Embodiment Construction
[0043] Refer below figure 1 Describe in detail an embodiment of the preparation method of polyferric sulfate provided by the present invention; as shown in the figure, the preparation process of primary polyferric sulfate in this embodiment mainly includes the following steps:
[0044] In step 1, transport ferrous sulfate heptahydrate with a weight ratio of 40%-50% and titanium dioxide waste sulfuric acid with a weight ratio of 60%-50% to the mixing tank for material mixing, and deploy titanium H in white powder waste sulfuric acid 2 SO 4 The concentration range is 21%-23%, and the mixed reaction materials are obtained; during specific implementation, industrial sulfuric acid can be used to adjust the H in the titanium dioxide waste sulfuric acid. 2 SO 4 concentration.
[0045] In step 2, the reaction materials are sent into the reaction tower, and during the process of the reaction materials entering the reaction tower, the weight proportion is 0.2%-0.4%, the metal concen...
