前置库拦藻帘在金鸡湖水环境改善中的研究应用

Study on Application of the Performance of Algae Intercept Curtain Ahead in Water Environment Improvement for Jinji Lake

在蓝藻密度较高、水华较易发生的湖泊中,设置拦藻帘,是对蓝藻、漂浮物等进行拦截及初步过滤,去除大部分藻类及部分细颗粒悬浮物的重要手段。为了使拦藻帘既能发挥拦截作用,又尽量不降低透水性能,需要通过综合测试,调整其相关参数,研究不同参数下拦藻帘的拦截效果、降浊效果和透水能力,综合考虑确定其相关参数。本文以金鸡湖调水引流工程为例,针对小西湖的藻类特性,通过相关参数的设定,研究相应的拦截性能和透水性能,从而确定拟采用拦藻帘的设计参数,为工程设计提供技术支撑,也为其他类似项目提供参考。

In the lakes in which blue-green algae is relatively high and algal bloom easily occurs,installing algae intercept curtain is an important measure to stop,filtrate and clear most blue-green algae,some floater and suspended solids.In order to make the algae intercept curtain not only play a role stopping,but also not decrease permeability as far as possible,it is necessary to adjust relative factors,to study the effect stopping,turbidity reducing effect and permeability of algae intercept curtain by means of comprehensive testing,comprehensively to consider and determine relative factors.In this paper,the authors,taking the water diversion project of Jinji Lake as an example,in view of algae characteristics of Xiaoxi Lake,through relative factors setting,studied relative stopping performance and permeability,determined the design parameters intended to be adopted for algae intercept curtain,provided technical support for the project design,also provided certain reference for other similar projects.
