| Abstract: | Tests were carried out for the treatment of chromium containing wastewater using a porous ferrous material made from concentrated breeze and ferric oxide.The result shows that when the particle size of the porous ferrous filter material is 1.45-2.00 mm,the pH value is 5-6 and the temperature is 20 ℃,the removal rate of Cr6+may reach 95%and that of total chromium may exceed 80%. |
