Description

Device for separating and enriching soluble organic resin in fresh water Technical Field The invention relates to the technical field of organic matter extraction, in particular to a separation and enrichment device for soluble organic matter resin in fresh water. Background Soluble organic matter, also known as water-soluble organic matter. The soluble organic matters in the fresh water mainly comprise acidic substances such as humic acid, fulvic acid and the like, and small molecular substances such as polypeptide, polysaccharide, amino acid and the like. The polypeptide, polysaccharide, amino acid and other small molecular substances have small content and are easy to decompose by microorganisms, while humic acid, fulvic acid and other acidic substances have large molecular weight and are difficult to decompose. Humic acid and fulvic acid are important regulators for influencing the color, taste and pH value of water. Research on soluble organic matters in fresh water is also of great significance to environmental science. Chinese invention patent (application number: CN201610920648.X, the name is a device for extracting fresh water organic matters by combining reverse osmosis and resin), discloses a device for extracting fresh water organic matters by combining reverse osmosis and resin, and designs a device which can simply and effectively separate and extract the fresh water and can obtain high-purity organic matters solid by combining reverse osmosis and resin, and has higher automation degree. After the fresh water organic matter extracting solution with a certain concentration is obtained through filtering and concentrating treatment, the extracting solution flows through an adsorption column filled with resin, organic matters in the fresh water are enriched and separated by the adsorption column, the resin is leached by a specific solution after enrichment and separation of a batch of materials are finished each time, so that the adsorption of the organic matters by the resin is relieved, and then the solution and the organic matters are evaporated and separated, so that the high-purity organic matter solid is obtained. However, the device adopts automatic operation, and the resin is desorbed and regenerated once after a batch of extracting solution materials are enriched, so that if the extracting solution is excessive, and the extracting solution contains organic matters exceeding the adsorption limit of the resin, the resin reaches the saturation level, but the extracting solution remains and continuously flows through an adsorption column, so that the loss of the organic matters in the extracting solution is caused, the concentration of the organic matters can be changed when the organic matters flow into water from which the organic matters are separated, the concentration and extraction are needed again to be carried out for alignment and enrichment and separation again, and energy waste is caused, and because the resin is regenerated after 2-6 hours, the resin is far from reaching the saturation state when the extracting solution is less, and if the resin is desorbed and regenerated, the resin is not completely utilized, so that the time cost and the regeneration cost are increased. Therefore, the device for separating and enriching the soluble organic resin in the fresh water is provided, and the subsequent operation steps caused by the fact that the use condition of the resin cannot be accurately controlled in the prior art are solved. Disclosure of Invention The invention aims to provide a device for separating and enriching soluble organic matters from fresh water, which can detect the resin in an adsorption column to determine whether the resin in the adsorption column is saturated or not so as to accurately judge the separation and enrichment of the organic matters in the next step, avoid the loss of the organic matters caused by the fact that the adsorption column is still used for enriching and separating the organic matters due to the saturation of the resin, and simultaneously avoid the problems of time waste, regeneration frequency increase, regeneration cost increase and the like caused by the fact that the resin in the adsorption column is not saturated after the enrichment of primary materials, and then the resin is leached and washed out of the organic matters and regenerated, so that the enrichment and separation of the next batch of materials are suspended. In order to achieve the above purpose, the present invention provides the following technical solutions: A device for separating and enriching soluble organic resin in fresh water comprises: The adsorption column is made of a glass round tube or other materials with acid resistance, resin is filled in the adsorption column, the resin is one or more of XAD-8 resin, DAX-8 resin and XAD-7 resin, two ends of the adsorption column are sealed by filter screens to prevent the resin from losing from the adsorption column, and th
