新疆某焦化厂环境中氨与一氧化碳污染调查

Investigation on Ammonia and Carbon Monoxide in the Environment of a Coking Plant in Xinjiang

目的对新疆某焦化厂内环境中氨和一氧化碳进行检测,对其结果进行分析和评价,从而提出合理的预防措施和建议。方法根据国家职业卫生标准及相关规范进行检测和评价。结果行政办公室氨和一氧化碳的合格率为100%;炼焦单位的炉顶的检测点空气中一氧化碳浓度在77次测定中有1次超标,其合格率为98.7%;除炉顶之外的其它四个监测点合格率为100%。结论行政办公楼、测温区的氨与一氧化碳所带来的风险可以忽略不计;该厂的工艺技术较先进,炼焦单元工作场所符合国家要求,其产生的危害因素浓度的大小受其产量的影响较小,但是受该车间的通风量的大小较大,在工作中需要保证充足的通风量。

Objective To detect, analyze and evaluate the concentrations of ammonia and carbon monoxide in the environment of a coking plant in Xinjiang, and put forward preventive measures and suggestions. Methods The analy- sis and evaluation were based on the national occupational health standards and relevant specifications. Results The concentration of carbon monoxide in only one of 77 monitoring samples collected from the top of coking units was found exceeding the standard limit and the qualification rates were 98. 7%, while in other monitoring points the qualification rates were 100%. Conclusions Because of the advanced technology in this plant, the risk in administrative office building and temperature measuring zone caused by ammonia and carbon monoxide could be neglected; the environment in the workplace of coking units could meet the requirements of national standards, the concentrations of hazard factors affected by productive activity was low, but the concentrations of hazard factors could be affected by the ventilation rate in workshop, therefore, ensuring adequate ventilation rate in workplace was needed.
