摘要
利用Fenton试剂和氧化镁联合处理化学实验室排水,探讨联合处理的最佳工艺条件。结果表明:在pH值为5时,加入15g/L过氧化氢和2g/L硫酸亚铁搅拌反应30min,废水的COD去除率达82.1%,经二级处理后排水中的COD去除率达96.4%;加入15g/L氧化镁后废水中的重金属离子去除率达到99.8%。
The Fenton reagent and MgO were used to treat the wastewater from a chemical laboratory,and the optimal technological conditions for wastewater treatment are discussed.The results show that the removal rate of COD was 82.1% when the pH value was 5,the dosage of H2O2 was 15 g/L,the dosage of FeSO4 was 2 g/L,and the reaction time was 30 minutes at ambient temperature;that the removal rate of COD was 96.4 % after secondary treatment;and that the removal rate of heavy metal ions was 99.8 % when 15 g/L of MgO was added to the wastewater.
