Embodiment Construction
[0016] Embodiments of the present invention; 1. A treatment method for household water purification, characterized in that: the method is to first pass tap water into a polypropylene cotton filter rod, and remove suspended solids and large particles in the tap water by the polypropylene cotton filter rod Impurities, and then the tap water filtered through the polypropylene cotton filter rod is pressurized and then input into the oxidation-resistant composite reverse osmosis membrane, and the inorganic salts, heavy metal ions, organic substances, colloids, bacteria and viruses in the tap water are eliminated through the oxidation-resistant composite reverse osmosis membrane. At the same time, the residual chlorine in tap water is used to control and kill the microorganisms attached to the surface of the oxidation-resistant composite reverse osmosis membrane during the filtration process. The purified water filtered by the oxidation-resistant composite reverse osmosis membrane is ...

The present invention discloses household water purifying process and system. The water purifying process includes filtering tap water with polypropylene cotton filter element to eliminate suspended matter and large granule impurity, pressurizing water, filtering water with antioxidant composite reverse osmosis film for the second time while controlling and killing microbe in the surface of the antioxidant composite reverse osmosis film with residual chlorine in water, and storing in a pressure tank. Before being use, the water is further filtered through an active carbon filtering rod to eliminate residual chlorine. The water treating process and system is simple and the reverse osmosis film has less pollution.
Description
technical field [0001] The invention relates to a treatment method for household water purification and a treatment system thereof, belonging to the technical field of water treatment. Background technique [0002] Because the household pure water machine is easy to use, the operating cost of water production is low, and it can be directly installed in the cabinet, which not only saves space, but also is beautiful and generous, and is more and more popular among consumers. [0003] The current domestic pure water treatment system is mainly composed of three parts: water pretreatment, reverse osmosis filtration and pure water storage. Usually, the tap water in the tap water pipe is passed through a pp cotton filter element to filter out suspended solids in the water. Because the reverse osmosis membrane element has strict requirements on the free chlorine content of the feed water, the residual chlorine content is required to be less than 0.1mg / L, otherwise the membrane will ...
