在循环水工厂化水产养殖中,鱼类的排泄物、残饵、生物团等产生的悬浮物和固体物,增加了水体的浑浊度,堵塞了生物滤器,影响系统的性能和鱼类健康生长。本文根据我国现代渔业发展的趋势,结合国内外有关水产养殖水处理技术的研究成果与发展趋势,论述和分析了目前工厂化水产养殖中悬浮与固体物的物理、化学和生物处理技术及发展趋势,为研发新型水处理设备奠定基础。
In recirculating aquaculture, suspended solids derived from food remnants and fish feces have become a key factor seriously impacting on the growth and health of fish. The main water treatments including physical, chemical, biological techniques and the de-velopment trend of further research are summarized based on the trend of modem fisheries development, combined with research and development trend of the aquaculture water treatment technology. Based on the analysis, some new effective techniques which meet the needs of recirculating aquaculture system are discussed.
