| 摘 要： | 为控制城市生活污水排水管道中由厌氧微生物而产生的H2S所引起的恶臭味,应先对产生恶臭味的H2S气体进行监测,了解污水排水系统H2S的产生特性.对学生宿舍区、居民区和餐饮区中3个检查井的H2S溢出浓度进行现场监测,其结果通过Boltzmann函数的拟合回归分析以及正态分布的P-P图预测,表明城市生活污水排水管道中H2S的溢出与时间具有较大的相关性,随时间的变化符合二项式时间曲线估计的回归;其溢出浓度近似服从于正态分布;在同一天里,随着流速增加,H2S浓度越高;不同污水中H2S的浓度明显不同.这些特性为城市污水排水管道中所产生的H2S而引起的恶臭味的控制与治理提供依据.

| Abstract: | In order to control the odours caused by H2S produced from anaerobic microorganism in sewers,measurement should be made firstly,and the characteristics of H2S produced in sewers should be understood.In this paper,the concentration of H2S in field manhole including dormitory,residential and mess hall was monitored.The results indicated that H2S spilled from sewers had the characteristic of period,and subjected to quadratic curve estimation and normal distribution approximatively by fitting of Boltzmann function and analyzing of regression analysis.In the same day,with the flow velocity increasing,the concentration of H2S was higher.Different H2S concentration was engendered in different sewage.These characteristics could improve the foundation for controlling and administering the odours caused by H2S in sewers. |
