Industrial sector is made that very big contribution for China's modernization and Urbanization Progress, but with social and industrialized
Development, has been inevitably generated a large amount of industrial wastewater.Meanwhile China is also the country of a shortage of water resources, short journey
Degree even constrains the sustainable development in China to a certain extent.The situation of such shortage and a large amount of generations of industrial wastewater
Comparison is formd, higher requirement also is proposed to Industrial Wastewater Treatment and reuse.
The pollutant contained in industrial wastewater is for another angle and misplaces the resource of position, if passing through work
Industry wastewater treatment and reuse technology can detach and recycle chemical composition therein and product, and using subsequent processing, then having can
It can continue on for industrial production or other purposes, meanwhile, the reprocessing difficulty of treated waste water can also substantially reduce, and right
Reuse is very helpful, and such thinking is also highly beneficial for the zero-emission of industrial wastewater.
Crystallisation has many advantages, such as that reaction is fast, does not generate sludge, taking up an area less, and crystallization obtains the also recyclable work of high purity product
For resource circulation utilization, therefore, the engineer application of specific waste water is handled using crystallisation has become one of recent study hot spot,
Especially in the removal of phosphorus and recycling, the removal of heavy metal and recycling, fouling etc. is prevented to be with a wide range of applications.
Electromagnetism mitigation and antiscaling technology is obtaining very fast development in recent ten years, but less in practical application, this is with lacking
Few profession is designed with certain relationship.Electromagnetism scale inhibition operation main points be：Electromagnetic signal generating means is steamed to winding around
The coil sent out on device applies certain frequency and the square-wave voltage of amplitude, substantially parallel with water (flow) direction so as to generate coil inside
Alternating magnetic field, alternating magnetic field can generate the induced electric field parallel with coil winding direction inside water body, in aqueduct
Water body under the action of alternating magnetic field and electric field the physicochemical properties of inner ion and molecule certain changes, Jin Erying occurs
It rings the formation of nucleus and precipitates the growth of particle, so as to achieve the effect that scale suppression（The beautiful of Wang Jianguo, Li Yutong, Deng Li is twined

Wideband is provided（0.5kHz~50kHz）Width funtion (100V ~ 5000V) alternating current, prevents solution from being crystallized on wall and filler same
When, moreover it is possible to it is heated for solution, it is with high salt because high-frequency alternating current is connected in external coil generates the changing alternating magnetic field in direction
Solution belongs to conductor, will will appear vortex current in the inside of conductor, realizes the further heating of high level salt solution, and magnetic field hinders
Dirty principle can reduce the precipitation of crystalline particle, reduce the generation of fouling；
4）Steam is separated into supersaturated solution and secondary steaming by the steam that evaporating area 2 solution evaporation generates by gas-liquid separator 1
Vapour, the pure indirect steam isolated are discharged from top steam (vapor) outlet 1-1, and steam (vapor) outlet 1-1 is connected to vacuum pump and heat recovery
System will reuse after both vapor compression；
5）The mixing of oversaturated solution adds the nucleus that mouthful 5-2 adds from nucleus and enters crystal region 5 along downspout 5-3, ties
The volume of crystalline region is sufficiently large, and the nucleus grown up is deposited to the bottom of crystal region 5 under gravity, finally by salt discharge device 5-5
Discharge, solution are then flowed out by overflow pipe 4-1.
Experiment shows that scale removal frequency is more suitable in low-frequency range, and it is excellent to be maintained within 20 kHz, scale suppression rate 90% with
On.
