Problems solved by technology
At present, polyaluminum chloride is mainly prepared by reacting aluminum ore powder, industrial recycled aluminum slag and industrial by-product hydrochloric acid. Due to the complex composition of aluminum ore powder, aluminum slag and industrial by-product hydrochloric acid in this preparation method, they all contain certain Heavy metals, organic matter and other impurities, resulting in polyaluminum chloride products usually contain some harmful impurities, which will cause harm to human health or the water environment after use
When the product quality requirements are high, some manufacturers of polyaluminum chloride prepare polyaluminum chloride by using aluminum hydroxide, an intermediate product of the smelter, and genuine hydrochloric acid. This method is expensive in raw materials and cannot be applied on a large scale, which is not conducive to promoting the industry progress and development

The invention relates to the technical field of purification, and discloses a purification device for polyaluminum chloride and a purification method thereof. The purification device comprises a column body, the interior of the column body is hollow, and an opening is formed in the top of the column body; an aluminum carbon bed is arranged in the column body, and a sand core baffle is fixedly mounted at the bottom in the column body. According to the purification device for polyaluminum chloride and the purification method of the purification device, aluminum skimmings and biochar serve as raw materials, an aluminum-carbon reduction battery is formed through aluminum carbon, Fe<2+> is formed on an anode, the Fe<2+> and many heavy metals can be subjected to an oxidation reduction or replacement reaction, and the heavy metals in water are removed.
Description
technical field [0001] The invention relates to the field of purification, in particular to a purification device for polyaluminum chloride and a purification method thereof. Background technique [0002] Polyaluminum chloride is one of the main flocculant products at present, and has a wide market in industrial wastewater treatment and drinking water treatment. At present, polyaluminum chloride is mainly prepared by reacting aluminum ore powder, industrial recycled aluminum slag and industrial by-product hydrochloric acid. Due to the complex composition of aluminum ore powder, aluminum slag and industrial by-product hydrochloric acid in this preparation method, they all contain certain Heavy metals, organic matter and other impurities in polyaluminum chloride products usually contain some harmful impurities, which will cause harm to human health or the water environment after use. When the product quality requirements are high, some manufacturers of polyaluminum chloride p...
