摘　　要：传统SBR以滗水器作为设计出水的主要装置,为了改变滗水器设备对于SBR工艺应用的限制,提出了无滗水器SBR工艺。将SBR工艺池型作出修改,采用固定堰出水方式省去了滗水器,并将固定堰式SBR与传统SBR出水方式的实际处理效果进行了对比,结果表明:新型固定堰式SBR污水处理工艺对于COD,BOD5以及SS的去除率均优于传统滗水器SBR污水处理工艺;在冬季运行气温较低的前提下,固定堰式SBR污水处理工艺对于COD,BOD5,SS的去除率仍然能够稳定达标。因此,可以认为固定堰式SBR可以作为替代传统滗水器式SBR的新型SBR工艺。The decanter is one of the core unit in the traditional SBR process, in order to dissolve the decanter limit problem impose to the traditional SBR, the new process SBR without decanter is proposed in this article. This new type of SBR modified the original tank structure, utilizing fixed weir as the effluent pattern. We made a comparative analysis for effluent water quality between fixed weir SBR and original SBR. As a result, making the water level stable inside of water tank is a good method to raise the water quality of effluent. In conclusion, we believe that the fixed weir SBR can become one replaced type of SBR in the future.
