| 摘 要： | 选用生物陶粒为滤料,考察了水力负荷、回流比、温度对上向流曝气生物滤池(UBAF)反硝化性能的影响.结果表明:UBAF的脱氮效果随着水力负荷的增大而降低,当水力负荷小于2.0 m3/(m2·h)时,对NH3-N、TN均能达到较好的去除效果,去除率分别为88.26％和72.22％;回流比对NH3-N去除效果的影响较小,对T... |

| Abstract: | With biological ceramsite as the filter media,the effects of hydraulic loading,reflux ratio and temperature on the denitrification performance of up-flow biological aerated filter(UBAF) were investigated.The results showed that: the denitrification capability of the UBAF decreased with the increase of hydraulic loading,the removal rates of NH3-N and TN reached 88.26% and 72.22% respectively when the hydraulic loading was lower than 2.0 m3/(m2·h);the reflux ratio had little influence on NH3-N removal but great influence on TN removal,when the reflux ratio was controlled at the range of 150% to 200%,the average mass concentration of TN in the effluent water was lower than 13.8 mg/L;the remval rate of TN was greatly affected by temperature,when the water temperature was higher than 20 ℃,the average mass concentration of TN in the effluent water was 10.8 mg/L with the average removal rate of 78%. |
