Análisis comparativo de sistemas de tratamientos de lixiviados “recirculación y campo de infiltración” Yurak Casha 2014

Abstract

Leachate systems are comparatively analyzed in the process of re circulation and infiltration field in the landfill of the community Casha Yurack Canton Cañar, Cañar Province. The most appropriate technology is proposed for treatment of the type of leachate generated according to the characteristics of physical and chemical removal of contaminants and heavy metals in the leachate. Two techniques of anaerobic degradation were used allowing to reduce the organic load and heavy metals. For the test was run recirculation through a suction pump and a pipe diameter of 2 inches and length of 100 meters, it lasted two hours. The infiltration field is 200 meters at a depth of 0.5 meters, 0.1 meters in the ditch gravel and similary pipe covered with gravel o,1 meters thick was placed earth was placed to fully cover it. Analysis established that the best system for leachate treatment is acting infiltration field with 48,43% effective when removing heavy metals and organic load of leachate compared to its similar which is effective for removal of 17.81% Therefore we conclude that using any technique to decrease the values of contaminants in the landfill leaving an open criteria for further implementation. It is recommend a suitable treatment process for leachate and an suitable environment free from pollution of water resources and soils. This must be in accordance with environmental regulations and the corresponding technical and economic characteristics.
