摘　　要：2008年7月-9月,将3个精养池塘分隔为鱼类养殖区和水质净化区,除了对照池外,在另外两个试验池净化区构建了由水蕹菜、滤食性贝类和生物刷组成的集成生物净化系统来净化精养池塘的水质,并在8月初引进高分子纳米增氧管来改善池塘溶氧水平。2个阶段的试验结果表明,该集成生物净化系统在净化池塘养殖水中氮、磷营养盐和有机污染物方面具有明显的功能优势互补,对水中TSS、TN、TAN、NO2--N、NO3--N、PO43--P和TP都有较好地去除效果。而高分子纳米增氧管使得池塘溶氧始终保持在5 mg.L-1以上。3个池塘两阶段的内梅罗水质综合营养指数表明,2号池第二阶段生物净化材料密度配置稍高。From July to September in 2008,each of the 3 intensive culture ponds was divided into two sections： fish culture section and water purification section.Except for the control pond,an integrated system consisted of water spinach,clam and biofilter brush were formed in the purification section of the other two ponds to improve water quality in the intensive culture ponds.Polymer namometer oxygen aerator was introduced in early August to increase the dissolved oxygen.The experiment results during these two stages indicate that the integrated system of biological methods has great mutual beneficial effects in removing the nitrogen,phosphorus and organic material in pond.It is effective in removing total suspended solids（TSS）,total nitrogen（TN）,ammonium nitrogen（TAN）,nitrite nitrogen（NO-2-N）,nitrate nitrogen（NO-3-N）,orthophosphate phosphorus（PO3-4-P） and total phosphorus（TP）.The dissolved oxygen content could reaches over 5 mg·L-1 with the help of polymer namometer oxygen aerator.The Nemero Index of water quality in the three ponds indicates that the desity of biological materials in pond No.2 during the second stage is a little higher.
