Abstract

The invention discloses an antibacterial filter core and its preparation method and application. The antibacterial filter core has a strong antibacterial effect, has a strong killing effect on Escherichia coli and Staphylococcus aureus in a short time and is suitable for water purification. The antimicrobial filter core comprises nanometer copper-carbon composite particles and cellulose. A weight ratio of the nano-copper-carbon composite particles to the cellulose is (8-12): 1. The particle sizes of the nano-copper-carbon composite particles are 20 to 50nm. The preparation method comprises uniformly mixing a nano-copper-carbon composite material and cellulose, putting the mixture in a mold cavity, carrying out calcination and carrying out cooling, drying and molding.

Description

technical field [0001] The invention relates to an antibacterial filter element, a preparation method of the antibacterial filter element and an application of the antibacterial filter element in a water purification device. Background technique [0002] China's water resource issues are facing severe challenges, and drinking water safety is China's top priority. According to the World Health Organization survey, 70% of the world's diseases are related to drinking water pollution. The number of cholera, dysentery and malaria caused by water pollution in the world exceeds 50 million. In China, 190 million people get sick every year, and 60,000 people die from diseases caused by water pollution. The Chinese government has included drinking water safety in major scientific and technological projects. [0003] The use of low-cost, low-carbon water purification filter elements to maximize the quality of drinking water is the research direction of filter elements. At present, t...
