    • A water treatment method by catalyzing ozone with a persulfate comprises the following steps: introducing the ozone into an ozone contact reactor filled with water to be treated; at the same time putting the persulfate into the reactor, wherein a stirring state is kept in the water treatment process. The method solves the problems of difficulty in the ionization of hydrogen peroxide, low capability in inducing the decomposition of the ozone, high hydrogen peroxide residues and inconvenience of hydrogen peroxide transportation and storage existing in the conventional water treatment method for catalyzing the ozone by using the hydrogen peroxide. Hydroxyl radicals and sulfate free radicals with strong oxidizing properties, which are generated by catalyzing ozone with the persulfate, are oxidized to remove pollution, so that the method has the advantages of high catalytic capability, high oxidative degradation efficiency, wide pH application range, a small amount of catalyst residues, convenience of operation and the like, and can be applied in mass production.
    • 通过用过硫酸盐催化臭氧的水处理方法包括以下步骤:将臭氧引入填充有待处理水的臭氧接触反应器中; 同时将过硫酸盐放入反应器中,其中在水处理过程中保持搅拌状态。 该方法解决了常规水处理方法中存在的过氧化氢离子化难以引起臭氧分解能力低,过氧化氢残留量高,过氧化氢运输和储存不便等问题。 过氧化氢。 通过催化臭氧与过硫酸盐生成的具有强氧化性质的羟基和硫酸根自由基被氧化以除去污染物,因此该方法具有催化能力高,氧化降解效率高,pH适用范围广, 催化剂残渣少,操作方便等优点,可以批量生产。
