A Study on Tests and Evaluation Methods of Odorant Removal Performance for a Urinal Toilet Unit with Deodorization Devices (Part 3), An Investigation of Odorant Emissions in the Toilet Space

摘要

The purpose of the present study is to estalish an evaluation method for a toilet unit with an air cleaning device, and then to investigate the proposed evaluation method by using a field survey. Odorant concentration in the restroom decreases with ventilations, an odor measuring instrument chamber was installed around a urinal toilet stall. The background ammonia concentration was ranged from 0[ppm] to 1446 [ppm] with urination acts, The background Methyl mercaptane was ranged from 0[ppm] to 0.0081 [ppm]. These results can be served as reference information for modeling indoor odorants released from human wastes in the toilets.
