活性炭对对苯二酚的吸附试验研究

在静态条件下,采用活性炭对对苯二酚废水进行处理,比较了不同条件下活性炭对对苯二酚废水的吸附效果,确定了处理废水的pH值、活性炭用量、振荡时间、温度、废水中对苯二酚浓度、振荡速率以及电解质对吸附效果的影响。试验结果表明:在pH值为6.5、活性炭投加量为35g/L、振荡时间3.5h、温度35℃左右的条件下,对质量浓度为100mg/L的对苯二酚废水的处理效果最好,去除率可达99%。

Experimental study on activated carbon adsorbing hydroquinone

Under static condition,hydroquinone-containing wastewater was treated by activated carbon,the adsorption effects of activated carbon forhydroquinone-containing wastewater under different conditions were compared,meanwhile,the influences of pH value,activated carbon dosage,oscillation time,temperature,concentration ofhydroquinone,oscillation velocity and electrolyte of the wastewater on adsorption effect were determined.The results of the test showed that: under the condition that,the dosage of activated carbon was 35g/L,the pH value was 6.5,the oscillation time was 3.5h,the temperature was about 35 ℃,the best treatment effect ofhydroquinone-containing wastewater whose mass concentration was 100mg/L was obtained,the removal rate reached 99%.
