Description
Technical field
The present invention relates to water-treatment technology field, particularly to a kind of bitter, concentrated water, seawater desalination system.
Background technology
Underground and surface water resources and be the important component part that utilizes of water resource, play emphatically as productive life use water
The effect wanted.Yet with containing high salinity, high salinity, it is impossible to directly use during life, even cannot be used for production, oil field
Re-injection and irrigated crop, more increase the pressure of water supply.
Electrodialysis plant is the highest to the pre-processing requirements of former water, and desalination scope is wide, and desalination rate can regulate and control as required, but
Electrodialysis process high salinity, high salinity water time, due to electricity characteristic can produce big calorimetric in the case of resistivity is low,
Work efficiency is low, even can produce the problems such as power supply short circuit burns.
Summary of the invention
The deficiency existed for prior art, it is provided that a kind of bitter, concentrated water, seawater desalination system, i.e. solves
Electrodialytic defect problem, to achieve bitter, concentrated water, desalinization again be industry, oil field re-injection water, filling
Irrigate with water, domestic water, drinking water and pure water, both met different demands, and saved again the energy.
The technical scheme is that a kind of bitter, concentrated water, seawater desalination system, including set gradually
Knot screen, rough filtering device, sterilizing unit and electrodialysis plant, described electrodialysis plant connects tank, described rough filtering device
Including medicine machine, Buffer Pool and vortex sedimentation tank, described Buffer Pool front end is provided with coagulant drug-adding device, under vortex sedimentation tank
End has impurity discharging port.
Preferably, also include filtering device, membrane treatment appts and reverse osmosis unit soon, described fast filter device be arranged on described in kill
Between bacterium device and electrodialysis plant, membrane treatment appts or reverse osmosis unit are set between described electrodialysis plant and tank.
Preferably, described tank is industry, oil field re-injection water tank, drinking water reservoir, purified water storage pond
With domestic water tank.
Preferably, described knot screen is macropore screen cloth, and the bottommost of described knot screen is provided with slag-drip opening.
Preferably, described sterilizing unit device is UV steriliser or O sterilizer.
Preferably, described fast filter device includes that ceramic filter, activated carbon filter and ion exchange resin filters, described pottery
Filtering and connect ion exchange resin filtration, ion exchange resin filters connection activated carbon and filters.
What the present invention had has the advantages that: a kind of bitter that the present invention relates to, concentrated water, desalinization system
System, uses electrodialysis plant under applying direct current electric field effect, utilizes the anion and cation exchange membrane choosing to solution middle-jiao yang, function of the spleen and stomach anion
Selecting permeability, make in solution a kind of process that the solute in ionic condition separates with solvent, this process does not has solute in a device
Storage and accumulation, the most there is not the transfer of the change of phase, only ion in solution.Therefore, solution after electrodialysis, one
The solute transfer dividing solution reduces (i.e. desalination process), and the solute of another part solution increases (i.e. concentration process), by ad hoc
Flowing flux dense, fresh water are collected respectively, the concentrated water drainage drained into outside membrane stack falls, and fresh water collecting is achieved that electrodialysis
Desalting process.
Electrodialysis plant is the highest to the pre-processing requirements of former water, and desalination scope is wide, and desalination rate can regulate and control as required.Desalination
Process, without phase transformation, adapts to face width to former water salinity and change thereof, and operating cost is low, the most pollution-free to environment, simple to operate
Etc. major advantage.And desalination degree can be regulated by regulation flow, voltage, current parameters, it is thus achieved that different salt contents
Desalination water.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of bitter of the present invention, concentrated water, seawater desalination system.
Specific implementation method
In conjunction with accompanying drawing, the present invention is described further:
A kind of bitter, concentrated water, seawater desalination system, including the knot screen set gradually, rough filtering device, sterilization dress
Putting and electrodialysis plant, described electrodialysis plant connects tank, and described rough filtering device includes medicine machine, Buffer Pool and vortex
Sedimentation tank, described Buffer Pool front end is provided with coagulant drug-adding device, and there is impurity discharging port vortex sedimentation tank lower end.
Wherein, embodiment 1: be that commercial production, oil field are returned by bitter, concentrated water, Seawater Treatment by the present invention
Note, irrigation water.
A kind of bitter, concentrated water, seawater desalination system, including the knot screen set gradually, rough filtering device, kill
Bacterium device and electrodialysis plant, described electrodialysis plant connects industry, oil field re-injection water tank, and wherein, described coarse filtration fills
Put and include that medicine machine, Buffer Pool and vortex sedimentation tank, described Buffer Pool front end are provided with coagulant drug-adding device, vortex sedimentation tank
There is impurity discharging port lower end；Knot screen is first by the large volume physics filtering foreign such as branch, straw, and knot screen is macropore screen cloth, institute
The bottommost stating knot screen is provided with slag-drip opening；Rough filtering device is further crosses float and microorganism and colloid, protection in drainage
Defecator, fast filter device reduces salinity in former water, reduces the pressure of electrodialysis plant, and this device can.Domestic water stores up
Pond is for bitter, concentrated water, sea water through the storage of the domestic water of membrane treatment appts, and purified water storage pond is used for
