Abstract Based on the application of membrane separation technology in water purification,we conduct water purification treatment through ultrafiltration membranes,microfiltration membranes,various biological membranes,and compare their effects. Through diverse experiences in water quality testing and iterative optimization of self-made water purifiers,we guide students to construct a problem-solving thinking model,stimulate their innovative consciousness,cultivate their engineering technology thinking,and reflect the significance and value of interdisciplinary learning.
