摘要
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.
Abstract
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 manage-ment 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 influen-cing 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 environ-mental friendliness,this article aims to provide a theoretical basis and practical guidance for the further optimiza-tion and application of RAS technology,with the expectation of promoting the sustainable development of recircu-lating water aquaculture technology.
