【摘要】 针对磷酸酯阻燃剂生产废水中COD质量浓度高,含有微生物难降解的成分,是一种难处理的有机废水的现实,利用Fenton氧化工艺对磷酸酯阻燃剂生产废水进行预处理,测定水中COD质量浓度的变化情况,以评价Fenton氧化工艺的处理效果,并考察Fe SO4·7H2O投加量、H2O2投加量及不同酸调节p H值对处理效果的影响。结果表明,最佳工艺条件为:Fe SO4·7H2O加入量为5 g/L,H2O2加入量为5.55 g/L;用硫酸调整p H值优于用盐酸调整p H值。更多还原

【Abstract】 Phosphoric ester flame-retardant wastewater is a kind of organic wastewater that is hard to treat because of its high concentration of COD with refractory biodegradable components. Based on these characteristics,the Fenton oxidation technique was used in this study for the treatment of phosphoric ester flame-retardant wastewater.The treatment effect was evaluated through detection of the change of COD concentration. The effects of dosages of Fe SO4·7H2O and H2O2 as well as p H adjustment with different acids in the treatment were investigated. The results show that the optimal conditions for the technique are as follows: dosages of Fe SO4·7H2O and H2O2 of 5g /L and 5. 55 g / L,respectively. In addition,sulfuric acid is superior to hydrochloric acid in p H adjustment.更多还原
