印染废水生化出水中各类有机物在小型活性炭床吸附过程中的去除效果
Removal effect of different organic fractions from bio-treated effluent of dye wastewater by carbon adsorption bed
摘要
Abstract
Removal effects of four different DOM fractions, hydrophobic acids, non-acid hydrophobics, tasnsphilics and hydrophilics separated by XAD-8 and XAD-4 resins, in biotreated effluent of dye wastewater by carbon adsorption process were studied. And the molecular distributions of dissolved organic matter were determined by UF method using UF membrane. Carbon adsorption process had noticeable effect on DOM removal,with the higher removal efficiency of coal activated carbon. It was indicated that removal efficiencies of hydrophobic acids and hydrophilics were very high through activated carbon adsorption, while non-acid hydrophilics and tasnsphilics' efficiencies were lower. The adsorption of organic matter whose molecular weight is less than 10 k contributed greatly to the test results.关键词
