| 摘 要： | 对于桥水库流域内暴雨径流中锰含量形态的研究表明,锰主要以悬浮状态存在,其中易释放的、潜在释放的和非释放形态的锰所占比例分别为10％、60％和30％.以溶解态迁移的锰极少.流域内的锰矿-含锰页岩带提高了暴雨径流中总锰的浓度,对于桥水库水质造成了一定的影响.

| Abstract: | The transport characteristics of manganese in storm runoff of the northern mountain area in Tianjin was studied.The majority of the manganese in the runoff water existed in suspended solids. The dissolved manganese determined was no more than 9 % of the total. Five fractions of manganese in suspended solids of the runoff were determined. The results showed that the percentages of releaseable, potential releaseable and irreleaseable manganese in the suspended solids were 10%, 60% and 30%, respectively. In the storm runoff, manganese was transported mainly as the oxides and the lattice-inlaid fractions.The zone of manganese mineralization in this area contributes to the total concentration of manganese in the storm runoff. Therefore, it had certain influence on the water quality of Yuqiao Reservoir. |
