摘要
投加悬浮填料强化传统活性污泥法的脱氮能力,考察了低温、填料投配比和生物膜量等因素对脱氮效果的影响。中试结果表明,投加悬浮填料和采用前置反硝化的运行方式可使系统的氨氮和总氮去除率得到显著提高。
Suspended carrier was added to enhance the denitrification effect of conventional activated sludge process. Investigation was made for the factors such as low temperature, dosing ratio, and biofilm mass, which affected the denitrification effect. The pilot-scale test result showed that addition of suspended packing and use of pre-denitrification will significantly improve the removal rate of ammonia nitrogen and total nitrogen.
