关中地区陶瓷行业VOCs排放系数测试与校正研究

Research on VOCs Pollutant Discharge Coefficient of Ceramic Industry in Guanzhong Region

挥发性有机物是大气污染物监测的新指标,污染物排放系数的确定是污染源清单编制的基础和重点。结合陕西省关中地区陶瓷行业特点,分建筑陶瓷、工艺陶瓷和建筑砖瓦三种类型对VOCs排放系数进行测试分析。结果表明,以非甲烷总烃计算,关中地区陶瓷行业三种类型VOCs排放系数为0. 009 2~0. 056 g/kg产品,远低于国家发布的挥发性有机物各类源排放系数中建筑陶瓷的排放系数。建议国家相关部门在挥发性有机物排放核算中结合实际情况,校正陕西省关中地区陶瓷行业VOCs排放系数为0. 01~0. 06 g/kg产品。

Volatile Organic Compounds （VOCs） is a new index in the air pollution monitoring. The pollutant discharge coefficient of VOCs is the basis of pollution calculation. For the ceramic industry of Guanzhong Region, there were three types of suchare building ceramics, artistic ceramics and brick tile ceramics. The test was done for the pollutant discharge coefficient of VOCs.Calculated in non - methane total hydrocarbon, the results showed that the pollutant discharge coefficient of VOCs in the ceramicindustry of Guanzhong Region, Shaanxi province was 0, 009 2 - 0, 056 g / kg, which was lower than the country,s pollutant discharge coefficient of VOCs. Combined with the actual situation, the pollutant discharge coefficient of VOCs in the ceramic industry should be corrected in the volatile organic compound emissions. The pollutant discharge coefficient of VOCs in the ceramic industry of Guanzhong Region should be adjusted to 0, 01 - 0, 06 g / kg according to the actual situation.
