气提式接触氧化法处理生活污水的研究

Study on Domestic Wastewater Treatment by Airlift Contact Oxidation Process

将气提技术与接触氧化法相结合而形成气提式接触氧化工艺。采用该工艺处理生活污水,通过试验确定了其适宜的工艺参数,并分析了工艺运行稳定性、抗冲击负荷能力以及处理成本。结果表明,气提式接触氧化工艺结构紧凑、占地面积少、处理成本低,对COD和NH3-N的平均去除率分别达到了80.1%和58%,出水水质稳定而优良,可用作城市杂用水。同时,污水在池内循环接触填料,可降低填料层的高度。

The airlift contact oxidation process is the combination of airlift technology with contact oxidation method. The process was used to ters cost layo mov The were determin of the process ut, ed. ed through expefi were also analyzed treat domestic wastewater, the appropriate operating parameand the operation stability, anti-impact loads and treatment The results show that this process has some advantages of compact small occupancy area and low treatmen The effluent quality is stable and excell ght of the media can be reduced due to t cost. 80.1% of COD and 58% of NH3 - N can be reent, and it can be used as municipal miscellaneous water. its internal recycling system.
