Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1, the present invention provides a kind of three unit desalination plants, including pretreatment unit 1, desalination unit
2 and allocation unit 3.Pretreatment unit 1 includes sequentially connected water pump 11, air supporting 12 and raw water box 13, can pass through water intaking
Pump 11 inputs seawater in air supporting 12, and air supporting 12 can effectively remove extra large Organic substance in water, such as seaweed etc. can reduce follow-up anti-
The live load of permeable membrane is conducive to extend its service life, while after getting rid of organic matter, smelling as of rotten fish in the fresh water of reverse osmosis formation
Taste is significantly desalinated, it is stored in raw water box 13 after the processing of air supporting 12, for use；Desalination unit 2 includes sequentially connected
More medium filter 21, cartridge filter 22 and counter-osmosis device 23, the more medium filter 21 are connect with the raw water box 13,
It can remove part fiber fines, the suspended matter in raw water box 13, and cartridge filter 22 can then retain the suspension in seawater
Object, larger molecular organics etc. carry out secondary filter processing, and to reduce the turbidity of water, counter-osmosis device 23 can will then go to deimpurity sea
Water is concentrated, and the fresh water after concentration can be used as drinking water, and concentrated water can drain into ocean；Allocation unit 3 includes being sequentially connected
Mineralization filter 31, water tank 32 and constant pressure water supply mechanism 33, and the mineralization filter 31 and the counter-osmosis device
23 water outlet connection, due to excessively pure in the fresh water after 23 reverse-osmosis treated of counter-osmosis device, what is contained is beneficial
Mineral ion concentration is too low, is unfavorable for supplementing needed by human body minerals, therefore the present embodiment is suitably carried by mineralization filter 31
It is high it is reverse osmosis after beneficial mineral matter ion concentration in fresh water, while its can to reduce hydrogen ion in reverse osmosis freshwater to a certain degree dense
Spend high problem；Water after mineralising can be directly stored in water tank 32, and extremely by the distribution of constant pressure water supply mechanism 33
Different users can guarantee the pressure stability to supply water, and avoid using high water tank, have the effect of energy saving, at low cost.
During water pump 11 is fetched water, part marine organisms easily enter in water pump 11, easily lead to and increase subsequently
Sea water preprocessing difficulty, therefore pretreatment unit 1 described in the present embodiment further includes the anti-of the water inlet end set on the water pump 11
