| 摘 要： | 研究了风车划（Cyerus alternifolius）的生长特性和对生活污水的净化效果。风车草全年保持生长，即使在冬天仍能维持一定的生长速率。风车草在生活污水中培养10d后，污水中TN、TP、COD和BOD的去除率分别达到91％、92％、70％和73％，其中风车草对N、P的吸收量分别占净化量的55％和53％。种植风车草的潜流型人工湿地对TN、TP、COD和BOD的去除率分别为64％、47％、74％和74％，与不种植物的人工湿地相比，TN、TP、COD和BOD的去除率分别提高了28％、19％、14％和13％。图2表3参12

| Abstract: | Growth characteristics and purifying efficiency of Cyperus alternifolius to domestic sewage were studied. C. alternifolius could grow throughout a year and keep certain growth rate even in the winter. After C. alternifolius were cultivated in domestic sewage for 10 d, the removal rates of TN,TP,COD and BOD were 91%,92%,70% and 73%, respectively; while the amounts of uptake to TN and TP by plant accounted for 55% and 53% of the purification amounts, respectively. The removal rates of TN,TP,COD and BOD in the subsurface flow constructed wetland with C. alternifolius were 64%, 47%, 74% and 74%, respectively; compared with unplanted system, the removal rates of TN,TP,COD and BOD raised 28%,19%,14% and 13%, respectively.
