In this work, in the anaerobic digestion of effluent from wastewater treatment plant (WWTP) of paper pulp mill has been studied, because they contain organic carbon. The biogas production at the WWTP of Kenitra varies from a day to another depending on the concentration of organic carbon rate present in the effluent. For that reason, the effects of the initial organic carbon contained in effluent on the biogas production during anaerobic digestion have been simulated. Therefore, the production of biogas is estimated by using different input, assuming that the initial organic carbon rate in the effluent varies from zero to 5kg/m3 and by using the proposed approach by the mathematical model that describes the real behavior o f the digesters. Results have showed that the biogas production increases as a function of carbon organic rate up to 2.5kg/m3, then it tends to stabilize. The stabilization of biogas production observed above 2.5kg/m3 might be correlate with reactions occurring during hydrolysis, acidogenesis and methanogenesis steps.xad [ABSTRACT FROM AUTHOR] |
