The objective of this experiment is to remove nitrogen and phosphorus from the wastewater by Daewoo Nutrients Removal(DNR) System.
The BOD removal rate in DNR, MLE and Oxidation ditch process is 91.4%, 91.5% and 90.2%, respectively which is shown similar trends in COD removal rate.
The removal rate of T-N in DNR, MLE and Oxidation ditch process is 55.5%, 57.4% and 41.9%, respectively. The removal rate of T-P in DNR, MLE and Oxidation ditch process is 62.5%, 35.1% and 32.8%, respectively.
DNR process is best in removal of T-N and T-P as well as organics.
