摘要
Abstract
The reverse osmosis membrane of a leachate treatment plant in Chengdu city is selected as the research object after three years of operation,combined with the influent water quality,the material structure,chemical composition and mineral composition of the facial mask scale on the surface of the polluted membrane elements are comprehensively analyzed,the morphological structure of the membrane surface and its element composition are evaluated,and the cleaning effects of pollutants in different cleaning sequences are studied.The test results indicate that membrane fouling comprises inorganic fouling primarily of calcium carbonate,organic fouling dominated by aromatic compounds and polysaccharides,along with minor amounts of colloidal substances such as Fe(OH)3 and SiO2.The membrane cleaning test shows that the acid washing-alkali washing-acid washing process can effectively remove pollutants inside the membrane.关键词
