摘要
文章主要研究了改性活性炭的吸附性能在降低废水COD方面的作用。通过改变水样中的改性活性炭投加量、反应的温度和反应试液的p H,确定了最适宜改性活性炭吸附的条件,吸附后的改性活性炭经过热再生,可以循环使用3次。同时与未改性活性炭相比,改性活性炭具在吸附性能具有较大的优势。
The paper mainly studied the adsorption of modified activated carbon in reducing the COD of waste water. Through changing the amount of modified activated carbon, pH, and the temperature of solution, we determined the most appropriate condition in degradation of COD of waste water. Also, the modified activated carbon can be recycled 3 times through thermal regeneration. Compared with the unmodified activated carbon, the modified activated carbon has more advantage in the adsorption properties
