煤化工企业污水处理VOCs污染特征及环境影响分析

Analysis of VOCs Pollution Characteristics and Environmental Impact in Wastewater Treatment of Coal Chemical Enterprises

为进一步探究煤化工企业污水处理区域中的挥发性有机物(VOCs)造成的环境污染问题,以西北地区某大型煤化工企业的污水处理区域作为研究对象,首先使用走航监测方法,对污水处理区域的VOCs组分及含量进行重点监测,明确其VOCs主要组分及含量,以对其污染特征进行初步评估;其次对该区域VOCs对臭氧和二次有机气溶胶的生成潜势进行计算分析,以初步明确VOCs对环境的影响。结果显示,烷烃、OVOCs、芳香烃三类VOCs的影响因素相对更为突出,在后续工作中应当予以重点关注。

In order to further explore the environmental pollution caused by volatile organic compounds(VOCs)in the sewage treatment area of coal chemical enterprises,the sewage treatment area of a large coal chemical enterprise in the northwest region was taken as the research object.Firstly,the aerial monitoring method was used to focus on monitoring the VOCs components and content in the sewage treatment area,clarify the main components and content of VOCs,and preliminarily evaluate their pollution characteristics.Secondly,calculate and analyze the generation potential of VOCs on ozone and secondary organic aerosols in the region,in order to preliminarily clarify the impact of VOCs on the environment.The results show that the influencing factors of alkanes,OVOCs,and aromatics are relatively more prominent,and should be given special attention in subsequent work.
