Two pH adjustment unit, humic acid extraction unit and total control system; the device for extracting soil hydrophobic humic acid provided by the present invention has simple structure, convenient operation, high degree of automation, and can conveniently and effectively extract hydrophobic humic acid and humic acid Other impurities are separated to obtain a high-concentration hydrophobic dissolved humic acid solution.

Description

technical field [0001] The invention relates to the field of humic acid extraction, in particular to a device for extracting soil hydrophobic humic acid. Background technique [0002] Humic acid is an organic mixture formed by animal and plant residues through complex physicochemical and biological processes, accounting for about 60-80% of the total organic matter in soil. [0003] Humic acid plays an important role in agriculture and the environment. According to current research, humic acid can stimulate the growth of crops, improve the soil pH environment, and reduce soil compaction. Humic acid is a carbon source for microorganisms. In addition, humic acid can interact with toxic heavy metal ions and organic pollutants in the environment, changing the environmental behavior of pollutants. In particular, the combination of hydrophobic humic acid and persistent organic pollutants such as PAHs is more stable, controlling its migration and transformation rules and biologic...
