The characteristics and behavior of the H2S pollution plume in the emission zone of spring water and wastewater are determined by a total of 120 readings of H2S in the air and 24 samples of dissolved gas analysis during the observation period. Monitoring data is adjusted to determine the behavior of air pollution plumes and their relationship to emission sources by using statistical techniques and spatial analysis. The value of H2S emissions to the atmosphere was 6.62 kg/year by an emission factor of 0.0055 mg/s. The study revealed an important correlation between the continuous emission of H2S and its sources from springs and wastewater that is explained by exponential relation Fit (Y = a ebX), [H2S concentration. In air (mg/1000 cc)] = 0.00015 exp {0.0107 (H2S conc. In water mg/l)}. The spatial distribution maps of H2S showed that 38% of Hit's space is exposed to H2S concentration under the influence of the unpleasant odor, eye irritation, and corrosion in infrastructure parts (air conditioning apparatus). The characteristics of the H2S pollution plume, which were reflected in the behavior of H2S distribution of the exposed area, varied due to the variation of dispersion processes resulting from wind speed change. The concentration of H2S was 11.6 times when the wind speed decreased by 15.7 times. The wind speed affected the results of the mechanical dispersion coefficient in a positive relationship. Vertical and horizontal mechanical dispersion values in unstable weather conditions increased by 192 times and 243 times than in extremely stable weather conditions.

从伊拉克-伊拉克的活性硫化物-焦油泉释放的硫化氢羽流的表征和行为

在观测期间,通过总共120个空气中H 2 S读数和24个溶解气体分析样品,确定了泉水和废水排放区中H 2 S污染羽流的特性和行为。通过使用统计技术和空间分析,对监测数据进行调整,以确定空气污染羽流的行为及其与排放源的关系。大气中H 2 S的排放值为6.62 kg /年,排放因子为0.0055 mg / s。该研究揭示了H 2 S及其从泉水和废水中连续排放源之间的重要关联,这可以通过指数关系拟合(Y = ae bX)来解释,[H2 S浓度。空气中(mg / 1000 cc)= 0.00015 exp {0.0107(水中H 2 S浓度mg / l)}。H 2 S的空间分布图显示,在令人讨厌的气味,眼睛刺激和基础设施部件(空调设备)腐蚀的影响下,Hit的38%的空间暴露于H 2 S浓度。H 2 S污染羽流的特性反映在暴露区域的H 2 S分布行为中,这是由于风速变化导致的分散过程变化而变化的。H 2的浓度风速降低15.7倍时,S为11.6倍。风速以正比关系影响机械扩散系数的结果。与极端稳定的天气条件相比,不稳定天气条件下的垂直和水平机械分散值分别增加了192倍和243倍。
