蔗糖改性纳米铁原位反应带修复范围影响因素研究
首发时间:2014-07-22
摘要:本论文以粗砂和细砂作为含水层介质,通过注入井向模拟含水层中注入蔗糖改性纳米铁浆液,研究介质类型、地下水流速、浆液注入浓度和注入方式对反应带修复范围的影响,实验结果表明:当浆液浓度较小、介质粒径及注入速度较大时,更有利于形成较大范围的反应带;采取分次注入的方式能够提高反应带初始宽度,地下水流速一定的条件下,反应带扩展速率与注入方式无关;扩展后的反应带具有不均一性。

Study on influence factors of remediation area of in-situ reaction zone with sucrose-modified nanoiron
Abstract:Coarse and fine sand were chosen as aquifer medium in this paper, and sucrose-modified nanoiron slurry was injected to simulated aquifer through injection wells in order to study the influence factors of remediation area of in-situ reation zone (IRZ) with sucrose-modified nanoiron, such as medium type, flow velocity of groundwater, slurry concentration and injection way. The experiment results indicated that it tended to form larger remediation area with lower slurry concentration, larger medium size and injection speed; spliting injection into several times could increase the initial width of IRZ, however, expanding rate of the area had nothing to do with injection way when the flow velocity of groundwater was constant; expanded remediation area was inhomogeneity.
Keywords: environmental engineering sucrose-modified nanoiron in-situ reaction zone average width expand
