摘要:
常规处理工艺对NOR突发污染去除能力有限，去除率最高为22%。因此本论文研究了投加粉末活性炭工艺对NOR的突发污染的去除效果，在对粉末活性炭的吸附容量试验中，Freundlich吸附等温式对粉末活性炭吸附去除NOR污染的拟合优于Langmuir吸附等温式拟合，且符合拟二级动力学方程。粉末活性炭吸附去除NOR有很好的效果，粉末活性炭投量相同时，随着污染物初始浓度的增加，粉末活性炭的吸附容量逐渐增大；当NOR浓度较高时，需要增加粉末活性炭的投加量才能明显提高NOR的去除率。
Abstract:
Conventional treatment process on NOR sudden pollution removal ability is limited and the high-est removal rate of 22%. In the adsorption capacity test, the adsorption isotherm of powder activated carbon adsorption to remove pollution of NOR fitting is better than the Langmuir adsorption isotherm curve fitting and in line with the proposed secondary dynamics equation. Powder activated carbon adsorption removal of NOR has very good effect; powder activated carbon dosage phase at the same time, with the increase of the initial concentration of the pollutants, powder activated carbon adsorption capacity increased gradually. When NOR concentration is higher, it needs to increase the dosing quantity of active carbon powder to improve the removal rate of NOR.
