摘要
以稻壳作为微生物载体进行内燃机车冷却污水处理试验。结果表明 :在进水NO-2 N质量浓度为 1 2 9mg L ,NO-3 N质量浓度为 5 8 2mg L下 ,出水NO-2 N质量浓度为 6 1mg L ,NO-3 N质量浓度为 4 9mg L ,平均去除率分别为94 1 %和 92 1 %。COD的平均去除率为 66 2 %。在试验研究的基础上研究分析了稻壳生物膜反应器的特性 ,为其在相关污水处理中的应用提供了实验依据 。
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.
