污水在下水道网络中的运输会导致与硫化氢相关的潜在问题，包括气味滋扰、健康风险和微生物引起的腐蚀。这些问题发生的程度不仅取决于硫化物形成的速率，还取决于硫化氢排放到下水道大气中的速率。为了了解废水成分对排放过程的影响，对从下水道网络收集的生活废水进行了一些批处理实验。硫化氢在废水中的排放率调查被发现是约60%的去离子水的整体传质系数方面，导致在0.6的校正因子（α）。α因子在研究的湍流范围内没有显著变化（弗劳德数为0.04-0.23）。废水中硫化氢的亨利定律常数与去离子水中的接近，反映了一个修正因子（...
Transport of wastewater in sewer networks causes potential problems associated with hydrogen sulfide in regard to odor nuisance, health risk, and microbially induced corrosion. To what extent these problems occur depends not only on the rate of sulfide formation but also on the rate of hydrogen sulfide emission into the sewer atmosphere. To gain understanding of the influence of wastewater constituents on the emission process, a number of batch experiments were conducted on domestic wastewater collected from sewer networks. The emission rate of hydrogen sulfide in the wastewater investigated was found to be approximately 60% of that in de-ionized water in terms of the overall mass-transfer coefficient, resulting in a correction factor (alpha) of 0.6. The alpha factor did not change significantly within the turbulence range studied (Froude numbers of 0.04–0.23). The Henry’s law constant for hydrogen sulfide in wastewater was observed to be close to that in de-ionized water, reflecting a correction factor (...
