| titleOfInvention | Preparation method of titanium-containing composite ferric polysulfate flocculant |
| abstract | A method for preparing a titanium-containing composite ferric polysulfate flocculant relates to the field of preparation of ferric polysulfate, and comprises the following steps: firstly, preparing sol containing nano titanium dioxide. And adding sulfuric acid into the titanium dioxide sol to obtain the acidic nano titanium dioxide sol. And secondly, preparing the composite polymeric ferric sulfate flocculant. Dissolving ferrous sulfate heptahydrate by using an acidic solution containing nano titanium oxide. The composite polymeric ferric sulfate is prepared by adopting a chlorate oxidation method, a hydrogen peroxide oxidation method or a nitrite catalysis method. The prepared composite polymeric ferric sulfate contains nano titanium dioxide, has photocatalysis effect besides flocculation effect, and has excellent purification effect on micro-polluted, low-temperature and low-turbidity raw water with low COD. |
