摘　　要：对序批式反应器 (SBR)的特点进行了简要的介绍。研究了水力停留时间和有机负荷率对单级和两级SBR用于牛场污水处理时污染物去除率和出水水质的影响 ,并对单级和两级SBR的污水处理性能进行了比较。研究结果表明 ,当用单级SBR处理 10 0 0 0mg LCODCr的污水时 ,1d水力停留时间即可获得较好的处理效果 ,但出水中仍含有一定量的氨。两级SBR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 。The characteristics of Sequencing Batch Reactor (SBR) was introduced.The wastewater from a cattle ranch was treated with the single stage and two stage SBR,respectively.It was found that the single stage SBR was capable of achieving satisfactory carbon,solids and nitrogen removal efficiency and good effluent quality.But two stage SBR proved to be more effective in terms of treatment efficiency and ammonia conversion as compared with single stage SBR system.
