摘　　要：随着水处理技术的发展,酰胺反渗透膜在工业和民用领域得到了广泛应用。然而,这类膜材料在含氯溶液中使用时容易发生氯化劣化,影响其性能和使用寿命。文章通过对比分析氯化劣化与亚硝酸修复效果,探索亚硝酸对劣化膜的修复潜力及其机理。实验采用标准的劣化模拟与修复流程,详细评估了修复前后膜的物理与化学性质变化,以及透水性能和截留率的变化。结果显示,亚硝酸能有效恢复因氯化劣化受损的酰胺反渗透膜的部分性能,为实际工业应用中的膜材料维护提供了一种可能的化学修复策略。With the development of water treatment technologies,amide reverse osmosis membranes have been widely used in industrial and civil fields.However,these types of membrane materials are susceptible to chlorine degradation when used in chlorinated solutions,affecting their performance and lifespan.This study explores the potential and mechanisms of nitrite acid in repairing degraded membranes by comparing the effects of chlorine degradation and nitrite repair.The experiments utilized standard degradation simulation and repair processes,thoroughly assessing the changes in the physical and chemical properties of the membranes before and after repair,as well as the variations in water permeability and retention rates.The results demonstrate that nitrite acid can effectively restore some of the functions of the amide reverse osmosis membranes damaged by chlorine degradation,offering a potential chemical repair strategy for membrane maintenance in practical industrial applications.
