碳材料在环境工学方面的应用

主要介绍了碳材料在石油废水处理，给排水水质处理、大气治理中的应用。膨胀石墨含有大量孔隙，密度很低，用作吸附材料可以治理石油废水。碳材料可作为生物增殖的载体，分解生物能降解的污染物。用于给排水水质处理，能够提高水质；而经过特殊处理的石墨可以与金属纳米复合，形成金属基石墨层间化合物，改善石墨的抗菌性能。碳材料的比表面积大，可用作气相污染物的吸附脱除材料，在大气污染方面，表现出良好的应用前景。

Carbon Materials Applied in Environmental Engineering

Carbon materials can be used to purify air, water with oil and impurity. After heat-treatment, there are large quantity of vacancy and pore in expanded graphite. The density of this kind of graphite is very low. It can be used to absorb oil in water. The absorbing capacity is larger than that of the active carbon. On the other hands, this graphite can act as the carrier of microorganism that can eat some impurity. With the intercalation of metal in graphite, the property of anti-bacterium can be increased in graphite. With lots of holes, carbon materials can be used as absorbent for waste gas.
