Influencia de las aguas residuales de las lavadoras y tintorerías de la industria textil en las lagunas de oxidación en el cantón San Pedro de Pelileo.

Abstract

The present objective of this research work is to evaluate the influence of wastewater from washing machines and dry cleaners of the textil industry in oxidation lagoons, in San Pedro de Pelileo Canton there are approximately 45 of the 72 washing machines founds in Tungurahua province, according to the regulation for drinking water, and sewerage determined by the Government of the Autonomous Municipal Decentralized of San Pedro Pelileo, These identities must compulsorily perform two monitoring per year in February and the others in July - August, For the sample, a descriptive, non-experimental, cross-sectional model was carried out whit 41 washer samples. For the influence assessment, the correlational matrix was applied, reducing the relative parameters from 15 to 10 applying the total variance with a confidence level of 0.5, it was determined that three components formed by component 1 Chemical Oxygen Demand, Total Solids, Lead, Biochemical Oxygen Demand, Sulfates, in Component 2 It is composed of: Chromium, phenols, fats and Oil, in Component 3 It is composed of: zinc, concluding that the 3 Components have an influence of 20% in the oxidation lagoons at the time of discharges. In addition, it is recommended that the Municipal of GAD San Pedro de Pelileo perform a night monitoring in each in each washing machine, as well as in the oxidation lagoon also the chance in the regulation of drinking water and sewerage system to establish that the payment values of each washing machine are carried out by determining their pollutant load, respectively.
