A large\|scale testing landfill((3000×4)m 3)was filled with 10800 tons of refuse.The Ammonia\|N concentration of leachate was analysed every one to two weeks lasting for 3.5 years.A mathematical model was established to simulate the relationship of the Ammonia\|N value and time.It was found that Ammonia\|N Value would be reduced to 25mg/L after 21 years.The result indicated that it. If the current landfilling design and operating processes were modified,from discharging leachate promptly to discharging leachate after some time,so as to make Ammonia\|N concentration decrease naturally to some level,the manpower and material could be economized greatly and the operating processes could be simplified.
