Aiming at the high pollution load of aquaculture wastewater and the low level of profits,oxidation pond treatment process was proposed. The fertilizer for the experiment was quail dung, and the aquatic creature was eichhomia crassipes. The objective was to study the effect of oxidation pond on aquaculture wastewater treatment and compare the effect on aquaculture wastewater treatment between oxidation pond and natural wetland. After treatment for one week, the results showed that the average removal rates of COD.TN and TP were 61.35% ,59.16% and 64.94% respectively by oxidation pond, but the removal rates of COD, TN and TP were 38.46% ,62.43% and 66.09% separately by natural wetland. From the comparison between the two treatment, oxidation pond had better removal rate of COD, but the two treatments had similar removal rates of TN and TN.%针对水产养殖废水污染负荷高,而其养殖行业的利润低的特点,提出氧化塘的处理工艺.以鹌鹑粪作为肥料,以水葫芦为主要的水生生物,研究氧化塘对水产养殖废水的处理效果,比较水生植物为水葫芦的氧化塘和自然湿地对水产养殖废水中各污染物指标的处理效果.实验结果表明,经过1周的时间,氧化塘对废水中的COD、TN、TP的平均去除率可达到61.35％、59.16％、64.94％,而自然湿地对废水中的COD、TN、TP的去除率为38.46％、62.43％、66.09％；2种处理结果相比,水生植物为水葫芦的氧化塘对COD的去除效果更好,对TN、TP的净化效果相近.
