Problems solved by technology

As a coagulant, the advantages of polyaluminum chloride and polyaluminum ferric chloride are that the hydrolysis speed is fast, the alum flowers formed are denser, the sedimentation speed is fast, and it is less affected by the change of water temperature. It is suitable for raw water with various turbidities. The pH range is wide, but compared with polyacrylamide, its sedimentation effect is far less than that of polyacrylamide
[0004] At the same time, since the water purifying agent added contains a large amount of metal aluminum and iron, it settles in the sludge after flocculation, which brings difficulties to the subsequent sludge treatment. Fast speed, good purification effect, recyclable and environmentally friendly water purifier

Abstract

The invention discloses a recyclable environment-friendly water purifying agent. The recyclable environment-friendly water purifying agent is of a core-shell structure. Core layers of the core-shell structure are nanometer magnetic particles, shell layers of the core-shell structure are emulsion liquid membranes, and inorganic polymer coagulants are deposited outside the emulsion liquid membranes.The recyclable environment-friendly water purifying agent has the advantages that the release amount of inorganic polymer coagulant water purifying agents can be reduced, dense alum floc can be formed, the recyclable environment-friendly water purifying agent is high in sedimentation velocity, and good purification effects can be realized by the recyclable environment-friendly water purifying agent; the nanometer magnetic particles of the core layers of the recyclable environment-friendly water purifying agent are easy to enrich and recycle. The invention further discloses a method for preparing the recyclable environment-friendly water purifying agent.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a recyclable and environmentally friendly water purifier and a preparation method thereof. Background technique [0002] Water purifiers are chemicals that can react with other impurities in water when put into water. Mainly for the purpose of water purification. Commonly used water purifiers include polyaluminum chloride, polyaluminum ferric chloride, basic aluminum chloride, polyacrylamide, ferrous sulfate, aluminum sulfate, polyferric sulfate, etc. [0003] Polyaluminum chloride is an inorganic polymer coagulant, referred to as polyaluminum, and the English abbreviation is PAC (poly aluminum chloride), which is between AlCl 3 and Al(OH) 3 A water-soluble inorganic polymer among them. Poly Ferricaluminum Chloride (Poly Ferricaluminum Chloride, PAFC) is an aluminum-iron copolymer inorganic polymer coagulant formed by hydrolyzing and polymerizing aluminum and iron sal...
