Afegir etiqueta | Sumari: | The present research project evaluated the potential fitorremediador of two plant species through controlled conditions in leachate from the controled landfill in Zamora city. This took place the characterization of the study site, interviews work and search for secondary information. For phytoremediation process were developed experimental pools with their respective repetition (52 cm width, 115 cm long, 62 cm high), supporting a flow of 0,423 l/s per day. In addition 40 samples of the two species were pruned for control of growth reaching a final result in leaves; 90 and 78 cm and root; 27, 62 and 27 cm, (Chrysopogon zizanioides. (L.) Roberty) and (Eleocharis elegans. (Kunth) Roem. & Schult.) respectively. It was determined the potential fitorremediador using the Chi square statistical model, the species (Chrysopogon zizanioides. (L.) Roberty) reduced in greater proportion of contaminants in the parameters: Chemical Demand of Oxygen (COD) 128 - 88 mg/L; Solids Suspended Total 130-28 mg/L and metals such as Iron 10 - 3.3 mg/L, thus accepting the alternative hypothesis and refusing the null hypothesis respectively. With the objective of determining the pollutant shortage of pollutants in leachates analyzed leakage into the cell's disposal is searched, found once proceeded to carry out the analysis resulted positive concentration of contaminants with a 60% exceeding the permissible maximum limit established by the national environmental authority, in parameters; SST 1303 mg/l, ammonia nitrogen 505 mg/l, BDO 576 mg/l, COD 2400mg/l, iron 37mg/l, demonstrating the existence of contamination in the dump Controlled Landfill . |
