Abstract:
Two experimental equipments of semi-aerobic landfill and anaerobic landfill were constructed. The total nitrogen concentrations of leachate (Recorded as CTN) that located at the bottom of equipments were determined periodically (1 or 2 times per week), the variation laws of CTN that located at the bottom of two landfill equipments with time were researched, and the reasons for the differences were also analyzed; During the period that the degradation of the landfill waste came into a relatively stable stage, the leachate that located at each sampling points of upper, middle and lower horizontal sections of the landfill equipments was collected periodically, and the CTN was determined, the CTN data of each point of upper, middle and lower layers were processed by using Surfer software respectively, and the spacial variation characteristics and differences of two landfill equipments were also discussed. The results indicated that the CTN of each point of the semi-aerobic landfill treatment were significantly lower than the corresponding anaerobic landfill treatment, the semi-aerobic landfill treatment could achieve the effective removal of total nitrogen from the leachate, and could accelerate the process of degradation stabilization and balance of total nitrogen in leachate.
