摘要
生物浮床是一种有效的水质改善技术,既能有效去除水体中所含有的污染物,也可提高水面利用率、节约土地及技术成本。为此,文章基于生物浮床种植法设计可持续利用的淹没式组合生态浮床种植装置,利用复合材料制作浮板,并在种植篮中增加附着生物膜的填料,应用维纶丝作为人工水草制作材料,并通过排列方式调整,增大维纶丝悬挂密度进而提升生物膜的生长附着效果。而后通过实验分析法测定水质中的溶解性正磷酸盐、总磷、氨氮、总氮、高锰酸盐指数和色度六个指标,以此验证此种可持续利用生物浮床的水质改善效果。
Biological floating bed is an effective technology to improve water quality,which can not only effectively remove the pollutants contained in water,but also improve the utilization rate of water surface and save land and technical costs.For this reason,based on the biological floating bed planting method,a sustainable submerged combined ecological floating bed planting device is designed in this paper.the floating board is made of composite materials,and the filler attached to the biofilm is added to the planting basket.Vinylon filament is used as artificial aquatic plant material,and through the arrangement adjustment,the suspension density of vinylon filament is increased and the growth and adhesion effect of biofilm is improved.Then the six indexes of dissolved orthophosphate,total phosphorus,ammonia nitrogen,total nitrogen,permanganate index and chromaticity in water quality were determined by experimental analysis,in order to verify the water quality improvement effect of this kind of sustainable utilization biological floating bed.
