| 摘 要： | 进行了纤维滤料地下水除铁中试研究，试验结果表明纤维滤料具有成熟期短（14d）、除铁效率高的特点。在滤速为20m／s时能将原水中Fe从11．6mg／L去除至0．3mg／L以下。三价铁是影响出水水质的重要因素．应减少曝气后停留时间及控制曝气量以减少滤前三价铁的含量。分析了纤维滤料除铁的机理及特点．确定了纤维滤料过滤器合适的反冲洗强度及步骤。 |

| Abstract: | The ful l-scale experimental study on iron removal from groundwater by fiber filtering m edia has been made.The results showed that fiber filtering media had shorter 'm ature period' of 14 d and higher efficacy of iron removal.Iron in the groundwat er could be removed from 11.6 mg/L to 0.3 mg/L and below.Fe3+ concentration is an important factor which influences the iron removal effect.Reducing retention period after aeration and controlling aeration rate are needed to reduce Fe3+ c oncentration before filters.The mechanism and characteristics of iron removal b y fiber filtering media are discussed.The wash steps and suitable washing rate of fiber filters are put forward. |
| Keywords: | groundwater iron removal fiber filtering media |
