活性炭吸附法去除废水COD的研究

摘要

The monothetic method for the technological conditions of the adsorption of COD from electroplating wastewater by using activated carbon has been studied. The influence of dosage of activated carbon, pH, temperature and time on COD removal rate was studied. The results indicate that the COD removal rate and the residual concentration of COD in treated water are 37.66 % and 66.08 mg/L under the following conditions: dosage of activated carbon 6.0 g/L, pH of wastewater 7.5, temperature 25 ℃, and adsorption time 60 min.%采用单因素法对活性炭吸附电镀废水中COD的工艺条件进行了研究,考察了pH、活性炭用量、反应时间、反应温度对去除率的影响.结果表明,当pH为7.5、吸附时间为60 min、活性炭用量为6.0 g/L、温度为25 ℃时,COD去除率达到37.66 %,出水COD 66.08 mg/L.
