曝气生物滤池最佳反冲洗周期及反冲洗方式研究

Research on the optimum backwashed cycle and the backwashed methods of the biological aerated filtrated reactor

研究曝气生物滤池的最佳反冲洗周期和局部反冲洗问题,揭示了曝气生物滤池反冲洗规律．曝气生物滤池最佳反冲洗周期研究表明：瞬时产水率v(t)和周期产水率V(t)相等的时间为最佳反冲洗周期；局部反冲洗方法可减少曝气生物滤池反冲洗用水量．最佳反冲洗周期及局部反冲洗的研究,对于实现曝气生物滤池的自动化操作,具有重要作用．

The optimum backwashed cycle and the part backwashed methods of the Biological Aerated Filtrated Reactor were studied in the paper and the rules of the Biological Aerated Filtrated Reactor were discovered. The optimum backwashed cycle research showed that when instantaneous water production rate （v（t） ） is equal to cycle water production rate （ V（t） ）, is the optimum backwashed cycle. The part backwashed methods decrease the water consumption and improve effluent quality. The optimum backwashed cycle and the part backwashed methods are quite important to achieve the automation operation control.
