Fluctuation Characteristics of Wastewater Discharged from Detached Houses and a Method for Their Analysis

Abstract

Fluctuation characteristics of wastewater discharged from households were evaluated, and a method for analyzing the fluctuation was proposed. In addition, the analyzed results were confirmed using a structural modified system. Intensive discharge of wastewater was concentrated in short periods, especially, when washing clothes, washing dishes, and cleaning the bath tub. Fluctuation characteristics of wastewater discharge were analyzed by the queue technique to solve batch arrival problems. This method allowed simple estimation of the capacity of the temporary storage chamber, and the flow equalization ratio of 1.5〜2.0. By installing the chamber, a fluctuation of wastewater discharge could be reduced to 1/4〜1/7.
