Application of Polysilicate Ferric Flocculant in Treatment of Tanning Wastewater

摘要：

A new type of inorganic polymer flocculant polysilicate ferric(PSF) was prepared by using pyrite slag as raw materials and used as flocculant in the treatment of tanning wastewater.The infrared spectrometry and X-ray diffraction had been adopted to characterize the product structure.The infrared spectrometry research indicates that Fe-O,Si-O-Fe and other groups exist in the PSF,which implies that chemical bonding reaction takes place between Fe and silicon in the PSF.X-ray diffraction analysis indicates that PSF is the amorphous polymer created upon mutual reaction between Fe3+ and PSi.The application experiment results show that the removal rate of S2-,SS,CODcr,Cr3+,and colority is 92.7％,90.5％,82.5％,80.2％ and 90.1％ respectively in the condition where temperature is normal,pH value is 7.5 and dosage of the coagulant is 80mg/L.The flocculation effects of PSF in the treatment of tanning wastewater are much better than those of PAC and PFS.
