In summary, in order to analyze the transport of the leaching water of the opencast mine dumps and contaminated materials in the groundwater , it is necessary to model underground water and take precautions against mining impacts on the underground water.
In this sudy ,the solute transport model(MT3D) has been used in order to simulate the movement of waste water materials and leaching solution of the dump in the groundwater.

Introduction As a new promising biological sewage treatment technique, sequencing biofilm batch reactor (SBBR, also known as SBR or BABR) was widely studied and applied both at home and abroad[[]Lizhen Zhao and Yingqi Liao:.Journal of Jiangsu University of Science and Technology, Vol.22 (2001), p.59(In Chinese) ] in recent years.
Enrichment, reproduction, abscission of microbes in the biofilm was greatly influenced by the shape and texture of the material.
In this paper, two kinds of filler material of SBBR, one is luffa cylindrical sponge and the other is plastic sponge were compared for the sewage water treatment. 1 Materials and methods 1.1 Materials Luffa was from a farm in Yantai, Shandong Province.

These suggested that LCBER would be more suitable to glue biomass materials.
These processes are based on solvolysis of lignocellulosic materials.
The extreme high molecular weight portion of LCBER-30 was obtained using the corresponding LCB at 30 min as raw materials by GPC measurement.
The CB-based epoxy resin had good properties comparable to DGEBA epoxy resin, especially suited to glue biomass materials.

The results indicated that the pumice concrete could be developed as the green and multi-functional concrete materials in the future.
Pumice can be used in building materials, such as lightweight aggregate pumice concrete [4, 5], cement mixing materials [6], foam microcrystalline glass [7, 8] and pumice block [9-13], pumice plates and so on.
