摘要
Abstract
Studying the effect of coal slag filling on soil arsenic content is of great significance for preventing and controlling soil heavy metal pollution.Through systematic sampling and analysis of the coal slag filling area,it was found that the coal slag filling significantly increased the arsenic content in the soil,and its migration and transformation characteristics showed a decreasing vertical direction with depth and a circular distribution in the horizontal direction.Based on experimental data and field investigations,a combined treatment technology system is proposed,mainly consisting of passivation solidification and supplemented by plant restoration.The research results indicate that the use of amendments for in-situ passivation and solidification can effectively reduce the bioavailability of arsenic,and the planting of arsenic tolerant plants can further enhance the remediation effect,providing technical support for the treatment of soil arsenic pollution in coal slag filling areas.关键词
