摘　　要：向倒置A2/O中试系统中投加2,4,5-三氯苯酚(TCP),研究TCP对污泥的减量效果及进入处理系统后对系统出水水质长期影响。研究结果表明:与参照组相比,加药组投加TCP 2 mg/L时,污泥减量达62.5%,出水TN比参照组平均高0.8 mg/L,137 d后出水TP超过0.5 mg/L。TCP对污泥的减量效果好,需要加除磷药剂进行辅助除磷。The 2,4,5 trichlorophenol（TCP） was added in reversed A2/O system and long-term effects of uncoupler addition on effluent and sludge reduction in activated sludge system were studied.The results showed that compared with the reference group,when the TCP addition concentration was 2 mg/L,the sludge was reduced by 62.5%.TN concentration of the effluent was 0.8mg/L higher than the reference group.After 137 d,effluent TP concentration was higher than 0.5mg/L.Addition of TCP was effective in sludge reduction,and the addition of phosphorus removal agents will be helpful.
