石油污染土壤超聲波凈化實(shí)驗(yàn)研究.pdf

1、華北電力大學(xué)碩士學(xué)位論文中文摘要石油污染已經(jīng)使土壤遭受嚴(yán)重破壞，直接危害人類生產(chǎn)與生活。本文主要以實(shí)驗(yàn)研究考察超聲波處理石油污染土壤的效果，研究各個(gè)影響因素對(duì)處理效果的影響，找出最佳的處理?xiàng)l件，并對(duì)土壤中原油污染物清除機(jī)制進(jìn)行探討。通過(guò)實(shí)驗(yàn)研究表明超聲波對(duì)土壤中石油污染物的凈化效果明顯，土壤類型對(duì)凈化效果具有顯著J性影響。超聲波并沒(méi)有選擇性地氧化降解某種石油烴化合物，由超聲空化引起的解吸作用和真空過(guò)濾是實(shí)驗(yàn)過(guò)程中土壤總石油烴(TPH)減

2、少的主要途徑。本研究結(jié)果表明超聲波技術(shù)用于石油污染土壤修復(fù)是可行并且是有效果的。關(guān)鍵詞:超聲波凈化，石油污染土壤，總石油烴，方差分析英文摘要Petroleum一eontaminated5011haseausedseriousenvironmentaldamagesandintrodueedanumberofeeologiealandhumanhealtheoneerns.InthisPaPer，aseriesoflaboratoryex
