phenate carbon dioxide carboxylation method, and most of them are prepared by sublimation method. After sublimation, 5%-7 % of the sublimation residue, which contains about 30%-40% of salicylic acid, using the solubility of salicylic acid, the residue is heated to 6 times the water to dissolve, and the impurities are filtered. The mother liquor is cooled to precipitate salicylic acid and its derivatives, and the straw, furfural slag, and weathered coal are pulverized with a pulver...

Embodiment 2

[0023] The salicylic acid production residue was dissolved by heating with 2 times water, and the impurities were filtered. The mother liquor is cooled to precipitate salicylic acid and its derivatives, and the straw, coconut shell activated carbon, and peat are pulverized with a pulverizer and passed through an 80-mesh sieve; the pulverized raw materials are added to the above-mentioned salicylic acid and its derivatives, and mandelic acid is added , desulfurized gypsum, humic acid, biomass coke, urea, Thiobacillus, Sulfolobus and Rhodococcus, which were obtained from the Institute of Microbiology, Chinese Academy of Sciences.

[0024] The soil conditioner comprises 63 parts by weight of salicylic acid and its derivatives, 5 parts of mandelic acid, 50 parts of straw, 25 parts of coconut shell activated carbon, 25 parts of peat, 22 parts of desulfurized gypsum, 41 parts of humic acid, 5 parts of biomass coke, 1.1 parts of urea, mix the above raw materials evenly and boil them,...

Abstract

The invention discloses an environment-friendly soil conditioner and a preparation method thereof. The environment-friendly soil conditioner comprises salicylic acid and derivatives thereof. The environment-friendly soil conditioner and the preparation method thereof have the advantages that the soil conditioner is simple in preparation process and rich in raw material source, the soil conditioneris a granular soil conditioner prepared by mixing raw materials according to a certain proportion range, the proportion range is reasonable, and the effects of the raw materials are synergistically enhanced; pollution discharge in the preparation process is avoided; irrigation water quantity for crops planted in soil improved by the soil conditioner can be reduced by about 1 / 3 as compared with the traditional irrigation water quantity of the same local crops planted in soil not improved by the soil conditioner; by the preparation method, waste generated in the cosmetics production industry can be treated; by the soil conditioner, saline and alkaline land or heavily alkalized soil can be improved into arable land, crops can well grow in the improved land, and evident economic benefits areachieved.

Description

technical field [0001] The invention belongs to the field of soil improvement, and in particular relates to an environment-friendly soil improver for alkaline soil and a preparation method thereof. Background technique [0002] At present, there are 8.4 million square kilometers of salinized land in the world, distributed in 112 countries and regions, from frigid, temperate to tropical regions, from America, Europe, Asia to Australia, there are a lot of saline, dry, The hardened and barren saline-alkali land, due to improper irrigation, precipitation and other factors, the area of ​​secondary salinized land is still increasing. [0003] China is a country with a large amount of saline-alkali land, ranking third among the top 10 countries with saline-alkali land area. China's saline-alkali land is distributed in 17 provinces including the Northwest, Northeast, North China, and coastal areas, mainly including the eastern coastal saline land, the saline soil in the Huanghuai-H...
