潮白河流域人工复合土层系统去除甲氧苄氨嘧啶的模拟研究

基于潮白河流域再生水的场地回灌,为提高抗生素甲氧苄氨嘧啶(TMP)的去除率,降低其进入地下水的风险,选用价格低廉对TMP有高效去除性能的黏土陶粒作为吸附剂,构建去除TMP的人工复合土柱。吸附实验研究结果显示黏土陶粒对TMP吸附容量达到151.824μg/g,具有去除再生水中TMP能力;TMP在黏土陶粒解吸过程中存在解吸滞后性的现象。柱实验研究结果表明此人工复合土柱能够有效地去除再生水中TMP,去除率高于95%,其去除机制主要是吸附与生物降解协同作用。本研究建立的人工复合土层系统能有效地去除再生水中TMP,对实际场地回灌工程具有指导性作用。...

Based on the reclaimed water recharge of Chaobai River, clay ceramsites were chosen as adsorbent in this study, which has the character of low price and high adsorption capacity of trimethoprim (TMP), in order to reduce the amount of TMP entering into environment. The adsorption capacity of TMP reached 151. 824 μg/g, which has the ability of removing TMP from reclaimed water. Desorption experimental results showed that the desorption hysteresis of TMP in clay ceramsites was d
