摘要利用燃煤废弃产物粉煤灰吸附处理含有三氯苯酚的废水的技术在工业生产中已经开始应用。用粉煤灰处理含有三氯苯酚的废水既廉价又能达到符合排放标准的去除效果。本实验研究选择使用粉煤灰吸附处理含有三氯苯酚的废水。实验研究了粉煤灰的投加量、pH值对粉煤灰吸附三氯苯酚的影响、反应时间的影响、反应温度对吸附效果的影响、以及超声微波组合反应和粉煤灰共同作用吸附三氯苯酚吸收的复合影响，测定了不同温度下的吸附等温线，并计算和构建了吸附动力学和吸附热力学的模型。实验结果表明，处理浓度为1mg/L三氯苯酚废水时吸附反应达到平衡时间约为50min,，粉煤灰的最佳投加量为80mg；最佳pH值7；三氯苯酚的去除率达到41%；由吸附热力学模型可以得出结论：温度越低吸附效果越好；初始浓度增加，吸附效果降低。可用Langmuir吸附等温式来对粉煤灰吸附处理水中三氯苯酚的吸附规律进行较好地描述，其吸附热小于零，吸附为放热反应。本实验采用Bangham和Langmuir模式拟合吸附动力学与吸附热力学，有吸附动力学和吸附热力学模型可以判断粉煤灰吸附三氯苯酚的吸附速度的控制为内膜扩散。87118

ABSTRACT Using fly ash adsorption treatment of wastewater containing trichlorophenol research has caused wide attention。 Using fly ash disposal of waste water containing trichlorophenol cheap and removal rate can reach the emission standard。 This experiment adopts the adsorption of fly ash processing waste water containing trichlorophenol。 Experimental research on the dosing quantity, pH value of fly ash on the effect of fly ash adsorption trichlorophenol, the influence of reaction time, reaction temperature on the adsorption effect, and the influence of super living with fly ash on the adsorption of microwave trichlorophenol absorption of the composite, the determination of the adsorption isotherm under different temperature, and the adsorption kinetics and thermodynamics model are discussed in this paper。 The experimental results show that the optimal dosing quantity of fly ash is 80 mg; Optimal pH 7。 Reflect the adsorption equilibrium time is approximately 50 min, trichlorophenol removal rate reached 41%; Conducive to the adsorption at low temperature; Initial concentration, reduce adsorption effect。 Trichlorophenol adsorption in water law of fly ash can be used to better describe the Langmuir adsorption isotherm, its adsorption heat is less than zero, the adsorption of exothermic reaction。 Adsorption kinetics with Bangham and Langmuir model fitting, and the adsorption rate is controlled by internal diffusion process 。
