A Study on Efficient Operation Management of Small-Scale Sewage Treatment Plants in Gyeongnam
박성환 Sung-hwan Park , 문성용 Sung-yong Moon
Abstract
In this study, It is to identify matter through the analysis of small-scale sewage treatment plant operations in Gyeongsangnam-do and relatively weak state facilities in winter. And It is suggested to appropriate management method at sewage treatment facilities. First, small scale sewage treatment plant treatment method is very divers. The selection of treatment method has not been made by appropriate standard. second, there are many problems that have been raised consistently such as inappropriate facilities operating ratio, sewage inflow of low concentration(less than BOD 100mg/L), inflow sewage low temperature(in winter) and inflow unknown water by uninstalled joints. Third, 12 facilities small-scale sewage treatment facilities the excess of effluent total nitrogen water quality standards(enhanced water quality in winter). Therefore, this study suggested that nitrogen and phosphate treatment efficiency improves when unification of sewage system, sealing of treatment facilities, maintenance of sewage treatment facilities pipeline and installed advanced process like total phosphate facilities.
