USO DEL SUELO COMO TRATAMIENTO SECUNDARIO PARA LA REMOCION DE MATERIA ORGANICA DE LAS AGUAS RESIDUALES DOMESTICAS

Abstract

The present article was done to evaluate, the efficiency of removal organic matter in domestic wastewater generated at the Wastewater Treatment Plant "Ing. Arturo Pazos Sosa", using a modified natural soil conditions as a secondary treatment. We took 8 samplings to determine the BOD5 and COD, the average values for system imput were 398.55 mg/l of BOD5 and 681.25 mg/l of COD, reaching values of removal efficiencies of 99% to obtain an average value of 3.41 mg/l of BOD5 to the system output and standard deviation of 3.8mg/l. Removal efficiency of 98% of COD to obtain an average value of 12.5 mg/l to the system output and standard deviation of 13.25 mg/l, so it is concluded that such removal percentages are satisfactory. This article is part of research “Soil use as a secondary treatment of domestic waste water” by the MSc. Ivis Peralta and MSc. Wilber Pérez, and research results are shared with the MSc. Andy Alonzo.
