הוספת תג | סיכום: | The landfill of Yantzaza city is located in the Chimbutza parish, Yantzaza Canton, Province of Zamora Chinchipe. It contains an area of 4.8 hectares for the final disposal of solid waste, it has two cells: provisional cell is currently closed and the final disposal cell. Since its operation is generating leachate that are pretreated by trickling filters and finally, in a lagoon by the biological treatment process phytoremediation with German grass (Echinochloa polystachya). The main purpose of this research was to evaluate the treatment capacity of decontamination in the leachate generated in the landfill Yantzaza Canton through the process of phytoremediation with the species German grass (Echinochloa polystachya) and hyacinth water (Eichhornia crassipes). For this, first, thirteen parameters was characterized of the results of the latest analysis of the leachate generated in the landfill, then the largest phytoremediation potential was investigated between vegetable species German grass (Echinochloa polystachya) and water hyacinth (Eichhornia crassipes) for the treatment of leachate generated from the landfill pit provisional, through the building of two experimental pools to which was deposited a representative flow rate (0.01 liters / seconds) of the total leachate generated in the pit, and the respective vegetable species were planted. The timeframe set to the research process was four months at the end of the third month, it was set a time of admission and retention of leachate in experimental pools, three samples was collected: the first was taken the leachate before entering experimental pools, the second was taken from the leachate leaving the pool with German experimental grass (Echinochloa Polystachya) and the third was taken the leachate treated in the experimental pool with hyacinth water (Eichhornia crassipes). The results of the laboratory were processed through the statistical model chi-square (X2), where it was found that the hyacinth water has greater potential phytoremediation against to the German grass between fourteen parameters analyzed in the leachate object of this study. four parameters (Chlorides, Total Nitrogen, Total Solids and Sodium) have been treated with higher income from water hyacinth and three parameters (chemical oxygen demand, Iron and Total Hardness) have been normally treated with the German grass, three parameters (alkalinity, biochemical oxygen demand and potential Hydrogen) have had no effect in two experimental phytoremediation pools, and two parameters (Lead and Mercury) did not have variation in the results of the three samples; for the Sulfate parameter of assimilation was similar in the treatments for Phenols, there was not assimilation parameter, so its content increased in the treatments. Finally, a proposal was made to improve the final leachate treatment vegetables species with parameter water (Eichhornia crassipes). |
