| 摘 要： | 水厂中投加粉末活性炭时,由于反应时间非常短,其吸附动力学行为的确定非常重要.利用均相表面扩散模型(HSDM)对粉末活性炭吸附水中2-甲基异莰醇(MIB)及土臭素(geosmin)时的动力学过程进行了模拟.结果表明,只要通过1组吸附动力学实验取得相应的数据,就可以利用均相表面扩散模型HSDM对不同投量下粉末活性炭的吸附动力学过程进行有效的预测,并结合原水中MIB或geosmin的初始浓度、需要处理达到的目标浓度以及粉末活性炭接触时间,确定粉末活性炭的投加量. |

| Abstract: | Because of the short contact time,it is important to determine the adsorption kinetics of powdered activated carbon(PAC) on applying PAC in waterworks.In this study,the application of homogeneous surface diffusion model(HSDM) to the prediction of removal kinetics of MIB and geosmin was introduced.It was found that the kinetic processes under different PAC doses could be predicted with HSDM through only one set of kinetic experiment.It is possible to predict the dosage of PAC with HSDM,if the concentration of the target compounds,the contact time of PAC in waterworks,and the treatment target are determined. |
| Keywords: | homogeneous surface diffusion model(HSDM) powdered activated carbon adsorption kinetics 2-methylisobornel(MIB) geosmin |
