SBBR工艺同步脱氮除磷处理效能研究

污水生物处理技术的处理效能是其能否得到广泛应用的主要指标之一,试验采用序批式生物膜反应器(SBBR),以人工模拟污水为处理对象,在温度、有机物浓度和营养物浓度较宽的变化范围内进行了连续运行,对SBBR工艺脱氮除磷的处理效能进行了系统研究.试验结果表明:SBBR工艺处理生活污水对水质的变化具有一定的抗冲击能力,对COD、氨氮、总氮、总磷和SS的平均去除率分别为87.95%、76.68%、47.87%、84.58%和89.22%,在低温运行条件下,对污水的处理也能保持一定的处理效能.SBBR工艺在小型点源污染控制和污水脱氮除磷深度处理中是一种行之有效的同步脱氮除磷工艺.

Study of the efficiency of simultaneously removing nitrogen and phosphoruswith sequencing batch biofilm reactor (SBBR)

Treatment efficiency for wastewater biological treatment technology is one of the main criteria for judging whether it has wide application or not.Taking synthetic domestic wastewater as the experimental water, the present paper used sequencing batch biofilm reactor(SBBR) to systematically investigate the efficiency of removing nitrogen and phosphorus on the basis of continuous operation under wide ranges of temperatures,concentrations of organic matters,and nutrient concentrations.The results show that the sequencing batch biofilm reactor(SBBR) has some buffer ability to water quality changes during the treatment process,that the average removal rates for COD,NH_3-N,TN,TP,and SS were 87.95%,76.68%,47.87%,84.58%,and 89.22%,respectively.Even at low temperature SBBR had stable treatment efficiency.It was concluded that SBBR was an effective technology for simultaneously removing nitrogen and phosphorus during control of small-scale point polluting sources and further treatment of water.
