Performance Evaluation Method for Drainage Piping Systems with Food Disposers in Actual High-Rise Apartment Houses(Environmental Engineering)

概要

Regarding drainage piping systems with food disposers in actual super high-rise apartment houses with a height 100m, results were acquired from the experiments for the initial performance evaluation before habitation as well as the running performance evaluation by drainage load prediction after habitation. The knowledge, which contributed to a performance test, was also acquired. Before habitation, the maximum number of 6 simultaneous units of garbage wastewater, bowl flushing water, etc. was loaded. The maximum and minimum air pressure values in pipes were checked in line with the performance criteria of SHASE-S, and the safety of the initial performance was also verified. After habitation, the maximum number of simultaneous drainages was predicted and it was found that the figure recorded at the time of the initial performance verification was satisfactory. Moreover, the running pressure values in 99% of the occurrence probability were acquired, and the safety of running performance was also verified. Furthermore, the relation between the house drain's water level as a drainage load index and the pressure was determined, and as a result of comparison of pre-habitation and post-habitation, it was confirmed that there was no significant performance deterioration caused by long-term use.
