摘要
在池塘工业化养殖系统净水区分别挂养河蚌和栽种浮床植物,研究不同模式的水质净化效果。结果表明,在经济成本相似的情况下,河蚌挂养去除氮磷效果优于浮床植物,浮床植物增加水体溶解氧和降低COD效果好于河蚌挂养。
The water purification effects of different models were studied in the water purification area of the in-pond aquaculture system by hanging freshwater mussel and planting floating bed plants,respectively.The results showed that at the similar economic cost,the nitrogen and phosphorus removal effect was better than that of floating bed plants,while the effects of dissolved oxygen increasing and COD decreasing were better than that of floating bed plants.
