异VC钠废水处理的应用研究

摘要

采用UASB-生物接触氧化池-Biofor（一段式生物过滤氧化反应器）工艺处理异VC钠食品添加剂废水，结果表明：经过该工艺深度处理出水COD在40 mg/L左右， SS在30 mg/L左右，色度大约20倍。出水水质达到《污水综合排放标准》（GB 8978-1996）的一级标准。%The UASB-biological contact oxidation pond-Biofor (a type of biological filter oxidation reactor) process has been used for treating food additive wastewater from sodium erythorbate production. The results show that after the process for advanced treatment COD is about 40 mg/L,SS about 30 mg/L,and chroma is around 20 times. The effluent water quality reaches the first grade standard of The National Wastewater Discharge Standards(GB 8978-1996).
