| 摘 要： | 对广州大坦沙污水处理厂各工艺阶段污水中挥发性有机物(VOCs)的测试表明,进水中主要有害VOCs为苯系物和卤代烃;进水和出水比较,苯 甲苯、乙苯、二甲苯(合称BTEX) 的去除率接近100%,污水中几种主要卤代烃的去除效率范围为79%—89%.VOCs主要的去除作用发生在生物反应池,特别是厌氧阶段,本研究还对污水处理厂几种典型挥发有机物排放到周围空气中的量进行了理论估计,计算表明卤代烃进入空气中的比例高于BTEX.

| Abstract: | Volatile organic compounds (VOCs) in wastewaters from different stages in Datansha wastewa-ter treatment plant of Guangzhou were analysed, Monocyclic aromatics and chlorinated hydrocarbons (CHCs) were found to be the principal hazardous pollutants in influent. By the comparison of VOCs in the influent and effluent, it revealed that the removal efficiencies for benzene, toluene, ethylbenzene and xylene (BTEX) were almost 100%, and for several typical CHCs, 79%-89 % . BTEX and the selected CHCs were mostly removed in the bioreaction basin, especially within the anaerobic process. Emissions of hazardous VOCs to the ambient air were also estimated, and the calculation showed that a larger proportion of CHCs were removed by volatilisation than that of BTEX. |
