Technical field
The invention belongs to Water warfare fields, are related to the processing of micro- pollution bitter, and in particular to a kind of micro- dirt in processing rural area
It contaminates the device of the Electro Sorb coupling extension activated carbon of bitter, and salt and organic is removed in micro- pollution bitter using the device
The method of object.
Background technology
With the continuous social and economic development and the sustainable growth of the size of population, industrial production and life are drunk required light
Water resource is increasingly deficient, especially NW China Arid&semi-arid area, and serious water shortage problem directly restricts local society
Economic sustainable development, therefore, the utilization of the bitter widely distributed to the Northwest is increasingly valued by people.It is bitter
Salt water has the outstanding problems such as high salinity, high rigidity, and harmful effect can be caused to body by drinking bitter for a long time.And it is traditional
Technique of desalinating saline water, such as thermal distillation and reverse osmosis two methods, thermal distillation concentrates distillation after boiling seawater, and reverse osmosis
Technology is then concentrated seawater and by filter membrane desalination under high pressure, is required for consuming a large amount of fossil energies and electricity, while not
The evitable part that eliminates is beneficial to the trace element of health.Moreover, most of fresh water area in short supply is all the energy
The opposite remote districts lacked of resource, the acquisition of freshwater resources cannot be to consume the non-renewable energy as cost.
Micro-polluted water refers to the physics, chemistry and microbiological indicator of water cannot reach《Environmental Quality Standard of Surface Water》
The middle water quality requirement as drinking water sources water, water pollutant one-way metrics, as turbidity, coloration, stink, sulfide,
Poisonous and harmful substance, pathogenic microorganism etc. have exceeded phenomenon, but are the water source by organic matter micropollution in most cases.It is existing
Conventional treatment process cannot effectively remove dissolved organic matter and part ion, while membrane technology can remove part to human body
The longevity is used and there is the film caused by concentration polarization and fouling membrane in the trace elements such as healthy and beneficial iron, zinc, secondly, membrane technology
Life shorten, permeation flux extends at any time and decline and operating process energy consumption increase the problems such as.
Electro-adsorption demineralization technology is a kind of technology for removing water removal intermediate ion of environment-friendly type, it is electrochemical theory and electric double layer
Both theoretical product combined.The desalting process of Electro Sorb technology is not related to the gain and loss of electronics, and required electric current is only used for suction
The electric double layer at attached solution electrode interface charges, thus is a low power consumption process.The desalination technology belongs to atmospheric operation, has work
Skill equipment is simple, and low energy consumption, at low cost, and its regenerative process is without the advantages of adding medicament, not generating secondary pollution.
Activated carbon has stronger absorption property as a kind of environmentally friendly adsorbent, and raw material is sufficient and safe,
The advantages that acid and alkali-resistance, heat-resisting, not soluble in water and organic solvent, easy regeneration, to the organic pollution such as benzene class chemical combination dissolved in water
Object, phenolic compound etc. have a stronger adsorption capacity, while to coloration, herbicide, insecticide, synthetic dyestuffs and many artificial
The organic compound of synthesis also has preferable removal effect；It is widely used in the various fields such as food, chemical industry, still, with warp
The consumption of the development of Ji, activated carbon is also huge, if do not recycled, it will and it generates the wasting of resources and generates secondary pollution,
It is imperative for the regeneration of activated carbon.
The regeneration of activated carbon has following several method：Hot recycling, wet air regeneration, microwave radiation regeneration and electrochemistry are again
It is raw.Wherein, hot recycling is mainly heat-treated carbon leaching material by heating, makes the organic matter of activated carbon adsorption in high temperature
Lower charcoal solution becomes gas effusion, and finally so that activated carbon is regenerated, the method efficiency is higher, and the recovery time is short, application range
Extensively, but every time the loss of regenerated carbon is generally all between 5%-10%, and the mechanical strength of regenerated carbon declines, and adsorption efficiency is also dropped
Low, investment is big, costly, is not easy to minimize.The stabilised efficiency of wet air regeneration, quickly, low energy consumption, but efficiency is only 50%
Left and right, regeneration equipment requirement is relatively high, and the exhaust gas of generation needs are further processed, and inconvenient for operation, operation and maintenance cost compared with
It is high.Microwave radiation regeneration is carried out in closed container, compactness and high temperature resistant, corrosion resistance requirement to device
Stringent, while the substance evaporated cannot exclude in time, when the leakage energy power of microwave was more than for 0.01 time up to 6 or more, to people
Body is harmful.And electrochemical regeneration technology is to fill activated carbon between the anode and cathode, using sodium chloride solution etc. as electrolysis
Liquid is passed through direct current, by the strong oxidizers oxygenolysis adsorbate such as electrolysate such as chlorine, hypochlorous acid, hydroxyl radical free radical.It should
The advantages of technology is regeneration efficiency height（80%~95%）, repeatedly regeneration efficiency declines unobvious after regeneration, and does not generate secondary dirt
Dye.
Known to research situation based on current water treatment desalination technology：The desalination for improving water removes organic matter rate, reduces water
It handles energy consumption and ensures that device purification is most important with the environmental-friendly development for water technology of regenerative process.
Invention content
The present invention is big for energy consumption of the existing technology, generate secondary pollution, desalination is except organic matter efficiency is low and active
The problems such as charcoal regeneration effect is poor, provide it is a kind of have efficient desalination except organics function, be easy to regeneration and environmental-friendly electricity
