摘要: 通过分析整理国内外相关研究资料,阐述整流幕的研究进展及其在国内水库的应用前景。结合水温分层、异重流等理论知识,分析应用整流幕的水动力背景,进而深入探究整流幕的控藻机理;整流幕应用水动力学原理,使能量交换、水团混合、水体分层等过程发生变化,进而改变影响藻类生长及演替的主要生境要素,如光照、水温和营养盐等,从而防控水华。应用整流幕前,通常将库区划分为上游、中游及下游3段。基于库区内不同河段的水流特性,并结合对整流幕类型及适用条件的分析,可以有针对性地开展整流幕方案以达到更好的效果。研究结果可为水库水生态环境保护提供参考。

Abstract: The research progress and application prospects of curtain weirs were expounded in this study by analyzing the related research in China and abroad. The algae control mechanism of curtain weirs was explored in the light of hydrodynamics, water temperature stratification, density currents and some other theories. Curtain weirs change the processes of energy exchange, water mixing and stratification using the hydrodynamic principle, and then change the light, water temperature, nutrients, and other main habitat factors that affect the growth and succession of algae, and finally control algal blooms. Before the installation of curtain weirs, the reservoir area is often divided into three segments, namely, the upstream, the midstream, and the downstream. In view of the flow characteristics of different segments, the application scope and types of curtain weirs should be considered before installation in order to achieve a better result. The present study could provide a reference for reservoir water environment protection.

Key words: curtain weir, algal blooms, hydrodynamics, water temperature stratification, density currents, reservoir
