Background

Because of the continuous increase of economy, the increasing use of water resources, the increasing diversification of water pollution and the huge population capacity of China, the serious uneven water resource distribution causes the serious problem of drinking water safety of people. Because the current pollution situation of most tap water sources is serious, the conventional tap water treatment cannot meet the drinking requirement, so the tap water after the conventional treatment needs to be subjected to advanced treatment, and the conventional treatment methods comprise an activated carbon and ozone catalysis process, an ion exchange resin process and the like, wherein the ion exchange resin has low treatment cost and good treatment effect, and is widely researched and applied to the tap water advanced treatment at present. The ion exchange resin has good removal effect on inorganic ions with toxic action on nitrate, sulfate, bromide ions and the like while effectively removing organic matters in the water body, and can effectively reduce disinfection byproducts and biotoxicity of the water body.

The existing regeneration method is to convey saturated resin to a regeneration system, and the system is provided with a suspension separator, so that the resin is drained from top to bottom, but the draining time is long, the regeneration efficiency is low, in addition, the channeling phenomenon is serious, the using amount of a regenerant is large, the resin is easy to bridge and is not beneficial to returning, and meanwhile, the suspension separator is easy to run off the resin to cause the loss of the resin.

Chinese patent through retrieval: a powder resin desorption regeneration reactor (application number: 2011104268701, application date: 2011, 12 and 19), in the technical scheme of the patent, a stirrer is arranged at the center of the upper part of the reactor, and the stirrer adopts a propeller blade type; although the regenerated liquid and the resin can be fully combined by the method, the resin is easy to break in the stirring process, and the reuse of the subsequent resin is influenced; in addition, the desorption liquid suction filtration pipe and the resin discharge pipe in the reactor are both arranged at the bottom of the reactor, and in the process of recycling the resin, the resin can form a bridging effect at the desorption liquid suction filtration pipe, so that the resin is difficult to discharge through the resin discharge pipe, and the recycling efficiency of the resin is reduced; if the desorption liquid suction filter tube is at the height of the reactor, the desorption liquid suction filter tube is difficult to completely suck the liquid at the bottom of the reactor, so that the resin desorption is incomplete.
