| 摘 要： | 采用底泥为研究对象,通过对底泥吸附等温曲线数据的拟合、改性前后对磷的吸附量变化以及底泥中各形态磷的含量分布变化来探讨底泥在水体富营养化进程中所起的作用。研究发现:吸附参数与吸附等温式均得到很好的拟合;加入三氯化铁改性后的底泥对磷的吸附量得到有效增加;不同形态磷的含量分布中,Fe/Al-P在底泥中占主要的比重,达到63.35%~57.11%,Res-P占的比重最低,Ca-P在各个底泥中的含量相差不大。

| Abstract: | Taking the sediment as a research object,the thesis studies the role of the sediment in the process of eutrophication by the sediment adsorption isotherms fitting,the adsorption changes before and after modification and the form changes of the phosphorus in the sediment.The findings are as follows：（1）the adsorption data fit well with the isotherms;（2）the adsorption of the modification sediment is improved remarkably when the phosphate is added;（3）in the different phosphorus distribution,the Fe/Al-P accounts for the large proportion,as high as 63.35%~57.11%,while the Res-P for the lowest,and the Ca-P contents difference in sediments is small. |
