摘要：
For traditional mineral development issues such as excessive consumption of resources, deterioration of the ecological environment, proposed develops the vein mining industry on the basis of the artery mining industry, forms the positive cycle system, realizes the integrated development of vein mining industry and artery mining industry. The integrated development of artery mining industry and vein mining industry is an open complex system, the traditional scientific methods cannot solve complex system problems, and complexity science method must be used to resolve it. Through complexity analysis of dissipative structure, coordination effect , overall emergence and complex adaptive system (CAS) of artery mining industry and vein mining industry integrated development, proposed the methodology of research artery mining industry and vein mining industry integrated development is the meta-synthesis, has provided a path of sustainable development for the region mining industry.

摘要：
以城市污水处理厂污泥为原料,采用磷酸活化-微波热解法制备得到污泥活性炭,并将其用于吸附水溶液中的Cr(VI)。分别采用元素分析仪(Vario EL cube)、比表面积孔径分布测定仪(ASAP2020)、扫描电镜(SEM)和傅里叶红外光谱(FT-IR)等仪器对原污泥及污泥活性炭的表面组成和结构进行表征,探讨污泥活性炭的孔隙结构参数和表面化学性能。通过静态吸附实验,考察了溶液初始pH,接触时间,初始Cr(VI)浓度对污泥活性炭吸附Cr(VI)效果的影响,并探讨了污泥活性炭去除Cr(VI)的机理。实验结果表明,pH越低吸附效果越好,吸附平衡时间为100 h。不同温度下吸附过程均符合Langmuir等温吸附模型,30℃时最大吸附容量为27. 55 mg/g;吸附动力学过程符合准二级速率方程(R~2 >0.99);污泥活性炭对Cr(VI)的去除是一个吸附-还原耦合的过程。
