Title:
DEVICE FOR EXTRACTING HYDROPHOBIC DISSOLVED HUMIC ACID FROM FRESH WATER BODY
Document Type and Number:
WIPO Patent Application WO/2018/072281
Kind Code:
A1
Abstract:
A device for extracting hydrophobic humic acid from a fresh water body comprises a raw water supply unit, a pretreatment unit, a reverse osmosis concentration unit, an acidity-alkalinity adjusting unit, an organic matter extracting unit, a first water tank (8), a general control system (5), a second water tank (16), an automatic pH adjusting unit and a humic acid extracting unit; wherein the pH automatic adjusting unit comprises a pH sensor, a second dosing device (17), a third dosing device (18) and a metering dosing pump; the acidity-alkalinity adjusting unit and the automatic pH adjusting unit are both automatic, thereby not only saving labor force and reducing production costs but also having a high accuracy for pH adjustment; the humic acid extraction unit separates the humus acid from other dissolved organic matter through filtration via a filtering membrane, and then elute and purify the same through a elution device (13) to improve the purity of the humic acid. The extraction device is simple in structure, of a high degree of automation and convenient to operate.
