Rediseño del sistema de tratamiento de lixiviados del Botadero Curgua del Cantón de Guaranda, provincia Bolívar.

Abstract

It was redesigned the Treatment System of Leachates generated in the Curgua Boundary of Guaranda Canton, Bolivar Province with the purpose of reducing the pollutants of this leachate and be able to be discharged to Guaranda River with parameters that comply with the Standard established by the TULSMA 2015, Book VI, Annex 1, Table 10. It was done the physicalchemical characterization and microbiology using HACH and Stablished Methods Manual for the

Analysis of Drinking Water and Residuals. Once the respective analyzes were carried out and the

results obtained,

it was detected that certain parameters are outside the Standard, among them there are: Color 1035 UTC, Turbidity 646,77 NTU, Conductivity 1277,86 uS/cm, pH 8,91, Total Suspended Solids 275,4 mg/L, Total Nitrogen 58,79 mg/L, Fluorides 15,11 mg/L, Chromium 0,575 mg/L, Cyanide 0,29 mg/L, Barium 2,64 mg/L, DBO5 745,815 mg/L, DQO 1229,465 mg/L, Total Coliformes 1364,00 NMP/100 mL. The efficiency of these treatments were established, now the parameters outside the Standard were within the limits given the following values: Color 1,00 UTC, Turbidity 0,49 NTU, Conductivity 215,66 uS/cm, pH 7,065, Total Suspended Solids 48,885 mg/L, Total Nitrogen 19,00 mg/L, Fluorides 4,025 mg/L, Chromium 0,017 mg/L, Cyanide 0,0085 mg/L, Barium 1,145 mg/L, DBO5 32,00 mg/L, DQO 49,00 mg/L, Total Coliformes 1,00 NMP/100 mL; with an average removal rate of 82,86 %, complying with the Norm and allowing its discharge to a body of fresh water. The Redesign of the System will verify with processes such as: channel, grille, degreaser, agitator tank, anaerobic filter of upflow and drying season. It is recommended to periodically carry out the physical, chemical and microbiological characterization of the leachate discharge to obtain real data that allows us to control the good functioning of the Treatment System, verifying that it complies with the current established Norm.
