应用环境同位素技术研究华北典型流域水循环机理的展望

, 2002
华北水问题日益严重,而水循环机理研究尚显得薄弱。环境同位素水文学是研究流域水循环过程变化的新的技术途径。它利用水中水分子所含的同位素含量的变化,可以判断大气降水的水蒸气的来源;定量分析坡地的产汇流产生机制,进而研究"大气降水—地表水—土壤水—地下水"的相互作用关系;彻底查明流域"四水"转化关系,创新和发展水循环模式。本文主要介绍同位素技术的原理及其在日本、斯里兰卡、河北平原等地应用实例,最后,对应用此技术研究华北典型流域水循环,从"大气—土壤—植被"界面水循环机理、坡地径流的产汇流机制 ...

高铝粉煤灰资源化过程重金属环境影响研究

, 2013
针对高铝粉煤灰碱石灰烧结多资源利用工艺过程中重金属元素迁移规律和潜在环境影响量化问题,基于物质流分析方法,分析该工艺中重金属元素的边界输入输出和内部迁移规律.结果表明,输入端54%的铅元素由工业过程废弃物即高铝粉煤灰带入,其余来自工业原材料.输出端64%的铅元素进入产品,其余部分进入废弃物.该工艺主要环境排放节点在烧结和水泥生产环节.通过定义相对环境排放指数(REEI),比较分析该工艺与拜耳法工艺重金属排放情况.结果表明,该工艺单位氧化铝产量铅元素净排放显著降低,铬元素环境排放量与拜耳法基本持平 ...
