| 摘 要： | 水源水中存在的天然有机物(NOM)会严重影响饮用水的质量。强化混凝能经济有效地去除水源水中的NOM,但对溶解态消毒副产品(DBP)前驱物的去除率不高。基于强化混凝去除水源水中NOM的新方法研究成为了热点。本文论述了吸附、预氧化、磁技术、生物降解4种方法分别与强化混凝联合去除水源水中NOM的研究进展,从技术原理、工艺条件、处理效果、运行经济性等方面对其各自优缺点及应用前景进行了对比和展望。

| Abstract: | The existence of Natural Organic Matter (NOM) in source water seriously affects the quality of drinking water. Although enhanced coagulation can effectively remove NOM in source water, it could hardly remove the dissolved disinfection by-product precursors effectively. To find new methods for NOM removal in source water based on enhanced coagulation becomes a research focus both at home and abroad. The combined technologies of adsorption, pre-oxidation, magnetic technology and bio-degradable with enhanced coagulation to remove the NOM in source water are reviewed in this paper. The advantages and disadvantages of the combined technologies and their applications are analyzed with respect to technical principle, process conditions, removal efficiency, and operation costs. This paper provides a scientific basis and technological support for selecting suitable technology for NOM removal in source water. |
