摘要
泥炭比重小、质量轻，富含有机质，是一种吸附能力很强的吸油材料。本文通过大量试验论述了泥炭净化含油污水的实验条件和方法。结果表明。泥炭经热加工处理后，由原来的亲水性变成疏水性，在含油污水中实现吸油而不吸水；采用不同的净化方式效果不同，静态方式泥炭可吸附其自身重量的５－１０倍的油，动态吸油高达１０倍以上；藓类泥炭、草木泥炭及木本泥炭对油的吸附效果也不同，分别可吸附油６—９．５Ｌ／Ｋｇ、４—８Ｌ－／Ｋｇ和１—２．５Ｌ／Ｌｇ。
Be cause ic f little proportion,low weight,and containingMrich hulni; matter I)eat is a material thathave strong ability of abso bing oil. in the pater conditions and methods of pun fication of oil--bearing pollutedwater with peat are obta ned from a mumber of tests. The results show that peat becones estranged from water through heating and absorbs oil not water in the water polluted by oil. Different means of purification havedifferent effects. Peat can absorb 5--10 times as much as its own weight in the static state water and 10 timesmore than its own weight in the dynamic state water Different types of peat have (lifferent effects of absorbingoil. Under the same condition the amount of oil that I kilogram of the nossy peat,the herbacous peat or thewoody peat can absorb in the polluted water is respectively 6-9; 5L, 4-8L and 1 -1.5L.
