Preparation method of polymeric aluminum ferric sulfate composite water purifying agent

Abstract

The application discloses a preparation method of a polymeric aluminum ferric sulfate composite water purifying agent and belongs to the technical field of water purifying agents. The preparation method comprises the following raw materials in parts by weight: 33-45 parts of polymeric aluminum ferric sulfate, 21-37 parts of modified polyacrylamide and 80-100 parts of deionized water. The prepared water purifying agent combines aluminum, iron and polyacrylamide water purifying agents, and the three kinds of water purifying agents can synergistically improve the water purifying performance. The cationic modification of the polyacrylamide not only makes the flocculation effect of the polyacrylamide stronger, but also has the bactericidal performance. In summary, the prepared water purifying agent combines the advantages of the three kinds of water purifying agents, has excellent flocculation effect and bactericidal performance, overcomes the defects of single component, can adapt to more complex water quality and has important application value in the technical field of water purifying agents.
