摘要
循环水养殖模式(RAS)是目前国内水产工厂化养殖推行的节能、环保、高产模式,但由于养殖者重生产、轻管理、不懂技术及技术不成熟等原因,使养殖区残饵粪便污染一直得不到很好的解决,成了RAS模式最核心的技术难题。通过探讨国内RAS模式发展现状及工艺中存在的问题,分析了RAS系统中残饵粪便成分及其污染危害,并针对其治理工艺和技术提出研究的思路。
The model of RAS is an energy-saving,environment-friendly and high-yield model for domestic aquaculture factorization at present.However,because the breeders who do not understand the technology or possess immature technology pay more attention to production,less management,so that the pollution of baits and feces in breeding areas have not been well resolved with the result that it has become a core technical problem of the RAS model.Based on the discussion of the present development situation of the domestic RAS model and the existing problems in the process,this paper analyzed the components of residual baits and feces and its pollution harm in the RAS system,and puts forward some ideas for further research aiming at its treatment process and technology.
