Resumen
The aim was redesigning the treatment system of sewage water of the Slaughter Center of Guaranda city, in order to reduce the pollution it releases to Guaranda River and its inhabitants, due to the Flow of sewage water generated in the Slaughter Center; hence, the initial diagnosis to the systems was performed, through determining the caudal, gathering representative samples for the physical, chemical and microbiological characterization, evidencing so high levels of total solids with 2502,59 mg/L, total suspended solids with 331,94 mg/L, total nitrogen with 74,4 mg/L, fecal coliforms with 7432,75 mg/L, DBO5 with 751,10 mg/ L and DQO with 1229,21 mg/L, where such parameters exceed the permitted limits stated in the Ministerial Agreement 097 A from November 4, 2015, regarding the flow limits into a supply of fresh water, TULSMA reforming agreement, due to this characterization it was considered the redesign of the treatment systems if the Slaughter Center through the implementation of mesh strainers, a biological reactor SBR, secondary decanter, disinfection tank and drying bed, simulating those processes to laboratory scale where the following results were obtained; total solids with 26,98 mg/L, total suspended solids with 1,21 mg/L, total nitrogen with 30 mg/L, fecal coliforms with <1 mg/L, DBO5 with 18,34 mg/ L and DQO with 36,79 mg/L, causing a reduction of almost 94% and so accomplishing the regulation of the current norm. With the results obtained from the tests, the design of a treatment system was performed, with the dimensioning of the complementary units with mathematical calculation, using design criteria of different authors, so this study is recommended to be applied as soon possible for the benefit of the citizenship and the whole environment.
