摘  要:
采用规模为240 m3.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70 mg.L-1,SS的去除率在70%~95%之间,停留时间为2 h的产气率在1.26 m3.m-3d-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。

摘  要:
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·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.
