摘要
An apparatus for treating and recycling tannery wastewater based on nano catalytic electrolysis technology and membrane technology comprises a coarse grid filter (1), a regulating tank (2), a hydraulic screen (3), a nano catalytic electrolyzer (4), a reaction tank (5), sedimentation tank (6), an air floatation device (7), a biochemical tank (8), a secondary sedimentation tank (9), a secondary nano catalytic electrolyzer (10), a filter (11), and a membrane system (12). A method for treating and recycling tannery wastewater based on nano catalytic electrolysis technology and membrane technology is also provided. The steps of the method comprise nano catalytic electrolysis; flocculation; biochemical treatment; secondary catalytic electrolysis; filtration; and membrane filtration. The method has the advantages of high CODCr removal rate, low consumption of chemical agents, low production of sludge, thorough treatment, and high water recycling rate.
