Impacto sonoro da estação de tratamento de esgoto do sistema central de Natal

Abstract

Currently, much of the sewage collected in Natal is sent to the Sewage Treatment Station of the Natal Central System, popularly known as ETE do Baldo. Due to the use of mechanized equipment such as the presence of pumps, blowers, centrifuges and power generators, noise is generated by this equipment that can impact the ETE's area of influence and cause inconvenience to the communities around it, thus the objective of this work to identify the possible sound adversities arising from the ETE do Baldo. The work consisted of the study of bibliographical references about the sound pressure levels transmitted in the urban space, as well as the legal parameters specified in the technical standard NBR 10151/2020. The collection of points in the vicinity of the ETE were carried out using a GPS, which were later inserted into the map of the location of the points, and using a Sonometer to measure the sound pressure levels, measured in decibels (dB), where from then on subsequent analyzes were carried out referring to the impacts produced by the same in the surroundings. It was identified that some points studied showed more significant results than others, thus it is necessary to adopt corrective actions and noise control measures in order to mitigate possible impacts.
