| 摘 要： | 采用围隔浮床系统,研究了冬、春季节陆生黑麦草(Lolium multiflorm)对畜禽养殖富营养水体中主要营养元素氮的净化效应及动态过程。结果表明:浮床黑麦草在试验小区中生长良好,浮床黑麦草系统对富营养水体中的总氮具有明显的净化效果。当覆盖率分别为15%,30%,45%和60%时,水体中的TN分别减少了5.6mg/L,6.54 mg/L,5.42 mg/L及3.36 mg/L。覆盖率为30%时,TN的去除率最高,达到74.91%。对浮床黑麦草去除水体总氮的动态过程拟合表明,符合三次方程曲线。 |

| Abstract: | TN removal characters and dynamics processes of eutrophic water by Lolium multiflorum planted on floating-bed were studied in winter and spring seasons.The results showed that Lolium multiflorum could grow well on floating-bed.Lolium multiflorum had a good effect on the removal TN from eutrophic water body.When the floating-bed coverage rates were set up at 15%,30%,45% and 60%,the concentration of total nitrogen were reduced 5.6,6.54,5.42 and 3.36mg/L respectively.The removal rate of TN by Lolium multiflorum was 74.91% when the floating bed coverage rate was 30%.The fitting method of dynamics processes of removing TN by Lolium multiflorum showed it accord with cubic curve. |
