Description
Technical field
Novel a kind of sea water desaltination desalination method and the complexes of relating to of the present invention, particularly a kind of based on solar powered and method for desalting seawater and complexes membrane sepn.
Background technology
The total reserves of water globe is 13.86 hundred million km3, and seawater just occupies 96.5%, and face of land fresh water that the mankind can take and shallow-layer fresh groundwater only are 0.79%, and inhomogeneous with region and seasonal variation distributed pole.Shortage of fresh water has become one of three overall situation problems of 21 century, and therefore, sea water desaltination and direct seawater utilization technology become the new and high technology that various countries pay much attention to, and also is one of important measures that solve China's water resources crisis.Wanting water, want resource to the sea, is that the reality that solves coastal (coastal waters) regional shortage of fresh water is selected, and also is to realize sustainable utilization of water resource, ensures the vital measure of the coastland sustainable development of socio-economy, is of great immediate significance and strategic importance.Contain a large amount of salt in the seawater.From seawater, remove salt, extract fresh water? it is the dream that the mankind have pursued the centuries.As far back as the epoch of the big navigation in the world, British royal family was just once put on someone's head and was solicited economical method for desalting seawater.Even to this day, more than the method for sea water desaltination is existing hundreds of, mainly contain distillation method, cold method, reverse osmosis method (claiming ultra-filtration method or embrane method usually again), sun power method, low-temperature multi-effect, multistage flash evaporation, electroosmose process, pressure steam distillation, circulation electric capacity absorption method, dew point method of evaporation, water power coproduction, hotting mask coproduction etc.These methods, otherwise efficient is not high, otherwise energy consumption is big, and uneconomical.Therefore, weigh from economical standard, still not fully up to expectations.Particularly along with industry and expanding economy, under the fossil energy resource situations less and less such as oil, the mankind have to seek the new energy and replace fossil energies such as oil.Wherein, inexhaustible sun power becomes important research direction.Therefore, utilize sun power to carry out sea water desaltination and become important research project.The technology of utilizing the sun to carry out sea water desaltination has many, only China just discloses 12 of applications for a patent for invention, 34 of utility application mainly contain 99112588.6,200610030484.X, 200610113412.1,02279697.5,200410050333.1,200510107740.6,200710015141.5 etc.How these disclosed technology of utilizing sun power to carry out sea water desaltination utilizes solar energy-thermal conversion evaporation of seawater to be realized the technology of desalinating if all concentrating on, and sun power is not combined with other desalination technologies, therefore, disposable input cost is bigger, and efficient is not high, and the prospect of practice is also little.Reverse osmosis method (claiming ultra-filtration method or embrane method usually again) is a development in recent years desalination technology very rapidly, its advantage is that the efficient of sea water desaltination is higher, scale can be carried out personalized design as required, throughput is big, but its weak point is also more outstanding: the one, if adopt the single-stage desalination by reverse osmosis, the boron and the bromide of product (desalination water) exceed standard, do not meet GB5749-2006 " drinking water sanitary standard ", can not be as Drinking Water, if adopt secondary or multistage desalination by reverse osmosis, product (desalination water) is though can reach GB5749-2006 " drinking water sanitary standard ", and production cost is again than higher.The 2nd, power consumption is big, and cost is higher.Therefore, sun power and reverse osmosis method combination if can be carried out sea water desaltination, not only can improve sea water desaltination efficient, and can reduce cost by a relatively large margin.Chinese patent 200720069563.1 discloses a kind of photovoltaic reverse osmosis desalination device, and it comprises solar electrical energy generation module and the light module of reverse osmosis system.In the solar electrical energy generation module, the structure of solar panels is disclosed, the structure and the technical parameter thereof of store battery also do not disclosed.During sea water preprocessing in the light module of reverse osmosis system, adopted the interpolation flocculation agent to carry out flocculation treatment, the one, increase cost, the 2nd, add new chemical substance, thereby caused the risk of secondary chemical pollution.When the osmosis filtration in the light module of reverse osmosis system prepares fresh water, the structure of reverse osmosis membrane module is not disclosed, also do not have which kind of reverse osmosis membrane material of public use, still, the fresh water of a lot of reverse osmosis membrane material preparations can not satisfy GB5749-2006 " drinking water sanitary standard ".
