【摘要】 本文旨在将微氧水处理技术和SBR工艺相结合处理模拟生活污水,探索微氧SBR反应器处理生活污水的可行性,探索生活污水低耗高效处理的新技术。采用有效容积为3L的微氧SBR反应器对模拟生活污水的处理进行了实验室小试,考察了温度、水力停留时间、进水水质、进水时间、搅拌频率等各种因素对处理效果的影响,初步考察了微氧SBR对生活污水中TN、TP的去除效果,推荐出各参数的最佳取值。并对其与好氧SBR、厌氧SBR工艺进行了对比及经济性能分析。研究结果表明:（1）将微氧SBR单独用于模拟生活污水的处理是可行的,推荐参数为:水力停留时间12h;进水COD浓度400mg/L,对应的进水SS和NH₃-N分别为356mg/L及40mg/L;进水时间1.5min;搅拌频率1min/45min;温度20℃。此时,出水COD、NH₃-N均满足《污水综合排放标准》（GB8978—1996）中规定的一级排放标准要求,出水SS满足二级及以上排放标准;（2）微氧SBR工艺对生活污水中的TN有一定的去除效果,HRT=12h时,进水TN40mg/L,出水15mg/L左右,去除率可达60%;（3）微氧SBR工艺对生活污水中的TP有一定的去除效果,HRT=12h时,进水TP浓度9mg/L左右,出水3.6～4.4mg/L（平均4.0mg/L）,去除率在55%左右;（4）每处理1000gCOD,微氧SBR工艺处理生活污水需氧量仅为好氧SBR的26.7%左右,可以节省大量曝气能耗,且污泥产量少,比好氧SBR具有更高的经济价值。更多还原

【Abstract】 Experimental works in this paper were focused on the treatment of simulate domestic wastewater by sequencing batch reactor process cooperating with micro-aerobic techniques, and objectives were: to exploit the feasibility of disposing domestic wastewater only by micro-aerobic SBR, and to look for high-efficient, economic ways to dispose domestic wastewater. Simulated domestic wastewater was disposed by micro-aerobic SBR with 3L efficient cubage. It is have been researched that the affections of factors on wastewater disposal effect, such as temperature, hydrolic retention time, COD concentration of influent, influent time, whisk frequency, to choose the best react condition. At the same time, the removal rate of TN, TP by micro-aerobic SBR were primarily reviewed. Compared it with aerobic SBR and ASBR and made a primary economic capability analysis. The experimental results showed that:（1） It is feasible of disposing domestic wastewater only by micro-aerobic SBR under fit conditions. Recommended conditions are: hydrolic retention time 12h, influent COD 400mg/L, influent time 1.5min, whisk frequency 1min/45min, and temperature 20℃.（2）Micro-aerobic SBR can reach a certain disposal rate of TN in domestic wastewater. Disposal rate can reach 60% when HRT is 12h and influent TN is 40mg/L.（3） Micro-aerobic SBR can reach a certain disposal rate of TP in domestic wastewater. Disposal rate can reach 55% when HRT is 12h and influent TP is 9mg/L.（4） Micro-aerobic SBR just costs 26.7% O₂ of aerobic SBR disposing each 1000gCOD and has less sludge output. So it can save a great deal of energy and has a better economic value.更多还原
