Abstract
The invention discloses green nanocarbon-based film capacitive water treatment equipment. According to the equipment, a carbon nanotube-carbon nanofiber composite film with high specific surface area directly grows on a conductive substrate by adopting a low-temperature low-pressure chemical vapor deposition device and is activated by further using acids and plasmas, an ion exchange membrane is introduced into a capacitive deionization (CDI) technology, a membrane capacitive deionization (MCDI) technology for combining the ion exchange membrane and the CDI technology is formed, and the electrode deionization efficiency can be greatly improved.
Description
Technical field
The present invention relates to a kind of novel desalting technology, relate in particular to a kind of Preen nono carbon-based films electric capacity water treating equipment, utilize carbon nanotube-carbon nanofiber combined electrode to realize efficient, green Demineralized Water Production.
Background technology
Along with expansion and the development of industrial society, the resources such as air, soil, water become the basic strategic resource that concerns national economy day by day.Pure water resources is at the key areas of tie society development, as being absolutely necessary in bio-pharmaceuticals, microelectronics manufacture.If contain the ion of excess in water, not only can cause serious problem in above-mentioned field, also can cause trouble to the mankind in daily life.In common industry or civil running water, contain Ca2+, Mg2+ and some negatively charged ion be as HCO-, if above-mentioned ion can not effectively remove, easily in metal tubulation road or pot scale inside furnace, blocking pipe; If enter human body, easily form calculus or cause other health problems.Now, metallurgy, plating, chemical industry even a large amount of trade effluents containing harmful ion of the industry such as nuclear power discharge especially water surrounding has been caused to great harm.The Zhejiang blood lead of the nearest social extensive concern event such as event and Fukushima, Japan nuclear incident that exceeds standard has been warned the especially deionized significance of desalination of water technology to us again.Meanwhile, due to the shortage of Freshwater resources, want water to become an imperative world subject to sea.In the face of the crisis of water resources, except wanting rationally, water saving, efficient, green Demineralized Water Production technology is developing water resources, purifies waste water, the important channel of protection people's life safety.And on the other hand, resource circulation utilization is the theory that society is advocated, in efforts at environmental protection, often industrial effluent is carried out to the refinement enrichment of element, with recycling.By the method for capacitive adsorption-desorption, it is a kind of effective method that effects of ion is carried out to enrichment.
Summary of the invention
For the problem of above-mentioned existence, the object of this invention is to provide a kind of novel desalting technology that can promote on a large scale, it is advantageous that ion remaval rate: > 90%(ionic concn is not less than 100 ppm); Current consumption: 0.7 degree electricity/ton water; Water use efficiency: 90%; Can automatically control desalination and the regenerative process of MCDI.
The object of the invention is to be achieved through the following technical solutions:
Chemical vapor deposition for carbon nanotubes-carbon nanofiber combined electrode.Adopt low-temp low-pressure chemical vapor deposition unit direct growth in conductive substrates to there is carbon nanotube-carbon nanofiber laminated film of high-specific surface area, and further use acid and plasma-activated processing, can be used as more satisfactory carbon composite electrode material.
Membrane capacitance deionized water treatment unit.CDI desalting technology is a kind of desirable desalting technology.Ion-exchange membrane is incorporated in CDI technology, has formed the MCDI technology that ion-exchange membrane is combined with CDI technology, can greatly improve the efficiency of electrode removal ion, there are some researches show that the desalination rate of MCDI can improve 50% left and right on the basis of CDI.Have membrane capacitance desalting technology, and practical by design device and peripheral circuit, can further improve existing water body desalting technology.
The pilot circuit of desalting plant, the function of the collection of realization to data and the control to external equipment and indicating system state, realizes automatization control.
Embodiment
Below in conjunction with principle and concrete operations embodiment, the invention will be further described.
Low cost: working cost is low, processes 1 ton of water power consumption and is less than 0.7 degree electricity, lower than electrodialytic technique (1 degree electricity/ton); Aspect manufacturing cost, membrane capacitance deionization (Membrane Capacitive Deionization:MCDI) device has reached the level of electrodialysis device in desalination rate, but cost is far below the latter (price is only electrodialytic 1/10 left and right)
High-level efficiency: electro-adsorption demineralization rate reaches more than 90%, water use efficiency high (85%-90%);
Environmental friendliness: electrode can repeat regeneration, long service life (some months continuously tested shows: surface do not come off, non-foaming);
Novel in design: designed, designed process water processing apparatus, can realize personalization, multi-functional combination and realize automatization control.
Above specific embodiments of the invention be have been described in detail, but the present invention is not restricted to specific embodiment described above, it is just as example.To those skilled in the art, any to this equivalent modifications of carrying out and alternative also all among category of the present invention.Therefore, equalization conversion and the modification done without departing from the spirit and scope of the invention, all should contain within the scope of the invention.
