摘要： 为探究养殖尾水处理系统对淡水池塘养殖尾水的处理能力，在重庆地区选取一处建有尾水处理系统的养殖基地，使用现行有效的水质检测标准对其养殖尾水和各级处理单元出水进行水质测定分析，根据SC/T 9101—2007《淡水池塘养殖水排放要求》中的水质指标进行评价。结果显示，该尾水处理系统全年平均悬浮物含量（TSS）、五日生化需氧量（BOD5）、高锰酸盐指数（CODMn）、总氮（TN）、总磷（TP）去除效率分别为67.30%、77.13%、39.31%、48.39%、52.62%，去除效果较为明显；经系统处理的养殖尾水水质指标均优于一级标准，尾水可直接排放或循环利用。研究表明，该尾水处理系统对养殖尾水的处理具有明显效果，可以对养殖尾水中各项污染指标进行有效控制，对于改善水产养殖环境和降低水产养殖污染具有积极意义。

Abstract: In order to explore the treatment capacity of an integrated wastewater treatment system for freshwater pond aquaculture wastewater, this study selected an aquaculture base with an integrated wastewater treatment system in Chongqing. According to the water quality evaluation indexes in "Requirement for Water Discharge from Freshwater Pond Aquaculture " (SC/T 9101-2007), the water quality of aquaculture wastewater and effluent from various treatment units was measured and analyzed. The results showed that the annual average suspended matter content (TSS), 5-day biochemical oxygen demand (BOD5), permanganate index (CODMn), total nitrogen (TN), and total phosphorus (TP) removal efficiencies were 67.30%, 77.13%, 39.31%, 48.39% and 52.62% in the comprehensive wastewater treatment system, and the removal effect was obvious. After the wastewater treatment system is used to treat the aquaculture wastewater, the treated aquaculture wastewater is all lower than the level 1 standard of "Requirement for Water Discharge from Freshwater Pond Aquaculture ", and the wastewater can be directly discharged or recycled. The research shows that the integrated wastewater treatment system has an obvious effect on the treatment of aquaculture wastewater, and can effectively control the pollution index of aquaculture wastewater, which has a positive significance for improving the aquaculture environment and reducing aquaculture pollution.
