| 摘 要： | 过去采用美人蕉等浮床来净化水质报道较多,而采用原位围隔高羊茅草坪浮床来净化重污染河道水体,目前尚未见有报道.本文研究了不同高羊茅草坪浮床覆盖率对冬季重污染河道水体的净化能力,以期确定其最佳覆盖密度.试验结果表明,高羊茅浮床对富营养化水体中的氮、磷、COD等均具有极强的去除能力,并能有效提高水体透明度.这为冬季重污染河道水体水质改善的示范工程提供了可靠的科学依据.

| Abstract: | Canna generalis was often used to purify polluted river by floating bed,while the floating bed of Festuca arudinaces was less used.The purification of seriously polluted river in winter by Festuca arudinaces of different floating-bed coverage rates was carried out to find the best coverage rates in heavy polluted river,Suzhou City.The results showed that Festuca arudinaces had a high ability to remove nitrogen,phosphorus and COD in eutrophicated water,and the water clarity(SD)was raised effectively.Future engineering for improving water quality of heavy polluted river in winter would be favorable through the use of floating bed of Festuca arudinaces. |
