摘　　要：过硫酸盐作为氧化剂,经过活化可产生SO_4^-·。SO_4^-·氧化电位很高,在理论上能够降解大多数有机物。相比碱性与中性环境来说,酸性环境更有利于有机物的降解;而且温度对过硫酸钠氧化降解有机物影响很大。过硫酸盐氧化技术在当今日益剧增的印染有机废水的排放中具有很好的发展前景。国内外关于该技术的研究取得一定的成果。但是该技术受到多方面的影响,在课题组积累了大量的关于过硫酸钠活化文献和实验数据的基础上,详述了目前有关过渡金属活化过硫酸钠降解有机废水概况,着重从过硫酸盐的活化条件,包括过硫酸盐的投加量、待处理有机废水的酸碱性、温度以及Fe^(2+)等过渡金属投加量等进行了概述。Persulfate that is a strong oxidizing agent can produce SO4^-· after activation. SO4^-· Because of its high oxidation potential,theoretically could be able to degrade most organics. Compared to basic and neutral environment,acidic environment is more conducive to the degradation of organic matter;and temperature has a great influence on the sodium persulfate oxidation degradation of organic matter. In today＇s increasingly sharp increase in emissions of organic dyeing wastewater,persulfate oxidation technology has good prospects for development. Domestic and international research has made some achievements in this regard research,however it has some deficiencies. The basic consulted a lot of literature about sodium persulfate activation and accumulated a large number of experimental data of sodium persulfate activation,covered the transition metal persulfate activated before degradation of organic wastewater.And focus on from persulfate activation conditions,including dosage of persulfate,p H of pending organic wastewater,temperature,Fe2 ＋and other transition metal dosage.
