Research on Migration and Transformation of Leaches from Solid Wastes in Underground Medium
The characteristics of leaches composition of all pollutants was studied by means of leaching experiment of soil column in this paper, and the variation law of leaches and polluting mechanism in underground environment were analyzed too. The experimental results indicated that the COD of leaches changed mainly in 2 stages, i.e. the stages of rising of density to maximum in the beginning and decreasing in the end. The purification ability of peripheral medium to COD was relatively obvious, and the removal rate was 63.5% in column. The other pollution factors such as SO4 2- etc. varied in regularities too, and the surrounding soil medium had the abilities of absorption and biodegradation to the most ions in the infiltration fluid.
