(1) Drinking water safety
At present, water treatment technology can not remove trace residual organic pollutants and disinfection by-products such as trihalomethanes, haloacetic acids, aldehydes and bromate. The control and elimination of organic pollutants and disinfection by-products is the main problem facing the drinking water industry, which directly affects human health and the sustainable development of society. Our nano-TiO2 has excellent performance and can be applied in the field of water treatment.
(2) Treatment of eutrophic water in lakes and rivers
Our nano titanium oxide filter can float on the surface of water without particle pollution. It can directly use sunlight to decompose pollutants in water and purify water quality. It is suitable for eutrophication of large lakes and water treatment of urban rivers.
(3) Aquaculture water treatment
Aquaculture wastewater is rich in a large number of pathogens and high concentration of organic matter containing ammonia nitrogen. If it is washed into the water body by rainwater, it may cause serious deterioration of surface water or groundwater quality. Our nano titanium oxide filter can float on the surface of water without particle pollution. It can directly use sunlight to decompose pollutants in water and purify water quality.
(4) Nutrient solution water treatment
The main problem in the use of nutrient solution is the treatment of nutrient solution water. If it is not drained, recycling will reduce the yield of fruits and vegetables; if the sewage is discharged regularly, it is easy to cause environmental pollution. Photocatalyst is used to treat circulating water, and a cleaning system is established to remove harmful substances to growth, so as to improve the utilization rate of nutrient solution water and purify the environment.
