This paper utilizes minerals to resolve the problem of the obvious reduction of the efficiency of ozonization, which is caused by the high acidification of the dye wastewater during ozonization. First, high specific area mordenites modified with copper oxide dipping were used as adsorbent to improve the efficiency of ozonization. Second, natural alkaline mineral brucites were employed to counteract the high acidification. The results of the experiments show that two schemes of Cu_mordenite combined with brucite added to dye wastewater, with mass ratios between Cu-mordenite and brucite being 2∶1 and 1∶1 respectively, could increase pH value of the wastewater and improve the efficiency of ozonization. The value of COD decreasing rate of the dye wastewater with mCu-mordedite/mbrucitebeing 1∶1 is enhanced by almost 30 percent compared with that of the organic water with ozone only. In the end, the authors deduce three possible mechanisms for minerals in organic wastewater ozonization processes. They are adsorption of Cu-mordenites, alkali catalysis related to brucite decomposition and complex reaction between Mg2+ and organic acids.
