Evaluación de las emisiones de H2S, NH3 y compuestos orgánicos volátiles en la PTAR el salitre a través del régimen climático de Bogotá

Abstract

The offensive odours are a social problem because it affects the health and quality of life of the population that lives near to their emission sites. Given this situation, regulatory standards have been established for the control and management of gases emission in industries, so it is important to quantify the gases emitted in areas nearby urban populations, to establish possible control systems and fulfil legislation. In this work, H2S, NH3 and volatile organic compounds (VOCs), emitted in the wastewater pre-treatment area of the El Salitre Waste Water Treatment Plant (WWTP) in the dry and rainy seasons, were quantified using a portable gas detector. It was observed that the emission of gases is directly related to the daily rainfall, thus the dry season showed the highest concentrations of H2S, VOCs and NH3. In the dry season, a daily variability in the concentration of gases was also observed, with a higher gases concentration during the night period. These results will allow formulate strategies for the control and elimination of odours that are adapted to the emission conditions of the WWTP.
