| 摘 要： | 考察了抽吸式PVDF中空纤维超滤设备对钢铁污水厂二级出水的处理效果,以及作为反渗透预处理的措施.结果表明,PVDF超滤膜可以有效去除水中浊度、细菌、胶体和有机颗粒,同时还具有较高耐污能力的特点,可以保持较长的生产周期.使用不同药剂进行化学清洗,发现柠檬酸具有较好的清洗效果,污水中金属离子结垢是膜污染的主要原因.

| Abstract: | The effect is investigated on the use of the equipment of hollow fiber PVDF ultra filtration membrane to treat the sewage form a steel mill. The result shows that the ultra filtration function film of PVDF can effectively get rid of turbid degree, bacterium, colloidal and organic particle in water and it can also prevent pollution effectively to keep longer production cycle. Application of different medicaments in chemical cleaning discovered that using the citric acid can obtain good effect, metallic ion scaling is the main reason of membrane pollution. |
