氧化处理:通过向水中加入氧化剂,如臭氧、高锰酸钾等,可以氧化分解水中的有机污染物和产生异味的物质。臭氧是一种强氧化剂,它可以与水中的异味化合物发生反应,将其分解为无味或气味较小的物质。例如,水中的硫化氢是一种具有臭鸡蛋气味的物质,臭氧可以将其氧化为硫酸盐,从而消除异味。同时,高锰酸钾也可以氧化水中的一些还原性异味物质。
Oxidation treatment: By adding oxidants such as ozone, potassium permanganate, etc. to water, organic pollutants and odorous substances in the water can be oxidized and decomposed. Ozone is a strong oxidant that can react with odorous compounds in water, breaking them down into odorless or less pungent substances. For example, hydrogen sulfide in water is a substance with a foul egg odor, which can be oxidized to sulfate by ozone to eliminate the odor. Meanwhile, potassium permanganate can also oxidize some reducing odor substances in water.
混凝沉淀:在水中加入混凝剂,如聚合氯化铝、硫酸亚铁等,这些混凝剂可以使水中的悬浮颗粒、胶体等杂质凝聚成较大的颗粒,然后通过沉淀或过滤的方法去除。一些产生异味的物质可能附着在这些悬浮颗粒上,当这些颗粒被去除后,异味也会随之减轻。例如,水中的藻类分泌物等有机杂质在混凝沉淀过程中被去除,减少了水的腥味。
Coagulation precipitation: Adding coagulants such as polyaluminum chloride, ferrous sulfate, etc. to water can condense suspended particles, colloids, and other impurities into larger particles, which can then be removed through precipitation or filtration methods. Some odor producing substances may adhere to these suspended particles, and when these particles are removed, the odor will also be reduced. For example, organic impurities such as algal secretions in water are removed during the coagulation and sedimentation process, reducing the fishy smell of the water.
