Problems solved by technology

Although this application has a certain water purification effect, there are many raw materials, complicated preparation process, and high production cost, and the phytostatic agent used is only one or more of Eupatorium adenophorum stems and leaves, Moringa seeds, mugwort leaves, and aloe vera. This mixture has poor antibacterial effect and cannot meet the antibacterial requirements of water purifiers

Abstract

The invention relates to the technical field of water purification treatment, and particularly discloses a bacteriostatic water purifying agent and a preparation method thereof. The preparation method of the antibacterial water purifying agent comprises the following steps: S1, dissolving chitosan in an acetic acid aqueous solution, stirring, then adding a sodium tripolyphosphate aqueous solution, and carrying out ultrasonic treatment to obtain a nano chitosan solution; and S2, adding acrylamide, a cationic monomer, a template agent, a bacteriostatic agent and an additive into the nano chitosan solution, stirring, introducing nitrogen, adding an initiator, sealing, placing in an ultraviolet light initiation device for radiation reaction, standing after the reaction is ended, and washing, drying and crushing a product to obtain the bacteriostatic water purifying agent. According to the technical scheme, the preparation technology is simple, the raw material utilization rate is high, and the prepared water purifying agent has the double functions of flocculation and bacteriostasis and is good in market prospect.

Description

technical field [0001] The invention relates to the technical field of water purification treatment, in particular to an antibacterial water purifier and a preparation method thereof. Background technique [0002] Water resources are important material resources of natural ecosystems, and also important basic material resources supporting the development of human economic and social systems. With the acceleration of industrialization, a large amount of sewage is directly or indirectly discharged into rivers, lakes and seas, resulting in serious pollution of fresh water. Water purifying agent is an important class of fine chemical products, which play an important role in the purification treatment of industrial sewage and domestic wastewater. The large-scale use of water purifiers not only provides humans with a large amount of clean drinking water, industrial and agricultural water, greatly alleviates the environmental hazards of polluted water bodies, but also effectively...
