Nutrient removal is essential for a

Nutrient removal is essential for aquaculture wastewater treatment to protect receiving water from eutrophication and for potential reuse of the treated water. The integration of aquaculture with agriculture appears to be an excellent way of saving water, disposing aquaculture wastewater and providing fertilizer to the agricultural crop. The study was conducted to evaluate aquaponics recirculation system (ARS) performance in removing inorganic nitrogen and phosphate from aquaculture wastewater using water spinach (Ipomoea aquatica) and mustard green (Brassica juncea). The results showed that water spinach was able to significantly reduce the total ammonia nitrogen, nitrite-N, nitrate-N and orthophosphate with efficiencies of 78.32–85.48%, 82.93–92.22%, 79.17–87.10%, and 75.36–84.94%, respectively, compared to mustard green that removed the nutrients in the range of 69.0–75.85% for total ammonia nitrogen, 72.49–79.34% for nitrite-N, 66.67–80.65% for nitrate-N, and 66.79–77.87% for orthophosphate. Overall results suggest that water spinach is better than mustard green in nutrient removal in the aquaponics system used due to its root structures provided more microbial attachment sites, sufficient wastewater residence time, trapping and settlement of suspended particles, surface area for pollutant adsorption, uptake, and assimilation in plant tissues.

水产养殖废水处理，以保护受纳水体的富营养化和潜在的重用的污水脱氮除磷至关重要。水产养殖与农业一体化似乎是极好的节约用水、 水产养殖废水处理提供给农作物施肥方法。这项研究进行评估中无机氮去除的水培技术回流系统 (ARS) 性能和磷酸盐去除水产养殖废水水菠菜 (蕹菜) 和芥末绿 (芥菜)。结果表明，水菠菜可以显著地降低总氨氮、 亚硝酸盐氮、 硝酸盐氮和正磷酸盐 78.32 – 85.48%、 82.93 — — 92.22%、 79.17 — — 87.10%和 75.36 — — 84.94%效率分别，相比芥末绿 69.0 — — 75.85%总氨氮、 72.49 — — 79.34%亚硝酸盐-n，66.67 — — 80.65%硝酸-n 和 66.79 — — 77.87%为正磷酸盐的范围中删除的养分。总体结果表明水菠菜是比芥末绿在脱氮除磷中由于其根结构使用的水培技术系统提供更多微生物附着站点、 足够废水停留时间、 陷印和沉降的悬浮的颗粒，表面面积为污染物吸附、 吸收和植物组织中的同化。
