Simple table type water dispenser

Abstract

The invention relates to a simple table type water dispenser. The simple table type water dispenser comprises an electrolysis unit and a membrane filtering unit, wherein the electrolysis unit comprises two pair of paired negative and positive electrodes, an electrolysis power supply and a water tank, wherein a first water inlet and a second water outlet are formed in the water tank; the two pair of the paired negative and positive electrodes include a first electrode pair and a second electrode pair, a first water-permeability diaphragm prepared from non-conductive materials is arranged between negative and positive electrodes of the first electrode pair, a second water-permeability diaphragm prepared from non-conductive materials is arranged between negative and positive electrodes of the second electrode pair, the positive electrode of the first electrode pair and the water tank are separated by the first water-permeability diaphragm, the negative electrode of the second electrode pair and the water tank are separated by the second water-permeability diaphragm, and the negative electrode of the first electrode pair and the positive electrode of the second electrode pair are located in the water tank; and the membrane filtering unit is provided with a second water inlet and a second water outlet which are communicated to each other. According to the simple table type water dispenser, the pollutants in source water can be efficiently removed, and bacteria in source water can be thoroughly inactivated.

Description

technical field [0001] The invention relates to a simple desktop water dispenser, which belongs to the technical field of drinking water terminal water quality treatment. Background technique [0002] At present, the water environment is deteriorating, and drinking water quality and safety accidents occur frequently, which has seriously endangered human survival. Water pollution is mainly caused by pollutants produced by human activities, including industrial pollution sources, agricultural pollution sources and domestic pollution sources. Increasing water pollution has posed a major threat to human survival and has become a major obstacle to human health, economic and social sustainable development. According to the investigation of the authoritative organization in the world, at least 20 million people in the world die every year due to drinking unsanitary water. Therefore, water pollution is called "the number one killer in the world". [0003] Most waterworks at home a...

Problems solved by technology

The common deficiencies of these technologies are that firstly, the overall design of the system is not considered, and only local single measures often make the overall work of the system unbalanced; secondly, they do not consider starting from improving the water inlet conditions of the membrane elements to reduce the workload of the membrane elements , can be said to be "a temporary solution but not a permanent cure", so no real practical and commercial products have come out so far

[0005] In contrast, although the chemical water treatment process has many advantages such as cheap, simple and efficient, it is an excellent advanced oxidation process, but there are a series of problems in the electrochemical treatment itself, and it is not suitable to be used alone in the treatment of drinking water in civilian terminals. It has not been widely used in daily water treatment occasions

The reason is that the chemical water treatment process needs sufficient reaction time, but in the daily water situation, the water purifier is only a few seconds from the start-up to the water discharge, and the residence time of the pollutants in the water purifier is too short to complete the relevant process. Chemical reaction treatment; secondly, the chemical water treatment process may be accompanied by certain toxic and side effects

For example, although the chemical oxidation reaction process can effectively inactivate bacteria, deeply degrade organic matter, and remove various harmful substances in water, the various strong oxidation factors generated by chemical oxidation are basically non-selective and uncontrollable. Improper use is very likely to produce new substances that are not in the source water, which will endanger the safety of drinking water; because of this, the application of chemical water treatment processes can be said to be cautious in the daily drinking water purification treatment of the public
