| 摘 要： | 为了探讨以粉煤灰做吸附剂降低废水中氨氮含量的规律,用粉煤灰对含氨氮为10~200 mg/L的模拟废水进行脱氨氮的试验。试验结果表明:粉煤灰是一种有效的吸附剂,在含氨氮为10~200 mg/L的模拟废水中,每50mL废水粉煤灰用量为5~10 g,粒径范围160目以上,pH值为4.5~6,振荡时间4 h以上,在上述条件下氨氮去除效率在50%以上。

| Abstract: | To reduce the ammonia-nitrogen in the wastewater,this paper studied the ability of coal ash to remove ammonia-nitrogen from wastewater.The results showed that coal ash is effective to adsorb ammonia-nitrogen.When concentration of ammonia-motrpgem was 10~200 mg/L,amount of coal ash used 5~10 g and particle size above 160 mesh,pH between 4.5 and 6,surge more than 4 hours,the efficiency of ammonia-nitrogen removal rate reached above 50%. |
