Permeability Optimization Selection of Adsorbent Zeolite in Landfill Leachate Treatment

Seven different types of adsorbent were carried on the analysis through Buchner funnel filtering method,considering the seven kinds of media on adsorption effect of COD in leachate,ammonia nitrogen,lead,cadmium,chromium,arsenic,mercury,and considering the influence factors of particle size of filter media,filtration speed. Using4 filter as the best filtration adsorption the adsorption material,its COD value was about 10. 5 mg / g,the ammonia nitrogen adsorption value was about 2. 65 mg / g,the adsorption of lead was about 0. 20 mg / L,the cadmium adsorption value was about 0. 05 mg / g,the adsorption of chromium was about 4. 10 mg / g,the arsenic adsorption value was approximately3. 05 mg / g,mercury adsorption value was approximately 0. 72 mg / g.
