摘要:
为了对硫酸制备过程中产生的焙烧炉渣和污泥等固体废物进行类别鉴定,用硫酸硝酸\|浸出毒性试验方法对某4个公司样品中的砷元素做了浸出特性研究.结果表明:以硫精砂为原料或部分含硫精砂为原料制酸工艺所造成的砷污染远大于以硫铁矿为原料的制酸工艺;污泥浸出液中,炉渣残渣粒径小于0.075 mm时砷含量最高可达36 mg/L;粒径在0.075~0.2 mm时砷含量最高达30 mg/L;粒径越小,砷浸出量相对越多.污泥浸出液中砷含量均远高于砷的浸出毒性限值浓度(5 mg/L)和污水综合排放标准中砷的限值浓度(0.5 mg/L),表明厂家未能严格执行“第一类污染物必须车间处理达标后外排措施”的要求,建议监管部门加强第一类污染物监控力度,切实落实相关法律法规.
Abstract:
Samples from four different companies were characterized by arsenic through leaching to classify solid wastes such as slag and sludge which were generated in the preparation process of sulfuric acid. Sulphuric acid & nitric acid\|extraction procedure for leaching toxicity method was used. The result shows that the pollution of arsenic generated in the preparation process of sulfuric acid using pyrite or part of sulfur concentrate as raw material is much more serious than using pyrite as raw material,the concentration of arsenic is up to 36 mg/L when the particle size of slag is smaller than 0.075 mm,while the concentration of arsenic is up to 30 mg/L when the particle size is 0.075 mm\|0.2 mm. It shows that the concentration of arsenic is higher when the particle size is smaller. The arsenic concentrations of samples from the four different companies are all higher than limited concentration of leaching toxicity (5 mg/L) and integrated wastewater discharge standard (0.5 mg/L), which indicates the four manufacturers fail to comply strictly the claim that the first class pollutants which are not purified up to standard should not be discharged.The regulatory authorities should strengthen monitoring of the first class pollutants, implement relevant laws and regulations practically.
