几种吸附材料在含油废水处理中的应用

Application of Several Absorbing Material to Treat Oil Wastewater

含油废水的来源广泛、成分复杂且对环境危害严重,吸附法是处理含油废水常用的方法,吸附剂性能的优劣对处理含油废水有至关重要的影响。介绍几种典型的吸附材料包括活性炭、高吸油树脂、粉煤灰和膨润土;活性炭是处理含油废水最常用的吸附材料,高吸油树脂则是新型的有机吸附剂,粉煤灰来源广且价格低廉,膨润土资源丰富;几种吸附材料各有优点缺点,其特性、吸附机理、在含油废水处理中的应用也不尽相同,通过比较分析,提出了未来用于含油废水处理吸附材料的发展趋势。

The oil wastewater is comes from many source,complex ingredient and polluted badly.Adsorption method is often used to process the oil wastewater,adsorption capacity is important to the process the oil wastewater,the typical adsorbing material included：active carbon,oil-adsorption resin,fly ash,bentonite;the active carbon was often used to process the oil wastewater,oil-adsorption resin is a new kind organic adsorbent,the fly ash was enough and cheap,bentonite was also enough.Every kind of the material have its own advantage and defect,the characteristics,adsorption mechanism and application of absorbing material are also different.By comparing and analyzing,some prospects in adsorbing material to treat oil wastewater are also presented.
