  • 摘要: 以畜禽废水为处理对象,通过分别控制水力停留时间(HRT)、溶解氧(DO)、pH值、温度和碳氮比(C/N)等影响亚硝化的主要单因子,以使固定化活性污泥颗粒实现短程硝化反硝化反应,在连续流运行模式下进行废水脱氮实验,实验结果表明,单因子HRT为10 h,溶解氧为4 mg/L,pH值为8.5,温度为30℃,碳氮比为10时,对TN和COD的去除率分别为81.98%、93.79%;87.32%、98.35%;83.82%、93.93%;85%、97%;85.37%、97.28%,达到了理想的去除效果。
    Abstract: This study investigated the control of several major single factors influencing nitrosification, including hydraulic retention time (HRT), dissolved oxygen (DO), pH, temperature, carbon-nitrogen ratio (C/N), on denitification of livestock wastewater under a continuous flow operation mode, in order to achieve stable shortcut nitrification-denitrification by immobilized activated sludge particles. The results show that the removal rates for TN were 81.98%, 87.32%, 83.82%, 85%, and 85.37%, respectively, for a single factor (HRT) of 10 h, dissolved oxygen of 4 mg/L, pH value of 8.5, temperature of 30 ℃ and carbon-nitrogen ratio of 10. While those for COD were 93.79%, 98.35%,93.93%,97%, and 97.28%, respectively under the same conditions. The outcome of this study suggests that the removal efficiency of this technology is satisfactory.
