摘要
依据不同采样点污染物组分不同,分析各样品中氢、氧同位素组成比率,判断各采样点污染贡献率。研究以天津市北塘排污河为例,将其分为若干段,每一段作为一个箱式模型对流入和流出区段的溶解态氢、氧同位素比率进行检测,借助氢、氧同位素成分比率图求算各区段的污染贡献率,同时判断是否有新污染源增加,研究表明北塘排污河下游中心桥闸处污染贡献率最高,达到污染总量的70%,另外发现2个污染未知源,分别位于北塘排污河中游检测点和山岭子间、山岭子与永和闸间。
The contribution rate of pollution in each sampling point was determined by the analysis of hydrogen and oxygen isotopic composition ratio, according to different pollutant components based on the different sampling points in this study. The study area, the Beitang Sewage River in Tianjin, was divided into several sections, each section as a box-type model. Firstly, collected samples through the inflow and outflow of the box-type model and detected the hydrogen and oxygen isotope ratio; Secondly, calculated the pollution eontributionrate of each samples and the isotopic composition ratio of hydrogen and oxygen; then determined if there were new pollution sources. The result showed that there was the highest contribution rate by 70% of the total pollution in Zhongxinqiao Brake; at the same time, two new -discovered contamination source located between the middle section of the Beitang Sewage River and Shanlingzi, Shanlingzi and Yonghe Brake.
