Embodiment 1

[0038] A kind of water filter material, see attached figure 1 As shown, it is a transmission electron microscope image of an activated carbon material loaded with 0.5% metallic copper and 0.5% metallic zinc. The black dots in the figure are copper particles or zinc particles, and these metal particles are firmly attached to the surface of activated carbon or embedded In its pores, its diameter is mostly between 20-50nm.

Embodiment 2

[0040] A kind of water filter material, see attached figure 2As shown, it is a transmission electron microscope image of an activated carbon material loaded with 0.5% metallic copper and 0.5% metallic silver. The black dots in the figure are copper particles or silver particles, and these metal particles are firmly attached to the surface of activated carbon or embedded In its pores, its diameter is mostly between 20-50nm.

Abstract

The invention relates to a water filter material, belonging to the field of water treatment materials. The invention aims to solve the problem of unideal sterilization and heavy metal removal effects in the existing water filter material, and provides a water filter material with excellent sterilization effect and heavy metal removal effect. The water filter material is characterized by comprising a carbon material substrate, wherein nano metal particles of at least two of silver, copper, zinc and iron are carried on the surface and pores of the carbon material substrate, and the nano metal particles account for 0.1-5 wt% of the carbon material substrate. The water filter material provided by the invention can be used for filtering and sterilizing swimming poll water and landscape water, and can also be used for treating domestic sewage, industrial wastewater, medium / high-concentration heavy metal wastewater and other types of sewage to achieve the goal of discharge after reaching the standard; and the drinking water purified by the water filter material can not jeopardize the body after being drunk directly. Besides, the water filter material can also be used for emergency protection for heavy metal pollution of underground water and surface water.

Description

technical field [0001] The invention relates to the field of water treatment materials, in particular to a water filter material with excellent bactericidal effect and heavy metal removal effect. Background technique [0002] Water is the source of life, and human beings cannot survive without water. With the development of social economy and the continuous improvement of living standards, people's requirements for drinking water are also continuously improved. However, according to a May 2012 report by China Youth Daily, the drinking water of China's approximately 300 million rural population and 50 million urban population still does not meet safety standards. The "2010 China Rural Poverty Monitoring Report" shows that as of 2009, only 32% of all rural households drink tap water, and the rest of the rural households who drink directly from water sources all suffer from varying degrees of health problems. Due to the lack of centralized water supply in rural areas, water p...
