摘要
研究了用Fendon试剂预处理含难降解有机物的草甘膦废水,考察了反应pH值、H2O2/Fe^2＋投加比例、Fendon试剂投加量和反应温度对总磷去除率、COD去除率的影响。结果表明,在pH=3-4、H2O2/Fe^2＋投加摩尔比为4∶1、H2O2投加量为8 g.L^-1,反应温度为90℃,反应时间为2 h的条件下,总磷去除率为95.7%、CODCr去除率为62.9%。由此可见,Fendon试剂能显著降低草甘膦废水中的总磷、CODCr值。
The pretreatrnent of glyphosate wastewater contained refractory organic pollutants was studied. The effect of pH, dosing percentage of H2O2/Fe^2 ＋ , Fendon dosage and temperature on the removal rate of TP and COD, were investigated. The result showed that the removal rate of TP and COD were 95.7% and 62.9% respectively under the circumstances of pH 3-- 4, molar ratio of H2O2/Fe^2 ＋ 4： 1, H2O2 dosage 8 g·^- l, temperature 90 ℃ in 2 h.
