Phenol fate simulation for wastewater treatment plant by using ASM3+ model

Abstract

The growing population, urbanization and modernization has led to the release of toxic organic compounds into the environment, Phenol is one of the most common organic water pollutants, which is regarded as a priority pollutant by USEPA is a widespread pollutant found in many industrial effluents. To protect human health and ecosystems, the research of phenol-laden waste waters is of great importance. Literatures on biodegradation kinetics of phenol as individual pollutant is though plenty, study of phenol treatment in the wastewater treatment plant by using the ASM3 modeling in Korea has never been reported. Activated sludge model 3(Computer Program for the Identication and Simulation of Aquatic Systems)developed in 1999. As the biological reaction can be changed arbitrarily based on the user in Aquasim, simulating the new concept modeling is possibility. We add the phenol treatment process in ASM3 matrix. Using the average phenol concentration of all the wastewater treatment plants in Busan, we estimate parameters through the surface response methodology. The simulation of phenol in AQUASIM is operated successfully. The ASM3 model with the process of phenol treatment for the imitation of wastewater treatment is possibility. The proposed method will be useful to designers and operators of wastewater treatment plants, who need reliable kinetic parameters to predict the fate of toxic contaminants in wastewater treatment plants.
