| 摘 要： | 利用粉煤灰对城市污水进行吸附处理,观察了吸附时间和灰水比对污水的处理效果.结果表明:粉煤灰处理污水的吸附平衡时间为2 h,粉煤灰吸附处理对污水中的COD、氨氮和总磷都有一定的去除效果,但是去除效果不同.当灰水比为1∶40时,对COD的去除率达到79.4%;当灰水比为1∶20时,氨氮去除率只有37.6%;当灰水比达到1∶10时,总磷的去除率可达到73.5%.

| Abstract: | The adsorption time and gray-water ratio of city sewage treatment with fly ash were observed.The results show that COD,ammonia nitrogen and total phosphorus in sewage could be eliminate by fly ash adsorption treatment,but the removal effects were different and adsorption equilibrium time was 2 hours.COD removal rate reached 79.4% at the 1∶40 of gray-water ratio,ammonia removal rate was only 37.6% at the 1∶20 of gray-water ratio and total phosphorus removal rate could be 73.5% at the 1:10 of gray-water ratio. |
