Estudio de la remoción de materia orgánica en el tratamiento de aguas residuales urbanas por medio de un filtro biológico a partir de lombrices californianas (Eisenia Foétida).

Abstract

This study presents how a worm has recently been presented in recent years as this technology is investigated nationally and internationally. In the removal of organic matter in the treatment of urban wastewater the parameters made (temperature, pH, turbidity, color, BOD, COD, suspended solids, total suspended solids, volatile suspended solids, fecal coliforms, total coliforms and among others), its purification has been very efficient for the treatment of them. Due to different studies the biological filter from E. Foétida is very economical for small populations where its budget is not essential to build a conventional plant. Because of this, a biofilter is a sustainable alternative to reduce pollution of surface waters and thereby the health of the population and contribute to the environment. Corresponding to the research carried out, different authors and applications of this system. Concepts related to wastewater treatment, the operation of the California earthworm and how effective the Tohá system for the removal of Asian organic matter with a BOD percentage of 95%, total solids 95%, 93% of suspended solids were obtained volatile, 80% oils and fats, (60-80) % of total nitrogen, (60-70) % of total phosphorus and fecal coliforms of 99%.
