- 摘要:
- 以2种鸢尾属植物为试材，采用生物滞留柱模拟生物滞留池的试验方法，研究了2种供试植物对生物滞留柱滞水能力、渗水能力、净水能力的影响，以期为生物滞留池功能植物选择提供参考。结果表明：种植马蔺、鸢尾及未种植植物的对照，3种生物滞留柱滞留水量分别占进水量的60.09%、46.74%、24.78%；生物滞留柱从开始进水至开始出水经历时间不同，马蔺进水40 min后开始出水，鸢尾进水34 min后开始出水，而对照进水27 min开始出水，明显早于前二者；平均出水速度为对照9.22 mL·min-1、鸢尾8.08 mL·min-1、马蔺6.80 mL·min-1。供试植物显著提高了生物滞留柱的滞水能力，与未种植植物的生物滞留柱相比，2种鸢尾的生物滞留柱出水时间晚、水力停留时间长、滞留水量大、出水速度慢；其中马蔺的效果优于鸢尾。马蔺入渗速率为250 mm·h-1，鸢尾为125 mm·h-1，入渗性良好，对照为57.69 mm·h-1，入渗性较弱。供试植物显著提高了生物滞留柱的渗水能力，种植马蔺的生物滞留柱渗水能力强。对照、鸢尾、马蔺总磷去除率分别为-217.82%、-185.26%和-50.38%，氨氮去除率分别为-19.43%、4.54%和16.77%，悬浮物去除率分别为60.08%、77.12%和85.06%。供试植物不同程度提高了生物滞留柱的净水能力，其中马蔺的效果优于鸢尾。生物滞留柱对颗粒状的污染物去除效果较好，而对溶解态的污染物有一定的输出。
- Abstract:
- Two species of Iris plants were used as test materials,adopted simulated bioretention with biological detention column experimental methods,the water retention capacity,water seepage capacity and water purification capacity of different biological detention column with different plants were studied,in order to select plants used for biorentention.The results showed that the retention water of Iris lactea Pall.var.chinensis,Iris tectorum Maxim.,and control respectively accounted for 60.09%,46.74% and 24.78% of inflow.Inlet and outlet water interval of biological detention column were different,Iris lactea Pall.var.chinensis was 40 minutes,Iris tectorum Maxim.was 34 minutes,and control was 27 minutes.The average outflow speed of control was 9.22 mL·min-1,Iris tectorum Maxim. was 8.08 mL·min-1,and Iris lactea Pall.var.chinensis was 6.80 mL·min-1.Plants significantly improved the water retention capacity of biological detention column,compared with the biological detention column without plants,biological detention column with pants had later outflow time,longer hydraulic retention time,more water retention,slower outflow speed；compared with the biological retention column of Iris tectorum Maxim.,the biological retention column of Iris lactea Pall.var.chinensis had later outlet time,longer hydraulic retention time,more water retention,slower outflow speed,and the water retention capacity was stronger.The infiltration rate of the Iris lactea Pall.var.chinensis was 250 mm·h-1,the Iris tectorum Maxim.was 125 mm·h-1,the penetrability was good,the control was 57.69 mm·h-1,and the penetrability was weak.The plants significantly improved the water seepage capacity of the biological retention column,and compared with the biological retention column of Iris tectorum Maxim.,the water seepage capacity of the biological retention column of Iris lactea Pall.var.chinensis was stronger.The total phosphorus removal rate of control was -217.82%,Iris tectorum Maxim.was -185.26%,Iris lactea Pall.var.chinensis was -50.38%,ammonia nitrogen removal rate of control was -19.43%,Iris tectorum Maxim.was 4.54%,Iris lactea Pall.var.chinensis was 16.77%,and the suspension rate of control was 60.08%,Iris tectorum Maxim.was 77.12% and Iris lactea Pall.var.chinensis was 85.06%.The plants significantly improved the water purification capacity of the biological retention column,and compared with the biological retention column of Iris tectorum Maxim.,the biological retention column of Iris lactea Pall.var.chinensis was stronger.The biological retention column had a good effect on the removal of granular pollutants,and there were certain output of the dissolved pollutants.
