In one embodiment, precise filtering device uses the QC secondary filter of Beijing Qing Cheng Time Technology Development Co., Ltd
Device, the filter device is using soft material fiber and particulate filler as filtration system unit, and filtering accuracy is at 0.5 μm hereinafter, solution
The problem of filtering accuracy of the partial sizes filtrate such as sand filtration of having determined is limited by particle diameter of filter medium；Filtering accuracy is high, and the rate of filtration is fast, cuts dirty hold
Amount is big, and occupied area is small, and ton water low cost is not subject to processing the limitation of water, and filtering element does not need to replace, and water consumption is low, performance
It is unattenuated.QC precise filtering device can effectively remove the suspended matter in water, and have to organic matter, colloid, iron, the manganese etc. in water
Apparent removal effect, is effectively reduced the turbidity of water；It can be widely used for municipal sewage, industrial wastewater recycles, urban river water is net
Change, landscape water process etc., reverse osmosis pretreatment is used in the present embodiment.
Ozone (O3) be oxygen allotrope, it is a kind of light blue gas with special odor.Molecular structure is in
Triangle, bond angle are 116 °, 1.5 times of density foot oxygen, 10 times of the solubility foot oxygen in water.Ozone foot is a kind of strong
Oxidant, its oxidation-reduction potential in water are 207V, are only second to fluorine (2.5V), oxidability be higher than chlorine (1.36V) and
Chlorine dioxide (1.5V), can destroy the cell wall of decomposing bacteria, and soon diffusion penetrates into intracellular, oxygen inside oxygenolysis bacterium
Change glucose oxidase necessary to glucose etc., can also directly have an effect with bacterium, virus, destroys cell, ribose core
Sour (RNA), the macromolecule polyalcohols such as decomposition DNA (DNA), RNA, protein, lipid and polysaccharide, makes bacterium
Metabolism and reproductive process are destroyed.Bacterium kills foot caused by the fracture of cell membrane by ozone, this process is referred to as cell
Dissipate, be due in cytoplasm water be crushed caused by;Cell can not regenerate under conditions of dissipation.It should be pointed out that with
