摘要： PURPOSE: A method for purifying wastewater containing heavy metal-organic material complex using hexavalent iron is provided to efficiently purify the wastewater based on a simplified process using a solution containing hexavalent iron salt. CONSTITUTION: A method for purifying wastewater containing heavy metal-organic material complex includes the following: A solution containing hexavalent iron salt is prepared. The solution is mixed with wastewater containing the heavy metal-organic material complex. The complex is decomposed, and heavy metals are precipitated. The precipitated heavy metals are separated and eliminated. The pH value of the solution containing the hexavalent iron salt is maintained in a range between 9 and 10. The hexavalent iron salt is K_2FeO_4 or Na_2FeO_4. The heavy metal-organic material complex is selected from a group including Cu(II)-EDTA, Cu(II)-NTA, Cu(II)-EDDA, and Cu(II)-IDA.
摘要翻译：目的：提供一种使用六价铁净化含有重金属 - 有机物质复合物的废水的方法，以使用含六价铁盐的溶液简化工艺对废水进行有效净化。构成：含有重金属 - 有机物质复合废水的净化方法如下：制备含有六价铁盐的溶液。该溶液与含有重金属 - 有机物质复合物的废水混合。复合物被分解，重金属沉淀。沉淀的重金属被分离和消除。含有六价铁盐的溶液的pH值保持在9和10之间。六价铁盐是K 2 FeO 4或Na 2 FeO 4。重金属 - 有机物质络合物选自Cu（II）-EDTA，Cu（II）-NTA，Cu（II）-EDDA和Cu（II）-IDA。
