【摘要】 目前，我国饮用水水质的安全性面临着严重的形势。本论文以饮用水水质为研究对象，将电絮凝与微滤工艺相结合，共同对饮用水进行深度处理。电絮凝、微滤联合处理工艺是对饮用水中的氟、腐殖酸和细菌等污染物进行处理。实验研究中还探讨了水体污染物的去除效率及其影响因素—电流密度、污染物初始浓度、极板间距、pH值、共存离子等因素的相关性。通过实验，证明此联合工艺具有较好的可操作性和有效性，其电絮凝-微滤实验装置还具有紧凑和操作灵活的特点。研究成果证明了运用此联合处理工艺对饮用水体污染物的处理方法可行、出水水质可达到国家饮用水卫生标准、是一种较为高效的水处理技术，在生产实践中可以逐步推广应用。更多还原

【Abstract】 At present, China faces serious situation in the quality security of drinking water, thereby it is in urgent need of a superior technology on advanced treatment of those waters. In this paper, we took the drinking water quality as a research object and developed an advanced treatment technology for the drinking water by the combining electrocoagulation and microfiltration process.Electrocoagulation-microfiltration (EC-MF) process aimed at disposing fluorine, humic acid and bacterium in drinking water. The relevance between the removal effect of the pollutants and their influence factors (i.e., current density, initial concentration of the pollutants, pH and co-existing ions, etc) was discussed, and this process was found to be highly operable and effective, with the characteristics of compact and facilitated operation in their equipment.. The results indicated that the way of disposing pollutants in drinking water by this combination process was feasible and the outlet water quality reached the national standard for drinking water. In conclusion, EC-MF process was a highly effective water treatment technique and could be applied in the production practice.更多还原
