对双瓮漏斗厕所臭气浓度的监测表明，其氨、硫化氢、３－甲基吲哚等三种臭气浓度比旧式厕所有非常显著的减少，且与厕所的卫生管理水平有关。其臭气嗅觉强度主要由吲哚引起，在低浓度情况下用官能检查法非常灵敏；氨用仪器分析法测定比较简便，有一定代表性和实用价值。 The monitoring of odor concentration in the double urn funnel toilet showed that the concentration of ammonia, hydrogen sulfide, 3-methylindole and other three kinds of odor had a very significant reduction compared with the old one, and was related to the toilet hygiene management level. Odor intensity of the odor is mainly caused by indole, which is very sensitive to the function test method at low concentration. Ammonia instrument analysis method is relatively simple and has some representative and practical value.
