Description
Technical field
The present invention relates to a kind of water treating device, specifically, relate to a kind of device for desalination treating sea water with fibre cloth block.
Background technology
Water is Source of life, and the source of development is the lifeblood of socio-economic development, is human valuable and irreplaceable natural resources.Water shortage problem is a worldwide problem, has become the bottleneck of restriction social progress and Economic development.Improving constantly of the development that continues along with economy and people's people's livelihood words level, also increasing to the demand of the water yield, also more and more higher to requirements in water quality; And the deficiency of water resources, space-time divides the inequality of Fabric, adds the exploitation of infinity, immoderate waste, and random pollution makes the water resources imbalance between supply and demand of original anxiety more sharp-pointed.Therefore, solving the imbalance between supply and demand of water resources, is the task of top priority of the sustainable development of China's economy.
Although earth surface is 2/3 awash, 97% is salt water (comprising seawater and brackish water) in the total reserves of earth water; And account in 3% the fresh water, have 77% to be the two poles of the earth ice sheet, glacier, the ice and snow that the mankind are difficult to utilize again.Human actual available fresh water only takes up an area of 0.7% of ball water inventory, and major part belongs to non-renewable exhaustion underground water.The 47th United Nations General Assembly is decided to be " World Water Day " with the March 22 in every year, has further caused the attention of countries in the world to water.20 beginnings of the century just had 19th century to strive coal in the world, and 20th century were striven oil, and 21 century is striven the saying of water.Reality shows that 21 century will be the century of " sea water desaltination ".
The mankind observe a kind of phenomenon very early, if container is separated with a semi-permeable membrane, contain to contain salinity high water on one side, contain on one side to contain the low water of salinity; Containing the low water of salinity will permeate on one side to containing the high water of salinity, when the both sides saltiness equates till.With a kind of selection perviousness film with a container dimidiation, both sides at film add pure water and salt solution simultaneously respectively, make the liquid level of film both sides equally high, crossed certain hour and the liquid level of brine side can take place in rising, the liquid level of pure water side is descending, this is that this phenomenon claims infiltration because water molecules sees through the result of semi-permeable membranes to the brine side migration.On the contrary, when exerting pressure to brine side and making pressure surpass brinish osmotic pressure, then the water molecules of brine side sees through semi-permeable membranes to the pure water side under pressure-driven, and this process is reverse osmosis.
Because the impellent of reverse osmosis process is a pressure, undergoing phase transition not in the process, film only plays a part " screening "; In existing seawater and brackish water desalination, reverse osmosis method is the most energy-conservation.The characteristics of reverse osmosis membrane separation are that its " spectrum " is separated, be that it not only can remove various ions in the water, and can remove the particulate bigger than ion, as most organism, colloid, virus, bacterium, suspended substance etc., so the reverse osmosis isolation method has the title of wide spectrum partition method again.Revers osmosis method for desalination not only is suitable for sea water desaltination, also is suitable for brackish water desalination.In the existing desalination process, the bitter degree of saltinessization of reverse osmosis is most economical.
Desalination technology is said technically through the development of over half a century, has become to heat, on a large scale desalinating sea water into fresh water, and industrialization.Method for desalting seawater has three major types: evaporation, freezing, reverse osmosis.Evaporation, freezingly all must pass through phase transformation, energy consumption is very big, is extremely uneconomic.Reverse osmosis is physical change, has operability; Development in recent years is rapid, and engineering is used also more, becomes the dominant technology of sea water desaltination just day by day.
The key of reverse osmosis seawater desalting technology is a reverse osmosis membrane.Though the production of film and assembly is quite ripe, the ratio of desalinization of film＞99.3%, the mean life of film is shorter, costs an arm and a leg, and this is to cause sea water desaltination to be processed into a higher major reason of wood; And the film pollution is to cause film short major cause in work-ing life.It is decelerating membrane pollution, the duration of service that prolongs film that seawater is carried out pre-treatment, guarantees the key of reverse osmosis system operation steady in a long-term.By pre-treatment is to remove suspended substance, organism, colloidalmaterial, microorganism, bacterium and some objectionable impurities (as iron, manganese, calcium etc.).The table that accumulates in film because of the suspended substance in the water, colloidalmaterial and soluble organic macromolecule can make film be polluted; Microorganism and bacterium can make film suffer erosion; The residual body of microorganism and bacterium also can be separated out with solid form, and film properties is degenerated; The deterioration of the temperature of water, pH value, contents of residual chlorine, pressure and other parameters can cause hydrolysis, the oxidation of film; The membrane structure that is caused by solute changes the permeability rate decline that also can cause film.
It is more complicated that the reverse osmosis membrane sea water desaltination is carried out pretreated technology to seawater.In view of above situation, innovate a kind of new technology and new installation of reverse osmosis, will become a higher innovation problem.
The present invention---device for desalination treating sea water with fibre cloth block is exactly research under such background, explores and a kind of new technique pattern of formation.
