Problems solved by technology

[0003] 1) The pollution of the water environment is deteriorating day by day, the treatment process of the existing waterworks is outdated, and the quality of the factory water has been difficult to meet the standard (especially in the case of sudden drinking water sanitation incidents);
[0004] 2) Secondary pollution caused by the water delivery pipe network system;
[0005] 3) Residual chlorine in water interacts with residual organic matter, which may generate new harmful substances that are not in source water (such as strong carcinogen chloroform, etc.)
However, in the occasion of daily water use, the water purifier takes 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 chemical reaction treatment; the second is that the chemical water treatment process may be accompanied by certain Toxic 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

Embodiment 1

[0052] The auxiliary purification device of the water purifier of the present embodiment can be found in figure 1 (comprising the water container 1 that is provided with water inlet 9, the water inlet 9 of water container 1 is externally connected to the sewage outlet 6 of existing water purifier 7, and water purifier 7 is provided with water inlet pipe 10-1 and water outlet pipe 10-2 The housing of the water container 1 is provided with a negative electrode 2 and an anode electrode 3, and a water-permeable diaphragm 5 is arranged between the cathode electrode 2 and the anode electrode 3, and the water-permeable diaphragm 5 is close to the positive electrode 3, and the water-permeable diaphragm 5 covers On the entire surface of the positive electrode 3, the spacing δ=1mm between the water-permeable diaphragm 5 and the negative electrode 2. The water-permeable diaphragm 5 of the present embodiment adopts a single-layer PVDF ultrafiltration membrane with an average water-permeabl...

Embodiment 2

[0073] The water purifier auxiliary purification device of the present embodiment is an improvement on the basis of Embodiment 1, as figure 2 As shown, the changes from Embodiment 1 are: 1) The water container 1 is arranged at the water inlet pipe 10-1 of the water purifier 7, so that a large amount of hydrogen-based super-hydrogen is formed in the water by the water purifier auxiliary purification device. Microbubbles and strong oxidizing factors can enter the water purifier under the action of water pressure, and also play the role of sterilization and cleaning. Of course, the water container 1 can also be connected in series with the water inlet pipe 10-1 (there is a water outlet in the water container 1), and further, the water container 1 can also be connected in parallel or in series with the water outlet pipe 10-2. catch.

[0074] 2) The anode electrode 3 is changed to an inert electrode coated with platinum group oxide (coating thickness: 0.8 mm) based on titanium. ...

Embodiment 3

[0081] The water purifier auxiliary purification device of the present embodiment is an improvement on the basis of Embodiment 1, as image 3 As shown, the changes from the first embodiment are: 1) the shell of the water container 1 is made of stainless steel, and serves as the cathode electrode 2; 2) the distance δ between the water-permeable diaphragm 5 and the cathode electrode 2 is 2 mm.

[0082] The water purifier auxiliary purification device of the present embodiment is carried out water electrolysis experiment, and electrolysis time is 20 minutes, and other experimental conditions and detection method are identical with embodiment one, and experimental result is as follows table 3:
