Thermal hydrolysis of municipal solids can result in the production of non-biodegradable organic nutrient fractions that are not effectively treated with conventional sidestream and mainstream treatment processes

摘要

Utilities managing treatment facilities that need to meet enhanced nutrient and organic removal limits (TN < 3 mg/L and TP < 0.18 mg/L; COD < 10 mg/L) will need to consider additional treatment for the non-biodegradable organic nutrient fractions. In this study, sidestream treatment of the non-biodegradable nutrient pool was tested using ozone or electrocoagulation.
