【摘要】 为了构建新的鱼菜共生系统,并对其关键参数进行优化,本实验采用水质国标检测方法从对比分析不同种植床水流方式（潮汐式、溢流式）、不同种植床基质（珊瑚石、细沙）以及不同循环水体流速（0L/h、150L/h、300L/h、450L/h、600L/h）下,系统对水体氮磷元素(NH₄⁺-N,PO₄^3--P,NO₂^--N)的处理效果。结果显示:（1）种植床水流方式为潮汐式,相比溢流式,系统对水体中氨态氮、亚硝态氮处理效果更优,溢流式系统对水体中磷酸态磷处理效果更优,但两者相差不大;（2）种植床基质为珊瑚石,相比较细沙,系统对水体中氨态氮、亚硝态氮处理效果更优,细沙系统对水体中磷酸态磷处理效果更优;（3）系统循环水体流速为450L/h,系统对水体中氨态氮、亚硝态氮处理效果更优,流速为600L/h系统对水体中磷酸态磷处理效果更优。更多还原

【Abstract】 In order to construct a new aquaponics system and optimize its key parameters, experiment used methods of national water quality detection and comparative experiments to analysis treatment effects of nitrogen and phosphorus(NH₄⁺-N, PO₄^3--P, NO₂^--N) in water by system in different flowing patterns（tidal type, overflow type） of water, different stroma（coral stone, fine sand） of growing bed, different flowing rate（0 L/h, 150 L/h, 300 L/h, 450 L/h, 600 L/h） of circulating water. Results show:（1） compared with overflow type, tidal type has better effect on NH+-4-N and NO₂^-N in the water, but overflow type has better effect on PO₄^3--P in water, but the difference is not big;（2） compared with the fine sand, the coral stone has better effect on the treatment of NH₄⁺-N and NO₂^--N in the water, and the fine sand is better for the treatment of PO₄^3--P in the water;（3） the speed of water flowing is 450 L/h, the system has better treatment effect on NH₄⁺--N and NO₂^-N in the water. The flowing rate is 600 L/h, the system has better effect on the treatment of PO₄^3--P in water.更多还原
