Abstract

The invention discloses an inorganic ceramic ultrafiltration membrane cleaning agent and a preparation method thereof. The cleaning agent comprises coconut oil fatty acid monoethanolamide, polyoxyethylene fatty alcohol sodium sulfate, starch acetate, dioctyl sulfosuccinate sodium salt, sodium hexametaphosphate, sodium tripolyphosphate, phenylethylene/maleic anhydride/octadecylamine copolymer, kieselguhr, protease, alcamines, a corrosion inhibitor and deionized water. The cleaning agent is prepared by the following steps: adding coconut oil fatty acid monoethanolamide, starch acetate, dioctyl sulfosuccinate sodium salt and sodium hexametaphosphate into deionized water so as to obtain a mixture I, adding polyoxyethylene fatty alcohol sodium sulfate, sodium tripolyphosphate, phenylethylene/maleic anhydride/octadecylamine copolymer, kieselguhr and alcamines into remaining deionized water so as to obtain a mixture II, and adding remaining components into the mixture of the mixture I and the mixture II so as to obtain the cleaning agent. The cleaning agent has a good cleaning effect, and also has the advantages of improving the service efficiency of filtration membranes, prolonging the service life of the filtration membranes and reducing the number of times for replacing the ultrafiltration membranes.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to an inorganic ceramic ultrafiltration membrane cleaning agent and a preparation method thereof. Background technique [0002] Alumina membranes, zirconia membranes, and alumina-zirconia hybrid membranes are the most widely used inorganic ceramic membranes, and are generally applied by ultrafiltration. In the practical application of ultrafiltration technology, the most restrictive problem is membrane fouling during use, which is manifested as: the flux decays with time, the pressure difference on both sides of the membrane and the pressure drop through the membrane gradually increase, and when the pollution is serious, use The filtering process is difficult to continue. Therefore, determining the mechanism and influencing factors of membrane fouling, controlling the degree of membrane fouling, removing fouling and restoring membrane flux have always been the f...
