摘　　要：以矿化垃圾反应床生物出水为研究对象,探讨了不同吸附树脂对COD的去除效果.研究结果表明,在矿化垃圾反应床出水COD浓度为236.77 mg/L的条件下,四种吸附树脂包括AG-MP-1,XAD-8,XAD-4和NDA-150对COD的去除率分别为29.8%、25.5%、55.2%、和69.0%.吸附效果最好的NDA-150树脂,在20 h可使尾水COD浓度小于100 mg/L.不同温度对NDA-150树脂的吸附性能影响不大.树脂吸附符合拟二级反应,主要是扩散传质过程.Different adsorption resins were investigated for their potential application in treating leaehate ef- fluent from aged refuse biofilter. At the COD concentration of 236.77 mg/L, four adsorbent resins including AG -MP-1, XAD--8, XAD-4 and NDA-150, could remove COD of 29.8%, 25.5%, 55.2%, and 69.0%, respectively. Among the four resins, NDA-150 presented the best adsorption behavior, leading to a COD of leachate lower than 100 mg/L in 20 h. Temperature may not influence adsorption effect of NDA-150 signifi- cantly. Pseudo-second-order model successfully fits the kinetic adsorption, and the adsorption is controlled by the diffusion process.
