| titleOfInvention | Repairing method of hexavalent chromium polluted building garbage |
| abstract | The invention relates to the field of soil pollution remediation, and particularly provides a remediation method of hexavalent chromium polluted building garbage. The repairing method comprises the following steps: repairing construction waste with hexavalent chromium concentration of more than 500mg/kg by adopting a reinforced heap leaching method, wherein the reinforced heap leaching method comprises the following steps: firstly, stacking construction waste with the particle size of less than 20mm into a heap leaching pond, then adding a reducing agent, an organic fertilizer and/or glucose into a construction waste pile body to carry out reduction reaction, paving a biological coating on the outer side of the pile body, then collecting a construction waste sample to carry out detection, and if the concentration of hexavalent chromium does not reach the standard, sequentially carrying out reduction reaction and detection until the concentration of hexavalent chromium reaches the standard, and finally discharging liquid in the heap leaching pond; the reducing agent includes dilute sulfuric acid and ferrous sulfate solution. The method is suitable for repairing large-particle pollutants such as construction waste and the like, and has the advantages of simple and mature process, good hexavalent chromium reduction effect and low cost. |
