经柠檬酸处理后，污泥中90%以上的重金属被去除；柠檬酸处理液中的重金属用离子交换法回收，考察了树脂种类、流速、操作方式等因素对离子交换、再生效果的影响；在适宜工艺条件下，重金属的交换率均为100%，而洗脱率均接近90%；柠檬酸及离子交换树脂循环使用，重金属也得到回收，降低了处理成本。

The concept and the classification of forecasting are addressed. Aiming at the disadvantages of the current forecasting models, such as requirement for more data and narrow application extent, an improved GM(1,1)-transfer function-noise model for forecasting is proposed. In the first stage, the GM(1,1) model improving the generation method of neighborhood system is adopted so as to fulfil the forecasting by only using a few of data.
