再生铅冶炼的土壤环境影响评价——以一再生铅冶炼企业10万吨废旧铅酸蓄电池项目为例

Impact Assessment of Remelted Lead on Soil Environment——Case Study of Waste Lead-acid Batteries Project with Capacity of 100,000 Tons

再生铅冶炼是对铅废弃物的循环利用,也是防治铅污染的重要手段,但如果在冶炼过程中处置不当,会引起土壤污染。以年处理10万t废铅酸蓄电池为例,根据铅排放浓度和排放量、在大气中沉降规律以及在土壤的累积规律,探讨了再生铅冶炼项目的土壤累积影响。

Remelted lead smelting is to achieve recycling of wasted leads as well as an important way to prevent lead pollution.However,inappropriate treatment in the smelting process may lead to soil pollution.This study takes a project with capacity of processing 10,000 tons of waste lead-acid batteries as an example and discussed cumulative effects of remelted lead smelting projects on soils according to the emission concentration and emission amount of lead,settlement rules in the atmosphere and accumulation law in the soil.
