多孔膜蒸馏处理高盐废水的污垢抑制策略

摘要

多孔膜蒸馏技术因其能高效去除高盐废水中的溶解物质而备受关注。然而，在实际应用过程中，膜的污垢问题严重影响了其处理性能和稳定性。为了提高膜的抗污垢能力，本文探讨了几种污垢抑制策略，包括膜表面改性、添加清洁剂以及优化操作条件等。通过优化这些策略，能够显著降低膜表面的污染程度，从而提高膜蒸馏系统的处理效果和运行周期。这些策略的有效性为高盐废水处理提供了新的思路，尤其在降低能源消耗和提升膜寿命方面具有重要意义。

Abstract

Porous membrane distillation technology has attracted considerable attention due to its high efficiency in removing dissolved substances from high-salinity wastewater. However, during practical application, membrane fouling seriously impairs the treatment performance and stability of the technology. To enhance the anti-fouling capability of membranes, this paper explores several fouling mitigation strategies, including membrane surface modification, addition of cleaning agents, and optimization of operating conditions. By optimizing these strategies, the degree of fouling on the membrane surface can be significantly reduced, thereby improving the treatment efficiency and operation cycle of the membrane distillation system. The effectiveness of these strategies provides new insights for high-salinity wastewater treatment, and is of great significance especially in reducing energy consumption and extending membrane lifespan.
