摘　　要：针对焦化废水为含酚、氰废水的特性 ,从焦化厂处理焦化废水的活性污泥和油泥中分离出能降解酚的细菌7株 ,降解氰的细菌 8株 ,并对其降解能力进行了测定 ,结果表明 ,当酚浓度为 15 0 mg/ L经 6 h处理后 ,0 5 12菌株对酚的去除率达 96 .84% ;当 CN- 浓度为 2 5 mg/ L经 8h处理后 ,0 5 0 1菌株对 CN- 的去除率达 99.96 %。To the character of containing phenol and cyanide in the coke wastewater,the 7 strains of degrading-phenol and the 8 strains of degrading-cyanide were isolated from activated sludge of the coke wastewater treatment and oil mire in a coke-oven plant.On the basis of these strains,the experiments of degradation rate have been conducted,the results showed that strain 0512 for rate of degrading-phenol was 96.84% from 150mg/L to 4.74mg/L under 6 hours and strain 0501 for rate of degrading-cyanide was 99.96% from 25mg/L to 0.01mg/L under 8 hours.
