Description

Technical Field

[0001] The invention relates to the technical field of water purification, and in particular to a water purification device for degrading water pollutants by doping titanium dioxide with biochar. Background Art

[0002] With the rapid development of industrialization and urbanization, water pollution is becoming increasingly serious. There are many pollutants in water, including organic pollutants, heavy metal ions, etc. Traditional water purification methods have many limitations. For example, some physical methods can only remove larger particles of pollutants and the removal effect is poor.

[0003] Titanium dioxide is a common photocatalyst with good catalytic activity. It can produce strong oxidizing free radicals under light conditions, thereby degrading organic pollutants. However, there are some problems when using titanium dioxide. The high recombination rate of photogenerated carriers limits its catalytic efficiency. Biochar is a carbon-rich material produced by the pyrolysis of biomass under anaerobic or anaerobic conditions. It has a large specific surface area and good adsorption properties. Doping titanium dioxide with biochar can combine the advantages of both and improve the degradation efficiency of water pollutants. However, there is currently a lack of water purification devices specifically for use with this composite material. Therefore, technicians in this field provide a water purification device for degrading water pollutants using titanium dioxide doped with biochar to solve the problems raised in the above background technology.
