| 摘 要： | 依据斯托克斯原理制作了水淘选颗粒物分级装置,考察了流量对于颗粒物分级的影响,确定了适宜的操作流量。同时在选定的实验条件下对现场悬浮颗粒物进行了分级,并用吸管法对方法的分级效率进行了检验。结果表明,水淘选装置对悬浮颗粒物各粒级颗粒物的分级效率在50%~95%之间,分级效果较好。同时运用建立的方法对在长江、长江口以及黄河获得的悬浮颗粒物进行了现场分级,获得了不同粒级悬浮颗粒物,并进而采用改进的SEDEX方法进行了磷的赋存形态分析,结果表明:有机磷、自生磷灰石磷主要存在于细颗粒物中,而碎屑磷则主要集中粗颗粒物中。

| Abstract: | Water elutriation that was based on Stokes' low could separate particles into different size classes.In this study,water elutriation apparatus was applied to explore the water flow rate that affected the efficiency of the water elutriator,and appropriate water flow rate was determined.Water elutriator was also used to separate the suspended particulate maters in field with determined conditions.The efficiency of the equipment was analyzed with the pipe method.The result indicated that the efficiency ranged ... |
