摘要
本文采用共沉淀法制备纳米Fe3O4,将其和混凝剂PAC协同处理工业含油废水。试验结果表明:纳米Fe3O4对PAC处理含油废水的效果有着明显的增强作用;当废水温度为35℃,加入PAC为3.0 g/L,纳米Fe3O4为2.5 g/L、pH=8.0、反应时间为25 min时,CODcr去除率可达86.25%。
In this paper,nano Fe3O4 was prepared by coprecipitation method,and it was combined with coagulant PAC to treat industrial oily wastewater.The results show that nano-Fe3O4 can enhance the effect of PAC on the treatment of oily wastewater.When the temperature of wastewater is 35℃,adding PAC is 3.0 g/L,nano-Fe3O4 is 2.5 g/L,pH=8.0,and reaction time is 25 min,the CODcr removal rate can reach 86.25%.
