  • 摘要: 基于农村生活污水间歇排放和太阳能能量密度昼夜变化特征,模拟光伏间歇曝气两级SBR处理农村污水,将聚磷菌(PAOs)和硝化菌分开控制在2个反应器中生长,分别命名为厌氧(缺氧)/好氧SBR(A/OSBR)和硝化SBR(N-SBR)。考察进水时间和回流对系统脱氮除磷效果的影响以及单个运行周期内污染物、溶解氧(DO)、氧化还原电位(ORP)和pH变化规律。结果表明,当进水时间为60 min和5 min,系统对TP的去除率分别为20.6%和56.5%;N-SBR出水与生活污水按1:2比例进入A/OSBR中,系统对TN、TP的去除率分别为57%和30.6%;N-SBR具有稳定的硝化效果,NH4+-N的去除率均能达到90%以上。DO和pH曲线的突跃点与反应终点保持一致,可将其作为实时控制参数。
    Abstract: Based on the intermittent characteristics of rural sewage discharge and solar energy density, a simulating photovoltaic intermittent aeration two-stage sequence batch reactor(SBR) system was proposed in rural sewage treatment. In this study, phosphate-accumulating organisms(PAOs) and nitrifying bacteria were controlled separately in two reactors, which were defined as anaerobic(anoxic)/oxic SBR(A/OSBR) and nitrification SBR(N-SBR), respectively. The effects of influent time and recirculation on nitrogen and phosphorus removal and the profiles of pollutants, dissolved oxygen(DO), oxidation reduction potential(ORP) and pH in one operating cycle were investigated. The results show that the removal efficiencies for TP are 20.6% and 56.5% at influent time of 60 min and 5 min, respectively. With N-SBR effluent recirculation at a ratio of 1:2, the removal efficiencies for TN and TP are 57%, 30.6%, respectively. Stable nitrification is obtained in N-SBR, in which the removal efficiency for NH4+-N could be above 90%. The elbows on DO and pH profiles match well with reaction ends, so they can be used as real-time control parameters.
