    • A two stages electrocatalytic method for oxidative-purification of wastewater from soluble substances, such as toxic chemical admixtures difficult of oxidation, including dye-stuffs, detergents, phenols, cyanides and the like, which stages inactivate the soluble substances present in the wastewater in a synergistic fashion and, therefore, are highly efficient, the method comprising the steps of (a) in a first stage, electrochemically treating the wastewater in the presence of chlorine ions, such that chlorine-containing oxidizing agents are formed and at least partially oxidize the soluble substances in the wastewater; and (b) in a second stage, catalytically treating the first stage treated wastewater in presence of a non-chlorine oxidizing agent and an added catalyst, such that remainings of the soluble substances are further oxidized, and such that the chlorine-containing oxidizing agents formed during the first stage are catalytically reduced; wherein, the first stage and the second stage act synergistically to purify the wastewater from the soluble substances.
    • 一种用于从可溶性物质氧化净化废水的两阶段电催化方法,例如难以氧化的有毒化学混合物,包括染料,洗涤剂,酚类,氰化物等,其阶段使废水中存在的可溶性物质失活 协同的方式,因此是高效的,该方法包括以下步骤:(a)在第一阶段,在氯离子存在下电化学处理废水,使得形成含氯氧化剂,并至少部分氧化 废水中的可溶性物质; 和(b)在第二阶段中,在非氯氧化剂和加入的催化剂的存在下催化处理第一阶段处理的废水,使得可溶物质的残留物被进一步氧化,并且使得含氯氧化剂 在第一阶段形成的催化还原; 其中,第一阶段和第二阶段协同地起作用以从可溶性物质净化废水。
