Abstract

This study aimed to provide the basic data to establish measures for the management of the public toilets and reduction of the offensive odor through the air dilution olfactory method and instrumental analysis about offensive odor dilution rate of public toilets, focusing on the Dong-gu, Daejeon Metropolitan City, Korea. The offensive odor intensities ranged from 10 degree to 669 degrees in the urinal toilets and from 31 to 464 in closet bowl toilets. Meanwhile, toilets that had offensive odor of more than 2.5, of which a civil complaint can be filed, were researched 6 (33%). Offensive odor intensities were different according to the closet bowl toilets of the flush, fermented and conventional methods and the year of their installation, but not according to the area of the toilets. As a result of the instrumental analysis targeting 6 public toilets to identify the offensive odor substance, the maximal concentration of $NH_3$ was 2.04 ppm and the average concentration was 0.67 ppm, but $H_2S$, $CH_3SH$ and $(CH_3)_3N$ were not detected. In the fermented and conventional public toilets were not soaps, air fresheners and wastebaskets. Just 50% of the flush toilets had toilet tissue.

본 연구에서는 대전광역시 동구를 중심으로 공중화장실에 대하여 악취강도를 공기희석관능법과 기기분석을 통하여 공중화장실관리 및 악취저감대책 수립에 기초자료로 제공하고자 하였다. 악취희석배수는 소변기실에서 10~669, 대변기실에서는 31~464까지 다양하게 나타났다. 한편 민원이 발생할 수 있는 악취강도 2.5도 이상의 악취가 발생하는 곳은 6개소(33%)로 조사되었다. 수세식 발효식 재래식처리방식의 대변기실과 설치년도에 따라 악취강도는 차이가 있으나, 화장실 면적은 차이가 없다. 악취원인물질 확인을 위한 6개 공중화장실을 대상으로 기기분석결과 NH3 최대농도는 2.04 ppm, 평균농도는 0.67 ppm이며, $H_2S$, $CH_3SH$, $(CH_3)_3N$는 검출되지 않았다. 발효식과 재래식공중화장실에는 비누, 방향제, 쓰레기통이 없었다. 화장지는 수세식 화장실의 50%에만 있었다.
