摘　　要：采用规模为240m^3·d^-1的厌氧颗粒污泥膨胀床（EGSB）反应器对生活污水进行研究。试验结果表明：采用此系统处理生活污水，出水水质良好。COD的去除率在73％～90％之间，出水的COD值小于70mg·L^-1，SS的去除率在70％～95％之间，停留时间为2h的产气率在1、26m^3·d^-1，出水的氨氮、乙酸值比进水的高；硝酸根离子出水值比进水值低。Municipal wastewater treatment with pilot scale EGSB （240 m^3·d^-1） was conducted. The results indicated that the process was effective. The COD removal rate was in 72% - 90%. The COD content of effluent was less than 70 mg· L^- 1, SS removal rate was about 70% -95%. The best retention time was 2 hours with gas production rate of 1.26 m^3·d^-1 .The ammonia nitrogen and acetic acid contents in effluent were higher than those in influent. The total nitrogen,total phosphorus and nitrate ion in effluent were lower than those in influent.
