摘要：

通过建立人工瀑布与湿地联合运行工程对景观水进行修复.采用局部循环净化方式，考察该工程对景观水水质的净化与维护效果.结果表明，湿地区域灯心草对氮的吸收及大量微生物的转化作用，使NH⁺₄-N浓度始终不高于0.5 mg/L，TP浓度亦低于瀑布角水和水面落点两样点.各样点C/N值由初始时的6~7升高到12~16，湿地样点C/N值始终保持较高水平.湿地生态系统好氧与厌氧环境的交替可有效去除系统中的氮素.N/P值由初始的30~31下降到3左右.人工瀑布充氧及湿地生态系统的协同调节作用可抑制水体过酸或过碱.进入湿地区后，NH⁺₄-N去除率由3.4%~10.4%增加到24.6%~44.2%，TP去除率由0.5%~25.0%增加到71.0%.植物与微生物的联合净化是去除污染物的有效途径.

Abstract:

Waterfall and wetland were used to remedy landscaping water. Partial recycling was carried out to maintain water quality. The result showed that aerobic microbes in constructed wetland reduce the concentration of NH⁺₄-N to 0.5 mg·L^-1, and the concentration of TP was lower than the other two sites. C/N of each site rose from the initial 6~7 to 12~16. Alternative aerobic and anaerobic area in wetland system effectively removed nitrogen. N/P fell from 30~31 to 3. Waterfall and wetland maintained the pH value of water. Removal rate of NH⁺₄-N increased from 3.4%~10.4% to 24.6%~44.2%, and removal rate of TP increased from 0.5%~25.0% to 71.0%. Apart from oxygen supplying, combination of vegetable and microbes is also needed to remove contamination in landscaping water.
