| Abstract: | Formed fly ash was investigated through orthogonal experiment,and the influence factors of reactive time,pH value of wastewater and dosage of fly ash were studied.The results show that the formed fly ash gets the best absorption efficiency when the raw materials’ ratio is 80:10:10,the sintering temperature is 600℃,and the holding time is 90 minutes with a forming mass of 1g.For treating 100mL ammonia-nitrogen water of 30 mg·L-1,the optimum adsorption conditions are that the reactive time is 90min,the appropriate pH value is about 9,and the dosage of formed fly ash is 10g.The removal efficiency of ammonia-nitrogen is up to 40% under the optimum conditions. |
