Study on Treatment of Wastewater Containing Chromium by Activated Carbon

Yin Chao

Abstract

Activated carbon has excellent absorption and reduction properties,and it has been widely used in wastewater treatment industry.Activated carbon amount of adsorption time,pH,temperature and other factors on the removal of chromium-containing wastewater were investigated in static test method.Research shows that if the dosing quantity is 0.6g/mL,pH value of 4,reaction time of 150min,the temperature 20℃,the treatment effect is best with discoloring rate close to 97%.Under favorable conditions,activated carbon can better remove Chromium in the wastewater.
