摘要:室内模拟研究了沉积物中不同形态磷在不同浓度铁盐影响下,在沉积层中的垂直迁移转化行为.结果表明,分别向模拟系统投加的10 mL和50 mL的1 mol/L FeCl3溶液,沉积层中磷的含量降低,投加30 mL的1 mol/L FeCl3溶液时,沉积层中磷含量增加.沉积物中适当的铁盐会阻止沉积物磷向水体释放,铁盐浓度过高或过低,在一定程度上都会促进沉积物中磷的释放,实验结果对研究内源磷释放与湖泊富营养化有重要的意义.
A simulation study has been done that vertical transport of conduct of phosphorus in sediment affected by iron inorganic salt. The results showed: when 10 mL or 50 mL of 1 mol/L FeCl3 solutiou were added to the simulation system respectively, phosphorus content in sediments was reduced, however, 30 mL of 1 mol/L FeC13 solution was added, phosphorus content of sediments increased. Appropriate quantum iron inorganic salt will prevent phosphorus in sediment released to the water, otherwise, iron ion quantum added is too high or too low, to a certain extent, will promote the release of phosphorus in the sediments. The results of the study will help further study on the release of the source of phosphorus and lake eutrophication.
