摘　　要：焦化废水毒性大,有机物含量高,较难处理。引入生物制剂处理焦化废水,通过在序批式生物反应器上的对比试验,研究了生物制剂处理焦化废水的效果。结果表明:在温度为25℃左右,曝气16h,投加生物制剂后,COD、挥发酚、氰化物、氨氮去除率平均增加了9.5%、0.6%、3.3%、35.1%,且反应器耐有机物冲击负荷能力有所提高。It is difficult to had been done in batch reactor treat coke-making wastewater with high toxicity and organism. Contrastive experiments sequencing by microbial agents in order to investigate the treatment effect. The results show that under the temperature of about 25℃, aeration time 6 hours, the SBR reactor inoculating microbial agents have better disposal effect than the common SBR reactor. The efficiency of COD, phenol, cyanide and NH3-N removal averagely increases by 9.5%, 0.6%, 3.3% and 35.1% respectively. In addition, the ability of the reactor resisting changes of sludge loading is improved.
