Basic working principle of electrodialyzer in CangzhouWith the increasing demand for factory drainage in China, electrodialyzer has become a way of factory sewage treatment. Electrodialysis water treatment process is the raw water (tap water) through the activated carbon filter tank and wire wound filter tank into the electrodialyzer, electrodialyzer electrochemical treatment is divided into three ways: all the way to the pole water, direct discharge; all the way to fresh water, through the reversing solenoid valve into the fresh water storage tank to further carry out ion exchange, made of higher purity of pure water; there is also a way of concentrated water, is a high concentration of ions in the wastewater, to be after reversing the solenoid valve to discharge to the outside of the machine. Solenoid valve to be discharged to the outside of the machine. From the electrodialyzer outflow of three kinds of water, fresh water accounted for about 45-50%, concentrated water accounted for about 40-50%, polar water accounted for about 10-15%. Electrodialyzer can not only be used as a pretreatment device for ion exchange to reduce the burden of the later stage and improve the purity of water, but also can be used alone to soften the water quality and supply boiler water, and can be used for desalination of saline and alkaline belt water, improving the quality of beverages, wastewater treatment, recycling of useful metals, and health care. The concentrated water channel and fresh water channel at the output of electrodialyzer are not fixed, because the concentrated water channel will accumulate a large number of salts and impurities precipitation for a long time, resulting in clogging, and the quality of fresh water is not guaranteed. Therefore, the concentrated water channel and fresh water channel should be replaced frequently, but not too frequently, so as not to mix the concentrated water into the fresh water storage bucket. Generally every shift (8h) for a change of direction is appropriate. Cangzhou Li Jia Water Treatment Equipment Co., Ltd. is a professional enterprise of reverse osmosis equipment, electrodialysis equipment and electrodialysis device. Electrodialysis device is based on the principle of electrodialysis designed and applied to water treatment, membrane separation and filtration design, research and development, manufacturing and processing, as well as engineering contracting, installation and commissioning. Brine high temperature electrodialysis desalination method, including the following steps: high temperature desalination of brine, through the centrifugal pump pumped into the ultrafiltration pre-treatment device, the pre-treated brine through the centrifugal pump pumped into the jacketed electric heating tank, heated to 60-80 ° C, and then the pre-treated brine into the adsorption tank equipped with molecular sieve, static for 4-6 hours, and then desalinated brine will be sent to the jacketed electric heating tank, heated to 60-80 Then the desalinated brine is sent into the concentration chamber of electrodialysis device through centrifugal pump, and 0.05-0.5 is added into the concentration chamber. Na2SO4 solution with concentration of 0.2-0.3 mol/L is prepared in electrodialysis device, and the Na2SO4 solution is pumped into the pole chamber of electrodialysis device by centrifugal pump until the conductivity of the water produced in the outlet of the desalination chamber of electrodialysis device is reduced to 500-800μs/cm, and then it is pumped into fresh water. /cm, and then pumped into the fresh water tank. The present invention effectively desalinates high-temperature brine by combining high-temperature electrodialysis with ultrafiltration pretreatment, thereby increasing the limiting current of electrodialysis, reducing polarization precipitation, and extending the operating cycle of the electrodialysis unit. Electrodialysis was used to remove inorganic salts (potassium sulfate) from simulated biodiesel wastewater. The influence of electrodialysis process factors on the desalination effect was investigated, and the effect of glycerol on the electrodialysis desalination process was discussed.
