自动控制悬浮填料序批式反应器脱氮除磷的研究

Study on automatic control of sequencing batch reactor of suspended filler of nitrogen and phosphorus removal

选用球形多孔悬浮填料,利用序批式生物膜反应器对模拟城市污水进行试验研究,确定可以以氧化还原电位作为工艺主要控制参数。稳定运行时COD、TN、TP的平均去除效率分别达到97%、83%、94%,出水水质达到了《城镇污水处理厂污染物排放标准》(GB18918-2002)的一级A标准。

New ball pore of suspended filler was selected to study the treatment of simulated wastewater of city by sequencing batch reactor of suspended filler.confirmed redox potential can be used as the main control parameter of this process.The removal efficiency of COD,TN and TP were 97%,83% and 94% respectively,with effluent quality satisfactory to Class I.
