Análise da carga orgânica em uma área alagada existente no Campus Sede da Universidade Federal de Campina Grande.

Abstract

The aim of this study was to evaluate the organic load in a flooded area at the Federal University of Campina Grande – UFCG, through the analysis of organic matter concentration in water. An environmental investigation was conducted in the flooded area which receives industrial and domestic liquid effluents. Through the recognition of the surrounded area, the survey of activities carried out in the environment as potentials source of pollution and physicochemical characterisation of wastewater, it was possible to quantify the organic load in the flooded area. Consequently, it was possible to relate the effluent type and its origin in four analysed points. Analysis of parameters such as pH, dissolved oxygen (DO), biochemical oxygen demand (BOD5), chemical oxygen demand (COD) and temperature were carried out in the Sanitation Laboratory of Federal University of Campina Grande. The released pollutants had a negative effect on the water quality of the flooded area, mainly in reason of to the dissolved oxygen, where due to high organic loads it may have consumed the available oxygen, hampering the process of self-purification of the area. The analysed points suffer interference from outside effluents and effluents produced by the activities conducted at the University.
