摘要
采用CaO/NaAlO2预处理-微电解-Fenton工艺对经物化-生化处理后的精制棉废水进行处理。当控制n(Ca^2+)∶n(Al^3+)比为4∶1,n(Ca^2+)∶n(Cl^-)为11∶1时,氯离子去除率达84.11%,COD去除率达81.25%,高于Fenton法、Fe/C微电解法、Fe/C微电解-Fenton联用的较优COD处理效果(42.5%、20.21%、65.625%),GC-MS分析表明,经CaO/NaAlO2-微电解-Fenton处理后废水中有机物大量减少,只有少量γ-谷甾醇残留。
The refined cotton wastewater after the physicochemical treatment is further treated by CaO/NaAlO2 pretreatment-microelectrolysis-Fenton process.When the ratio of n(Ca^2+)and n(Al^3+)is 4∶1 and the ratio of n(Ca^2+)and n(Cl^-)is 11∶1,the removal rates of chloride ion and COD are 84.11%and 81.25%,respectively.The COD removal rate is higher than that of Fenton method,Fe/C micro-electrolysis method,Fe/C microelectrolysis-Fenton combined with better COD treatment effect(42.5%,20.21%,65.625%).Through the GC-MS analysis,the organic matter in the wastewater was greatly reduced,and only a small amount ofγ-sitosterol remained after CaO/NaAlO2-microelectrolysis-Fenton treatment.
