摘　　要：通过构建池塘养殖水异位生态治理技术工艺,比较处理工艺不同环节水质指标,分析了治理工艺对池塘养殖水的水质净化效果及其应用价值。结果表明,与原养殖池相比,生态处理工艺中的沉淀池、曝气氧化池以及生态净化池的化学需氧量、氨氮、硝酸盐氮、亚硝酸盐氮、余氯、总氮、总磷等质量浓度均呈显著下降趋势,溶解氧呈上升趋势,池塘养殖水生态处理工艺水质净化效果明显。经生态处理工艺处理后的池塘养殖水符合《淡水池塘养殖水排放要求》(SC/T 9101—2007)二级标准,且余氯、总磷浓度达到一级标准,实现养殖用水的达标排放和循环利用。By constructing ectopic ecological treatment technology for pond aquaculture water, the water quality indexes of different links of treatment technology were compared, and the purification effect and application value of treatment technology for pond aquaculture water were analyzed. The results showed thatcompared with the original aquaculture ponds, in the process of ecological treatment of sedimentation tank, aeration oxidation pond and ecological purification pool of the chemical oxygen demand(cod), ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, residual chlorine, total phosphorus and total nitrogen concentration was negatively significant decline, dissolved oxygen showed an increasing trend, ecological pond aquaculture water treatment process has obvious purification effect. The pond aquaculture water treated by the ecological treatment technology conforms to the grade ii standard of freshwater pond aquaculture water discharge requirements(SC/T 9101—2007), and the concentration of residual chlorine and total phosphorus reaches the grade I standard, achieving the standard discharge or recycling of aquaculture water.
