| 摘 要： | 选用鸢尾、酸模、兰草、葱兰这4种陆生植物构建垂直流人工湿地并处理生活污水,考察了水力停留时间、水力负荷、温度以及湿地植物种类对处理效果的影响.结果表明:在较长水力停留时间(24 h左右)、较低水力负荷(0.3 m/d)条件下,湿地系统对污染物的去除率较高;随着温度的升高,湿地系统的除污效果提高;湿地中植物的长势好于自然环境中的,其中酸模的净化能力最强,其生长成熟时对氨氮、总磷的去除率稳定在95%左右,对COD的去除率在60%左右.

| Abstract: | A vertical flow constructed wetland was built with 4 terrestrial plants of iris,garden sorrel,bluegrass,Zephyranthes,and used to treat domestic sewage.The influence of hydraulic retention time(HRT),hydraulic loading rate(HLR),temperature and wetland plant species on the treatment effect was investigated.The results show that under conditions of longer HRT(about 24 h) and lower HLR(0.3 m/d),high removal rates of pollutants can be achieved.With increasing temperature,the treatment effect is improved.The plant... |
