摘　　要：河湖富营养化是环境问题,也是民生问题,同时关系到社会与经济的稳定发展。针对日趋严重的富营养化问题,课题组研发出一种景观式新型微纳米增氧生物浮岛技术,并将其应用于开封市包公湖以测试其治理效果。经过为期31 d的测试,富营养化水体的溶解氧、透明度、总氮、总磷及叶绿素a指标均有较大改善,底泥厚度逐渐减小。溶解氧、透明度的指标增长率分别为150%、192%,底泥厚度、生物量、总氮、总磷、叶绿素a、高锰酸盐指数的指标削减率分别为42. 9%、98. 2%、90. 2%、95. 1%、95. 7%、70. 9%。由水体综合营养状态指数的计算分析结果可知,水体经过处理后由重度富营养化状态变为轻度富营养化状态。研究结果可为河湖富营养化治理提供数据参考和技术支撑。Eutrophication of rivers and lakes is not only an environmental issue but also a livelihood issue. At the same time,it is related to the stable development of society and economy. In response to the increasingly serious eutrophication problem, the research group developed a new technology called landscape-type micro-nano aerobic biological floating island technology and applied to Baogong Lake in Kaifeng city. After 31 days＇ testing, the indicators such as transparency, dissolved oxygen, total nitrogen, total phosphorus and chlorophyll-a in the eutrophic water had been greatly improved, and the sediment thickness had gradually decreased. The DO and SD growth rates were 150% and 192%. The reduction rates ofTN, TP, Chl-a, and CODMr,were 90.2%, 95. 1%, 95.7%, and 70.9%. Through calculation and analysis of the water bod＇s comprehensive nutritional status index, the water body is reduced to a light eutrophic state from severe eutrophication after being treated. The paper will provide some data reference and technical support for eutrophication treatment of rivers and lakes.
