高盐浓水回用RO系统膜污染防控及PWT全流程解决方案
Journal: Ecological Environment and Protection DOI: 10.12238/eep.v8i2.2523
Abstract
针对高盐浓水处理过程中二氧化硅结垢与生物污染耦合作用导致反渗透系统运行效率低下的技术难题,本研究基于某化工厂脱盐水系统改造工程,系统分析了高盐浓水的水质特征及其膜污染机制,提出了PWT三重协同防护体系。通过使用PWT高硅阻垢剂、以及RO专用清洗剂、非氧化性杀菌剂。构建了涵盖阻垢(预防)、抑菌(控制)、清洗(恢复)的三维协同防护体系。工程实践表明：该方案使浓水RO系统化学清洗周期延长1倍,降低运行成本。研究结果为高盐废水零排放系统的稳定运行提供了创新性的技术范式,具有显著的环境效益和经济效益。
