CaO2氧化/絮凝协同作用对印染废水的预处理实验
Synergistic Effect of CaO2/Flocculation on Textile Wastewater Pretreatment
摘要
Abstract
CaO2 is a reactive oxygen species which can effectively degrade the hardly-degraded organic pollutants, and flocculation of organic matter in industrial wastewater can carry out the electric neutralization of adsorption bridging. This study uses strengthening oxidation to explore pretreatment of textile wastewater by synergistic effect of CaO2/Flocculation. The results show that when the initial COD is 2 200 mg·L-1, the pH=6.5, the reaction time is 40 minutes and the dosage of calcium peroxide is 20 g·L-1 at 20℃, the removal rate of COD is 71%. After the re⁃action, adding PAC(0.7 g·L-1) and stirring for 3 minutes, the COD removal efficiency is 77%; After adding PAC (0.7 g·L-1) and PAM (8 mg·L-1), stirring for 3 minutes and then keeping 30 minutes, the efficiency of the floccula⁃tion achieves the best and the COD removal rate can reach 81%. Finally, it analyzes the influence mechanism of experimental factors.关键词
