| titleOfInvention | A kind of electronation assisted electrochemical method removes chromic method in water |
| abstract | The invention provides a kind of electronation assisted electrochemical method and remove chromic method in water, described method comprise the steps: to pH value be 2～4 former water in add reducing agent and carry out chemical reduction reaction, make part Cr (VI) be reduced to Cr 3+ , it is electrochemically reacted subsequently into the electrochemical reactor that electrode material is ferrum, makes remaining Cr (VI) be reduced to Cr 3+ , the pH value of water raises simultaneously, Cr 3+ It is converted into Cr (OH) 3 , then by solid-liquid separation unit and sand filtration unit, it is achieved chromic removal in water.The technique of the present invention includes that chemical reduction method and electrochemical process remove chromium unit, then water outlet can reach wastewater discharge standard after solid-liquid separation.Present invention process system footprint is few, easily realizes equipment and Automated condtrol, and operating cost is cheap, is especially suitable for the online treatment of middle and small scale chromate waste water. |
