Simulation studies the effect of temperature on the efficiency of the bioreactor with the participation of fecal sewage
The aim of the research was to study the effect of temperature on the efficiency of the bioreactor with the participation of fecal sewage. Simulation studies were carried out in the simulator developed in Canadian company Hydromantis – GPS-X, Version 5.0.
The design model of sewage plant consists of a circular primary clarifier, a plug flow tank (system MUCT) and two circular secondary clarifiers. I have used the library CNPLIB while simulation of the project in GPS-X. For describing wastewater influent from collector and wastewater transported from septic tank I have used the mathematical model TSSCOD. In the description of sedimentation in the circular primary clarifier and in the secondary clarifiers I chose the model Simple1d. I chose the model ASM2d to characterize the processes occurring in the bioreactor. When I was configuring objects related to the input, I was used spreadsheet included with the GPS-X, named Influent Advisor.
Examined six series of simulation, which differed by the value of the temperature in which processes of wastewater treatment was occurring and the participation of fecal sewage into the wastewater from the collector. Simulation studies were carried out at 10℃ and 20℃ without wastewater from septic tank and at 10% and 20% of their participation too. During the entire process of simulation the various parameter like composition and quality of sewage was maintained constant.
Analysis of the results of the simulations showed that lowering the temperature at which the processes of wastewater treatment was being carried out, affected the efficiency of
removal of impurities in the system. On the other hand, increase of the participation of fecal sewage in wastewater from the collector, improves BOD5 and COD removal efficiency, and at the same time worsens total nitrogen removal efficiency. Also I observed that during the entire activity of simulation efficiency of removal total phosphorus was better with 20% participation of wastewater transported from septic tank than it was with 10% participation.
