    • Methods and apparatus for controlling fecal odors in an enclosed space, such as a pit latrine, include providing an oxidizer, such as a catalytic heater and an optional mechanical ventilation unit, such as an inline fan, both flow connected to a vault (pit) of the latrine. The heater is also connected to a source of fuel, for example, propane. Fresh air is drawn through vents in the latrine housing and thereafter through toilets in the latrine and through the vault, providing oxygen for the reaction. The fan and/or oxidation process draws both fresh air and accompanying odorous compounds directly from the latrine and into the oxidizer wherein the odorous components are substantially destroyed.
    • 用于控制封闭空间(例如凹坑厕所)中的粪便气味的方法和装置包括提供氧化剂,例如催化加热器和可选的机械通风单元,例如在线风扇,两者都连接到拱顶(凹坑) 的厕所。 加热器也连接到燃料源,例如丙烷。 新鲜空气通过厕所内的通风口吸入,之后通过厕所内的厕所,并通过拱顶,为反应提供氧气。 风扇和/或氧化过程直接从厕所吸入新鲜空气和伴随的气味化合物,并进入氧化剂,其中恶臭组分基本上被破坏。
