摘要
以脱水污泥为原料,以氯化锌为活化剂,用浸渍微波辐射法制备了活性污泥吸附剂。通过单因素实验和正交实验,探讨了制备条件对吸附性能的影响。结果表明,制备污泥吸附剂的适宜条件为:干污泥与浓度40%的氯化锌溶液按质量比为1∶3.0浸泡,微波功率595 W,辐照时间4.0 min。污泥含碳吸附剂吸附碘吸附值为412 mg/g以上,亚甲基蓝吸附值为67 mg/g以上。
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.
