研究发现，CEH三段漂白废水中AOX大部分是出现在C段和E段，非木材浆C段漂白时约有2.5-4kg／odt的AOX形成，其中C段废水中溶出的AOX一般在2kg／t浆左右，E段为1-2kg／odt；H段废水中AOX含量较少，一般少于1kg／odt；非木材纸浆CEH漂白产生的AOX低于木材纸浆。

With the same final brightness about 84%ISO, O~*P pulp consumed less active chlorine and peroxide compared with the OP pulp; although O~*P pulp needed a higher beating energy,the tensile index,tear index and burst index of the pulp were better than those of OP pulp at the same ~oSR value.

当漂白浆的白度均为84%ISO左右时，与CK2 OP漂白浆相比，CK2 O~*P(O~*为表面活性剂S3强化的氧脱木素)漂白浆所消耗的漂白化学品的量更少，即氧脱木素段添加合适的表面活性剂能有效降低漂白化学品用量。

Oxidative bleaching by oxidation of its own to make a strong oxidation of colored substances were destroyed, so as to achieve the purpose of bleaching; food mainly used to restore the bleaching agent, mostly belonging to sulfurous acid and its salts, they are generated through the reduction of the role of sulfur dioxide can fruits and vegetables fade, it is widely used in food products such as bleaching and preservation.

氧化漂白是通过其本身强烈的氧化作用使着色物质被氧化破坏，从而达到漂白的目的；食品中主要使用还原漂白剂，大都属于亚硫酸及其盐类，它们通过产生的二氧化硫的还原作用可使果蔬褪色，因此广泛应用于食品的漂白与保藏等。
