| 摘 要： | 该文对基于复合垂直流人工湿地(IVCW)的循环水养殖系统的净化效率、养殖效果和系统优化设计进行了研究.结果表明,在420 mm/d的水力负荷下,湿地可有效地去除循环水中的总悬浮物(去除率85%)、CODCr(去除率50%)、BOD5(去除率44%)、总氨氮(去除率53%)、亚硝酸盐(去除率83%)和硝酸盐(去除率54%),能够满足养殖用水的要求,整个试验期间系统实现了零污水排放.经过5个月的养殖,成功地将斑点叉尾鲴(Ictalurus punctatus)鱼苗(1.8 cm,0.08g)培育成鱼种(15.9 cm,33.9 g),成活率达到92.6%.在养殖容量、病害控制、成活率以及鱼体生长速度等方面均优于常规池塘养殖模式.建立了一个预测湿地与养殖池塘面积配比的数学模型,为实际应用和优化设计提供依据.

| Abstract: | This study investigated the purifying efficiency, culture performance and design optimization of a recirculating aquaculture system (RAS) combined with integrated vertical-flow constructed wetland (IVCW). The results showed that the IVCW effectively removed total suspended solids (85%), chemical oxygen demand (50%), five-day biochemical oxygen demand (44%), total ammonia (53%), nitrite (83%) and nitrate (54%) from the aquaculture wastewater at a hydraulic loading rate (HLR) of 420mm/d. The channel catfish (Ictalurus punctatus) were bred up from fry (1.8 cm, 0.08 g) to juvenile (15.9 cm, 33.9 g) after five months. The survival ratio was 92.6%. A simple model for estimating the area ratios of wetlands to culture ponds was developed to optimize the design of the RAS combined with IVCW. |
