摘要
通过研究硫酸亚铁预处理焦化污水对活性污泥影响的实验,提出硫酸亚铁预处理方法的适宜条件.指出在适宜情况下,硫酸亚铁预处理焦化污水具有良好的可生化性.
By experimental study on effects of coking sewage pretreated by ferrous sulphate on activited sludge process,suitable operating conditions were presented.The results of the experi- ments show that pretreated coking sewage had good biological oxidizability under the suitable amount of ferrous sulphate added,pH value and the amount of cyanide in the pretrcated sewage. It is important by this procss to raise biological clarification efficiency,ensure the quality of dis- charge sewage and make use of waste material effectively.
