摘要
本文介绍了用两个 SBR组成的两段 SBR法与普通 SBR法处理宾馆污水的试验研究 ,结果表明 :这两种方法的 CODCr去除率相当 ,处理生活污水的活性污泥法经长期驯化都能达到比较理想的去除效果 ;两段法的出水水质稍好并且波动更小一些 ,添加第一段有助于保证出水水质的稳定 ;两段法的周期更短 ,能耗更低。从两段式 SBR法处理宾馆污水的试验结果可见 ,两段反应器中具有不完全相同的微生物种群 ,有利于降解污水中不同性质的有机物 ,提高了两段
Batch experiments were performed using two-stage Sequencing Batch Reactor(SBR), which consists of two SBR_s, and conventional SBR for treatment of hotel wastewater. The results showed that the COD_ Cr removal rates of both processes were equally matched. The disposal of domestic wastewater could achieve ideal effect through long-term domestication. The fluctuation of outlet using two-stage SBR was less than that using conventional SBR. The first stage was beneficial to the stabilization of outlet. The two-stage SBR process had shorter reaction time and lower energy consumption. It was indicated from the experimental results using two-stage SBR that both the two stages had not absolutely uniform mass of microbe, which was good to treat various organism in wastewater, this improved the efficiency and performance of the process.
