Adsorption of Organic Pollutions in Micro-polluted Water by Bamboo Charcoal

SUN Xin-yuan,WU Guang-qian,ZHANG Qi-sheng  
The elimination of charcoal to CODMn、UV254、UV410 in running water was determined in this study.The effect of charcoal diameter,dosage,adsorption time and pH of the water solution on 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 along with the particle size and was the highest when the bamboo charcoal dosage was 100 mg and the adsorption time was 1 h.Weak acid condition 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 was 100 mg,vibration absorption was 1 h,and raw water pH is 4.
