| Abstract: | The structure and properties of the acid brilliant scarlet GR were analyzed. By the filtrating experiments of all kinds of coagulants, FeSO 4-MgSO 4-Ca(OH) 2-PAM were blended. The operational conditions were also optimized by experiments. The result showed that the COD removal ratio reached 85.3% and the most discoloration ratio reached 97.4% treating acid brilliant scarlet GR wastewater, COD of which was 288.3 mg/L and color of which was 25 000 times. When the discoloration ratio reached 90%, the cost of treating one ton of wastewater is$1.12 yuan. |
