  • 摘要: 为研究潜流人工湿地对毒死蜱、BPA及4-NP的去除效果,选取宽叶香蒲、芦苇、花叶香蒲及小香蒲4种湿地植物,通过SPE-HPLC测定进出水中3种污染物的浓度,计算4种植物潜流人工湿地对3种污染物的去除效率。结果表明,水力停留时间3 d,4组植物对毒死蜱、BPA和4-NP去除率均高于60%,各植物组对毒死蜱和4-NP的去除效果之间无显著性差异,宽叶香蒲对BPA的去除率为82.66%,显著高于其余3种植物组62.96%~69.63%。在静态条件下,毒死蜱、BPA和4-NP在模拟系统内降解过程符合一级降解动力学方程,降解方程分别为:c=124.63exp(-t/25.393)+3.7618 ①,c=316.61exp(-t/34.955)+0.56475 ②,c=168.91exp(-t/17.061)+12.133 ③(c,剩余浓度,μg/L;t,停留时间,h),半衰期分别为18、21和11 h。
