摘要
利用经不同温度以及相同浓度、不同改性物质改性后的沸石对废水中COD的去除率测定,结果表明酸、碱、盐改性的沸石对废水中有机物的去除率不同。改性浓度为0.5 mol/L时,NaCl改性沸石去除率最高。在工业生产中,采用NaCl改性沸石处理废水是一种较理想的选择。
With different temperature and same concentration,zeolite was modifed with different moddified substances,the detect of removal of COD with the modified zeolite was studied.The result showed that different elimination rates of organic matter in waste water were got with zeolites modified by acid,alkali and salt.When the modified concentration was 0.5 mol/L,the NaCl had the highest removal.In industry production,adopt NaCl modified zeolite to deal with waste water was a better way.
