The Removal of Deinking Wastewater Using Neutralization, Activated Carbon, and Hydrogen Peroxide Oxidation

Abstract:

Treatment of deinking wastewater with neutralization, activated carbon, and hydrogen peroxide oxidation is investigated. Discusses the various factors of the neutralization experiment and catalytic experiment on the influence of the experimental results. The results show that for the 20mL deinking wastewater, first neutralize it to pH=4 with dilute sulfuric acid, then the mass fraction of 0.8mLH₂O₂ (mass fraction of 30%) and 0.8g active carbon powder in oxidative 19min under conditions of pH=3 with an optimum addition of 0.8mg H₂O₂ (30%) as well as 0.8g active carbon powder, the CODcr can be reduced from 31000mg/L to 2300 mg/L, and the color unit can be reduced from 15000 to 0 after treatment ,its CODcr and color unit decrease significantly and the removal rates reach 90% and 100% respectively.
