摘要
在综合考虑淀山湖千墩浦河口区域的地形、水文、水质、植被、航道等环境因素和工程实施总体目标的基础上,从工程选址、浮床结构、浮床植物筛选、浮床布局以及浮床系统保护等方面开展了生态浮床试验工程的研究与设计,并通过实践进行了效果验证,为在淀山湖大规模开展浮床工程建设积累了技术参数和运行经验。工程运行一年来的情况表明,浮床技术可有效削减富营养化水体中的COD、TN、氨氮和TP等营养物质,为后续的生态修复工程奠定良好基础;选择的浮床植物较好地适应了淀山湖水体营养状况,植物收获量达到和超过了考核目标;设计的"消浪排+防浪围隔"防护系统结构可有效抵御风浪和船行波的影响,围隔对波浪能的消减率可达39%。
Based on the comprehensive consideration of environmental factors including topography, hydrology, water quality, vegetation, waterway in the Qiandunpu estuary region and the project overall objective, the research and design of ecological floating bed pilot project were conducted in terms of project site selection, floating bed structure, plant selection, floating bed layout and floating bed protec- tion. The effect validation was performed through experience, and some technical data and operational experience were accumulated for large-scale floating bed project construction at Dianshan Lake. The re- suits of one-year operation show that the ecological floating bed technology can effectively reduce chemical oxygen demand, total nitrogen, ammonia nitrogen, total phosphorus in the eutrophic water body and ben- efit the subsequent ecological restoration. The aquatic plants in the ecological floating bed adapt the water nutrition level. The plant yield achieves and even exceeds the exam objectives. The anti-wave protection system designed as bamboo raft and rubber enclosure can effectively resist the impact of the storms and ship waves, and the wave energy can be reduced by 39%.
