Evaluación de la planta de tratamiento de aguas residuales Quillalli II de la parroquia Quisapincha, cantón Ambato, provincia de Tungurahua

Abstract

The present experimental work was carried out in order to determine if the Wastewater Treatment Plant "Quillalli II", is operating and meets the percentage of removal expected according to its design. The methodology was based on research from bibliographic sources, the topographic survey of the units that make up the treatment train of the Quillalli II WWTP, volumetric capacity of the flow of entry and exit of the plant was also carried out and samples of the wastewater were taken for a physical-chemical and biological analysis; which allowed to raise two proposals, the first which consists of improving the units of the treatment train to treat the wastewater that reaches the WWTP, while the second proposes the design of new units for another treatment train and thus treat an additional flow constituted by the waters coming from three neighborhoods "Turuloma", "Calvario" and "San Pedro". As main results it was obtained that the Quillalli II WWTP enters a maximum hourly flow of 1.19lt / sec, sanitary medium of 0.44lt / sec, for the WWTP to work correctly a screening and two T pipes were designed in the sedimentation tank, however, to add a new flow it is proposed: a screening, a sand trap and larger dimensions of all the units that make up the WWTP, with a budget of $131702.07, excluding VAT, for a period of five months. Additionally, a valid operation and maintenance plan was designed for the two proposals.
