چکیده مقاله
Today, sanitary landfill is one of the most common approaches for municipal solid waste disposal, but there is a major drawback, which is the production of highly contaminated leachate These leachates must be properly treated before discharging into the environment Landfill leachate contains highly toxic and resistant substances that are harmful to the environment and human health Therefore, the risk s of potentially harmful landfill leachate discharges to the environment must be assessed and measured to make effective choices regarding landfill leachate management and treatment The purpose of this research is to treat the leachate of the Urmia urban waste disposal site using pozzolan mineral this mineral has rich and accessible reserves all over the world and is considered an economical and efficient option for leachate treatment In this regard, the experiments of reducing the microbial load and leachate toxic elements by pozzolan in different sizes of absorbents were investigated to remove the pollution According to the results, in all of the experiments, the amount of ammonium reduction was more than 95% Also, bacterial culture using the method serial dilution in nutrient agar medium showed a decrease in the microbial load from 42 numbers in dilution 10−16 to 81 numbers in dilution 10−4 By reducing the size of the adsorbent, the value of the Biochemical oxygen demand parameter BOD has decreased by 94 3% Regarding the chemical oxygen demand parameter COD , the highest reduction of up to 95 9% is from a process similar to biochemical oxygen demand
