Description

Direct drinking water treatment device for urban communities

technical field

The utility model relates to a device, in particular to a direct drinking water processing device for urban communities. Centralized supply of drinking water.

Background technique

Direct drinking water means that it is directly purified at the user terminal, activated and energyized, treated by a purification system that simulates natural water, and directly outputs direct drinking water that meets national standards. At present, the direct drinking water treatment terminals on the market generally use activated carbon adsorption, ultrafiltration, reverse osmosis filtration and electrochemical purification.

In the early stage of activated carbon adsorption treatment, due to the strong adsorption capacity of activated carbon, the purified water quality is better; but when the activated carbon adsorption capacity is reached, the activated carbon must be replaced or regenerated, otherwise the adsorbed impurities will be reversed, and the quality of the effluent water will be worse than that of the influent water. The adsorption capacity of activated carbon is generally related to the amount of treated water and the quality of influent water. It is difficult to judge the best time to replace activated carbon in the process of ordinary household use. Due to the long water supply pipeline and the long history of the pipeline, bacteria in the water are easy to breed, and the adsorption method of activated carbon to treat direct drinking water does not have the ability to sterilize bacteria. Therefore, there are many safety hazards in drinking water that has only been treated by activated carbon adsorption.

The principle of ultrafiltration and reverse osmosis filtration is to use the selective permeability of the membrane, only water and very small harmless ions can pass through, and the rest of the impurities are intercepted, so as to achieve the purpose of water purification; the membrane separation method is more effective, but the membrane There is a lifespan problem, and it must be cleaned or replaced regularly, and the operation is more complicated; the ultrafiltration method cannot remove calcium and magnesium ions in the water; the reverse osmosis filtration will also produce 1:1-1:3 wastewater during the treatment process, and the raw water utilization rate Not high, and the purified water is too pure and lacks trace elements beneficial to the human body.

Electrochemical treatment is mainly the electrolysis method. The electrolysis method is that the tap water passes through the positive and negative electrodes, and under the action of the electric field energy, the water molecular clusters are broken up, reduced, and rearranged, so that some of the water has a positive potential, and the other part of the water has a positive potential. Negative potential, and finally through membrane separation technology to obtain positive electrolyzed water and negatively electrolyzed water; positively electrolyzed water, with positive potential, acidic, high oxygen content, astringent and bleaching; negatively electrolyzed water with negative potential, molecular clusters It is small, slightly alkaline, and sweet in taste. It is an excellent healthy drinking water, which has the functions of anti-fatigue, anti-oxidation, increasing SOD (superoxide dismutase) activity, and regulating blood lipids. However, the pre-processing requires filtration, and the post-processing requires membrane separation, and the positively electrolyzed water is wastewater. It can be seen that the electrochemical treatment is not economical and efficient, and there is trouble of regular replacement of electrode plates.

Therefore, to solve the existing deficiencies in the existing water treatment, it is particularly necessary to provide a direct drinking water treatment device that is efficient, convenient, low in operating costs, and sterilizable.

The publication date is November 19, 2014, and the Chinese patent with the publication number 104150662A discloses an invention patent named "direct drinking water system and process". The patent includes an ultrafiltration device, an activated carbon filter device, a reverse osmosis device and a circulation pipe network connected sequentially through a delivery pipeline. Raw water is filtered by ultrafiltration device, activated carbon filter device, and reverse osmosis device, and then the treated direct drinking water is transported to each point of use through the circulation pipe network for circular supply. Although this patent can be applied to purify various raw water into direct drinking water, the utilization rate of raw water is not high due to ultrafiltration and reverse osmosis filtration, and the purified water is too pure and lacks trace elements beneficial to the human body, so it still exists the aforementioned deficiencies.
