Evaluación del arranque y puesta en marcha del sistema de tratamiento de aguas residuales de una empresa tabacalera

the aim of this work is to evaluate the setting up of a wastewater treatment plant in a tobacco company. it was carried out through the identification of the factors that lead to an increase in the levels of nitrogen and phosphorus; the study of the equipment and units that make up the treatment plant; the characterization and analysis of the waters of the treatment process, the latter through the curves of the nitrogen and phosphorus level behavior; the calculation of the treatment system efficiency; and lastly, an evaluation to verify that the nitrogen and phosphorus levels upon leaving the system fulfill environmental requirements. this study was developed in the facilities of a tobacco company, located in camburito, aragua, in its wastewater treatment plant. among the most important conclusions obtained from the study of characterization carried out during the initial stage of stabilization of the plant, was that the failure to extract mud in the sedimentation cones was the main cause of the high ages of the mud, that ranged between 24 and 122 days, considerably above the design value of 10,5 days, and the nitrogen and dbo levels behavior during the month of march which showed that the implemented system to eliminate these parameters in its initial stage was being carried out under conditions for which it was designed: the obtained efficiencies of removal are 98,7 ± 0,2 % for the biochemical demand of oxygen, 92 ± 4 % for the chemical demand of oxygen; 60 ± 20 % for nitrogen and of 48 ± 18 % for phosphorus.
