This invention discloses a purification process in late seawater desalting treatment. The process comprises: adding primarily desalted seawater into a natural mineral ion exchange device, mixing with natural mineral ion exchanger for ion exchange, transporting into a natural mineral purification and filtration device for purification and filtration, sterilizing in an ultraviolet sterilizer, and canning. The process has such advantages as easy operation, low cost, and no pollution, and is suitable for purification of seawater in late seawater desalting treatment, and purification of brackish water in China northwestern regions in late seawater desalting treatment.
Description
Technical field:
The present invention relates to sea water desaltination, be specifically related to a kind of sea water desalination later purification treatment process.
Background technology:
Though the tellurian water yield is very big, 97% is seawater, and fresh water only accounts for 3%, and skewness, the some places Freshwater resources very lack, and especially lack the island and the landlocked arid area of tap water for some, and fresh water has become the major issue of people, animal existence.Investigation shows that coastal and landlocked underground brackish water is China second potential water source, and this water of long-term drinking can cause people, animal osteoporosis, tooth blackspot, but serious also cause cancer.
Along with rapid development of modern science and technology, people more and more pay attention to the development and use of seawater fresh water and underground brackish water.Through constantly exploring, the method for sea water desaltination has: distillation method, subzero fractionation method, reverse osmosis method, electroosmose process, pressure are oozed method, hydrate and solvent extration etc., and what use the most extensively at present is distillation method and reverse osmosis method.
Distillation method is that the seawater heating is made it explosive evaporatoin, becomes vapor condensation the process of fresh water to be distillation method again.Desalination effect behind the single flash is bad, still contains salts substances such as a spot of sodium-chlor, Repone K, sodium sulfate and yellow soda ash in the aqueous solution after its desalination, and mouthfeel is relatively poor, need repeatedly distill, and consumes more energy.Distillation method has methods such as vertical tube distillation, multistage flash evaporation, multistage single flash, vapour compression distillation and solar distilling.Report according to pertinent data: drink distilled water for a long time, found that the small white mouse growth is slower, weight loss, osteoporosis, amyotrophy, pituitary gland and kidney glandular system function are destroyed.
Reverse osmosis method is to adopt a kind of membrane sepn desalination process, force seawater to pass through fine and closely woven film, under pressurized conditions, film only allows water pass through, and materials such as salt are refused outside film, reverse osmosis method is that molecules of salt is separated from seawater, what obtain is pure water, the original mineral substance to the human body beneficial that exists in the water has also been filtered, lack necessary mineral substance of human body and trace elements such as calcium, magnesium, iron, strontium, zinc, fluorine, iodine, selenium in the pure water, the long-term drinking pure water can reduce the absorption of beneficial element, is unfavorable for HUMAN HEALTH.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, a kind of sea water desalination later purification treatment process is provided.
The sea water desalination later purification treatment process is: the seawater after at first will tentatively desalinating joins in the ion exchange unit of natural mineral for seawater desalination and carries out ion-exchange with ion exchanger of natural mineral for seawater desalination, be transported to then in the filtration equipment for clarifying of natural mineral for seawater desalination and carry out purification filtering with purified filtering agent for seawater desalination by using natural mineral, re-use the ultraviolet radiation for sterilizing and disinfecting device and carry out disinfection, canned is finished product.
Seawater after the preliminary desalination is meant the aqueous solution that obtains after seawater is through methods such as distillation method, subzero fractionation method or reverse osmosis methodes.
Ion exchanger of natural mineral for seawater desalination is made up of montmorillonite, attapulgite, zeolite, medical stone and sepiolite.The preparation method of ion exchanger of natural mineral for seawater desalination is: batching is soaked, pushes airing, abrasive dust, is packaged as finished product; Purified filtering agent for seawater desalination by using natural mineral is made up of attapulgite, montmorillonite, zeolite, diatomite, medical stone and sepiolite; The preparation method of purified filtering agent for seawater desalination by using natural mineral is: batching is soaked, is pushed airing, crushing and screening, roasting cooling, is packaged as finished product; The ultraviolet radiation for sterilizing and disinfecting device is the conventional products of market supply.Ion exchanger of natural mineral for seawater desalination and purified filtering agent for seawater desalination by using natural mineral separate case application patent of invention.
Ion exchanger of natural mineral for seawater desalination in the ion exchange unit of natural mineral for seawater desalination not only can effectively carry out ion-exchange with sodium and the potassium ion in the seawater, can also reach the purpose of ion exchanger of natural mineral for seawater desalination being carried out modification, indexs such as the blue amount of colloid index, expansion capacity, suction of the sea-changed back of process ion exchanger of natural mineral for seawater desalination, cation exchange capacity, all improved largely, can be used to produce the higher byproduct of class, realize the waste zero release.
In the filtration equipment for clarifying of natural mineral for seawater desalination purified filtering agent for seawater desalination by using natural mineral, granule interior has a large amount of micropores, better than the long-pending hard intensity of table, the purification filtering effect is remarkable.Purified filtering agent for seawater desalination by using natural mineral can further reduce the content of salts substances such as sodium-chlor in the seawater, Repone K, sodium sulfate and yellow soda ash, heavy metal and objectionable impuritiess such as muriate and residues of banned pesticides such as mercury, lead, arsenic in the purifying filtered water.
The present invention is achieved by following technical proposals:
1, the seawater after the preliminary desalination enters in the settling chamber from the water inlet pipe of ion exchange unit of natural mineral for seawater desalination and mixes with ion exchanger of natural mineral for seawater desalination, sodium in the seawater and potassium ion and ion exchanger of natural mineral for seawater desalination carry out ion-exchange, discharge from rising pipe through the aqueous solution after the precipitation clarification, overflow pipe is capacity and the discharged air that is used for observing the aqueous solution in the ion exchange unit of natural mineral for seawater desalination, and upper cover plate is used for placing and the cleaning ion exchanger of natural mineral for seawater desalination.
