摘要：研究活性炭吸附对城市污水生化出水中疏水酸、非酸疏水物质、弱疏水物质及亲水物质的去除效果.在静态吸附实验中,当活性炭投加量为0.3g·l-1时,达到吸附平衡后,对DOC和UV254的去除率可分别达到54%和76%,同时能够完全消除生化出水的生物毒性.活性炭吸附对疏水酸和亲水物质均有良好的去除效果,其DOC去除率分别达到50%和80%,对非酸疏水物质和弱疏水物质去除率相对稍低,DOC去除率分别为29%和28%,活性炭吸附对有机物的亲疏水性没有明显偏好.
Activated carbon adsorption is a kind of useful wastewater advanced treatment method. Dissolved organic matter （DOM）in biotreated effluent were fractionated into hydrophobic acids, non-acid hydrophobics, transphilics and hydrophilics through XAD-8/XAD-4 resin. Removal efficiency of DOM fractions through activated carbon adsorption was investigated. When activated carbon dosage was 0.3 g · 1^-1, DOC and UV254 removals could reach 54% and 76%, respectively, and toxicity was totally removed. It was indicated that removal efficiencies of hydrophobic acids and hydrophilics were very high through activated carbon adsorption, its DOC removals were 50% and 80%, while non-acid hydrophobics and transphilics＇were lower, only 29% and 28%. Activated carbon didnt exhibit obvious preference between hydrophobic and hydrophilic DOM.
