SBR用于高浓度有机污水的处理——单级与两级处理系统的比较研究

Treatment of cattle wastewater with single and two-stage sequencing batch reactor systems

对单级和两级序批式反应器 (SBR)用于牛场高浓度有机污水的处理进行了试验研究 ,对其污水处理性能进行了比较。结果表明 ,与单级SBR相比 ,两级SBR处理系统可使用较短的水力停留时间而获得较高的污染物去除率和较好的出水水质 ,并可通过硝化过程实现氨氮的完全硝化。

The single stage and two stage SBR systems were investigated for treating high concentrated cattle farm wastewater and the performances were compared in terms of the removal efficiencies of carbon, solids and nitrogen. It was found that the two stage system consisting of SBRI and SBRII was more effective as compared with single stage SBR system and therefore recommended.
