| titleOfInvention | Technique and device for extracting sulfuric acid (H2SO4) from acid mine water |
| abstract | The invention discloses a technique and device for extracting sulfuric acid (H2SO4) from acid mine water. The technique is characterized by comprising the following steps of: removing suspended and colloidal materials from raw acid mine water through a coagulation and microfiltration process and then selectively adsorbing sulfate ions from the mine water by using an adsorbent (ZrO(OH)2, and soaking the adsorbent (ZrO(OH)2 (which is saturated in adsorption) by using a NaOH solution with a certain concentration so as to regenerate and recycle the adsorbent (ZrO(OH)2; electrolyzing the Na2SO4 solution generated after regeneration through a bipolar-membrane electrodialysis device, concentrating the NaOH solution generated in a cathode chamber to serve as a regenerative agent, and taking the H2SO4 solution generated in an anode chamber as an industrial product. The device for implementing the technique is composed of such units as a coagulation-microfiltration combined process device, a ZrO(OH) adsorption reactor, a ZrOSO4 regenerator, an adsorption separator, a regeneration separator, a concentrator and the bipolar-membrane electrodialysis device. |
