Abstract
The invention provides a device for adopting two-stage combined resins to extract fulvic acid in a water body. The device comprises a raw water supply unit, a pretreatment unit, a nanofiltration and concentration unit, a power of hydrogen regulating unit, a water tank, a master control system, a filtration and purification unit and a fulvic acid extracting unit, wherein the fulvic acid extracting unit comprise a leaching device, an alkali liquor agent tank, an organic liquid agent tank, a primary adsorption and enrichment device, a primary ion exchange device, a secondary adsorption and enrichment device and a second ion exchange device. The filtration and purification unit can separate fulvic acid and insoluble impurities, and the primary adsorption and enrichment device and the secondary adsorption and enrichment device in the fulvic acid extracting unit and respectively corresponding ion exchange devices conduct adsorption and purification on organic matter dissolved in concentrated water to obtain a high-concentration fulvic acid extracting solution. The device for adopting the two-stage combined resins to extract fulvic acid in the water body is simple in structure, high in automatic 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 fulvic acid from water by using two-stage resin combination. Background technique [0002] In fresh water and sea water, fulvic acid has important ecological and environmental functions. Fulvic acid interacts with toxic and harmful substances such as heavy metals in water, thereby affecting the transformation, migration and fate of pollutants in the environment. In natural water bodies, the absolute content of fulvic acid is very low, and the concentration is generally 0.1-5mg / L. However, how to efficiently extract high-concentration humic acid from water is an urgent problem to be solved. [0003] Li Huijie published a master's degree thesis titled: Extraction and Characterization of Humic Acid and Fulvic Acid (Huazhong University of Science and Technology, Major in Architecture and Civil Engineering), and disclosed a method for extraction and pur...
