摘要

摘要: 水体富营养化与藻类过度繁殖是全球性环境问题。传统铜盐除藻剂效果好、成本低，但铜离子的二次污染和死亡藻细胞的沉积会进一步恶化水质。研究提出一种新型铜基微孔膜的自然水体除藻净化技术，以实现高藻水的快速净化和回用，其基于铜膜-水界面反应释放出具有氧化作用的铜离子，在无外加药剂的情况下，对水中藻类的去除率达到100 %。通过耦合物理性截留和催化降解作用，该技术可有效地去除不同种类的污染物。滤液中浊度去除率达到98.87%，且有机物的紫外吸光值、微囊藻毒素和总有机碳分别降低了28.54%，42.9%和36.8%。铜基微滤膜对有机物的去除性能优于传统有机膜，显著提升了水质和提高了再利用潜力。通过快速水力反冲洗，铜基微滤膜迅速恢复初始通量，平均值维持在65525.65 L/（m²·h）。滤液中铜离子含量最高仅为1.22×10^-5 mol/L，远低于GB 5749—2022《生活饮用水卫生标准》，为可持续水处理和水生态保护提供了技术参考。

Abstract: Eutrophication and algal blooms are global environmental concerns. While traditional copper-based algicides are effective and cost-efficient， they cause secondary copper ion pollution and degrade water quality due to the accumulation of dead algae. This study introduces an innovative method for simultaneous algae removal and water purification using a copper-based microfiltration membrane that enables rapid treatment and facilitates high-quality water reuse. Through the oxidation effect of copper ions released at the membrane-water interface， the copper-based microfiltration membrane achieved 100% algae removal without additional chemicals. It combined physical interception with catalytic degradation， effectively eliminating a wide range of pollutants. The system removed 98.87% of turbidity while reducing ultraviolet absorbance， microcystin-LR concentrations， and total organic carbon by 28.54%， 42.9%， and 36.8%， respectively. Compared to traditional polymeric microfiltration membranes， the copper-based membrane demonstrated markedly enhanced efficiency in removing organic contaminants， significantly improving treated water quality and reuse potential. Through rapid hydraulic backwashing， the copper-based membrane effectively recovered its initial flux and maintained a consistent water flux of 65525.65 L/（m²·h）. The copper ion concentration in the filtrate remained at approximately 1.22×10^-5 mol/L， well within the safety limits for drinking water. This study provides valuable insights for sustainable water treatment and aquatic ecosystem protection.
