| 摘 要： | 滇池及其入湖河道深层水体严重缺氧,水生生态系统近于彻底崩溃,进一步加剧了富营养化。人工辅助增氧因不会引入新污染物、新物种等优点,环境友好,是治理富营养化的重要途径之一。滇池面积巨大,入湖河道、管道复杂,富营养化严重,需要大规模的人工辅助增氧才可能获得良好的治理效果,而目前国内外尚未有大型污染湖泊大规模人工辅助增氧的经验可资借鉴。结合昆明旅游城市及人居环境建设的要求,为尽量减少或分散增氧投资,发挥综合效益,提出了一系列城市排水管道增氧、排放口增氧、穿城河道增氧及滇池增氧的具体途径与措施。

| Abstract: | The pollution of Lake Dianchi and its tributaries in the last decades has led to serious hypoxia or even anoxia in deep water levels,and the aquatic ecosystems have nearly collapsed completely,resulting in further exacerbating eutrophication.Because the artificial auxiliary aerobics has the advantage of introducing no new pollutants and new species,it is one of the most environment-friendly methods to control eutrophication of an ecosystem.Due to large-area serious eutrophication,complex tributaries and pip... |
