The invention relates to a method for deep purification of drinking water by adopting an oxidation-resistant film, which comprises the following steps: conveying
raw water and leading the
raw water to enter into a contact tank, inputting gas containing
ozone via a microporous aerator for carrying out
ozone aeration, and carrying out oxidation and degradation on organic matters in
water flow; further leading the
water flow to enter into an oxidation-resistant film filtering component above the microporous aerator for
filtration; and leading the
water flow after the
filtration by the oxidation-resistant film to enter into a
granular activated carbon filtering
bed layer for adsorption and microbial purification, effectively removing the residual organic matters and
ammonia nitrogen and obtaining the drinking water after deep purification. The method can realize the deep purification of a
water source with micro-
pollution through an
ozone, oxidation-resistant film and
granular activated carbon combined
system, break through the limitations of the commonly used
organic film treatment, not only remove the
turbidity in the
raw water, but also effectively remove the high-concentration organic matters and the
ammonia nitrogen in the raw water; furthermore, the method can carry out transformation on the basis of the conventional process of the existing water
plant, does not need to carry out major adjustment on main structures of the water
plant, and is convenient for popularization.
