H_2O_2-Fe^(2+)法处理β-萘磺酸钠生产废水的研究

APPLICATION OF FERROUS HYDROGEN PEROXIDE PROCESS TO THE TREATMENT OF WASTEWATER FROM THE PRODUCTION PROCESS OF β NAPHTHALENE SULPHONIC SODIUM

先用ＦｅＣｌ３进行混凝处理β－萘磺酸钠废水，后用Ｈ２Ｏ２—Ｆｅ２＋法氧化，在适宜的条件下，废水的ＣＯＤ和色度去除率分别可达９９．６％和９５．３％。

When the wastewater from the production process of β naphthalene sulphonic sodium was treated with H 2O 2 Fe 2+ oxidation (H 2O 2/COD=2.0g/g),[Fe 2+ ]=4.0g/L,t=60min) after a coagulation-flocculation using FeCl 3 at a dosage of 4g/L, the overall COD and colour removals were 99.6% and 95.3%. The indexes of the effluent could meet the national discharge standard.
