This study investigated the advection and diffusion patterns of hydrogen sulfide (H₂S) in a prototype sewer network of a residential area in Xi'an, using Ventsim to simulate both natural and forced ventilation conditions. The results show that the simulated and measured values are within 10% difference, which confirms the reliability of the Ventsim simulation method. Forced ventilation increased the air velocity in sewer pipes by 8.8% compared to natural ventilation conditions. It was further found that utilizing only an intake or exhaust fan required 108s and 105s, respectively to completely expel hazardous gases from the sewage network. Simultaneous operation of both intake and exhaust fans significantly enhanced the migration rate of harmful gases, reducing the expulsion time to 55s. Nevertheless, using only an intake fan may cause H₂S to escape through small openings on manhole covers. These findings provide technical support for predicting and controlling hazardous gases within sanitary sewer networks, contributing to infrastructure safety and operational maintenance.

以西安某生活区污水管网为研究对象，利用Ventsim软件模拟预测了污水管道中硫化氢（H₂S）气体在自然和强化通风条件下的迁移扩散规律．结果表明，模拟与实测结果偏差小于10%，证明了Ventsim模拟方法的可靠性．相比于自然通风条件，强化通风作用下管段风速提高了8.8%，单一设置进气或排气风机有害气体完全排出污水管网需108和105s，同时设置进气和排气风机能够进一步提升有害气体迁移速率，有害气体排出污水管网需55s，仅设置进气风机会使H₂S逸散出检查井小孔．以上研究结果可为预测和控制污水管道中的有害气体以及管道安全运维提供技术方法支持．
