SBR法处理广东地区城市污水的最优工况
The best operational process of municipal wastewater treatment in Guangdong with sequencing batch reactor (SBR)
【摘要】 针对广东地区城市污水有机物浓度偏低,碳、氮、磷比例不合理的特点,通过用SBR法处理广东地区城市污水的试验,研究确定了在去除有机物的同时,脱氮除磷所需的最优工况:厌氧反应1h,曝气反应2~3h,沉淀时间为0 8~1h,污泥龄为17~21d.
【Abstract】 The experiment of municipal wastewater treatment with SBR in Guangdong has the following characters: the light consistence of organic matter, the unreasonable ratios of C、N、P. The best operational process of nitrogen and phosphorus removal while removing the organic matters effectively was: anaerobic 1 hour, aerobic 2~3 hours, sediment 0.8~1.0 hour, sludge age 17~21 days.
