城市河湖水体水质净化和保持新技术的应用实践

Application of New Technology to Purification and Maintenance of Urban River and Lake Water

介绍了以"外循环透析处理"和"水体高效自净"相结合的水环境治理新技术,并对该技术在城市湖泊水体综合治理项目中的应用进行了分析。该技术以高效、全面、稳定的前沿物化技术和成熟生态技术相结合,开创了水生态保护与修复的新模式。通过超磁透析保护与原位生态修复的方式,可快速实现水体水质的净化,为水生态自身修复创造了有利条件,实现了水环境的短期净化和长期修复的目的。超磁透析技术可高效去除水中的悬浮物、藻类和非溶解性COD,大幅改善水体的透明度,快速削减营养盐,恢复水体水质,再与原位生态修复技术结合,可使河湖水生态系统的功能得到有效的恢复。

A new water environment management technology combining external circulation dialy- sis treatment with efficient water self-purification was introduced. The application of the technology to the comprehensive management of the urban river and lake water was analyzed. With the combination of high efficiency, comprehensive and stable advanced technique with mature ecological technique, the technolo- gy created a new mode of water ecological protection and restoration. The super magnetic dialysis protec- tion and in situ ecological restoration can purify water quality quickly, creating favorable conditions for water ecological self-restoration capacity and achieving the short-term purification and long-term restora- tion of water environment. The super magnetic dialysis protection technology can effectively remove SS, algae and non-soluble COD, greatly improve the transparency of water, quickly reduce nutrient and re- store water quality, and its combination with in situ ecological restoration can effectively recover the river and lake ecosystem function.
