湘江株洲段氨氮污染变化趋势及规律研究

摘要

The comprehensive analysis was made to the pollution of ammonia - nitrogen in Zhuzhou section of different time and space in the latest 10 years. The results show that the pollution of ammonia - nitrogen is obvious, and the contents of Xia Wan section is the highest. The pollution trends of ammonia - nitrogen is lightening through the pollution control. Survey results showed that the industrial pollution is heavier than livestock and non - point source pollution. But untreated sewage has become the most important pollution.%对湘江干流株洲段中氨氮在近10年来时间、空间上的变化规律进行了全面分析.结果表明,氨氮污染的空间浓度变化较明显,霞湾断面的氨氮含量最高；通过对污染源的治理,目前氨氮污染有减轻趋势；同时对污染源情况进行详细调查,工业污染源相对畜牧业、非点源的污染较重,但未经处理的生活污水,则成为湘江株洲段最重要的氨氮污染源.
