摘要
采用软性填料的生物接触氧化器和生物滤池组合工艺处理生活污水,研究水力负荷、气水比和有机负荷对处理效果的影响。结果表明:生物膜和生物滤池联用的组合工艺可以大幅提高有机负荷并节能,系统COD,NH4+-N去除率分别稳定在87%,82%以上。
The domestic sewage was treated by combined processing of soft filling biological contact oxidation and bio-filter,the treatment effects were discussed at different hydraulic loading,ratio of air to water and organic loading.The results showed that the combined process posed both merits,improvement of organic loading and saving energy.The COD and NH4+-N removal rate of the system stabilized at above 87% and 82% separately.
