| 摘 要： | 采用EGSB+SBR组合工艺对邯郸市生活污水进行了试验研究.结果表明,在常温下进水COD为245～420mg·L~(-1),EGSB反应器的水力停留时间为3h,反应器COD容积负荷达到3.5 kg·m~(-3)·d~(-1),上升流速达到6.5m·h~(-1)时,COD去除率为95%(COD<60mg·L~(-1)),但氨氮去除效果不佳,故采用SBR工艺为后续处理工艺,其出水的氮、磷等指标达到国家一级排放标准(GB8978-1996).

| Abstract: | Domestic wastewater of Handan city is treated by EGSB+SBR combined process. When the COD of influent is 245~420 mg·L~(-1), for EGSB reactor ,the hydraulic retention time is 3 h, the hydraulic load of COD is 3.5 kg·m~(-3)·d~(-1), the up-flow velocity is 6.5 m·h~(-1), the COD remove rate reaches 95%( COD<60 mg·L~(-1)).But the N, P removal rate is not good, SBR process is used to make N, P reach national first discharge standard (GB 8978-1996). |
