摘　　要：以长纤维束为滤料过滤海岛雨水,探索纤维滤料过滤雨水技术的可行性。结果表明,纤维滤料对雨水中的大颗粒悬浮物有显著的吸附截留作用;当滤速为20 m/h、进水浊度为5NTU时,经纤维滤料过滤的出水浊度在1 NTU左右,运行时间达80 h以上;滤速和进水浊度的增加对浊度的去除影响不大,但对过滤周期有影响。纤维束的孔隙分布使其具有良好的过滤效果,且无需投加絮凝剂,更适合雨水的高速、高效过滤。The feasibility of long fiber filter material for filtration of island rainwater was investigated. Theexperimental results showed that fiber filter material had obvious adsorption and rejection of large suspended matter in rainwater. When the filtration velocity was 20 m/h and influent turbidity was 5 NTU, the turbidity of effluent was about 1 NTU, and the operation period was over 80 h. Increasing of filtration velocity and influent turbidity had influence on the operation period, but had no evident effect on the turbidity removal efficiency. It was found that fiber bundle had favorable filtration effect due to the distribution of pore. Fiber filter could operate with high filtration velocity and high efficiency in rainwater purification without flocculant.
