摘要

土壤中受多環芳香烴化合物 (PAHs)及氯酚等有機物污染問題愈受重視，而芳香族化合物及氯酚在環境中由於自然因素如森林火災、油品及有機溶劑不當棄置為主或人類相關的製程而生成，再藉由水或空氣途徑污染土壤。而運用植生復育受有機污染物之土壤，為近年來廣受重視整治技術，本研究中，運用黑麥草與黃豆整治復育受有機物污染的土壤，並另外添加二氧化錳 （δ-MnO2）觸媒質，藉此比較不同處理的土壤對芘 （Pyrene）的降解情形，以人工添加Pyrene作為污染土壤，利用盆栽試驗種植黑麥草及黃豆，本試驗分為四種處理，分別為對組照、不種植、添加5%的有機質、添加5%的有機質與1% 二氧化錳 (δ-MnO2)、添加1%的二氧化錳（δ-MnO2）觸媒使用植物降解及植物配合觸媒四種不同處理的降解效果。結果顯示添加5%的有機質於Pyrene濃度為150 mg kg-1、300 mg kg-1、450 mg kg-1之污染土壤中，種植黑麥草對Pyrene降解率分別為93%、92%、89%，種植黃豆對Pyrene降解率分別為90%、93%、88%，而添加1% 二氧化錳（δ-MnO2）觸媒Pyrene污染土壤中，種植黑麥草Pyrene降解率分別為90%、90%、87%，種植黃豆對Pyrene降解率分別為89%、91%、90%，結果顯示種植黑麥草與黃豆對三種不同Pyrene濃度污染土壤之降解率可達87%~93%，對照組Pyrene濃度污染土壤之降解率可達80%~85%，與添加1% δ-MnO2觸媒之Pyrene污染土壤之降解率有顯著差異，建議以黑麥草和黃豆植生復育處理受Pyrene污染土壤。

In the soil organic matter contamination concerns and so on polycyclic aromatic hydrocarbon compound and chlorphenol has received takes seriously. But aromatic compound and cholrphenol in environment. Because natural factor like forest-fire oil quality and organic solvent not, when abandons primarily or humanitys related system regulation like metropolis and the industry activity produces. Again because of water or in air way contaminated soil ground water.
Phytoremediation is an emerging technology for the remeaiation.Using plants for the remediation of the organic pollutant soil. In recent years phytoremediation is an emerging technology of the soil remediation. this study used ryegrass (Lolium perenne) and soy bean (Glycine max) improvement of the organic matter pollution soil. Also added catalysts manganes oxide (δ-MnO2) to compare different treatment the degradation of pyrene.This research carries on increases Pyrene to take the contaminated soil artificially, the use pot experiment planter ryegrass (Lolium perenne) and soy bean (Glycine max).Each treatment had four replicates. Control、not planted、5% OM additions、5% OM additions and 1% MnO2、1% MnO2 additions. The result showed that increases 5% raise earth in the Pyrene density is 150 mg kg-1, 300 mg kg-1, of contaminated soil in 450 mg kg-1, the ryegrass to the Pyrene degeneration rate respectively is 93%, 92%, 89%. the soy bean to the Pyrene degeneration rate respectively is 90%, 93%, 88%. But increases 1% MnO2 in the Pyrene density is 150 mg kg-1, 300 mg kg-1, of contaminated soil in 450 mg kg-1 the ryegrass to the Pyrene degeneration rate respectively is 90%, 90%, 87%. the soy bean to the Pyrene degeneration rate respectively is 89%, 91%, 90%. The result demonstrated that the ryegrass and soy bean pyrene degradation reached to 87%~93%. The control ryegrass and soy bean pyrene degradation reached to 80%~85%. And is increasing 1% MnO2 catalyst to have degeneration of rate the Pyrene contaminated soil the remarkable difference, therefore suggested that if plants by the perennial ryegrass and soy bean phytoremediation processing the Pyrene contaminated soil.
