| titleOfInvention | Method and system for in-situ preparation of hydrogen sulfide for treating arsenic-containing wastewater |
| abstract | The invention discloses a method and a system for in-situ preparation of hydrogen sulfide for treating arsenic-containing wastewater, wherein the method comprises the steps of sulfur dioxide adsorption, flue gas circulation, heating and cooling operation and hydrogen sulfide collection; the method overcomes the industrial application defect of preparing the hydrogen sulfide gas by microwave heating, and the generated hydrogen sulfide can be directly used for treating arsenic-containing wastewater to remove arsenic, thereby realizing the industrial in-situ preparation of the hydrogen sulfide and the treatment of the arsenic-containing wastewater. The system comprises a first activated carbon fixed bed, a first condensing device, a second activated carbon fixed bed, a second condensing device and a leaching device; the invention relates to a system. The system has a simple structure, can replace and recycle the byproducts, can automatically carry out the treatment process, has the advantage of simple operation, and effectively reduces the labor cost. |
