COD FRACTIONS IN MECHANICAL-BIOLOGICAL WASTEWATER TREATMENT PLANT
Journal Title: Civil and Environmental Engineering Reports - Year 2017, Vol 1, Issue 24
Abstract
The paper presents results of studies concerning the designation of COD fraction in the raw, mechanically treated and biologically treated wastewater. The test object was a wastewater treatment plant with the output of over 20,000 PE. The results were compared with data received in the ASM models. During investigation following fractions of COD were determined: dissolved non-biodegradable SI, dissolved easily biodegradable SS, in organic suspension slowly degradable XS and in organic suspension nonbiodegradable XI. Methodology for determining the COD fraction was based on the guidelines ATV-A 131. The real percentage of each fraction in total COD in raw wastewater are different from data received in ASM models.
