Description
Technical field
The present invention relates to a kind of energy-saving seawater treating plant, belong to water-treatment technology field.
Background technology
Seawater is flowing, and for the mankind, water volume that can be utilized is unrestricted.Seawater is liquid mineral reserve worthy of the name, and on average have the mineral substance of 3,570 ten thousand tons in the seawater of every cubic kilometer, in 100 known in the world multiple elements, 80% can find in the seawater.The source of seawater or land fresh water and the setter of weather, the fresh water that world ocean evaporates every year has 4,500,000 cubic kilometers, wherein 90% returns to ocean by rainfall, and 10% becomes sleet drops on large ground, then returns to ocean again along river.Desalination technology develops into industry.It was expected, along with the deterioration of ecotope, the last approach that the mankind solve water shortage is likely the desalination to seawater.
Seawater is a kind of very complicated polycomponent aqueous solution.In seawater, various element all exists with certain physical chemistry form.The existence form of copper is comparatively complicated in the seawater, and major part is that organic complex form exists.In free ion, only have sub-fraction to there is major part with bivalent positive ion form is all occur with negative ion complex compound.So free copper ion only accounts for the sub-fraction of whole dissolved copper.Have the sodium that content very enriches in seawater, but its chemical conduct is very simple, it almost all exists with Na+ ionic species.
Containing a large amount of salt and multiple element in seawater, wherein many elements are that needed by human body is wanted.But various material concentration is too high in seawater, considerably beyond sanitary standard for drinking water, if drunk in a large number, can cause that some element is excessive enters human body, affect the physiological function of human normal, human body also can be caused to dewater, serious also causing is poisoning.
Shortage of fresh water in the world, a lot of country is in the state of serious water shortage, in order to production, the life of the mankind, by sea water desaltination, purification, for the mankind, provides existence water source, is the needs of human survival.And when people go to sea, after the fresh water on ship is used up, people will be in the predicament not having fresh water supply and demand, the excessive lack of water of people will produce life danger, and seawater can not directly be drunk, and just can drink after needing purification, desalination.Sea water desaltination is mainly in order to supply drinking water and agricultural water, and edible salt also can be produced as byproduct sometimes.Sea water desaltination is very popular in Middle East, and some island and ship are also used.Therefore seawater cleaning desalination techniques is more and more extensive in the application of society.Because tellurian sewage, waste residue, waste oil and chemical substance constantly flow into the sea in a steady stream, also purifying treatment to be carried out to seawater to before sea water desaltination.
A large amount of microorganism, bacterium and algae is there is in seawater.In seawater, the breeding of bacterium, algae and microbial growth not only can bring many troubles to water intake facilities, and directly can affect the normal operation of sea water desalting equipment and process pipe.Periodically flood tide, ebb, carry a large amount of silt in seawater secretly, turbidity changes greatly, and easily causes seawater pretreatment system to operate unstable.Seawater has larger corrodibility, will do certain screening to the material of the equipment adopted in system, valve, pipeline member, and corrosion resistant performance will be got well.
Sea water desaltination treatment technology refers to the sea water desaltination of 35000mg/L to the tap water of below 500mg/L.At present, the beautiful sea water desaltination membrane method in east applied of installing in the world mainly contains multistage flash evaporation (MSF), multiple-effect evaporation (MED) and reverse osmosis method (RO), since half a century, oneself has supported the population in the world more than 100,000,000, facilitates Arid desert region and developed country's coastal economy and social development.
Seawater is very high due to its saltiness, and can not be used directly, and mainly adopts two kinds of methods to desalinize seawater, i.e. distillation method and reverse osmosis method.The place that distillation method is mainly used in super-huge sea water desaltination process and heat energy is abundant.Reverse osmosis membrane applicable surface very wide, and ratio of desalinization is very high, is therefore widely used.First reverse osmosis membrane is extracted by seawater, carry out preliminary treatment, reduce turbidity of sea water, prevent the microbial growth such as bacterium, algae, then the supercharging of Special high-voltage pump is used, make seawater enter reverse osmosis membrane, because seawater saltiness is high, therefore seawater reverse osmosis membrane must have equipment with high desalinization, the features such as corrosion-resistant, high pressure resistant, antipollution, seawater after reverse osmosis membrane processing, its saltiness reduces greatly, about TDS content is down to 200 mg/litre from 36000 mg/litre.Water quality after desalination is even better than tap water, so just can for industry, business, resident and boats and ships, naval vessels.
Current Global Seawater desalination techniques is planted more than more than 20, comprise reverse osmosis method, low multiple-effect, multistage flash evaporation, electroosmose process, pressure steam distillation, dew point method of evaporation, water-electricity cogeneration, hotting mask coproduction and utilize nuclear energy, sun power, wind energy, tidal energy seawater desalination technology etc., and multinomial pre-treatment and the aftertreatment technology such as micro-filtration, ultrafiltration, nanofiltration.
From large classification, be mainly divided into distillation method (hot method) and the large class of embrane method two, wherein low multiple-effect distillation, multistage flash vaporization and reverse osmosis membrane are global mainstream technologys.Generally speaking, low multiple-effect has energy-conservation, low, the desalination water quality advantages of higher of sea water preprocessing requirement; Reverse osmosis membrane has low, the low power consumption and other advantages of investment, but sea water preprocessing requires high; Multistage flash vaporization possesses skills ripe, reliable, the advantage such as device output is large, but energy consumption is higher.It is generally acknowledged, low multiple-effect distillation and reverse osmosis membrane are future directions.
