Embodiment Construction
[0015] An embodiment of the present invention; a treatment method for water treatment with an oxidation-resistant composite reverse osmosis membrane. The method is to add a flocculant in the water supply pipe to be purified, so that the suspended solid particles and metal ions in the water to be purified are mixed with the flocculant to form a precipitate, and then the water to be purified mixed with the flocculant is passed through a multi-media filter to remove Suspended solids or sediments in the water, and then add a certain amount of sodium hypochlorite and scale inhibitor to the water to be purified after the multi-media filter, and then mix through the mixer, and then enter the security filter to remove the small particles in the water, and then enter the reactor. Permeation system; the inorganic salts, heavy metal ions, organics, colloids, bacteria and viruses in the water to be purified are filtered through the oxidation-resistant composite reverse osmosis membrane, and t...

The invention discloses a treatment method and a treatment system for water treatment using an oxidation-resistant composite reverse osmosis membrane. The method is to add a certain amount of sodium hypochlorite to the water to be purified, and mix the water to be purified with the added sodium hypochlorite through a mixer. The security filter device performs secondary filtration, enters the oxidation-resistant composite reverse osmosis membrane, and filters the water to be purified through the oxidation-resistant composite reverse osmosis membrane. And kill, and then filter the purified water filtered by reverse osmosis through the activated carbon filter tank, and remove the residual chlorine in the purified water through the activated carbon filter tank, and finally make the purified water meet the use requirements. The invention not only simplifies the process of the water treatment system, saves equipment investment, equipment maintenance costs and floor area, but also reduces cleaning frequency and prolongs the service life of the reverse osmosis system.
Description
Technical field [0001] The invention relates to a water treatment purification treatment method and a device thereof, in particular to a water treatment method and a treatment system using an oxidation-resistant composite reverse osmosis membrane. Background technique [0002] A reverse osmosis membrane is a pore size as small as nanometers. Under a certain pressure, water molecules can pass through the surface of the membrane, thereby removing inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses and other impurities in the water. Therefore, reverse osmosis technology occupies an important position in the water and liquid separation domain with its new, high-efficiency and energy-saving separation technology. It is currently widely used in many fields such as seawater desalination, reclaimed water reuse, and micro-polluted surface water treatment. [0003] However, microbial contamination in the use of ordinary reverse osmosis membranes is one of the mai...
