Description
Technical field
The utility model relates to filter, especially a kind of cascade filtration device that possesses filtration and degerming dual-use function.
Background technology
Existing drinking water method for disinfection generally includes chlorine sterilization, ultraviolet sterilization, ozone sterilization, but all there is certain disadvantage, as: the chlorine sterilization, remaining free chlorine can have side effects to health, and very strong oxidation arranged, in some commercial Application, do not allow to exist, have certain limitation.Ultraviolet sterilization apparatus is owing to be subjected to the restriction of its wavelength, and sterilization does not possess broad spectrum activity, and may be subjected to factor affecting such as water velocity, uviol lamp are aging, causes its bactericidal effect instability.Ozone sterilization though its bactericidal effect is superior, generally contains bromide in the water, under certain condition, bromide in the water and ozone reaction can generate bromate after the oxidation.And bromate has been decided to be the potential carcinogen of 2b level by international cancer research institution.Research is thought, the women of child-bearing age, pregnant woman, immunologic hypofunction person, child and old people, may be subjected to the influence of bromate especially easily, cause nauseating, vomiting, stomach and intestine misery, anuria, diarrhoea, central nervous system depression, hemolytic anemia, pulmonary edema, renal failure easily and become deaf.If guarantee that bromate does not exceed standard, then ozone amount can not be too high, makes bactericidal effect be difficult to guarantee that the bacterium index may exceed standard, and makes These parameters become to be difficult to the problem of balance like this.
At present, the drinking water source is subjected to serious industrial pollution, and drinking water source heavy metals exceeding standard problem constantly appears in all parts of the country, and children's heavy metal poisoning incident idol has generation.And the water resource that to be human survival indispensable and the important leverage of human health, as seen, how important the cleaning that guarantees our Drinking Water is.
Now a kind of average pore size being arranged on the market is two controlling diaphragm ceramic elements of 0.1 μ m, pathogenic bacteria such as the Escherichia coli in the filtering water, staphylococcus aureus, salmonella typhi, cholera bacteria, Legionnella fully, various suspended contaminant such as iron rust, insects, algae and dust in the filtering water comprehensively, water behind this filter element filtering need not to boil, promptly reaching the standard of national direct drinking water fully, is aseptic, clean, the safe drinking water that can directly drink.At present, its finished product only is the combination of single filter core and corresponding shell, is called for short the two controlling diaphragm ceramic filters of single-stage below, as shown in Figure 1.
Some twin-stages or multistage filter are also arranged now, add in two controlling diaphragm ceramic elements front and to put lower slightly film built-in ceramic filter core or the conventional ceramic filter core of filtering accuracy, it is one in front and one in back assembled into a double filter with independent external series system with two controlling diaphragm ceramic elements, or functional filter elements such as film built-in ceramic filter core, resin are assembled into tertiary filter with two controlling diaphragm ceramic elements by independent external being connected in series of above-mentioned ordering, as shown in Figure 2.
For the two controlling diaphragm ceramic filters of single-stage, though can reach the effect of filtering bacterium and heavy metal,, use the so accurate two controlling diaphragm ceramic filter filter cores of single-stage like this, result in blockage easily, need often to clean, and the mouthfeel of water is improved more limited.Then there are the cost height in two-stage or multistage filter for the independent external series system of filter core, and big defective takes up room.
