The filtration basin can make the water clarify mainly depending on the filtration materials, which we commonly used, including quartz sand and anthracite grain.
Then the water arrives in the reaction basin to grow gradually into the flocculent deposit material (flocculating constituent or vitriol flower).

To apply PSi as a high surface area material for integrated sensors[13] or photo-electronic devices[14], it is necessary to form a transparent conductive layer which should not introduce a lot of non-radiative recombination centers[15].

The Analysis of Resources Environmental Effects of Rural Industrialized Areas Based on Ecological Footprint Chen Chen1, a, Wang Yuhua1, b, *, Niu Lei1, c 1College of Water Resources ＆ Civil Engineering，China Agricultural University，Beijing 100083, China a1260282729@qq.com, bwangyuhua@cau.edu.cn, c1185560526@qq.com Key words: ecological footprint; rural industrialized area; resources environmental effects; evaluation system Abstract: The rapid growth of rural industry has resulted in increased financial well-being, with improvement of farmers’ salaries and development of urbanization.
Hypothesis Type and amount of material resources consumption during the production and the degree of environmental pollution will be different due to the different of rural industrial structure types.
Each consumer can be traced back to the raw material for production of consumer goods and the energy needed for the ecological productive land area in theory.
Conclusion (1) Type and amount of material resources consumption during the production and the degree of environmental pollution will be different due to the different of rural industrial structure types, spatial distribution and technical means.

Rhizobium strains with general ability of P-solubilization that have good performance on plant growth promotion may provide good source material for engineering new strains with increased capacity for P solubilization as demonstrated by Rodriguez et al [40].
These are the key diagnostic tests used to distinguish Rhizobium species from other P-solubilizing bacteria.

Studies have shown that, TMD system has a good effect for reducing vibration caused by dynamic load with long period or narrow band, and the application prospect is very broad in civil engineering[3].
It is calculated according to the three-dimensional spatial structure and the materials properties come from codes in China.
Modal parameter of vertical acceleration time-history data of boarding bridge collected by vibration pickup are identified by Jiangsu Anzheng Software Engineering Co.
Considering that the actual connection of model often cannot achieve the ideal state which is assumed in the theoretical calculation, and decorative materials on both sides of the boarding bridge have not been installed in place, the measured value of boarding bridge tend to rigid is reasonable.
