| 摘 要： | 根据已建立的ＮＨ_３－Ｎ、ＮＯ_２~－－Ｎ、ＮＯ_３~－－Ｎ基本水质数据库，对京杭大运河（杭州段）三氮的水质现状和趋势作了分析，结果表明，工业废水与生活污水是河水中ＮＨ_３－Ｎ升高的主要原因，ＮＯ_２~－－Ｎ和ＮＯ_３~－－Ｎ与硝化反应有关，不同水期对三氮都有影响。

| Abstract: | Based on the erected NH_3~--N,NO_2~--N and NO_3~--N water quality data bank,the water phase and changing trend of three nitrogen compounds (NH_3-N,NO_2~--N and NO_3~--N)in the Grand River Hangzhou Section (from Sanbao Ship Lock to Tangxi Bridge)were analyzed.The results showed that industrial wastewater and life sewage were the major factors which enhanced NH_3~--N pollution.The concentration of NO_2~--N and NO_3~--N in the river was connected with nitrification and three nitrogen compounds in the river were impacted by different water season. |
