Method and apparatus for electrochemical purification of contaminated liquids

摘要

A method comprises heating contaminated liquid, cooling electrolyte and subsequently passing the latter through soluble electrodes provided within an electrocoagulation chamber. Next, mixing the heated contaminated liquid is accomplished above the soluble electrodes with an ascending flow of cooled air containing products of dissolution of the soluble electrodes, followed by separating formed foam and sludge within a settling chamber. Apparatus having a settling chamber provided with an outlet pipe to discharge purified liquid. Inside the settling chamber, there is disposed an electrocoagulation chamber provided with an inlet pipe to feed contaminated liquid thereinto, and an inlet pipe to feed electrolyte. In the bottom portion of the electrocoagulation chamber, there is disposed a system of soluble electrodes. A heater communicates with the inlet pipe to feed a contaminated liquid, while a condenser communicates with the inlet pipe to feed electrolyte.
