摘  要:
[目的]探寻好氧颗粒污泥处理高氨氮养殖废水过程中的影响因素,为工程实践提供理论依据。[方法]采用好氧颗粒污泥处理高氨氮猪场废水,研究化学需氧量(COD)、溶解氧(DO)和氨氮的去除率变化。[结果]在进水COD为1 000 mg/L,氨氮质量浓度为50mg/L的条件下,COD与氨氮的去除率均随处理时间增加而上升,但COD的去除效率远高于氨氮,处理4 h后,氨氮去除效率为55%,而COD去除效率接近90%。平稳运行下亚硝酸盐与硝酸盐浓度随时间的变化,始终稳定在较低的水平。[结论]采用好氧颗粒污泥处理高氨氮养殖废水具有良好的COD和氨氮去除效果,该技术值得推广。

摘  要:
[Objective] To explore the aquaculture-related factors treating high ammonia wastewater by aerobic granular sludge and provide a theoretical basis for engineering practice.[Method] The treatment of high ammonia wastewater using aerobic granular sludge was performed.The chemical oxygen demand(COD),dissolved oxygen(DO) and ammonia nitrogen removal efficiency were also detected.[Result] After treatment for 4 h at the condition of 1 000 mg/L COD and 50 mg/L NH4+-N,the removal efficiency of COD and NH4+-N were 90% and 55%,respectively.The nitrite and nitrate concentration stabilized at a lower level with time.[Conclusion] The treatment of high ammonia wastewater using aerobic granular sludge has a good removal efficiency of COD and ammonia nitrogen,and it is worth promoting.
