| Abstract: | Utilize anionic polymers and cationic polymers combine with sodium sulfide(Na2S) and ferrous sulfate(FeSO4) to deal with hexavalent chromium containing wastewater.Na2S and FeSO4 are selected as reductant while gelatin and PAM are used for sedimentation.As to the data analysis,orthogonal experiments are used to design the whole research.Optimal treatment conditions for wastewater containing hexavalent chromium are determined through this process.The Cr6+ removal rate maintained 98.6% and the concentration wa... |
