摘　　要：通过对糠醛渣进行改性处理来吸附含磷废水中的磷,取得了良好的吸附效果。探讨了吸附时间、改性糠醛渣投加量、磷初始浓度、pH等因素对除磷效果的影响。结果表明,对于20 mg/L的含磷废水,在25℃、pH为2～12、投加量为1 g、反应时间为60 min时,改性糠醛渣对废水中磷的去除率为98.26%,净化后的出水可以达到国家污水排放一级标准。The phosphate in simulated phosphate-containing waste water was adsorbed by modified furfual residue;And good effect was achieved.Factors influencing the removal rate of phosphate such as contact time,dosage of moified furfual residue,pH,pellet size were investigated.It was found that the removal rate of phosphate could reach over 98.26% under the conditions of pH range 2～12,25 ℃,dosage of 1 g,phosphate initial concernation of 20 mg/L,and the adsorption time of 60 min.And the phosphate content in the purfied water could reach the level of national discharge standard.
