包埋固定化间歇式生物工艺处理生活污水

Characters of Immobilization SBR Process in Domestic Wastewater Treatment

将包埋固定化技术应用到间歇式生物处理工艺中,形成包埋固定化SBR反应器(间歇式反应器),通过与普通活性污泥法SBR反应器处理生活污水效果的对比试验,研究了该工艺实际应用的优越性。试验结果表明,前者达到最大COD去除率的反应时间比后者缩短了2 h,抗进水COD冲击负荷能力提高约50%,稳定运行时对LAS的去除效果高出约30%,并有很强的抗LAS毒害的能力。

Embedded immobilization SBR is the reactor that combines embedded immobilization technology with SBR technique. Compared with activated sludge SBR, this technique is applied to the process on treating domerstic sewage, its advantage is presented. The results show the time that embedded immobilization SBR need to reach maximum COD removal efficiency can be reduced 2 hours, and the COD resistance ability can be increased 50%. Under stable operation, the LAS removal efficiency can be promoted 30%. Meantime the reactor has a strong LAS resistance ability. 2 tabs, 6 figs, 8 refs.
