摘要
CMC废水属于高盐分高有机物废水,废水COD为50 000～80 000 mg/L,含盐量为13％左右,不适合直接生化处理.本文采用CMC废水和循环冷却水按一定比例混合后一起处理,混合后的废水采用UASB＋接触氧化法的处理工艺处理.工程运行表明：稀释后的CMC废水中的盐分稳定在1.4％以内,该处理工艺能够确保出水达到《污水综合排放标准》（GB8978-1996）中三级排放标准.
CMC wastewater belongs to high salinity 000 --80 000mg/L, the salt content is about 13 organic wastewater, wastewater COD is 50 %, not suitable for direct biochemical treatment. This paper uses CMC wastewater and circulating cooling water proportionally mixed together, treatment process using the UASB and contact oxidation process of the mixed wastewater. The practical operation shows that： CMC wastewater diluted salt in the stable within 1.4 %, the treatment process can ensure the effluent can meet the ＂integrated wastewater discharge standard＂ （GB8978-1996） in the three level of emission standard_
