摘要
本文从活性炭表面的物理性质和化学性质,介绍了活性炭吸附的一般机理。综述了活性炭在城市给水、工业废水及城市污水深度处理中的研究进展;混凝—活性炭吸附工艺在净水工程中的应用;臭氧—生物活性炭技术去除水中有机污染物的工艺;MBR/PAC组合工艺及工业上使用石灰石与活性炭联合去除污染物的技术;从活性炭吸附性能指标的选择、有机物分子量的分布、活性炭的改性等方面,提出了活性炭在水处理应用上的问题和展望。
In this paper,based on the physical and chemical properties,the general adsorption mechanism of activated carbon is introduced.It reviews the progress of the application of activated carbon in urban water supply and treatment process of domestic sewage and industrial wastewater;the application of coagulation-activated carbon adsorption process in water purification;ozone and biological activated carbon process to remove organic pollutants in water;MBR / PAC integrated technology as well as the industrial technology of using limestone and activated carbon to remove pollutants.Finally,the questions and prospects in application of activated carbon for water treatment are proposed from the respects of index selection of adsorption capacity,the molecular weight distribution of organic matter,the modification of activated carbon and so on.
