竹炭对微污染水中有机污染物的吸附

he elimination of charcoal to CODMn、UV254、UV410 in running water was determined in this study. The effect on charcoal diameter, met, adsorption time and pH of the water solution to charcoal adsorption character was studied. The best adsorption condition of charcoal to CODMn、UV254、UV410 was indicated by the orthogonal experiment. Recording to the study, the remove rate of bamboo charcoal to each index became higher come along with the particle size and was the highest when the bamboo charcoal dosage was 100mg,the adsorption time was 1h.Weak acid conditions was favorable to the bamboo charcoal adsorptive capacity and pH value 4.0 was the best condition. The best condition of dynamic adsorption was identified in the study as follows: charcoal particle size was 100-200 mesh, the quality was100mg, vibration absorption was 1 h, the raw water pH is 4.
