一、概述粉末活性炭(PAC)用于水的脱色、除臭、除味历史已久。它与粒状活性炭 GAC 相比,主要优点是设备投资省,价格较便宜,吸附速度快,对短期及突发性水质污染适应能力强,故英、美、日等国至今仍广泛应用.美国八十年代初期每年在给水处理中所用 PAC 约25000吨,且有逐年增加趋势,八十年代末,美国已对近40种有机物采用 PAC 吸附处理
First, an overview Powdered activated carbon (PAC) for water bleaching, deodorant, deodorant has a long history. Compared with granulated activated carbon GAC, its main advantage is that it is widely used in Britain, the United States, Japan and other countries because of its investment in equipment saving, cheaper price, faster adsorption speed and adaptability to short-term and unexpected water pollution. In the early decade of the decade, the PAC used in water treatment was about 25,000 tons per year, which has been increasing year by year. In the late 1980s, the United States has adopted PAC adsorption treatment for nearly 40 kinds of organic compounds
