摘要:
通过设置不同增氧条件，研究立体弹性填料强化生态浮床对淡水养殖水体的净化效果及出水中氮的组成。结果表明，当增氧强度为1 L/min、每天增氧3 h时，立体弹性填料强化生态浮床对淡水养殖水体中TN、COD和TP的去除率最高，分别为73.9%、81.7%和54.9%；不增氧会导致系统出水中NH4+-N浓度较高，当每天增氧4 h或8 h时会造成出水中NO3--N积累。因此，综合考虑对上海市淡水养殖池塘水体的净化效果及出水中“三氮”的组成，当增氧强度为1 L/min、每天增氧3 h时，立体弹性填料强化生态浮床系统运行效果最佳。
Abstract:
Purification efficiencies of enhanced floating treatment wetlands (EFTWs) on aquaculture water and the nitrogen composition of the effluent under different aeration conditions were studied. When aeration intensity and time were 1 L/min and 3 hours per day, the removal efficiencies of TN, COD and TP in aquaculture water were the highest, which were 73.9%, 81.7% and 54.9%, respectively. The absence of aeration resulted in a higher concentration of?NH4+-N in the effluent of the system, and?NO3--N would accumulate when the aeration time was 4 or 8 hours per day. Therefore, purification efficiency and composition of nitrogen in the effluent were comprehensively considered, and purification efficiency of EFTWs with three-dimensional elastic packing was the best when aerobic intensity and time were 1 L/min and 3 hours per day.
