摘要
目的研究粉末活性炭应急处理苯酚水源水污染的可行性,提供应对突发的水污染处理的理论依据和技术指导.方法用浑河水配制一定质量浓度苯酚污染水,模拟突发的苯酚水污染,进行粉末活性炭(PAC)对苯酚的吸附性能以及投加工艺参数的试验.结果结果表明PAC对苯酚的吸附性能曲线符合弗兰德里希(Freundlich)吸附模式.在苯酚的平衡质量浓度为0.002 mg/L时,粉末活性炭对其吸附容量为1.46 mg/g;PAC对苯酚有较快的吸附速率,吸附20 min就能够达到其吸附容量的90%以上;比表面积大的木质炭是应急处理苯酚水污染的最佳炭种;PAC投加的炭浆质量浓度对处理效果有一定的影响;当溶液的pH值小于10时,PAC对苯酚有较高的吸附效果.结论对突发的苯酚污染,投加粉末活性炭是切实可行的应急处理措施.
Study the possibility that the powdered activated carbon meets the emergency treatment for phenol water pollution , to provide a theoritical basis and a technique guidance to the abrupt water pollution trouble. The method is that with Hun River water for raw water, imitating abrupt phenol water pollution, a study was carried out by adding the powdered activated carbon for emergency treatment. Studying the adsorption function of powdered activated carbon on phenol and the influences on phenol removal by powdered activated carbon. The result expresses that the powdered activated carbon＇s adsorption isotherm on phenol to match the Freundlich adsorption mode. The adsorption capacity of phenol by powdered activated carbon is about 1.46 mg/g, while the equilibrium concentration of phenol is at 0.002 mg/L, The adsorption rate of PAC on phenol is rapid that it is up to more 90 % of it adsorption capacity in 20 min;PAC category with huge surface area is the best for the treatment; The concentration of adding of PAC and the categarty of PAC have some influence on removal of phenol by PAC, while the dosage has great influence; The value of pH is controlled at lower 10 ; In a word, for abrupt Hun River phenol water pollution, the process of powdered activated carbon is a possibility and an effective process for the emergency treatment.
