摘要
在很多湖泊、航道、江河入海口、近海海面、水电站的水面都集聚了以水葫芦、竹子、航运废弃物、生活垃圾等漂浮物,形成了集结,污染了环境,并影响航运,使水电站直接减小水头出力,减少了效益。根据对国内污染较严重的水电站以及清污难度较大的水电站的清污经历和对中国清污状况的调查了解,分析了中国目前的清污状况,对应采取的措施和应采用的清污机械,提出了行之有效的解决方案。
Floating debris, such as water hyacinth, bamboo, trashes left by navigation and living rubbish, is concentrated in many lakes, navigation channels, sea entrances and coastal waters, as well as on the surface of hydropower station reservoirs, which seriously pollutes the environment and influences the navigation, directly reduces the water head of hydropowcr stations and their benefits. Based on the investigation of seriously - polluted hydropower stations and the difficult trash - cleaning practice in some hydropower stations, this paper analyzes the trash - cleaning status of power stations in China and puts forward effective solutions on the preventive measures and raking equipment.
