煤基活性炭在饮用水处理中的应用现状及发展趋势 -

阐述了煤基活性炭的特性及其吸附机理,分析了粉状活性炭和颗粒状活性炭在饮用水处理方面的应用优势,指出单纯使用活性炭难以去除水中的大分子有机污染物,活性炭吸附组合工艺已经成为水处理行业中的发展趋势,臭氧+生物活性炭组合工艺是目前最重要的水处理工艺,我国大部分自来水厂的深度水处理均采用该组合工艺,该工艺可以有效去除水中有机污染物,并预测煤基活性炭及其组合工艺将是未来饮用水深度处理发展方向。 The characteristics and adsorption mechanism of coal-based activated carbon were described.The application advantages of powdered activated carbon and granular activated carbon in drinking water treatment were analyzed.It is pointed out that it is difficult to remove macromolecular organic pollutants in water by using activated carbon alone.The combination process of activated carbon adsorption has become a developing trend in the water treatment industry. The ozone biological activated carbon combination process is the most important water treatment process at present,and the combination process is used in the advanced water treatment of most waterworks in China.This process can effectively remove organic pollutants in water and predict that coal-based activated carbon and its combination process will be the development direction of advanced treatment of drinking water in the future
