| 摘 要： | 基于水牛植物具有减缓和抑制水体富营养化、净化水质的作用,通过调控水生植物生物量,研究再生水回用于景观湖泊中水质恶化风险控制方法.结果表明,在直接回用再生水的景观湖泊中,随植物覆盖率由0增长到80%,水生植物能够降低94%的水体感官性污染,抑制92%的藻类滋生,实现92%NH_3-N和近70%TP的有效去除,延长2倍水体水质稳定时间.此外,综合比较景观湖泊经济及景观价值,55%植物覆盖率能有效降低水体富营养化风险,是一种再生水回用于景观湖泊植物调控水质的有效布设方式.

| Abstract: | Hydrophytes can effectively restrain water eutrophication and lower water pollution.Through adjusting surface coverage by hydrophytes in landscape lakes which use reclaimed wastewater directly, technology to lower deterioration risk for landscape water body was investigated. Data showed that in landscape lakes using reclaimed water directly, when surface coverage of hydrophytes increased from 0% to 80%, hydrophytes can significantly reduce 94% of aesthetic pollution, restrain over 92% of total algae, remove 92% of ammonia and about 70% of TP, respectively, and double water quality stabilization. In addition, comprehensively considering economic and aesthetic value of landscape lakes, to keep surface coverage by hydrophytes to 55%, can effectively lower eutrophication risk. This is an effective measurement for stabilizing landscape water body. |
