排污许可制度改革实施三年多来,通过各级生态环境部门的共同努力,改革成效显著,法律法规不断完善,技术体系初具规模,环境管理制度逐步衔接融合,环境主体责任初步明晰,分行业核发排污许可证有序推进。2020年是排污许可制实现固定污染源全覆盖目标年,生态环境部统筹全国推动开展固定污染源排污许可清理整顿,摸排"应发未发"的排污单位并分类处置,将固定污染源全部纳入环境监管范围。
浩瀚色谱（山东）应用技术开发有限公司结合环境监测工作的实际情况,探讨了固定污染源中非甲烷总烃(NMHC)监测的相关问题,提出了几点建议.固定污染源管道内温度较高时,使用HJ 38-2017方法采样后实验室分析的数据,不能较好的反映现场实际情况,建议制定现场分析非甲烷总烃的相关标准;同时分析非甲烷总烃,芳香烃类、酸脂类等对非甲烷总烃有贡献的挥发性有机物数据的情况,审核时应将各有机物数据折算以碳计后进行比较,同时还需考虑各类有机物对非甲烷总烃的贡献程度、取样方式、工况稳定性等因素;现场取样时要正确使用玻璃棉,避免对分析过程产生干扰和污染样品.

Over the past three years since the implementation of the pollution discharge permit system reform, through the joint efforts of the ecological and environmental departments at all levels, the reform has achieved remarkable results, the laws and regulations have been continuously improved, the technical system has begun to take shape, the environmental management system has gradually been integrated, the environmental main responsibilities have been initially clarified, and industry-specific responsibilities have been The issuance of pollutant discharge permits has been carried out in an orderly manner. The year 2020 is the target year for the pollutant discharge permit system to achieve full coverage of fixed pollution sources. The Ministry of Ecology and Environment will coordinate the nationwide promotion of the clean-up and rectification of fixed pollution source pollutant discharge permits, identify and dispose of "should have not issued" pollutant discharge units and classify them for disposal, and incorporate all fixed pollution sources into the scope of environmental supervision. .
Combining the actual situation of environmental monitoring work, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. discussed the problems related to the monitoring of non-methane total hydrocarbons (NMHC) in fixed pollution sources, and put forward some suggestions. When the temperature in the pipeline of fixed pollution sources is high, The data analyzed in the laboratory after sampling using the HJ 38-2017 method cannot reflect the actual situation on site. It is recommended to formulate relevant standards for on-site analysis of total non-methane hydrocarbons; For the data of volatile organic compounds that contribute to non-methane total hydrocarbons, the data of each organic matter should be converted into carbon for comparison during the review. At the same time, the contribution of various types of organic compounds to non-methane total hydrocarbons, sampling methods, and engineering methods should be considered. Factors such as environmental stability; glass wool should be used correctly when sampling on-site to avoid interference with the analysis process and contamination of the sample.
