Wastewater Characterization of the Community "Antonio Maceo" of the Oriente University

Abstract

The main environmental problems of the Universidad de Oriente are associated with the emission of uncontrolled and untreated solid and liquid waste to the environment. In the university community "Antonio Maceo" 1 360 people now living, of which 70 % are students of the institution. This community poured about 23 462,7 L/d of wastewater residual liquids composed of 15 buildings and the waters of the kitchen and cafeteria. In this paper we evaluate the physico-chemical and microbiological wastewater university community Antonio Maceo, determining environmental parameters of highest incidence. The waters are neutral and proper salinity. They have gray color, odor and cloudy appearance, without the presence of floating material. The organic matter content is above discharge limits and detected total and fecal coli forms. The greatest variability (46,5 %) of wastewater depends on the turbidity, COD, BOD 5, sulfide, ammonium, oil and grease and total solids and fixed.
