  • 摘要: 紫茎泽兰目前已被列入我国首批外来入侵物种,排在第一位。为达到有效防控紫茎泽兰扩散的目的,对紫茎泽兰进行资源化利用是相对较佳的途径。通过对紫茎泽兰炭化处理后用于处理生活污水中的有机物,实现以害制废。采用等温吸附实验研究了炭化紫茎泽兰用作吸附剂吸附生活污水中有机物的吸附特性,并讨论了炭化紫茎泽兰吸附生活污水中COD的初始浓度、吸附时间、吸附温度、吸附剂投加量等影响因素。结果表明,当炭化紫茎泽兰的投加量为0.05 g,吸附接触时间为2 h,吸附温度为20℃,180 r/min,生活污水中进水COD浓度大于1 000 mg/L时,去除率可达62.9%。采用Langmuir、Freundlich吸附等温式对吸附平衡数据进行了拟合,结果表明吸附等温线符合Freundlich模型。
    Abstract: Eupatorium adenophorum spreng was listed at the top on the first batch of Chinese invasive species. In order to prevent and control the spread of Eupatorium adenophorum Spreng, resource utilization is a better way. After carbonized, Eupatorium adenophorum Spreng was used for adsorbing organic pollutants in domestic wastewater, which can realize "using harm to deal with waste". The adsorption characteristics of adsorbing organic pollutants in domestic wastewater by carbonized Eupatorium adenophorum Spreng was studied by introducing the isothermal adsorption experiment. Some influencing factors of the adsorption such as initial COD, adsorption time, adsorption temperature, adsorbent dosage were also discussed. The results indicated that under the conditions of the dosage of carbonized Eupatorium adenophorum Spreng of 0.05 g, adsorption contact time of 2 h, adsorption temperature of 20℃, 180 r/min, COD of influent wastewater of more than 1 000 mg/L, the removal rate of influent COD reached 62.9%. The adsorption equilibrium data for organic pollutant were described with the Langmuir, Freundlich adsorption isotherm equations. The results showed that the adsorption isotherm equation was in accordance with Freundlich isotherm equation.
