摘要
设计开发了1种同心圆式新型水解酸化反应器,使用搅拌和上清液回流强化泥水混合效果,有效提高了废水的可生化性。中试研究表明:针对两类不同水质的难降解废水,其对COD的去除率超过46%和36%,并通过改变运行方式有针对性地降低运行成本。通过与其他各类水解酸化反应器的对比实验,新型水解酸化反应器可以提高6个百分点左右的COD去除效果。
A novel hydrol which could improve ysis-acidification reactor in concentric structure was designed and developed, biodegradability of wastewater effeetively by the enhancement of the mixture performance due to the stirring and reflux. The pilot-scale study showed that the COD removal rate could reach over 46% and 36% respectively treating the two different kinds of refractory wastewater. Moreover, the reactor could cut down the operational cost through the variation of the operation mode. According to the comparison with other hydrolysis-acidification reactors, the result showed that a 6 percentage point of improvement in COD removal could be reached to the novel hydrolysis-acidification reactor.
