| 摘 要： | 将二级城市污水或受污染的天然水用作火电厂循环水的补水时，要考虑氨氮硝化过程带来的不良影响。试验和实践表明，补水中氨氮含量高时，循环水的pH值异常下降，铜管腐蚀速率明显上升，细菌总数大量增加，氧化性杀菌剂的杀菌效果被降低。对此进行分析后，给出了相关的治理措施。 |

| Abstract: | In case of using secondary urban sewage or polluted natural water as makeup water of the circulating water in thermal power plants, the bad influence of nitrification process concerning ammonium nitrogen should be considered. Test and practice show that the high content of ammonium nitrigen in makeup water makes the pH value of circulating water to be abnormally lowered, the corrosinon rate of copper tubes being raised, the total amount of bacterum beinggreatly inereased, and the sterilizing effect of oxidizing bactericide being decreased. In this connection, related remedial measures are given. |
| Keywords: | thermal power plant circulating water secondary urban sewage ammonium nitrogen nitrification process micro-orgamism corrosion |
