摘要
地下水水质较好,不易污染,比较安全可靠。但是地下水中铁、锰含量过高给人们的生产生活带来很多的不便和危害。实验通过对溶解氧量的研究,发现溶解氧在一定范围内的变化对生物除铁除锰效率的提高无显著影响,原水溶解氧达到3 mg/L即可满足运行要求。
Groumdwater has many advantages as compared with surface water, however ,there are more or less Fe^2＋and Mn^2＋ in groundwater,which cause a variety of health involvement. The conclusion has been drew a through the experiment that dissolve oxygen can modify the result of the removal rate of manganese and iron. Consider the reasons of the economy and biological filter media,the dissolve oxygen level around 3mg/L is goodenough.
