摘要
应用MSBR硝化反硝化和UASB厌氧氨氧化串联工艺进行养殖废水处理研究。通过控制pH值8.0,溶解氧1.5 mg/L、游离氨10~20 mg/L,实现了曝气池亚硝氮积累率在60%以上;同时,UASB出水100%回流比至MSBR反应池,实现废水有机质、氮、磷循环有效去除。MSBR对系统COD,TN,TP去除贡献率分别为93%,75%~85%,70%~85%,UASB对系统COD,TN,TP去除贡献率分别为3%~7%,15%~30%,10%~20%。
A series process of MSBR nitrification and denitrification and UASB anammox was used to treat livestock wastewater.By controlling pH of 8.0,dissolved oxygen of 1.5 mg/L,free ammonia of 10~20mg/L,the accumulation rate of NO2--N in aeration tank was above 60%;at the same time,100%reflux effluent from UASB to MSBR reaction tank,as a result,the COD,TN and TP were removed from waste water.The contribution ratio of MSBR for COD,TN and TP reached 93%,75%~85%and 70%~85%,and the contribution ratio of UASB for COD,TN and TP reached 3%~7%,15%~30%and 10%~20%.
