摘　　要：为评估设施甲鱼养殖中隔污装置对水质的改善效果。使用72只质量约为300 g的甲鱼,在实验室条件下以配备与未配备隔污装置的小型甲鱼养殖池作为试验组和对照组,测定了氨氮、浊度、化学需氧量(COD)、亚硝酸盐氮等水质指标的变化情况,并采用统计分析方法对数据进行处理。结果显示,试验组的氨氮质量浓度显著高于对照组,最高可达108 mg/L。对照组与试验组的浊度和COD平均变化率分别为14.2%、8.4%和39.5%、15.5%。养殖周期内,对照组COD、总磷和总氮的排放量分别为286.59 g、68.33 g和12.32 g;试验组则为92.21 g、46.01 g和5.07 g。研究表明,尽管试验组的氨氮质量浓度高于对照组,但隔污装置显著降低了浊度和亚硝酸盐氮质量浓度的平均变化率,并减少了养殖周期内COD、总磷和总氮的排放量。此外,换水周期延长至15 d,有效减少了换水量及污染物排放。这一结果表明,隔污装置能够有效地隔离污染物,在提升养殖水质方面具有显著效果。The present study was conducted to evaluate the efficacy of a pollution isolation device in improving water quality in facility-based soft-shelled turtle(Pelodiscus sinensis)aquaculture.A total of 72 soft-shelled turtles,each weighing approximately 300 g,were utilized in this experiment.Two groups were established:one with a small turtle culture pond equipped with a pollution isolation device(treatment group)and another without the device(control group).Water quality parameters,including ammonia nitrogen,turbidity,chemical oxygen demand(COD),and nitrite nitrogen,were monitored and statistically analyzed.The results indicated that the ammonia nitrogen concentration in the treatment group was significantly higher than that in the control group,reaching a maximum of 108 mg/L.The average change rates for turbidity and COD in the control and treatment groups were 14.2%and 8.4%,and 39.5%and 15.5%,respectively.Over the culture period,the control group discharged 286.59 g of COD,68.33 g of total phosphorus,and 12.32 g of total nitrogen,whereas the treatment group discharged 92.21 g of COD,46.01 g of total phosphorus,and 5.07 g of total nitrogen.The study demonstrated that,despite the higher ammonia nitrogen concentration in the treatment group,the pollution isolation device significantly reduced the average change rates of turbidity and nitrite nitrogen and decreased the discharge of COD,total phosphorus,and total nitrogen during the culture cycle.Moreover,extending the water exchange period to 15 days effectively reduced the volume of water exchanged and the emission of pollutants.These findings suggest that the pollution isolation device is effective in isolating pollutants and significantly improves water quality in soft-shelled turtle aquaculture systems.
