生活垃圾焚烧发电厂烟尘中重金属沉降对土壤环境影响分析

Analysis of the impact of heavy metal deposition in the dust of domestic waste incineration power plant on soil environment

本文以一日处理生活垃圾2250t的生活垃圾焚烧发电厂为例,根据其重金属的排放量,预测重金属随大气扩散、迁移,最终通过自然降水和自然沉降进入土壤后,对土壤环境的影响。结果表明,项目建成后的20年内,大气评价范围内土壤中重金属的累计值满足《土壤环境质量建设用地土壤污染风险管控标准(试行)》 (GB36600-2018)表1中第二类用地筛选值要求。

Taking one domestic waste incineration plant with the disposal capacity 2250 t/d as an example.According to the quantity of heavy metals in this project, With the heavy metal subsidence into soil to prediction the environment impact of heavy metal deposition on soil. Results show: 20 years after the completion of the project,the quantity of heavy metals in soil still meet standard requirements.
