摘要
螺旋升流式反应器(Spiral Up-Flow Reactor,SUFR)是一种新型的污水处理工艺,该工艺对污水中COD、TN、TP的去除效果较好,出水浓度分别低于28 mg/L、10 mg/L和0.5mg/L.本文对螺旋升流式反应器脱氮除磷系统中的反硝化吸磷现象进行了深入的研究,通过分析发现,适当的COD浓度和DO浓度有利于同时反硝化吸磷现象的发生。
Spiral up - flow reactor system is a new process on treatment of wastewater that has a good removal on COD, TN and TP. Results of the operation of the system showed that the effluent concentration of COD, total nitrogen（TN）, and total phosphorus（TP）was below 28mg/L, 10mg/L and 0.5mg/L respectively. In this paper tests of the simultaneous denitrifying phosphorus- uptake in the spiral upflow reactor system for biological nitrogen and phosphorus removal was conducted and analyzed. The resuks indicated that the appropriate concentration control of COD and DO could benefit to denitrify and uptake phosphorus with different environmental conditions.
