城市景观水体生态修复技术研究与运用——以厦门五缘湾湿地公园为例

Technology research and application of ecological restoration in urban landscape water——A case study of Xiamen Wuyuan Wetland Park water system's treatment

在逐步完善截污、清淤及生态护坡等工程的同时,综合运用底泥矿化、微生物净化技术,结合构建人工浮岛、生物栅、定点增氧推流、复合滤床循环、人工湿地等净水措施,对厦门五缘湾湿地公园水系进行探索性生态修复试验。治理后NH3-N、TN、TP及COD等主要水质指标均达到国家地表水V类标准要求,湿地公园水质和生态环境质量得到明显改善。该技术体系研究与运用为城市景观水生态修复和维护运营管理提供了一整套实用可推广技术。

At the same time of improving the sewage interception,siltting displacement and ecological embankment,the paper had a exploratory test on ecological restoration of Xiamen Wuyuan Wetland Park by using bottom sediment mineralization,microbial purification technology,and the water purification measures,such as the floating island,the bio grid,the plug-flow fixed oxygen,the cycle of composite filter bed,the artificial wetland etc.The results showed that the water quality and ecological environment of water of Wetland Park had been improved observably.And the mainly index of water quality had reached the GB3838-88 V water standard.The technology research and application of this technical system provided a set of practical techniques for the ecological restoration in urban landscape water as well for the management and the maintenance.
