摘    要:选择河北省、河污灌区和府河污灌区为研究对象,对污灌水质和土壤环境质量进行了评价。结果表明,府河、汶河两大纯排污河的水质指标中重金属并未超过《农田灌溉水质标准》,经过20年的污灌,典型区的土壤中Cd超过我国《土壤环境质量标准》的二级标准。以当前2条排污河水进行灌溉,将会造成土壤中As的积累,应采取措施进行控制。

关 键 词:污水灌溉  重金属  土壤  定量估算

Abstract:The Irrigated areas by Wastewater of Xiaohe River and Fuhe River in Hebei province were chosen to assess both the quality of wastewater and the soil environment. The results indicated that heavy metals in both Xiaohe River and Fuhe River were not higher than that in Water Quality Standard for Farmland Irrigation. After about 20 years of irrigation, the accumulated Cd in the soil was found to be slightly higher than the second grade of National Soil Environmental Quality Standard. In addition, however, using Xiaohe and Fuhe river water for irrigation on land may lead accumulation of As in the studied soil.
Keywords:wastewater irrigation  heavy metals  soil  quantitative analysis
