Study on Estimation of Biological Dissolved Rate for The Crushed Garbage Using a Disposer

Abstract

For the purpose to designing the disposer wastewater treatment system for condominiums, the biological dissolved rate for the crushed garbage was measured. The garbage was treated as the anaerobic, aerobic or intermittent aerobic condition respectively. The order of the dissolved rate was aerobic > intermittent > anaerobic under the condition of 15 and 25°C. The residual after the 30d treatment for aerobic and intermittent treatments was about 26% and consisted of cellulose and inorganic particles such as eggshell and bone. Using the measured dissolved rate value, the performance of continuous feed garbage dissolving reactor was estimated. The estimation was found to agree well to the measurement.
