以大型观光植物美人蕉—砾石为基础的垂直流人工湿地对胡子鲇养殖水体进行净化处理和回流使用,在胡子鲇养殖中测定了水体主要水质指标的变化,表明人工湿地对养殖水体净化效果显著,养殖期间BOD5、COD、TN的平均去除率分别为81.77%、55.55%和65%,净化后水质部分符合渔业用水标准,可以循环利用。对照池水体由于BOD5、COD、TN得不到去除而持续增加,混浊度显著高于实验池,并出现水华。这种水体循环养殖模式具结构简单和易推广等优点。
The large-scale tourist plant canna-gravel-based vertical-flow constructed wetland was used to purify and recycle the bearded tapiriculture water. The changes of the main water quality indexes of the bearded tapir were measured, which showed that the wetland had a significant purifying effect on the aquaculture water, The average removal rates of BOD5, COD and TN during breeding were 81.77%, 55.55% and 65%, respectively. The purified water quality was partly in conformity with the fishery water standard and could be recycled. The control pond water continued to increase due to the removal of BOD5, COD and TN, the turbidity was significantly higher than that of the experimental pond, and the bloom appeared. This water cycle breeding model with simple structure and easy to promote and so on.
