The invention discloses a
water treatment device based on a mechanism of a
photocatalysis reaction of nano-crystalline
titanium dioxide
fiber. The
water treatment device comprises
photocatalysis reactors of the
nanocrystalline titanium dioxide fiber, a
water storage tank, a water pump, a first valve, a second valve, a flow meter, a spraying and aerating head, a water outlet
pipe and a connecting
pipe. The
water treatment device has the advantages that
multiple stages of square
body type reactors are stacked together to realize equal-path parallel circulating water treatment, the number of thereactors can be conveniently increased and reduced, the efficiency of a
photocatalysis circulating water treatment is high due to the adoption of a parallel mechanism, and the continuity is strong;
ultraviolet lamps are horizontally placed above the reactors and parabola-shaped lampshades are adopted, so that light can be vertically incident into liquid levels to the maximal extent; as parallel clapboards are arranged, the flow rates of water flows in the reactions are obviously reduced, breakage and loss of the
fiber, which are caused by overlarge
impact of the water flows, are effectively avoided, and the strokes of the water flows in different time segments are uniform; and the water treatment device can be applied to large-flow dynamic continuous water treatment, makes large-scale treatment of industrial
wastewater containing organic pollutants possible, has a simple structure, requires a low cost and has a broad prospect.
