Continuous and universal in-situ remediation appliance of soil combines taking soil, transmission and restoration of soil, which can achieve the in-situ remediation continuously and avoid the drawback of massive labor power and material resources using domestic soil ex-situ remediation device. The appliance supports many kinds of soil remediation technology, realizing the function of universal technology. And as for the area with serious pollution, various technology combinations can be selected to extend its function. The motion of specific remediation device in the appliance utilizes the single-chip controlling technology, controlling the remediation time interval of different technology. The program selection with various remediation technologies can be finished with buttons. Single-chip controlling system responds quickly, runs stably and precisely controls the remediation device.

Surface Observation

Biodegradable magnesium alloys are promising materials for application in medicine. The corrosion rate and type of corrosion are among the most important properties for this kind of materials. The fine-grained biodegradable alloys AZ31 (hot-rolled) and ZK60 (extruded) were studied in the present work with the use of in situ methods including the hydrogen evolution corrosion rate measurement and real-time surface observation as well as ex situ methods such as the weight loss assessment and the post-mortem examination by confocal laser scanning microscopy. The experimental methods included immersion test in SBF (0.9% NaCl aqueous solution) during 120 h with 37 °C with recirculating corrosion media. The hydrogen evolution was measured with a burette with a constant time interval of 1 hour. The real-time surface observation was carried out with a high-resolution camera. The measurement of pH level was done twice a day. Corrosion rate curves, 3D morphology of corroded morphology and video recordings showing evolution of corrosion damage have been obtained. As a result, ZK60 was found to be less corrosion-resistant and addicted to pitting corrosion, whereas AZ31 showed pronounced susceptibility to filiform corrosion.

Initial Concentration

Electrokinetic remediation is in-situ remediation technique. Potassium dichromate was chosen as the pollutant and its initial concentration was 500mg·kg-1 in Kaolin soil. This experiment, we are to study the feasibility ,the factors which influence the whole course, including applied voltage, treatment time, soil moisture, OH- produced at the cathode and its control. It indicate that, there is separating out oxygen at anode, hydry at cathode. Cr2O72-and CrO42- absorb electron to change to Cr3+, and unite to Cr (OH)3. The experiment results show OH- produced at the cathode has crucial effects on the removal efficiency of chromium; secondly the applied voltage and treatment time have important influence on the efficiency, and the soil moisture affects the efficiency in some degree.
