摘要：超细纤维具有的高吸水、高排水和高比表面积等特性，在新型过滤材料方面逐渐得到应用。使用高吸附、易复净的超细纤维织物作为滤料或结扎成超细纤维球来处理高氨氮、高悬浮物的水产养殖废水，比使用黄沙、砾石等天然滤料可大幅减少过滤系统的重量和体积，且易于拆卸、整合；超细纤维织物也可以作为基质，通过与水生植物和微生物组成复合生物滤器，是养殖水体循环利用，减少资源消耗。通过采用不同结构和密度的超细纤维构成的滤布、纤维球和以其为基质的复合生物滤器来过滤吸收养殖废水中的悬浮有机物、氨氮，在水产养殖水处理中具有良好的科研价值和广泛的应用前景。

Abstract: Microfiber is a new material gradually used in aquaculture for its characters: highly water-absorbed, fast dry, high specific area. It is practial to use the microfiber-textile to deal with the high suspended substance (SS) and amonia in the wasted aquaculture water. It is slimmer and lighter than gravel and quartz sand and also easy to be assembled. Microfiber can also be used to be the base-material in combining biofilter. The microbiber-based combining biofilter can use the maximum organism in water and transform it to be the aquaculture products. With the researches on the abilities of different microfiber textiles and fiber-ball to be used as filterstuff and the microbiber-based combining biofilter, we can improve the aquaculture water recycle and reduce the exhaust carbon dioxide in a more effective way.

Key words: Microfiber; water treatment; filter material; combining biofilter
