Development of Air Monitoring System for the Malodorous Facilities and Application into Environmental Education

为了机械地识别恶臭设施中的恶臭空气状况，我们研制了一种便于操作的便携式空气监测系统。这篇报告描述了我们在恶臭设施中定义了大气的恶臭程度，比如污水房。利用空气监测系统对恶臭物质中的乙酸和氨进行检测，恶臭度平均值均为0.07，为无气味的边界限。结果表明，利用计算机对数据进行处理是很方便的，该自动气味传感系统可作为混合恶臭气体样本的识别方法，具有实际应用价值。

In order to recognize mechanically the malodorous air condition in the malodorous facilities, we have developed an air monitoring system, which is a potable type to easyly carry out. This report decribed that we defined the malodorous degree of the atmosphere in the malodorous facilities, such as a sewage house. Acetic acid and ammonia of malodorous substances were detected using the air monitoring system, and then the averaged values of the malodorous degrees became both 0.07 as a boundary limiting at which smell isn't felt.It was found that the data treatment is facilitated by using a computer and the automated odor sensing system can be of practical use as a recognition method for mixed malodorous gas samples.
