【摘要】：在模擬原沉積物弱堿性及含水率的條件下,分別研究了2種高級氧化反應體系:H_2O_2輔助加入催化劑Fe SO4或Fe2(SO4)3及Na2S2O8輔助加入催化劑Fe SO4或Ca O及熱催化對污染灘涂沉積物中石油烴的去除效果及其影響因素。同時,還模擬研究了長江口潮汐作用對灘涂石油污染修復效果的影響。研究表明:H_2O_2與樣品的質(zhì)量投加比為0.05,FeSO4和Fe2(SO4)3與H_2O_2摩爾投加比均為0.1時,石油烴去除率分別達到48.9%和57.4%;Na2S2O8本身氧化能力較強,單一Na2S2O8與樣品的質(zhì)量比大于0.01時,石油烴去除率達到46%以上;而在Na2S2O8最佳投加比條件下,Fe SO4、Ca O與Na2S2O8摩爾比為0.05和0.9時,去除率分別達到60.4%和51.3%以上,同時最佳催化溫度為50℃。潮汐作用對芬頓試劑氧化修復灘涂石油污染具有促進作用,而高濃度污染灘涂區(qū)域建議采用阻隔修復。
[Abstract]:Under the condition of simulating the weak alkalinity and moisture content of the primary sediment, The removal efficiency of petroleum hydrocarbon from polluted beach sediment by adding FeSO _ 4 or Fe _ 2 (so _ 4) _ 3 and Na _ 2S _ 2O _ 8 as auxiliary catalyst and thermal catalysis were studied respectively by adding FeSO _ 4 or Fe _ 2 (so _ 4) _ 3 and thermal catalysis of two kinds of advanced oxidation reaction systems: W / S _ 2O _ 2 and + Fe _ 2 (so _ 4) _ 4 or Fe _ 2 (so _ 4) _ 3. At the same time, the effects of tidal action on oil pollution remediation in the Yangtze Estuary are simulated. The results show that when the mass ratio of O _ 2O _ 2 to the sample is 0.05% FeSO _ 4 and Fe _ 2 (so _ 4) _ 3 to H _ 2O _ 2 are both 0.1, the removal rate of petroleum hydrocarbon is 48.9% and 57.4% respectively. When the mass ratio of single Na _ 2S _ 2O _ 8 to the sample is greater than 0.01, The removal rate of petroleum hydrocarbon is more than 46%, and the removal rate is 60.4% and 51.3% respectively when the molar ratio of FeSO _ 4 and Na _ 2S _ 2O _ 8 is 0.05 and 0.9, and the optimum catalytic temperature is 50 鈩，
