| Abstract: | The treatment of cooling wastewater of diesel locomotive by using biofilm reactor with rice husk as a carrier is introduced. The results showed that the method has a high removal efficiency of nitrate and nitrite nitrogen, COD. The average removal rate of NO\+-\-3\|N\,NO\+-\-2\|N, and COD was 94\^1%,92\^1%,66\^2%, respectively. The effluent quality is stabled and conforms to the national permitted criterion. The characteristics of the reactor is studied. |
