Abstract

By means of microwave,adding ZnCl2 to the sewage sludge,which produced a new absorbent.Effect of preparation conditions on adsorbing capability was disscussed with single factor and multifactors experiment,the result showed that the optimum absorbent manufacture process are based on the following conditions:the weight ratio of dry sewage sludge to ZnCl2(40%) is 1 ∶3.0,the microwave power is 595 W,and the radiation time is 4 min,the number of I2 adsorption of carbonaceous adsorbent derived from sewage sludge will be up to 412 mg/g and the number of methylene blue adsorption will be up to 67 mg/g.
