Application of membrane mass transfer and separation technology in wastewater treatment

Application of membrane mass transfer and separation technology in wastewater treatment

(Summary description)The traditional chemical water treatment process has a large amount of slag and the risk of secondary pollution of slag. The key technology is the innovation of membrane technology in the comprehensive utilization of mine wastewater resources, the innovation of key technology of scale inhibition, the development and innovation of combined process, and the application effect is realized A 4000 m3 / D membrane treatment system has been set up for the industrial application in the field of copper acid pit water treatment, which is used to recover valuable metal copper from copper bearing acid mine wastewater. The annual recovery of copper metal is 12 million yuan, and the cost of reagent is saved by 6
