Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.

As shown in fig. 1 and 2, a drinking water purifying device with both nanofiltration and reverse osmosis comprises a raw water pump 1, a nanofiltration filter 2, a reverse osmosis filter element 3 and a control system 4, wherein a raw water tank 5 is connected to a water inlet end of the raw water pump 1, a purified water tank 6 is connected to a water outlet end of the reverse osmosis filter element 3, a water outlet end of the raw water pump 1 is connected to a water inlet end of the nanofiltration filter 2, a water outlet end of the nanofiltration filter 2 is connected to a water inlet end of the reverse osmosis filter element 3, and an ultraviolet sterilizer 7 is arranged between the reverse osmosis filter element 3 and the purified water tank 6. When the liquid level signal of former water tank 5's level gauge is less than well liquid level control system 4 opens the solenoid valve of intaking, closes the solenoid valve of intaking when being higher than the high liquid level, simultaneously when the liquid level signal of former water tank 5's level gauge is less than low liquid level control system 4 reports to the police, and alarm frequency is once for 2 hours, and until the liquid level is higher than well liquid level signal.

The nanofiltration filter 2 filters out foreign matters such as suspended matters, insoluble particles, flocculent precipitates and the like in water, the efficiency of removing chromaticity, natural organic matters, synthetic organic matters (such as pesticides and the like), three-cause substances, disinfection byproducts (trihalomethane and haloacetic acid) and precursors and volatile organic matters thereof can reach 99.9 percent, and the biological stability of drinking water is ensured. The nanofiltration filter 2 is prepared by a unique ceramic sintering process, because the diatomite contains a micron-sized cellular porous structure, the special process technology is adopted to embed the special activated carbon containing a large number of nano micropores in the diatomite, the idea that the surface of the traditional ceramic membrane is only used as an active layer is overturned, the middle layer of a three-dimensional structure is innovatively used as an active adsorption and filtration layer, the inner and outer extremely thin membrane layers are used as protection layers, and the traditional inorganic ceramic membrane preparation process is adopted to sinter and form the diatomite activated carbon on the premise of protecting the core nano micropore activated carbon from any damage. Therefore, the unique structure of the nano filter element prolongs the filtering path of the inlet water to achieve a filtering path similar to a labyrinth, thereby increasing the contact time and the contact area of the water and the active carbon and furthest removing the chemical micro-pollution in the water. The nanofiltration filter 2 can remove pigments, organic matters and heavy metal ions in water, simultaneously play the super-strong adsorption and antibacterial functions, remove residual chlorine in water and inhibit breeding of bacteria. Therefore, the nano filter element can really achieve the effects of selective separation, namely 'nano mineral substance and micro pollution filtration'. Moreover, the water purification process does not use electricity and discharge waste water, and the method conforms to the environmental protection concept of low carbon and energy saving. The common tap water is subjected to super strong adsorption, labyrinth filtration and selective separation by the nano filter element, the water quality of the common tap water is comparable to that of natural mineral water which is not polluted, and the common tap water is crystal, clean and sweet in taste.

The operating principle of the reverse osmosis filter element 3 is as follows: when the same volume of dilute solution (e.g., fresh water) and concentrated solution (e.g., saline) is placed on each side of the semi-permeable membrane, the solvent in the dilute solution will naturally flow through the semi-permeable membrane spontaneously to the concentrated solution side, a phenomenon known as osmosis. When the osmosis reaches the equilibrium, the liquid level of the concentrated solution side is higher than the liquid level of the dilute solution by a certain height, namely, a pressure difference is formed, and the pressure difference is the osmotic pressure. The magnitude of the osmotic pressure depends on the inherent properties of the solution, i.e. on the type, concentration and temperature of the concentrated solution and not on the properties of the semipermeable membrane. If a pressure greater than the osmotic pressure is applied to the concentrated solution side, the solvent will flow in the opposite direction to the original direction of osmosis, and will start to flow from the concentrated solution to the dilute solution side, a process known as reverse osmosis. The reverse osmosis filter element 3 is a reverse migration movement of osmosis, is a separation method for separating solute from solvent in solution by means of selective interception of semipermeable membrane under pressure driving, and is widely applied to purification and concentration of various liquids, wherein the most common application example is to remove impurities such as inorganic ions, bacteria, viruses, organic matters, colloid and the like in raw water by using reverse osmosis technology in a water treatment process to obtain high-quality purified water.

The sterilization principle of the ultraviolet sterilizer 7 is to utilize the energy of ultraviolet photons to destroy the DNA structures of various viruses, bacteria and other pathogens in the water body. Mainly makes various structural bonds in DNA break or generate photochemical polymerization reaction, for example makes THYMINE in DNA dimerize, so that various viruses, bacteria and other pathogenic bodies lose replication and reproduction capability, and the effect of sterilization is achieved.

The high-pressure pump 10 is protected by the low-pressure switch 12 for water inflow and the high-pressure switch 13 for membrane water inflow pressure, namely when the water inflow pressure of the pump reaches a set value of 0.15MPa (adjustable), the high-pressure pump 10 is started, otherwise, the operation is stopped; when the forward water pressure of a reverse osmosis system membrane exceeds 1.2MPa, the high-pressure pump 10 stops running, if the high-pressure pump 10 is started and stopped frequently, the high-pressure pump is started and stopped continuously for more than 3 times within 1min, the control system 4 controls the whole system to stop and give an alarm, and the reverse osmosis system can run again in need of manual reset.
