Avaliação da estrutura da estação de tratamento de efluentes da cidade de Corrente - PI

Abstract

Treatment of sewage is important. Because Sewage Treatment Stations (ETEs) can be great sources of pollution. TEEs consume large amounts of water and energy, release harmful gases to the atmosphere, and produce solid wastes that are difficult to treat and dispose of such as sludge and water hyacinths. The objective of this article was to analyze the technical and structural aspects of Current - PI ETE. The methodology used in the survey of the Sanitary Sewage System was done through a field survey with photographic record, georeferencing of some points in the chosen area using a specific unit of the sewage treatment plant in the municipality of Corrente-PI, with photographic record, Interview and questionnaire application with the Agespisa de Corrente-PI employee. The implanted elevation stations are three, as are three stabilization ponds - totaling an area of 2.3 ha. The only treatment existing in the lagoons is photosynthetic. The municipality of Corrente has a sewerage network with a low number of household connections, with a coverage percentage of only 20%, and for the performance of the sewage treatment services in the city of Corrente it does not have license release records issued by Secretary of the environment (SEMARH). In this article, it is highlighted that the Corrente ETE does not meet the standards necessary to guarantee the quality of sewage treatment. The privilege of a city to get proper sewage treatment has to be with investment in the structure of the treatment plant which contribute to improvement in public health. In face of the existing treatment in the ETE, we can conclude that the sewage treatment activity generates important environmental impacts that deserve attention of the managers and the environmental agencies
