| Until recently, nearly all sewage treatment-related regulations and researches have focused on the removal of the conventional and toxic pollutants from liquid effluents. The discharge of toxic compounds to the atmosphere has been implicitly regarded as a way of removal or destruction. During sewage treatment, the fate mechanism of volatilization/stripping, sorption and biotransformation primarily determines the fate of volatile HAPs. The objectives of this study are to investigate the emission characteristics of HAPs, which are generated from the liquid surface of sewage treatment facilities, by using an emission isolation flux chamber. HAP emissions increased at the inlet of the aerobic chamber during summer due to the relatively high atmospheric temperature. The percent ratio of flux for toluene reached its peak in winter, accounting for 33.6–34.2% of the total, but decreased to 25.1–28.6% in summer. In autumn, trichloroethene (TCE) was the highest, recording 17.6–18.1%, with chloroform and toluene showing similar levels. It seems that the ratio of chlorinated hydrocarbons increases in both summer and autumn because the chamber temperature during that time is higher than winter. This study is the initial study to investigate the emission characteristics of volatile HAPs emitted from domestic sewage treatment facilities to the air in Korea. Therefore, the isolation flux chamber will be used as an emission estimations tool to measure HAPs from sewage treatment facilities and may be applied to develop the emission factor and national source inventory of HAPs. |

| 现在为止，几乎所有与污水处理相关的法规和研究都集中在液体中常规及有毒污染物的去除方面。将有毒化合物排放到大气中已逐渐被视为排除或销毁的方式。污水处理过程中，一定的挥发/剥离，吸附和生物转化的机理决定了HAPS的结果。本研究使用一个隔离的排放通量室，通过研究污水处理设施产生的排放液的表面特性，从而达到调查HAPS的目的。夏季由于气温相对较高，HAP的排放量在有氧室的入口处增加，在冬季，甲苯在通量中的比例为33.6-34.2％，达到峰值；但在夏季下降到25.1-28.6％。在秋季，三氯乙烯（TCE的）含量最高，为17.6-18.1％，与氯仿，甲苯含量相当。无论在夏季或秋季，由于温度都比冬天高，氯化烃在通量中的比例也会增加。本研究初步调查了从韩国生活污水处理设施排放到大气中的挥发性HAPS的排放特性，隔离通量室将被用作排放估算工具来测量污水处理设施产生的HAPS，也许可用于开发排放因子和HAPS的国家来源清单。 |
