| 摘 要： | 引清促活、引水改善城市湖泊水质是一种见效较快的方法.以往多采用集中引水的方法,因城市湖泊湖岸曲折多弯,集中引排方法常存在一些死水区;死水区中的水体得不到有效更新,影响了引水改善湖泊水质的总体效果.为此,提出了集中与分布式引水相结合的方法;讨论了分布式引水点位置及引水流量、引水点水流出水设施、出水方向、出水流速、出水长度...

| Abstract: | Flow augmentation and water renewal via diverting clean water into an urban lake is an effective means for improving lake water quality.However,concentrated water diverting that is usually employed has the disadvantage of creating dead water areas due to the bays in the lake,which reduces the effectiveness of water quality improvement.To solve this problem,a procedure of concentrated water diverting at relatively higher flow-rate combined with dis-tributed one at relatively lower flow-rate was presented in ... |
