污水处理系统恶臭气体的产生及微生物法处理(上)

Biological Removal of Odor Gas Emitted from the Wastewater Treatment System(Ⅰ)

讨论了废水处理系统中恶臭气体的产生，并对用微生物法处理进行了研究。在某大厦的实际装置运行表明，对所逸出 H2S的处理效率可以达到 89％左右，使出口浓度在 3.0μ g· m－ 3以下；对所逸出的 NH3处理效率在 62.9％，出口浓度在 68.0μ g· m－ 3以下。总硫处理效率在 59.2％，出口浓度在 183.5μ g· m－ 3以下。

Emission of the odor gases from the waste water treatment system was discussed and treatment with microorganisms was studied. Practical treatment shows that the removal efficiency of emitted H2S was 89％ with the outlet concentration below 3.0μ g· m－ 3, NH3 was 62.9％ with the outlet concentration below 68.0μ g/m3, total sulfur compound was 59.2％ with the outlet concentration below 183.5μ g/m－ 3.
