Raw water is lifted by a raw water pump and then sequentially filtered by quartz sand and activated carbon, then enters a reverse osmosis membrane assembly by a high-pressure pump for treatment, purified water penetrating through a reverse osmosis membrane sequentially passes through a plurality of water production tanks, residual concentrated water with higher mineral content sequentially passes through a plurality of ultrafiltration membrane assemblies, each ultrafiltration membrane assembly corresponds to one water production tank, clear water which is obtained by filtration of each ultrafiltration membrane assembly and is rich in mineral is mixed with purified water in the corresponding water production tank, and concentrated water produced by treatment of each ultrafiltration membrane assembly enters the next-stage ultrafiltration membrane assembly. The concentrated water becomes gradually concentrated, and the mineral content in the concentrated water also becomes gradually higher. The concentrated water treated by the last stage of ultrafiltration membrane component is discharged into a sewage tank. By adopting the scheme, various drinking water with the mineral content from low to high is sequentially obtained in the water producing tanks and is respectively conveyed to water consumption points through the water supply pump, so that various choices are provided for users.

The aperture of the ultrafiltration membrane component allows mineral substances to pass through, but the content of harmful impurities such as nitrate in the obtained filtered water can not reach the national allowable standard. Because the reverse osmosis device can remove the nitrate in the water by 95-99 percent, has extremely high removal rate of other harmful impurities which are far beyond the national standard, but most mineral substances are filtered out, the ultrafiltration membrane can be mixed into the reverse osmosis membrane filtered water, thereby not only meeting the national standard, but also obtaining the drinking water with specific mineral content.

In the embodiment, most of inorganic salts and almost all organic matters, microorganisms and colloids can be removed from the water subjected to reverse osmosis treatment, and the process requires that the output of a reverse osmosis device is 2.5m3/h and the conductivity of the produced water is 10-100 mu s/cm. The reverse osmosis membrane component consists of a frame, a reverse osmosis membrane and a membrane tube, and is provided with a related flow meter, a conductivity meter, a pressure meter and a related control element.

The reverse osmosis membrane has the selectivity permeability to the ion of aquatic, therefore has the osmotic pressure difference at reverse osmosis concentrate side and product water side, just so must have external pressure to overcome the osmotic pressure difference and just can make reverse osmosis unit normally work and reach the designing requirement, and external pressure is provided by the high-pressure pump, and according to RO calculation result, reverse osmosis unit inlet water pressure is 13bar, and inlet water pressure after two years rises to 15bar.

The reverse osmosis membrane component is provided with 10 high-pressure composite membranes 4040 and is installed in a glass fiber reinforced plastic pressure vessel.
