| titleOfInvention | Composite coagulant for heavy metal-containing wastewater treatment, preparation method and application thereof |
| abstract | The invention discloses a composite coagulant for the treatment of heavy metal-containing wastewater, a preparation method and application thereof. The preparation method of the invention mainly includes the following steps: firstly, using acrylamide as a raw material, an aqueous solution polymerization method is used to prepare a polyacrylamide coagulant. gel, then using the polyacrylamide gel as a reaction monomer, polymerizing the polyacrylamide gel and the reducing oligopeptide to obtain an organic coagulant polyacrylamide-oligopeptide, and at a certain temperature, the polyacrylamide-oligopeptide is mixed with the polyacrylamide-oligopeptide. The inorganic coagulant polyaluminum chloride is mixed with heating and stirring to react to obtain a polymer acrylamide-oligopeptide-aluminum chloride composite coagulant, which can be used in wastewater treatment to achieve the removal rate of heavy metals in industrial wastewater. 90% or more, and the phenomenon of high chemical cost and large amount of sludge will not occur due to excessive dosage of coagulant. The technical solution disclosed in the present invention has the prospect of large-scale industrial production and application promotion. |
