| Abstract: | The direct electrolytic sludge reactor is used to remove heavy metals from the sewage sludge at 20v stable voltage.A comparative test is operated in two reactors with pipette solution of distilled water and the mixture of distilled water and electrolytes.The pH,voltage drop and heavy metal concentration of different sludge treatment region in reactors are monitored.The change of sludge property and the removal rate of the heavy metal are studied for different sludge treatment region during the electronic removal process.The effective region for removing the heavy metals with high concentration has been found. |
