Description
Technical field
The present invention relates to sewage treatment area, particularly relate to a kind of electro-adsorption demineralization regeneration system rapidly and renovation process.
Background technology
Along with development economic and society, the human on the one hand demand and the requirement of quality to water is more and more higher, and on the other hand, scope and degree that water pollutes are also increasing.
The electro-adsorption demineralization technology is as a kind of water technology, and its total technical process is divided into 3 parts, and workflow, short circuit leave standstill flow process, short circuit regeneration flow process.Workflow is to make electrode of opposite sheet logical positive negative electricity in position in the module, utilizes the potential difference between the electrode slice to adsorb the interior zwitterion of former water, reaches the purpose that purifies former water, and at this moment, the pH value is lower near the anodal electrode slice, shows acid; The pH value is higher near the electrode slice of negative pole, shows alkalescence.The water outlet of electro-adsorption module promptly is the product water of electro-adsorption demineralization system in this process; It is with electrode slice positive and negative electrode short circuit that short circuit leaves standstill flow process, because the electromotive force of absorption zwitterion disappears, zwitterion meeting desorption is in module channels; Short circuit regeneration flow process is that water is gone out the electro-adsorption module with desorption in the short circuit process to the whole ions in the passage, makes it to obtain regeneration.
Use existing electro-adsorption system process, find through secular actual motion, significantly decrease, trace it to its cause with the desalination rate that begins to compare the electro-adsorption module, along with electrode lengthening duration of service, the surface has produced the acidic-group that has ion-exchange in a large number.This kind group has the function of similar ion-exchange, that is: electrode slice is placed the lower solution of pH value, the positively charged ion generation permutoid reaction of hydrogen ion energy and the absorption of electrode surface group in the solution, hydrogen ion is adsorbed by electrode slice, and the cation concn of bulk solution raises; Again electrode slice is inserted the pH value in the neutral salts solution, the hydrogen ion of electrode surface group absorption again can with the positively charged ion generation permutoid reaction in the solution, positively charged ion is adsorbed by the electrode slice group, the pH value reduction of solution.This behavior shows in the module routine, during work, shows acid because electrode slice is anodal that is:, the pH value is lower, and the positively charged ion that adsorbs on the electrode slice group can be exchanged in the original solution by hydrogen ion, and the cation concn of original solution is raise, go out water concentration and raise, influence clearance.And in regenerative process, solution is neutral near the electrode slice, and the positively charged ion in the solution can come back on the electrode slice positively charged ion by the exchange of the hydrogen ion on the electrode slice group, influences regeneration effect.Formed the process of adsorbing---desorption---absorption contrary with the electro-adsorption module.Cause electro-adsorption module adsorption efficiency to descend.
