Research on Nano-metal Clustersmedia Removing Hexavalent Chromium in Rainwater

摘要：

　　According to the problem of the northwest region excessive hexavalent chromium in the rainwater collection,this paper studies influence factors on Nano-metal clustersmedia removing hexavalent chromium through the orthogonal experiments and analyzes the different filter layer thickness,initial hexavalent chromium concentration,filter velocity and the water PH,and the influence of removal rate.The results show that: filter speed on Nano-metal clustersmedia removing hexavalent chromium effect plays a main role,and the effect of filter layer thickness plays a weak role.When the filter thickness is 300mm,the initial hexavalent chromium concentration is 0.2mg / L,water PH value is 7,and the filtration speed is 2m / h,the Nano-metal clustersmedia removal of hexavalent chromium is the best.
