title: Advanced treatment of stabilized landfill leachate after biochemical process with hydrocalumite chloride (Ca/Al-Cl LDH).
abstract: This study investigated the effectiveness of Ca/Al-Cl LDH for the treatment of stabilized landfill leachate. Experiments were performed including different dosage of Ca/Al-Cl LDH and comparison with different reagents, such as CaCl2 and AlCl3. As a result, Ca/Al-Cl LDH efficiently removed organic matters in stabilized landfill leachate with the maximum removal (59.41% COD, 62.06% DOC and 70.56% UV254) at the dose of 30g/L. According to UV254 and EEM, it is remarkable that the formation of Ca/Al-LDH has a greater beneficial to organic removal than other reagents, especially for fulvic acid-like and humic acid-like compounds. Moreover, the removal of fulvic acid-like compounds was much better than humic acid-like compounds. The previous compounds had more carboxylic groups, thus had a better removal selectivity.
