摘要
为了经济、高效地处理水体中的氮、磷含量,通过粉煤灰漂珠经700℃焙烧,硫酸改性活化处理后,其孔隙率及比表面积增大,物理及化学吸附能力增强。结果表明,废水中投入3%的改性漂珠,废水的p H在8时,在40℃时吸附40min,可达到很好的除磷效果,除磷率达到98.31%。
In order to economically and efficiently decrease nitrogen and phosphorus content in domestic sewage,the porosity and specific surface area of fly ash cenospheres has increased through 700℃ calcining and H2 SO4-modifier activating treatment,which results in high physical and chemical adsorption. The results show that excellent removal ability of phosphorus would be obtained when the modified cenosphere dosage of 3% was put in domestic sewage,and adsorbed for 40 minutes at the temperature of 40℃ with the PH value being 8,that is,the rate of phosphorus removal reached 98. 31%.
