Evaluation of Heavy Metal Pollution in Soil of Xiaodian Sewage Irrigation Area in Taiyuan
摘要
Abstract
Sewage irrigation is an effective way to alleviate the shortage of irrigated water and recycle municipal sewage. A series of scientific, social and economical problems caused by sewage irrigation, such as environmental, food security and sustainable development etc. , are getting more concerns. The soil of freshwater irrigated farmland in piedmont of Xiaodian district is chosen as the control spot. The content of the seven heavy metals in control spot is used as the assessment standard. The soil in the depth of 0~20 cm, 20~40 cm, 40~60 cm, 60~100 cm is evaluated. Five grades (security, warning, light pollution, median pollution, serious pollution) are classified according to the assessment results. Therefore, the pollution status evaluation of the soil and wastewater is of great significance on guiding the scientific management, reusing for municipal sewage, rational allocation of resource and crops security.关键词
