半定量综合指数法在某生活垃圾焚烧厂风险评估中的应用

Application of semi-quantitative comprehensive index method in occupational health risk assessment in domestic waste incineration plant

摘要

摘要:
目的探讨半定量综合指数法在生活垃圾焚烧行业职业健康风险评估中的适用性。
方法选择某生活垃圾焚烧厂的烟气净化系统作为研究对象，采用GBZ/T 298—2017中推荐的半定量综合指数法对其运行过程中存在的主要化学有害因素进行职业健康风险评估。
结果烟气净化系统中氯化氢、二氧化硫、活性炭等3种有害因素的职业健康风险等级为低风险，铅及其化合物、镉及其化合物、氨、氢氧化钠4种有害因素的职业健康风险等级为中等风险。
结论半定量综合指数法的评估结果基本符合该生活垃圾焚烧厂烟气净化系统的职业健康风险现况，可为企业采取职业健康风险管控措施提供依据。

Abstract:
ObjectiveTo explore the applicability of semi-quantitative comprehensive index method in occupational health risk assessment in domestic waste incineration industry.
MethodsThe flue gas purification system in a domestic waste incineration plant was selected as the study subject. The risk assessment of chemical hazards were conducted using semi-quantitative comprehensive index method in the “Guidelines for occupational health risk assessment of chemicals in the workplace” （GBZ/T 298—2017）.
ResultsThe occupational health risk levels of hydrogen chloride， sulfur dioxide and activated carbon were low while using flue gas purification system， while the risk levels of lead and lead compounds， cadmium and cadmium compounds， ammonia and sodium hydroxide were medium.
ConclusionThe assessment results of semi-quantitative comprehensive index method are basically consistent with the current situation of occupational health risk of flue gas purification system in a domestic waste incineration plant， which can provide the basis for enterprises to take occupational health risk control measures.
