Background and objective: The research objective is to investigate the deep change rate of leachate quality parameters in soil containing nano-clay in the Agh Ghala composting plant. Methodology: The impact of clay presence on removal of leachate pollution was investigated. A pipe with a diameter of 10 cm and a length of 30 cm was filled with clay of composting plant. Then, an outlet valve was placed every 10 cm from the height of the soil. Type of soil and nano-clay percentage was expressed. Then, leachate was entered at a specific concentration and the results for the parameters TSS, TDS, BOD, COD, EC, pH in different columns were investigated to plot the recline rate. Results: Based on the analysis carried out in the first treatment of one percentage nano-clay, an efficiency of 62% was obtained. The second treatment of nano-clay had an efficiency percentage of 70% to 74%. The results of third treatment of one percentage nano-clay had removal efficiency of about 83%. Based on the results of the analysis in the first treatment of 5% nano-clay sample, the removal efficiency was about 74%, and it was 93% in the second treatment of 5% nano-clay. The results of the analysis of the third treatment of 5% nano-clay indicated a removal efficiency of about 98%. Conclusion: The results show the high impact of Montmorillonite mineral zeolite, which removal efficiency of 98% was obtained in leachate pollutant index parameters of the composting plant.
