| titleOfInvention | apparatus for retrieving Cr waste water using ion exchange resin |
| abstract | The present invention relates to a chromium wastewater treatment regeneration device using an anion exchange resin, and a filtration tank for storing chromium wastewater (1) and filtration connected to the reservoir (1) to receive wastewater from the reservoir by a supply pump (2). Tower 3, a cation tower 7 for ion exchange by receiving chromium waste water supplied from the filtration tower 3, an anion tower connected to the cation tower 7, and the ion towers described above. A cartridge filter 21 for filtering the wastewater discharged, a pure water storage tank 10 storing the treated pure water discharged through the cartridge filter 21 and re-input to the plating process, and an ion tower connected to the ion towers Sulfuric acid storage tank (13) and caustic soda storage tank (14) installed so that sulfuric acid and caustic soda can be supplied for regeneration of their performance, and the anion tower can be regenerated with caustic soda every 5-10 times before regeneration of hydrochloric acid. Enable anion tower and kite And is connected to the hydrochloric acid storage tank 15 is to be installed, each of the components, save the waste liquid coming from the element that is characterized in that it comprises a waste liquid reservoir 23 for the waste water treatment |
