Abstract
The invention relates to a solar energy photocatalysis plant water purifying method. A solar energy photocatalysis plant floating bed is arranged on the fish-farming water surface and provided with an inflating water lift system and a solar energy photovoltaic generating system, and sponge foam, a nacreous glass catalytic reaction curtain and water plants which are sequentially arranged. Solar energy photovoltaic generation drives an inflating pump to work so as to send air into a gas release stone which is placed in a water lift pipe. Micro-bubbles rise by carrying water and lift and send the water to the floating bed. Through the sponge foam and the nacreous glass catalytic reaction curtain, the intercepted solid impurities filtered by the sponge plastic foam are discharged. The water is contacted and reacts with TiO2 photocatalysis films coated on glass balls so as to degrade organic pollutants in the water into small molecule inorganic nitrogen and mineralizers. The treated water by photocatalysis flows through the water plants, and the nutrition of the water is absorbed by the plants. The purified water flows out of the floating bed and falls back to the fish-farming water area. The method can directly utilize the solar energy to filter and purify and oxygenate on the fish-farming water surface, and also be used for the water quality treatment of environmental protection and greenbelt landscape water areas.
