Abstract

The invention provides an extracting device for hydrophobic dissolution humic acid in a fresh water body. The device comprises a raw water supply unit, a preprocessing unit, a reverse osmosis concentration unit, a pH value regulating unit, an organic matter extraction unit, a first water tank, a master control system, a second water tank, an automatic pH value regulating unit and a humic acid extracting unit, wherein the automatic pH value regulating unit comprises a pH sensor, a second dosing device, a third dosing device and a metering dosing pump; both the pH value regulating unit and the automatic pH value regulating unit are full automatic, so that labor force is saved, the production cost is lowered, and the pH value regulating accuracy is high; according to the humic acid extracting unit, humic acid and other dissolved organic matter are separated through filtering of a filter membrane, and due to leaching and purifying of a leaching device, the purity of humic acid is improved. The extracting device for hydrophobic dissolution humic acid in the fresh water body is simple in structure, high in automation degree and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of concentration, in particular to a device for extracting hydrophobic dissolved humic acid in fresh water. Background technique [0002] Dissolved organic matter is a kind of natural macromolecular organic mixture that can pass through a filter membrane with a pore size of 0.45 μm. It comes from animal and plant secretions and their residual decomposition products, including humic acid, fulvic acid and non-humic substances. Humic acid has a large molecular weight and plays an important role in the deposition and flocculation of pollutants. Humic acid can be divided into hydrophobic humic acid and hydrophilic humic acid. Among them, hydrophobic humic acid is more non-polar and more likely to combine with new pollutants such as PAHs. It is currently a hot spot in geochemical and environmental science research. . However, the concentration of humic acid in water is extremely low, generally around 1-3mg / L, an...
