摘　　要：通过研究2家制浆造纸企业的废水与污泥样品,探究了废水处理流程中,可吸附有机氯化物(AOX)去除途径与其在污泥中的微观赋存规律。研究表明,制浆造纸废水末端AOX浓度低于1.0 mg/L;AOX主要通过生化处理去除,剩余污泥是AOX迁移的重要介质。AOX主要赋存于污泥细胞相与胞外聚合物(EPS)中,污泥吸附量达到总AOX处理负荷的21.1%~24.8%。Wastewater and sludge samples were collected from two pulp and papermaking enterprises to explore the path of adsorbable organ⁃ic halides(AOX)removal during wastewater treatment process and its microscopic occurrence in sludge.The results showed that the termi⁃nal AOX concentration of pulp and paper wastewater was lower than 1.0 mg/L.AOX was mainly removed through biochemical treatment,and the residual sludge played an important role in AOX migration.Sludge adsorbed 21.1%~24.8%of total AOX from influent,and the ad⁃sorbed AOX concentrated in the sludge cell phase and extracellular polymeric substance(EPS).
