摘要 分段进水A/O生物脱氮工艺中,为充分利用污水中的碳源及系统各段的硝化容量。且有效地应对进水扰动,需进行合理的进水流量分配和缺氧/好氧体积分配。针对分段进水A/O工艺的结构和运行特点,对分段进水工艺系统的流量分配方法和体积分配方法进行理论分析,并对实际运行优化方法进行讨论.对于系统的流量分配,提出以进水ρ(C)/ρ(N)作为控制参数,并分别对碳源充足、碳源恰好合适和碳源不足3种情况进行讨论,同时给出每种情况下的运行优化方法;对于体积分配,分析缺氧/好氧体积比对系统硝化容量及其对进水中COD利用程度的影响,并对不同负荷下缺氧/好氧体积优化进行了分析. In step-feed A/O biological nitrogen removal system,the optimal influent flow rate distribution can make full use of the carbon source in influent,and the appropriate anoxic/oxic volume ratio can save the operation cost and resist the influent disturbance effectively.Based on the characteristics of configuration and operation of step-feed process,this paper analysed the influent flow rate and volume distribution theoretically and discussed the optimization of operation.Regarding to the influent flow rate di...
