聚氯乙烯膜在废水处理中的研究进展

Research progress of polyvinyl chloride membrane in wastewater treatment

在众多聚合物材料中,聚氯乙烯(PVC)因其较低的成本和优异的性能被用作制备膜材料并广泛应用于废水处理等领域。然而,由于PVC膜具有一定的疏水性,导致废水中的大分子和生物分子(如多聚糖蛋白质)、盐和胶体容易在膜表面和孔隙上吸附或沉积,出现结垢现象,从而影响膜分离性能。因此,改善PVC膜的亲水性和抗污染性能是提高其应用前景的关键。本文重点论述了近几年提升PVC膜亲水性能的有效方法和研究进展。

Among the numerous polymer materials,low-cost polyvinyl chloride(PVC)has been prepared as a membrane material and widely applied in fields such as wastewater treatment due to its excellent performance.However,the hydrophobic nature of PVC membranes leads to the adsorption or deposition of macromolecules and biomolecules(such as polysaccharides and proteins),salts,and colloids from wastewater on the membrane surface and pores,resulting in fouling and affecting membrane separation performance.Therefore,improving the hydrophilicity and anti-pollution performance of PVC membranes is crucial for enhancing their application prospects.This article focuses on the effective methods and research progress in enhancing the hydrophilic properties of PVC membranes in recent years.
