本文以循环水养殖模式工艺流程为主线，结合近年养殖模式科学研究和国内循环水养殖产业发展现状，围绕水质处理和应用，分别对系统中的大颗粒物滤除、臭氧消毒、气浮综合处理、生物滤池、紫外线杀菌、pH值调节等水质处理环节进行了综合分析和探讨，为今后创建适合中国国情的高端循环水养殖模式、推进循环水处理技术的精准化和实用化提供参考。

Based on recirculating aquaculture mode technological process, combined with nearly years' aquaculture mode scientific research and industrial development, focused on water treatment and application, this paper summarized and discussed big particle filter, ozone disinfection, gas floating comprehensive treatment, biological filter, ultraviolet radiation sterilization, pH adjustment and other aspects of water conditioning respectively, which can provide corresponding reference for impelling the precision and practical water treatment process and establishing the high-end recirculating aquaculture mode for the situation of China in the future.
