摘要: 传统水产养殖模式易造成水体污染、水资源浪费等问题,影响鱼类生长。为达到健康养殖的目的,池塘循环水养殖系统在循环经济理念指导下,通过利用动力流水净化与生物修复技术,采取建立人工湿地等措施净化水体,形成一套可持续发展模式。本研究综述了该系统的3种主要模式的构建及其水质净化效果,分析该系统运行中出现的主要问题。现有研究表明,不同模式下对TN、TP、NH4+-N、CODMn、NO2--N等水质指标平均去除率基本维持在60%。同时,分析了系统中养殖池塘与净化单元面积配比关系的计算、净化单元中基质与植物以及PH、温度等对净化效果的影响。本研究通过对这些研究的总结与讨论分析,将为深入对池塘循环水养殖系统的研究提供参考资料。

Abstract: The traditional aquaculture pattern can easily cause water pollution and waste of water resources. In order to reach the goal of healthy aquaculture, pond recirculating aquaculture system (PRAS) takes measures to purify water by using power flow purification and bioremediation techniques under the guidance of circular economy, such as establishing artificial wetland to form a sustainable development model. In this study, we summarized the construction of the three main models of PRAS and their effects on water purification, and analyzed the main problems in the operation of the system. The existing studies showed that the average removal rates of TN, TP, NH4+-N, CODMn, and NO2--N were basically maintained at 60%. Besides, we analyzed the factors such as the ratio of purification area to pond area as well as the effects of the substrate, plant, pH and temperature in the purification unit. This study can provide a reference for further in-depth research on PRAS.
