On the basis of solute transport theory, the coal gangue eluviated in Xinqiu in Fuxin coal miming area was studied for the pollution of groundwater. The mechanism of coal gangue eluviated in the aquifer was analyzed. A coupled numerical model was developed with convection、sorption and dissolve、disintegration for simulating the leachate transport in groundwater. The model was discreted by using a Gelarkin finite-element method and a Picard iteration scheme, and the process of coal gangue leachate was presented, which predict the temporal and spatial distribution features of contaminant concentration. The result indicates that the contaminated plume is continually extended as time increases, and the vertical diffusion is more abvious.

以溶质运移理论为基础，针对阜新市新邱露天煤矿煤矸石淋滤液对地下水污染实际情况，分析了煤矸石渗滤液在含水层中运移的规律，在综合考虑对流扩散、吸附解吸、生物降解条件下建立了淋滤液在地下水中运移的耦合动力学数学模型，采用Galerkin有限元方法和Picard迭代法相结合对耦合模型进行了离散，模拟了淋溶液对地下水污染的动态过程，预测了污染浓度的时空分布特征，并结合实际观测数据进行对比。

However, the conversion rate of glycerol produced from the first stage using cornstarch to 1,3-propanediol from the second stage was only 26.5 % in 31h and the final concentration of 1,3-propanediol was 13.4 g/L. The productivity of 0.43 g/ of the second stage was much lower than that of a two-stage-fermentation from glucose （1.65g/ L） or of single fermentation from saponified glycerol, which is
