hypoxia

Research on the treatment scaling at low temperature in circulating cooling water systems during the process of oxygen preparation;

制氧过程循环冷却水系统中低温结垢的研究

The alternation of anaerobic process and aerobic process were realized by periodical aeration of air and nitrogen.

结果表明,厌氧过程可以显著地增强生物除磷效果,与普通好氧过程相比,在进水总磷质量浓度为10mg/L时,磷的去除率可以提高30%,而COD的去除基本不受影响;适当延长厌氧处理时间和适当增大厌氧过程曝气速率可以改善厌氧环境及活性污泥性能,提高磷的去除率。
