一、药剂氧化 I. drug oxidation 废水中的有毒有害物质为还原性物质，向其中投加氧化助剂，将有毒有害物质氧化成无毒或毒性较小的新物质，此种方法称为药剂氧化法。在废水处理中用的最多的药剂氧化法是氯氧化法，即投加的药剂为含氯氧化物如液氯、漂白粉等，其基本原理都是利用产生的次氯酸根的强氧化作用。 Toxic and harmful substances in waste water reducing agents, to adding the oxide additives, toxic and harmful substances oxidation into non-toxic or toxic smaller new substances, this method is called reagent oxidation method. In wastewater treatment using the most reagent oxidation is chlorine oxidation, the additive agents for chlorine oxide such as liquid chlorine, bleaching powder, its basic principle is used to produce hypochlorous acid root strong oxidation. 二、臭氧氧化 Ozone oxidation 臭氧氧化法是利用臭氧的强氧化能力，使污水（或废水）中的污染物氧化分解成低毒或无毒的化合物，使水质得到净化。它不仅可降低水中的BOD、COD，而且还可起脱色、除臭、除味、杀菌、杀藻等功能，因而，该处理方法愈来愈受到人们重视。 Ozonation is a strong oxidizing capacity of ozone to decompose pollutants from sewage (or wastewater) into low-toxic or nontoxic compounds to purify water. It can not only reduce the BOD and COD in the water, but also can get rid of color, deodorization, deodorization, sterilization, killing algae and other functions. Therefore, the treatment method is getting more and more attention.
