摘要： 以水源地除藻围隔为研究对象,详细调研了围隔对藻的过滤拦截效果.通过实验模拟探讨了影响围隔拦截效果的主要因素,以及围隔过滤拦截过程中的污染机理,研究了围隔的清洁循环使用性能.通过实地布设除藻围隔,比较了围隔过滤前后藻总量的变化,验证了除藻围隔的实际除藻能力.实验结果表明:围隔对藻有一定的拦截作用,围隔前后的藻总量存在较大差异;在0$\sim$0.03 m$^{3}$/(m$^{2}\cdot$s)范围内,过水通量越大,除藻效率越低;超出0.03 m$^{3}$/(m$^{2}\cdot$s)时,藻去除率低于5%;在10$\sim$60 NTU范围内,浑浊度越高,除藻效果越好;叶绿素a的质量浓度对围隔过滤拦截效果的影响不显著;围隔过滤拦截污染的机制主要为滤饼过滤模型,具有较好的清洁循环使用能力.

Abstract: The algal barrier at the water source was considered as the research object. The filtering and interception effects of the barrier on algae were investigated in details. It was explored that the main factors affecting the pollution interception effects of the barrier and the mechanism of the filtering and interception processes of the barrier through experimental simulation. The cleaning and recycling performances of the barrier were studied. By setting up an algal barrier in the field, the total amount of change was compared in algae before and after filtering by the barrier, and the actual algae removal ability of the barrier was verified. The experimental results showed that the water source containment had an interception effect on the algae in the water. There was a large difference in the total amount of algae before and after the containment. In the range of 0$\sim$0.03 m$^3$/(m$^2\cdot$s), the higher the through-water flux, the lower was the algae removal efficiency. Beyond 0.03 m$^3$/(m$^2\cdot$s), the removal rate was less than 5%. In the 10$\sim$60 NTU range, the higher the turbidity, the better was the algae removal effect. Chlorophyll a concentration did not have a significant effect on the perimeter filter interception. The filter cake filtration model was the main pollution interception mechanism in perimeter filtration and had good cleaning and recycling abilities.

Key words: water source reservoir, enclosure, interception efficiency, chlorophyll a
