| 次氯酸钙氧化法能较好的去除简单氰化物，对低浓度的含氰废水处理效果良好。其最佳工艺条件为：次氯酸钙加药量为理论加药量的3.5倍、反应pH为10、反应时间为30min。在此条件下用次氯酸钙处理总氰化物浓度为8.15mg/L的含氰废水，处理后，废水总氰浓度为0.38mg/L，总氰化物去除率为95.34%。 |

Calcium hypochlorite oxidation can well remove the "simple" cyanide especially for the low concentration cyanogen-contained wastewater. The optimum process conditions will be:the adding quantity of calcium hypochlorite is 3.5 times than theoretical value,pH is 10,reaction time is 30min.The 8.15mg/L cyanogen-contained wastewater will be well treated under this condition,the total cyanogen-contained wastewater concentration is 0.38 mg/L and the removal rate will be 95.34% after treatment. Keywords: Calcium hypochlorite Reaction time Cyanide |
