Method (2) The use effect of various manufacturers at home and abroad is uneven, there is a certain degreasing effect, but it cannot meet the requirements of high-quality products, and the service life of the general degreasing medium is 1 to 3 years, and the price is relatively expensive. The operating cost is also high. Durin

Example Embodiment

[0018] According to a kind of method that the present invention effectively removes oil content in aqueous solution, comprise the steps: (1) metal fiber or alloy fiber or inorganic material fiber or any one (i.e. selected fiber) in above-mentioned fiber and inert powder The mixture is filled in the holding container with a porosity of not less than 50%; (2) The oil-containing aqueous solution to be treated flows through the holding container at a certain flow rate, so that the water-in-oil or oil-in-water in the oil-containing aqueous solution The emulsified phase is destroyed under the action of the filling material, and promotes the aggregation and growth of oil particles; (3) The oily aqueous solution after the deoiling treatment of the bearing container is passed into the oil-water clarification separation tank, so that the oil in the oily aqueous solution passes through Clarify and float on the aqueous solution, and then separate from the aqueous solution; (4) The clean aq...

Abstract

An effective method for removing oil content in an aqueous solution comprises the following steps: (1) filling a mixture of an inert powder with one fiber selected from metal fiber, alloy fiber and inorganic fiber into a carrying vessel, by a packing density with porosity not less than 50%; (2) passing an oily water solution to be treated through the carrying vessel with a certain flow, so as to destroy an oil-in-water or water-in-oil emulsion phase in the oily water solution under the action of the filling material, and promote agglomeration of oil particles; (3) introducing the oily water solution treated by the carrying vessel into an oil-water clarification separation tank, so as to float oil in the oily water solution through clarification; and (4) discharging clean water solution with oil content removed from a lower part of a clarification and separation tank, and discharging removed oil content from the upper part of the clarification and separation tank. The invention has the advantages of good oil removal effect, simple structure, convenient operation and low cost, and at the same time can effectively filter out other solid impurities in the water solution.

Description

Technical field: [0001] The invention relates to a method for effectively removing oil in aqueous solution, which belongs to the technical field of material purification and purification in metallurgy, chemical industry and material industry. Background technique: [0002] Solvent extraction has been widely used in the purification and purification of materials, especially in the production of metal elements and their salts. Solvent extraction is to mix, clarify, and separate the organic phase and the aqueous phase, and use the chemical potential difference between the extracted substance in the organic phase and the aqueous phase to purify and purify the extracted substance. The so-called organic phase is a mixture of extractant and solvent oil in a certain proportion, and the so-called aqueous phase is a soluble aqueous solution containing the extracted substance. The mixing process of solvent extraction will inevitably produce fine organic phase particles, that is, solve...
