| 摘 要： | 文章基于渗透反应墙技术,通过实验室柱实验分析不同浓度的SO42-和Cl-单独作用下Fe0降解TCE的效果.结果表明:在相同Fe0条件下,随SO42-浓度增大,出水口TCE去除率提高,且SO42-在TCE降解反应中由抑制作用逐渐转换为促进作用；此外随Cl-浓度增大,出水口TCE去除率呈下降趋势,且Cl-在TCE降解反应中... |

| Abstract: | Column experiments were done to determine effects of sulfate and chloride ion on TCE degradation by ZVI-PRB.Results showed that sulfate and chloride ion had a dual effect on TCE degradation in the system of ZVI-PRB.As sulfate concentration increased,the efficiency of TCE degradation got better.Sulfate could inhibit the reaction when its concentration was low,however,when its concentration increased,sulfate had a promoting action to the reaction.As chloride ion concentration increased,the efficiency of TCE d... |
