摘　　要：黏胶废水经生化处理后COD仍不能满足后续膜法处理的要求,为此选取煤质炭和再生椰壳炭进行吸附处理。结果表明,再生颗粒椰壳活性炭可将经混凝或砂滤后的黏胶生化废水(pH值为6.8~7.5,水温为27℃~33℃,COD<270 mg·L^(-1))COD降低至50 mg·L^(-1)以下,可以满足后续膜法处理制中水的要求。After biochemical treatment,the COD of viscose wastewater still can not meet the COD requirements of subsequent membrane treatment.Therefore,coal carbon and regenerated coconut shell carbon were selected for adsorption treatment.The results showed that regenerated coconut shell activated carbon can reduce COD of viscose wastewater after coagulation or sand filtration(pH 6.0~7.5,temperature 27~33℃,COD<270 mg·L^(-1))to less than 50 mg·L^(-1),which could meet the COD requirement of subsequent membrane treatment.
