    Nitrogen Isotope Tracing of Sources of Nitrate Contamination in Groundwater from Wastewater Irrigated Area

    • 摘要: 为了识别石家庄市南部污灌区地下水硝酸盐污染来源, 采集5种潜在污染源和19组地下水样用于化学和氮同位素分析.灌溉污水NH4+δ15N值较低(4.0‰), 施化肥土壤和粪堆下土壤NO3-δ15N值分别为1.4‰和12.4‰; 仅施厩肥的蔬菜种植区下伏近30 m厚包气带沉积物NO3-δ15N分布显示, 来自动物粪便的NO3-已运移到11.5 m以下包气带, 均值10.9‰; 污水灌溉农田下伏厚层包气带沉积物样品分析结果指示, 土壤层下伏包气带沉积物δ15N值变幅较小, 均值5.7‰.污灌区内除一深井外, 其他水井地下水硝酸盐浓度变化在52.6~124.5 mg/L之间, 均值79.72 mg/L, δ15N值变化在5.3‰~8.3‰之间, 均值7.0‰.污灌区地下水的δ15N值较污灌区土壤层下伏包气带沉积物的δ15N值高, 表明地下水NO3-除了来自灌溉的污水外, 还有δ15N值更高的其他来源, 这些来源主要是人和动物粪便.利用线性混合模型计算, 污灌区地下水NO3-来自灌溉的污水, 约占76%, 而来自人和动物粪便的NO3-约占24%.为控制污灌区地下水NO3-浓度进一步增长, 不仅要加强污水灌溉管理, 还要加强人和动物粪便的管理.
