苏州地区水体氮污染状况

报告了地处太湖流域中心地带的苏州地区水体氮污染研究结果。对苏州吴县境内主要河流、湖泊和农村浅层地下水氮污染现状进行了评估。根据不同水体 ,不同形态无机氮的浓度及PO3-4 的浓度 ,对河水 ,湖水和井水中氮的来源进行了初步讨论 ,比较了河湖水体氮污染的季节性变化 ,提出了减缓这一地区水体氮污染的对策。

SITUATION OF NITROGEN POLLUTION IN WATER BODIES IN SUZHOU REGION

In this paper presented are results of a study on N pollution in water bodies in Suzhou region, which is located in the center of the Taihu Valley. The present situation of N pollution in the major rivers and lakes as well as in the shallow groundwater in rural areas are evaluated. For different water bodies, concentrations of PO 3- 4 and different forms of inorganic N, N source in the rivers, lakes and well waters are investigated. Seasonal variation of N pollution in the rivers and lakes are compared and countermeasures are brought forward for mitigating N pollution in water bodies in this region.
