摘要
通过综合利用底泥疏浚、造流曝气及水生生态系统修复等技术对上海古猗园内的富营养化水体进行治理,结果显示此项综合技术对园林景观水体具有良好的污染物去除效果,对TN、NH_3-N和TP的去除率分别达到48.6%、95.8%和75.0%,园内水体水质、生态环境、景观效果等明显改善,具备了较强的自净能力。
In this study, the comprehensive ecological technologies including sediment dredging, river flow aeration and aquatic ecosystem restoration were used to improve the water quality in Shanghai Guyi garden. The results showed that the comprehensive ecological technology exerted effective perform- ance on restoration of landscape water. The removal efficiencies of TN, NH3 - N and TP respectively reached 48.6% , 95.8% and 75.0%. The water quality, ecological environment and landscape effect have been significantly improved so that the water is capable of effective self-purification.
