摘要:
城市污水泵站在正常运行过程中会产生难闻的恶臭气体,严重影响到周边居民的身体健康和生活质量. 为了有效控制集水池中恶臭气体的散发,需对其散发规律进行研究. 通过建立扩散传质数学模型,利用积分变化得出污水中恶臭气体浓度的解析解以及集水池房间的臭气浓度,分析讨论了室内换气速率、恶臭气体初始浓度、扩散传质系数、对流传质系数、分离系数等影响因素对臭气浓度分布、散发速率和散发量的影响. 研究结论可为污水泵站集水池臭气浓度的预测和控制提供重要的理论依据和求解方法.
Abstract:
In the process of normal operation,urban sewage pumping station produces unpleasant odorous gases,seriously affecting the health and quality of life of the surrounding residents. In order to effectively control the odor of gas emitted from the sewage sump,its distribution rules need to be studied. In this paper,by establishing the mathematical model of diffusion mass transfer,we obtain the analytic solution of the concentration of malodorous gas in sewage and the odor concentration in the sump chamber with the integral transform method. The effects of indoor ventilation rate,initial concentration of malodorous gas,diffusion mass transfer coefficient,convective mass transfer coefficient and separation coefficient on the distribution of odor concentration are analyzed and discussed. The conclusions of the study can provide an important theoretical basis and solution for the prediction and control of the concentration of odor in sump of sewage pumping station.
