碩士 === 國立中央大學 === 環境工程研究所 === 82 === The leachate from solid waste has been a serious pollutant problem to human beings.In Taiwan,there are 87% of solid waste was treated by discarded.Because the climate of Taiwan is warm and rainy,there will be much leachate from solid waste.If the leachate was not treated properly,it will pollute the river and groundwaterand become secondary pollution. The leachate model can provide the pridiction of concentration,so we need to develop an effective model for the treatment of leachate. The model deduced here consider the following terms: (1) Solid degradable easily and degradable hard. (2) Lquid that mobile and stagnant. (3) Gas generated from the decomposition of organic substrate. And we have the following results: (1)The decomposition of organic substrate is the remarkable factor of leachate concentration. (2)The model consider mobile phase and stagnant phase can pro- vide more accuarcy of heightest concentration and the time of its appearance. (3)Hamming predictor-corrector method and finite element method have the same solution of model deduced here. (4)Density is the most obvious reason influence leachate con- centration.
