Description
Technical field
The present invention relates to water treatment field, particularly relate to a kind of electro-adsorption demineralization regeneration system rapidly and reclaiming process.
Background technology
Along with development economic and society, requiring of human on the one hand demand and the quality to water is increasingly high, and on the other hand, the scope and the degree of water pollution are also increasing.
The electro-adsorption demineralization technology is as a kind of water technology, and its total technical process is divided into 2 parts, workflow, regeneration flow process.Workflow is to make the logical positive and negative electricity of electrode of opposite in the electro-adsorption module, utilizes the electrostatic field between the electrode to adsorb the zwitterion in the former water, reaches the desalination purpose.The regeneration flow process is the positive and negative electrode short circuit with the electro-adsorption module electrodes; Because the electric field of absorption zwitterion disappears; Zwitterion meeting desorption is in module channels, and 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.Two indexs estimating the electro-adsorption module are the desalination rate and get the water rate, the shared per-cent of salt amount that desalination rate sign product water is removed for former water module, and the salt amount of removing from former water is high more, and the desalination rate is high more.Get the per-cent of water rate characterization module water production rate with respect to total processing water yield.The product water that obtains is many more for former water, and it is high more to get the water rate.The desalination rate with the water rate high more, the electro-adsorption module performance is good more.
In order to satisfy the water outlet requirement, adopt the mode of two-stage demineralization usually.During work, former water gets into module from electro-adsorption module bottom, through after the one-level electro-adsorption module that powers up from this module top output; The product water that is removed a part of salt is by the former water as secondary electro-adsorption module; Get into from secondary electro-adsorption module bottom once more and power up module, the output saltiness meets the product water of industrial design from secondary electro-adsorption module top, generally; Because secondary electro-adsorption resume module is the product water of one-level electro-adsorption module; Thereby, secondary electro-adsorption module to remove salt load less, the salt amount of secondary electro-adsorption module internal adsorption is also little than one-level electro-adsorption module; During regeneration, water is opposite when flow process is with work in module.Former water gets into this module from secondary electro-adsorption module top; Take away the salt amount that is stored in the secondary electro-adsorption module, discharge, get into one-level electro-adsorption module top once more from secondary electro-adsorption module bottom; Wash away and take away the salt amount in the one-level electro-adsorption module, discharge from one-level electro-adsorption module bottom.This kind regeneration washes the lower secondary electro-adsorption module of saltiness earlier with former water, washes the higher one-level electro-adsorption module of saltiness again.
But above-mentioned electro-adsorption technical process also has its shortcoming.At first, in powering up working process, when the work that arrives during latter stage, one-level electro-adsorption module is saturated, but secondary electro-adsorption module also has suitable loading capacity because load is less, has just stopped powering up this moment and short circuit regeneration.Secondly; In the short circuit regenerative process; What secondary electro-adsorption module was used is the former preferably water of water quality; And one-level electro-adsorption module is used is the flushing water outlet of secondary electro-adsorption module, and when one-level electro-adsorption module was good by complete flushing, the required washing water quantity of secondary electro-adsorption module had surpassed its actual required water yield.In sum, secondary electro-adsorption module reproduction ratio is more thorough, but adsorption efficiency is lower, and this is actually the waste of electro-adsorption module.
