Soil Pollution Physicochemical Remediation Experiment
Soil remediation is a technical measure to restore the normal function of contaminated soil.
Experiment 1: Treatment of soil pollutants by electrothermal remediation
Electrothermal restoration is a technology that uses high-frequency voltage to generate electromagnetic wave heating to separate some volatile heavy metals from the soil, so as to achieve the purpose of restoration. The waveform required for this experiment is not a normal AC waveform, which is difficult to achieve with ordinary AC power. ITECH IT7600 high-performance AC power supply has built-in arbitrary waveform generator, which can simulate harmonics and various arbitrary waveform outputs, and has AC measurement and analysis functions. With the free IT9000-PV7600 software, you can easily import and export waveform data.
Recommended Products
- IT7600 high performance AC power supply
Experiment 2: Electric remediation method to treat soil pollutants
Electrokinetic repair is to transport heavy metal ions (such as Pb, Cd, Cr, Zn, etc.) and inorganic ions in the soil to the electrode by means of electroosmosis and electromigration under the action of an electric field. They are then collected and processed centrally. The DC power supply connected in the experiment should meet the following requirements: it can be connected to multiple reactors, the output power is high, the output voltage range is 0-100V, the output current is 0-3A, the voltage regulation and current regulation output, programmable, etc.
Recommended Products
- IT-M3400 bidirectional DC power supply
Experiment of Electrolysis Treatment of Industrial Wastewater
The electrolytic treatment of industrial wastewater utilizes the electrochemical properties of metals. Metal ions can be separated from relatively high concentration solutions during electrolysis and then removed. This experiment requires a DC power supply with CC priority mode so that the output current has no overshoot.
