摘要
采用硫酸(H2SO4)和(或)十六烷基三甲基溴化铵(CTMAB)对膨胀珍珠岩进行改性,制备了不同改性膨胀珍珠岩(H2SO4-EP、CTMAB-EP、H2SO4+CTMAB-EP),并研究了不同改性膨胀珍岩对实际印染废水色度和COD的去除效果。试验结果表明:4mol/L H2SO4+5%CTMAB复合改性膨胀珍珠岩对实际印染废水的处理效果最好,且当该复合改性膨胀珍珠岩的投加量为27g/L、pH值为8、反应时间为4h时,COD去除率达到95.5%,色度去除率达到80%。
This paper prepares different modified expanded perlites （EPs） such as H2SO4-EP,CTMAB-EP and H2SO4/CTMAB-EP by using cetyl trimethyl ammonium bromide （CTMAB） and/or H2S（）4 to modify EPs in this e EPs as adsor that EPs mo xperiment, and then probes into the b bents for the study of the removal effi est modified conditions and uses the different modified cmncy dified with 4mol/LH2SO4 and 5~/00 CTMAB show ments. When H2SOa/CTMAB-EP treatment dosage is 27 COD removal rate of dyeing wastewater can reach 95.5 %
