Dye wastewater cyclic utilization device and method based on electrolysis and lamination technologies

Abstract

The invention provides a dye wastewater cyclic utilization device and method based on electrolysis and lamination technologies, relating to a dye wastewater treatment and cyclic utilization method. The dye wastewater cyclic utilization device based on the electrolysis and lamination technologies provided by the invention is based on combination of a nano catalytic electrolysis technology, the lamination technology and a traditional dye wastewater treatment technology and has low cost and high efficiency, and the dye wastewater passes through a secondary sedimentation tank treated by biochemistry for carrying out wastewater regeneration recycle utilization. The device is provided with a nano catalytic electrolysis system, an immersed ultrafiltration membrane filtering separation system, anultrafiltration membrane washing system, a reverse osmosis membrane filtering separation system, a reverse osmosis filtering recovery cyclic system and a reverse osmosis membrane washing regenerationsystem. The method comprises the following steps: extracting the dye wastewater in a water supplying pump, and then feeding the extracted directly wastewater into a nano catalytic electrolysis machine; directly feeding nano catalytic electrolysis water into a depositing tank, and carrying out sedimentation; and then removing chlorine generated by nano catalytic electrolysis, solid impurities, planktons, germs and colloids in the wastewater by the immersed ultrafiltration membrane system, thus purified wastewater is obtained.
