摘 要: | 目的]研究植物独角莲对城市垃圾渗滤液中有机物的修复效果。方法]通过对渗滤液进行不同浓度的稀释和配合化学絮凝剂的处理,检测独角莲对渗滤液的重要有机物衡量指标COD(化学需氧量)、BOD(五日生化需氧量)及NH3-N(氨氮)的降解效应。结果]独角莲具有在滤液中生长迅速、抗性强和降解效率高的特性,但在100%渗滤液原液(RL)与100%处理后的渗滤液(TL)处理下,由于渗滤液毒性较强,植物在此浓度下的修复效果有限;化学絮凝剂FeCl3处理和独角莲的共同作用可以有效降低较高浓度的渗滤液中的BOD和COD浓度,且TL中的NH3-N含量下降也更显著。结论]该研究为利用植物处理垃圾渗滤液提供了一个良好的备选材料。

Abstract: | Objective]The research aimed to study the remediation effect of Typhonium giganteum on the organic matter of landfill leachate.Method] Through treatment of leachate dilution and combination with the chemical flocculants,the remediation effects of Typhonium giganteum on important organic matter parameters containing COD,BOD and NH3-N in leachate were analyzed.Result] Typhonium giganteum had the characters of fast growing,high resistance and high degradation capability,but showed the low remediation effection under 100% raw leachate and 100% treated leachate condition because of strong toxicity of leachate.Method of combination of FeCl3 and Typhonium giganteum could reduce the contents of BOD and COD in high concentration leachate,and NH3-N content significant reduced.Conclusion] The study provides a good candidate plant for leachate bioremediation using plant. |
