摘要
介绍了膨润土的基本特性及其在油田污水处理中的研究情况。天然膨润土经改性后,可吸附去除油田污水中的油、烃类衍生物、注聚残留聚合物及表面活性剂;负载金属氧化物的改性膨润土可对光催化氧化产生协同效应,提高光催化氧化油田污水中有机物的能力;在高压下将膨润土制成薄膜,对油田污水中的无机离子有一定的截留去除作用。
The property of bentonite and its application in the treatment of oil field wastewater are introduced. Modified bentonite can be used as adsorbent to remove oil, hydrocarbon and its derivatives, COD,polymer and surfactant from oil-field wastewater. Modified bentonite loaded with metal oxide has a synergetic effect on photocatalytic oxidation, which can improve its capability of degrading organic substances in oil field wastewater. Bentonite can be compacted to clay membrane under high pressure, which has a certain effect of retaining inorganic ions in oil-field wastewater.
