摘要
中国江河湖库水体污染状况严重,且难以用传统的物理、化学方法进行修复,生态浮岛作为一种生物-生态修复技术以其操作简单、处理效果好以及环境风险低等优点在河湖污染修复中得到大家的广泛关注。以发展进程为线索,作用主体和动力模式为依据对生态浮岛技术进行归纳总结,分类阐述了传统生态浮岛、组合型浮岛和微动力浮岛的研究及应用情况。展望了今后的研究方向,包括创建适于硝化菌和反硝化菌生长的微环境,加强生态系统交互作用和引入太阳能装置等。以期对生态浮岛在河湖污染修复中的研究及应用提供参考。
Rivers and lakes in China were seriously polluted and they are technically difficult to remediate by using traditional physical and chemical methods .Ecological floating island , a biotical-ecological restoration technology has drawn great public at-tention thanks to its simple operation, good treatment effect and low environmental risks.The research and application situation of the traditional ecological floating island(AFI), combined AFI and micro power AFI are reviewed in this paper,which are classi-fied according to the developing history, main body effect and power mode.The future research directions were analyzed, inclu-ding the creation of suitable growth environment for nitrobacteria and denitrifying bacteria , strengthening the interaction inside the ecological system and introducing solar devices, etc.The purpose is to provide references for the study and application of the eco-logical floating island in the dystrophicationrestoration.
