Effiuent quality control in small Biological Process TreatingDomestic Wastewater

摘要

The problem of fluctuating in fluent flow and pollution concentration is a serious concern in small wastewater treatment plants.In this study,a simple mathematical simulation of an activated sludge process has been utilized to derive opera-rntional controls to stabilize process disturbance effects on effluent quality.The sensitivity of the model has been tested for several factors known to have significant variability with time and occasion.The variable factors were chosen from previous operational records of a small-scale process.The model was tested on a small process serving a university campusrnthrough extreme flow and pollutant conditions.Data collected during the applications of the controls was used to test therneffectiveness of the model.The results were encouraging.
