摘要：

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%,处理后废水可达到排放标准

Abstract:

When the wastewater from the production process of ?-naphthalene sulphonic sodium was treated with H₂O₂-Fe²⁺ oxidation ( H₂O₂/COD = 2.0g/g)，[ Fe²⁺]=4.0g/L，T=60min) after a coagulation-flocculation using FeCl₃ 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.
