恶臭监测分析中若干问题的探讨

Discussion on Some Problems of Odor Monitoring and Analysing

从实际的恶臭监测分析出发,结合执行与实践《恶臭污染物排放标准》、《空气质量恶臭的测定三点比较式臭袋法》过程中的各种体会,从标准本身、采样以及分析的质量保证这三个方面,对恶臭监测分析中的相关问题进行了探讨。建议对排放标准的适用范围进行调整,增加行业排放标准,对有组织排放增加浓度排放限值进行规定,对采样气象条件、采样点位、采样频率进行明确,并引入背景值或本底值的测量,对测量结果进行修正。最后针对分析环节,就采样器材、实验室和分析人员三个方面提出了相应的质量保证要求,以确保恶臭测定方法的准确有效。

According to actual odor monitoring and analyzing,intergrating with several experiences in carrying out Emission standards for odor pollutants,Air quality-Determination of odor-Triangle odor bag method,some problems of odor monitoring and analysing were discussed from standards,sampling and analysis quality assurance.The suggestions were as follows：adjusting application range of emission standard,adding industrial emission standards and concentration emission limits in organized emission,definituding weather condition in sampling,sampling point,and sampling frequency,importing background value to correct measure result.Finally,some corresponding requests on analysis quality assurance were put forward to insure accuracy and availability of odor determination method.
