SIMULATION ON THE EFFECTS OF REAGENT INJECTION CONDITION ON CONTACT EFFICIENCY OF BIOREACTIVE ZONE

摘要: 近些年来,原位生物反应带技术在污染场地修复中越来越受到关注。原位生物反应带的修复效果直接受注入试剂与污染物接触效率的影响。应用GMS 6.0软件分别模拟研究了质量缩放因子(SFM)和体积缩放因子(SFv)对接触效率(Ev)的影响。结果显示,Ev与SFM和SFv均呈正相关关系,但当SFM>2.0时,SFM对Ev的影响较小;当SFv>1.5时,Ev的增加幅度降低,乳化油迁移性能下降。由此可见,研究质量缩放因子和体积缩放因子对接触效率的影响对原位生物反应带修复工程的设计、运行和管理具有一定的指导意义。Abstract: In situ bioreactive zone has profound application prospect for contaminated sites remediation in recent years． The efficiency of bioreactive zone was affected by contact efficiency of injection reagent and the pollutants． GMS 6. 0 was used to investigate the effects of mass scaling factor ( SFM ) and volume scaling factor ( SFv) on the contact efficiency ( Ev ) ． The simulation results indicated that Ev was positively correlated with SFM and SFv，respectively． However，SFM had slight influence on Ev ，while SFM was over 2. 0; increase rate of Ev was decrease while SFv was over 1. 5，and the transport performance of emulsified oil was impacted． Therefore，it is important for design，operation and management for the bioreactive zone to study the effects of mass scaling factor and volume scaling factor on the contact efficiency．
