摘　　要：近年来，已有不少学者将胶质粘土改性应用于处理工业有机废水．但粘土表面因具有极性氢氧基，故对有机物的吸附能力差．若用适当的改良剂改良之，使其获得具有亲有机性的表面，则可吸附水中的有机污染物．我们采用了不同烷基正胺改良粘土，并将其成型为颗粒状，经测试其对水中有机物如苯的吸附能力良好．Due to the polar hydroxide groups in bentonite the absorption of organic compounds on bentonite is weak. It is proposed that some ogranopilic surface ofbentonite can be obtained with appropriate agents. The modified bentonite can be used as an adsorbent in the treatment of industrial wastewater.The modified bentonite with different n-alleglamines was abtained and the adsorptive ability for benzene in water was determined. The modified bentonite has high adsorption activity for benzene in water. However, the modified bentonite is in the state of powder and not suitable for industrial application.In this project, a kind of organic binder is selected to shape the modified bentonite powder into a suitable granular form and the optimun operating conditions of a adsorber filled with the granular modefied bentonite in the treatment of oganic wastewater is determined.
