生态浮床对鱼塘水质的净化评价及管理——以华宇园林苗木生态园鱼塘为例

Purification evaluation and management of fish pond water quality by ecological floating bed:Taking the fish pond of Huayu Garden Nursery stock ecological garden as an example

以华宇园林苗木生态园的鱼塘为研究对象,以种植生态浮床前后水体中的总氮(TN)、总磷(TP)、氨氮、化学需要量(COD)为评价指标,对水质进行评价。分别从时间和空间两个维度,分析和对比生态浮床对水体中氮、磷的吸收效果、对水体中COD的影响趋势。结果表明,生态浮床对整个水域的氮和磷以及COD都有一定的吸收作用,其中对总氮的去除率最高可达15.2%,总磷的去除率最高可达56.3%。提出生态浮床对鱼塘水质净化的治理管理理念。

Taking the fish pond of Huayu Garden Ecological Nursery as the research object,total nitrogen(TN),total phosphorus(TP),ammonia nitrogen and chemical demand(COD)in water before and after planting ecological floating bed as evaluation indexes,the water quality was tested.Respectively from two dimensions of time and space,the absorption effect of ecological floating bed on nitrogen and phosphorus in water and the influence trend of of COD in water were analyzed and compared.The results showed that the ecological floating bed for the whole water of nitrogen and phosphorus and COD has certain absorption effect,including removal rate up to 15.2%of total nitrogen,total phosphorus removal rate up to 56.3%.The management concept of ecological floating bed for fish pond water purification was put forward.
