基于过氧化氢的处理系统已被用于去除城市废水和工业加工废水中的无机和有机污染物。由于过氧化氢是一种强大的氧化剂，完全可与水混溶，因此它能有效地破坏各种污染物，是饮用水处理的理想化学品。由于对消毒副产物（DBPs）有更严格的规定，过氧化氢已越来越多地被用作城市饮用水预处理的氯替代品。与其他氧化剂相比，过氧化氢是一种有吸引力的替代物，原因有几个。 过氧化氢的分解产物是水和氧。此外，尽管过氧化氢系统的设计应确保产生的残余物最少，但如果存在残余物，可通过氯化有效去除过氧化氢。过氧化氢清除地下水和地表水饮用水供应中常见污染物的有效性示例。

Hydrogen peroxide based treatment systems have been used for several years for the removal of inorganic and organic contaminants in municipal wastewater and industrial process waters. Since hydrogen peroxide is a powerful oxidant and completely miscible in water, it is effective for destroying a broad spectrum of contaminants and an ideal chemical for potable water treatment. Due to stricter regulations on disinfection byproducts (DBPs), hydrogen peroxide has been used increasingly as a chlorine alternative for the pretreatment of municipal drinking water. Hydrogen peroxide is an attractive alternative to other oxidants for several reasons. Hydrogen peroxide has water and oxygen as decomposition products. In addition, although hydrogen peroxide systems should be designed to produce minimal residuals, if a residual is present, the hydrogen peroxide can be effectively removed by chlorination. Examples of hydrogen peroxide effectiveness for the removal of common contaminants found in groundwaters and surface water potable water supplies.
