| 摘 要： | 根据污水生物脱氮除磷原理设计了一套一体化反应器,并在其中分别投加普通生物悬浮载体和双室悬浮载体,以研究两者对生活污水同步脱氮除磷的效果。结果表明,在相同HRT下、温度控制在20～30℃和pH为6.5～7.8时,双室悬浮载体对污水总氮的平均去除率比普通生物悬浮载体的高近10%;但是两者对总磷及COD的去除效果相近,且对COD的去除效果较好,平均去除率在90%以上;Grau模型计算表明,HRT为12 h时,反应器中投加双室悬浮载体后的污水底物降解常数最大(2.18)。因此,把双室悬浮载体及其一体化反应器用于污水的同步脱氮除磷是一种高效的生活污水处理方法。 |
| 关 键 词： | 双室悬浮载体 脱氮除磷 水力停留时间 |

| Abstract: | The biofilm reactor which contained the integrated reactor and sedimentation basin was designed according to the principle of biodenitrification and dephosphorization from wastewater.The synchronous nitrogen and phosphorus removal effect from sewage was studied after the ordinary suspended bio-carrier and new double-room suspension bio-carrier was added to the reactor,respectively.At the same hydraulic retention time(HRT),the temperature of reactor was 20～30 ℃,the range of pH value was 6.5～7.8,the average removal rate of TN of the new carrier was nearly 10% higher than that of the common one.However,their removal efficiencies of total phosphorus and COD were similar,but the average COD removal efficiency reached more than 90%.So,the double room suspended carrier was effective for biodenitrification and dephosphorization of wastewater. |
