青岛市排水管理处近年发生两起多人中毒事故后,市府拨专款对全市十多个污水泵站进行了改造,安装了送、排风机和自动监测仪。为评价泵站的通风效果,选取两个有代表性的泵站进行了测试。因空气中的有毒组分通常含量很小,不易观测其变化,故采用加标法来测量。选择某种标记物,人工雾化,在不同时间、不同采样点采样,气相色谱法检测。 Qingdao City Drainage Office in recent years, after two cases of poisoning occurred in many people, the municipal government allocated special funds to the city’s more than 10 sewage pumping station has been transformed, installed to send, exhaust fan and automatic monitor. In order to evaluate the ventilation effect of pumping stations, two representative pumping stations were selected for testing. Due to the air is usually a small amount of toxic components, not easy to observe the changes, so the use of spike method to measure. Select a marker, artificial atomization, at different times, different sampling points, gas chromatography detection.
