SBR改良工艺处理北京市城乡结合部污水的研究

Treatment of Sewage from Beijing Urban-rural Conjunction Areas by Improved SBR Process

通过采用SBR改良工艺处理城乡结合部生活污水的试验,根据城乡结合部污水的特点,采用SBR改良工艺,研究工艺的处理效果、水量波动和排水位置对处理效果的影响。结果表明,SBR改良工艺对城乡结合部污水有良好的处理效果;SBR改良工艺耐冲击负荷能力大,在连续2倍进水量的情况下,仍有良好的处理效果;降低排水位置对出水SS有一定的影响,但SBR工艺的污泥沉降效果好。

Through treatment of sewage from Beijing urbanrural conjunction areas by improved SBR process, this paper studied the treatment effect, water quantity fluctuation and discharge position of the process. The results show that the improved SBR process achieves good treatment effect on the sewage from urban and rural areas. The improved SBR process has a good load capacity of impact resistance, even under the situation of two times of inflow water. Reducing the water discharge level has a certain effect on SS, but the sludge sedimentation effects are still preferable.
