Choosin adsorbent is the ke issue of this method. The cla p p p g y y adsorbents have large surface area and large adsorption capacities, and can remove waste effectively. The adsorbents are inex ensive, easil obtained and will not cause second ollution, so the have ood a li- p y p y g pp cation ros ects for the treatment of wastewater. p p Subj ect HEADING adsorbent, clay, sewage disposal , ,, [ 1] , , ( 10~ 30), , , , , , , 60 , , , , - 1 , , , , , - , , 2.4~ , 40 3 2.8k / dm , 1330~ 1430e , 2: ~ 200 0. 01 0.005 g 1,(Al4Si8O23( OH) # nH2O), , 94 , , ~ 100 [1] , , + , , NH4 , 1987 , 1997( ) :,:257062 第 10 卷
