DATB改性吸附剂的表征及处理石油废水研究

无

摘要:

用十二烷基三甲基溴化铵(DATB)对膨润土、海泡石、粉煤灰和硅藻土改性，并通过TG、XRD和IR等手段进行了性能表征；研究了时间、pH、吸附剂用量等因素对吸附剂处理石油废水效果的影响及其吸附性能。结果表明，在最佳实验条件下,对COD、油类、氨氮和挥发酚的去除率最高分别可达86.79%、92.33%、78.64%、87.05%；吸附剂对石油废水中污染物的吸附符合Freundlich或Langmuir吸附等温式。

Abstract:

Bentonite、Sepiolite、Fly Ash and Diatomite were modification by DATB, and the structure of the sorbent were investigated by TG、XRD and IR. The effects of time、pH、amount of adsorbent and other factors were studied ,based on the adsorbent effect of treatment of oil wastewater. It is indicated that under the best experimental condition, the removal rate of COD, oil, ammonia nitrogen and volatile phenol may separately reach 86.79%, 92.33%, 78.64%, 87.05%; The pollutant adsorption conforms to Freundlich or the Langmuir adsorption isotherm.
