Evaluation Effect of Passed Time on Garbage Leachate

The garbage leachate contains relatively large amounts of organic matter, plant nutrients, soluble salts as well as small amounts of some heavy metals that passed time can be affective on this parameters. we applied garbage leachate of organic fertilizer Isfahan factory in order to study effect of passed time on garbage leachate’s heavy metals and anions as split-split design with three replicates for each treatment during 4 months. Our treatment contain first tank ( tank’s original garbage leachate), second tank (diluted garbage leachate with water in ratio 1:5) and filter garbage leachate (we used sandy filter for garbage leachate) which analyzed in months of April, May, June and July. Analyzed parameters contained: anions (Cl, So4, HCo3), heavy metals (Cd, Cr, Ni and Pb), TSS, TDS and EC. Results suggested all of the parameters increased with pass of time.
