Up to now, there are several remediation techniques such as ex-situ(excavation) or in-situ(on-site) soil washing/leaching/ flushing with chemical agents, chemical immobilization/stabilization method to reduce the solubility of heavy metals by adding some non-toxic materials into the soils, electrokinetics(electromigration), covering the original polluted soil surface with clean soils, dilution method (mixing polluted soils with surface and subsurface clean soils to reduce the concentration of heavy metals) and phytoremediation by plants such as woody trees[7,8,9].Considering the removal efficiency of pollutants and recycling,soil washing is particularly frequently used in soil remediation.Which is worked by applying water or aqueous washing solution to the soil to enhance contaminant solubility.
Materials and methods 2.1 Soil characteristics A soil sample, taken at depth from 0 to 20 cm in the Ecological Experimental Station, Shenyang, Liaoning Province of China.
Rocks and other large materials not passing throughthe sieve were removed. 2.2 Contamination Procedure After analyzing to determine its chemical and physical characteristics, the samples were then placed in plastic containers prior to artificial contamination.

The method of phenomenon does not like positive philosophy using natural science analytical method.
However people choice resident place and build city from natural environment, to the contrary natural environment provide material condition for city, moreover they have inner link between structure and property of environment with atmosphere and feature of city.

Introduction With the progress of science and technology, the traditional oil purification is no longer satisfied with the demands of hydraulic oil purification.
When the inlet pressure is small, the oil from preliminary purification can make a good contact with hydrophilic material in the RPB to get better separation efficiency.
