常州市地表水中氨氮输移分析及对策建议

目前常州市地表水中氨氮污染已成为最突出的问题。通过近2年来的监测和调查,参考有关资料和科研成果,估算出常州市地表水中年接纳氨氮总量为17998.0t/a,其中农田径流占32%,上游行政交界来水占30%,而城镇生活污水、农村生活污水、工业废水、城镇地表径流和规模化畜禽养殖等所占比重均不足13%。并据此提出了减轻地表水中氨氮污染的对策建议。

The Analysis and Countermeasures of Ammonia Nitrogen Transportation in Surface Water of Changzhou

Currently ammonia nitrogen pollution in surface water has become the most predominant problem in Changzhou. It was estimated that surface water accepted 17 998.0 t/a ammonia nitrogen in Changzhou by two years of monitoring and investigation and relevant information and scientific research. By calculation,farmland runoff contributed 32% of ammonia nitrogen,while the upstream runoff contributed 30% and the urban domestic sewage,rural domestic sewage,industrial wastewater,urban runoff and large-scale livestock breeding accounted for less than 13%. Finally,countermeasures were proposed on how to reduce ammonia nitrogen in the surface water.
