摘要
采用Airpak软件对青海省某乡村公共厕所进行建模分析,通过改变机械通风形式、排风口高度和换气次数,对该厕所室内臭气分布进行分析研究。结果表明上分散送风+下分散排风方式的臭气排除效果最好,排风口高度宜取0.3m,最佳换气次数为10h-1。
Airpak was used to model and analyze a rural public toilet in Qinghai Province, and the indoor odor distribution of the toilet was analyzed by changing the mechanical ventilation form, the height of the exhaust outlet and the number of air changes. The results show that the odor removal effect of the upper dispersion air supply with lower dispersion air exhaust mode is the best, the height of the exhaust outlet should be 0.3m, and the optimal air exchange rate is 10h-1.
