Study on Cleaning Optimization of Ultrafiltration Membrane Fouling in Wastewater Treatment Plant
In response to high turbidity pollution issue of wastewater treatment plant,taking the submerged ultrafiltra-tion membrane of a reclaimed water plant as the research object,a set of pilot-scale equipment was construct-ed to simulate the most serious high turbidity pollution in operation,by adjusting the technical parameters of physical cleaning and chemical cleaning,the simulation cleaning of the contaminated membrane was carried out,taking the transmembrane pressure difference as the evaluation index and combining with the economic index in the actual production,the cleaning effect is compared and the more reasonable,convenient and eco-nomical cleaning method is found.By changing the cleaning method and optimizing the existing ultrafiltration membrane cleaning method,the membrane running time,pharmaceutical costs can be greatly reduced,and the membrane service life can be extended.
