工厂化循环水养殖系统 (RAS)作为一种先进的水产养殖技术,通过精细化的系统管理和应用前沿工程技术,实现了水资源的高效利用和饲料消耗的显著降低。尽管如此,养殖过程中产生的代谢废物积累,可能诱发严重的异味问题,对养殖环境的稳定性和生产效率构成潜在威胁。本文综述了RAS系统中异味产生的机理,并深入分析两种关键异味物质—土臭素 (GSM)和2-甲基异莰醇 (2-MIB)的来源及其影响因素。此外,本文系统性地回顾了RAS系统中异味去除技术的最新研究进展,涵盖了生物、物理和化学处理等多种方法。通过全面比较这些技术在效率、成本、操作以及环境友好性等方面的优劣,为RAS技术的进一步优化和应用提供理论依据和实践指导,以期促进循环水养殖技术的可持续发展。
Recirculating Aquaculture Systems (RAS), as an advanced aquaculture technology, achieve efficient utilization of water resources and a significant reduction in feed consumption through meticulous system management and the application of cutting-edge engineering techniques. Despite these advancements, the accumulation of metabolic waste generated during the cultivation process may trigger severe odor issues, posing a potential threat to the stability of the cultivation environment and production efficiency. This review comprehensively examines the mechanisms of odor generation in RAS systems and provides an in-depth analysis of the origins and influencing factors of two key odor-causing substances-geosmin (GSM) and 2-methylisoborneol (2-MIB). Furthermore, this paper systematically reviews the latest research progress in odor removal technologies within RAS systems, covering a variety of methods including biological, physical, and chemical treatments. By thoroughly comparing the advantages and disadvantages of these technologies in terms of efficiency, cost, ease of operation and environmental friendliness, this article aims to provide a theoretical basis and practical guidance for the further optimization and application of RAS technology, with the expectation of promoting the sustainable development of recirculating water aquaculture technology.
