摘　　要：以甲基橙溶液为有机废水降解模型,松果为原料制备活性炭,在超声条件下进行了活性炭吸附降解有机废水实验,研究了吸附剂用量,吸附温度,吸附时间,超声功率,初始浓度等因素对吸附效果的影响。实验结果表明:超声对于吸附具有明显的促进作用,吸附温度越高,吸附效果越好;吸附剂最佳用量为300 g/g,最佳吸附时间为20 min,最佳吸附温度为50℃。Taking the methyl orange solution as organic wastewater degradation model,the organic wastewater adsorption experiment was studied using self-made active carbon which took the pinecone as raw materials under ultrasonic conditions in this paper.The effects of the dosage of sorbent,absorption temperature,absorption time,ultrasonic power,the initial concentration on the adsorption were researched.The experimental results show that ultrasonic wave promoted the adsorption obviously;the higher the adsorption temperature was,the better the adsorption effect became;the optimal dosage of absorbent adsorption was 300 g/g,the best time for adsorption was 20 min and the best temperature for adsorption was 50 ℃ in the experiment.
