The poultry industry is a major source of odor pollution and has received significant attention because of its impact on air quality and human health. Acid scrubbing has been widely used in livestock houses to remove ammonia (NH₃), but this method has not been optimized for other odorous compounds, such as volatile organic compounds (VOCs). In this study, on-farm acid scrubbing equipment was operated in an experimental closed broiler house to determine the removal efficiency of gaseous pollution. The equipment was applied to the broiler exhaust system. The pH value and the gas residence time (gRT) were evaluated using central composite design and response surface methodology to establish a quadratic regression NH₃ removal model and to reduce emissions of VOCs and greenhouse gases under field conditions. The results showed that at gRT of 1.7 s and pH of 4.0 were the optimal process parameters. Under optimal treatment conditions, the NH₃ removal efficiency reached a maximum of 83.4%. Oxygenated VOC (OVOC) removal efficiency affected the removal of other components, such as hydrocarbons, aromatic hydrocarbons, and sulfides by dissolving into the organic aqueous solution. The results indicate that OVOCs might be the key factors influencing the removal of total VOCs. The removal efficiencies of acetaldehyde, dimethyl disulfide, methyl mercaptan, methyl sulfide, acetone, ethane, propane, and CO₂ under the optimal process were 90.6%, 69.5%, 81.7%, 100%, 97.5%, 84.3%, 70.6%, and 54.7%, respectively. The methane removal efficiency was undetermined because of the undetectable inlet concentration. This method can provide a basis for the application of acid scrubber equipment and technical support for collaborative treatment of gaseous pollutants in livestock houses.

家禽业是气味污染的主要来源，因其对空气质量和人类健康的影响而受到广泛关注。酸洗已广泛用于畜舍去除氨 (NH ₃ )，但该方法尚未针对其他有气味的化合物进行优化，例如挥发性有机化合物 (VOC)。在这项研究中，农场酸洗设备在实验性封闭肉鸡舍中运行，以确定气体污染的去除效率。该设备应用于肉鸡排气系统。使用中心复合设计和响应面方法评估 pH 值和气体停留时间 (gRT)，以建立二次回归 NH ₃去除模型，并减少现场条件下 VOC 和温室气体的排放。结果表明，在 1.7 s 的 gRT 和 4.0 的 pH 值是最佳工艺参数。在最佳处理条件下，NH ₃去除率最高可达83.4%。含氧 VOC (OVOC) 去除效率会影响其他组分的去除，例如碳氢化合物、芳烃和硫化物通过溶解到有机水溶液中。结果表明，OVOCs 可能是影响总 VOCs 去除的关键因素。乙醛、二甲基二硫、甲硫醇、甲硫、丙酮、乙烷、丙烷、CO _{2的去除效率}最优工艺下分别为90.6%、69.5%、81.7%、100%、97.5%、84.3%、70.6%和54.7%。由于无法检测到入口浓度，因此无法确定甲烷去除效率。该方法可为酸洗设备的应用提供依据，为畜舍气态污染物协同治理提供技术支持。
