Based on the simulated experiments, this paper discusses the mechanism of stabilization and the influence factors of the anaerobic-semi-aerobic landfill;confirms the evaluation index system and evaluation standard based on the comparison with the semi-aerobic method;and attempts to forecast the characteristic index of the COD of the anaerobic-semi-aerobic landfill by Chebyshev orthogonal self adapting method, then judges stabilization degree of this type landfill.The results of laboratory simulated tests in...
