| Abstract: |
| Based on the analysis of the properties of component and danger of copper smelting contaminated acid,this paper reviews the present situation and existing problems of the processing technologies in the domestic and overseas. The main processing technologies are the method of sulfidization, the method of lime-iorn salts ,the method of membrane ,the method of resin,the method of biology and the method of concentration of dilute sulphuric acid nowadays.But the traditional processing technologies of copper smelting contaminated acid can only make the emission reach a certain standard.They also produce other problems such as large amount of slag and secondary pollution ,high cost and so on during the process.In order to solve these problems ,the developing trend of processing technology of copper smelting contaminated acid is as follows:Firstly,reduce the hardness of water .Secondly, fluorine and chlorine also should be carried on the depth of processing.Moreover,heavy metals such as arsenic and dilute acid also can be recycled and reused .Finally, the secondary pollution should be reduced . |
