摘　　要：用改性陶粒和原陶粒进行平行过滤对比试验,并对改性陶粒去除有机物的规律进行了探讨,同时对改性陶粒去除有机物的影响因素(进水有机物浓度、空速、pH值)进行了试验研究.试验结果表明,改性陶粒去除有机物明显优于原陶粒;进水有机物浓度越大、空速越小,处理效果越好;pH值略呈酸性时,去除有机物效果最好.Based on the comparison of the filtration experiment results with modified ceramsite and crude ceramsite,we analyze the principle of removing organic matter with modified ceramsite. Some factors influencing the removal of organic matter with modified ceramsite（such as the influent concentration of the organic matter, filtration velocity and pH value）were investigated. The experiment indicates that the removal efficiency increased with the increase of the influent concentration and the decrease of velocity. When the pH value is slightly acid, we get the best removal effect of organic matter.
