| 摘 要： | 采用悬浮载体生物流化床工艺处理城市生活污水,考察了进水pH对其处理效果的影响.结果表明,进水pH变化不影响有机物去除效果;氨氮(NH3-N)去除率随pH上升而上升,最佳pH为7.5;当pH在6.5~8.0之间变化时,总氮(TN)去除率基本保持在50%以上,但当pH值>8.2和<6.1时,TN去除效率有着下降的趋势.因此在指定试验条件下,pH变化不影响有机物的去除;pH为中性或偏碱性的环境下,反应器对NH3-N及TN有很好的去除效果. |

| Abstract: | Wastewater was treated by integrated suspension carried biological fluidized block.A pH effect on removal efficiency was studied.It was found that pH variation had no influence on CODCr removal.The removal efficiency for NH3-N increased with increasing pH,with optimum at pH 7.5.Total nitrogen removal was more than 50%,but efficiency went down at pH higher than 8.2 or lower than 6.1.So under the set conditions pH variation had no influence on CODCr and NH3-N removal,and total nitrogen removal is good with pH... |
| Keywords: | biological fluidized block pH value removal efficiency |
