Diseño de una planta de tratamiento de Lixiviados para el botadero de Curgua del cantón Guaranda provincia de Bolívar.

Abstract

Leachable treatment plan desing for the rubbish dump in Curgua, Guaranda canton, Bolívar province was carried out in order to reduce the river pollution which is near and give a better quality of life to the dwelers of the sector. Leachable samples from Guaranda riverbanks were taken for 4 weeks to make physic-chemical and microbiological characterization tests by using method manual HACH. When analysis finished, it was detected that parameters such as DBO5 , DQO, Turbity , Color, Conductivity, Total Nitrogen, Flourides, Chlorides, Cyanides, Barium and Dissolved Oxygen are not according to the established norms in Unified Text of Secondary Legislation of the Environment Ministry in 15% of high concentration. From the developed analyses, leachable treatment plan with unit processes and operations like Grit chamber, UASB Reactor, a biological trickling filter, flocculation basins, sedimentation tanks and a tank to disinfect with an accurate dosage of coagulants was designed. By implementing this treatment plan, a leachable with low chemical concentrations will be gotten with the following results: 86.2 mg/L of DBO5 , 183.80 mg/L of DQO, Turbity 50 NTU, Color 70 UTC, Conductivity of 168.45 uS/cm, Total Nitrogen of 6.0 mg/L, Flourides of 2.23 mg/L, Chlorides 306.62 mg/L, Cyanides 0.06 mg/L, Barium 0.36 mg/L and Dissolved Oxygen of 7.92 mg/L to comply with the norms and pour to any body of freshwater. By using this treatment system, the liquids will not pollute to the environment but benefit the city`s development so that water will be able to be used for agriculture. It is recommended that Descentralized government of Guaranda city make the treatment plan work and execute to reduce the environmental impact.
