Embodiment 1

[0061] The tea-making device of the present embodiment that can degrade residual pesticides, see figure 1 , including a pair of cathode electrodes 22 and anode electrodes 23, an electrolysis power supply and an insulating frame 25 for supplying power to the cathode and anode electrodes. A water-permeable diaphragm 21 is provided between the cathode and anode electrodes.

[0062]Both the cathode electrode 22 and the anode electrode 23 are cylindrical electrodes fixed on the insulating frame 25. The cathode electrode 22 is formed with a mesh, and a separator is arranged inside the cathode electrode 22, and the interior of the cylindrical cathode electrode is divided into an upper cavity by the separator. Chamber 13 and lower chamber 14 for placing tea leaves. The positive electrode 23 is disposed in the upper chamber 13 . The water-permeable diaphragm 21 is fully covered on the outer surface of the anode electrode 23 . When in use, the negative electrode 22 is immersed in the...

Embodiment 2

[0084] The tea making device of this embodiment that can degrade residual pesticides is an improvement on the basis of Embodiment 1, and the difference from Embodiment 1 is:

[0085] In this embodiment, the kettle body is manually filled with tap water. Still taking the city supply tap water in Dalian, China as an example, the electrolytic power supply adopts an alternating pulse power supply with a forward voltage level greater than a reverse voltage level. The average voltage is 15V, and the water is permeable. The positive diaphragm 21 adopts a microfiltration membrane, and the distance δ between the microfiltration membrane and the anode electrode 23 located outside the membrane is 15 millimeters.

Embodiment 3

[0087] The tea-making device of this embodiment that can degrade residual pesticides is an improvement on the basis of Embodiment 1. The difference from Embodiment 1 is that in this embodiment, there are several holes on the positive electrode 23 located on the outside of the water-permeable diaphragm 21. Through holes, the water-permeable diaphragm 21 adopts a nanofiltration membrane.

[0088] In this embodiment, the municipal tap water in Dalian, China is still taken as an example, and the distance δ between the water-permeable diaphragm 21 and the anode electrode 23 located outside the diaphragm is 0 mm and 10 mm, respectively.

Abstract

The invention relates to a tea making device capable of degrading residual pesticide and belongs to the technical field of deep treatment of domestic drinking water. The tea making device comprises a pair of negative and positive electrodes, an electrolysis power supply for supplying power to the negative and positive electrodes and an insulation frame, wherein a water permeable diaphragm is arranged between the negative and positive electrodes, the negative and positive electrodes are respectively a tubular electrode fixed on the insulation frame, meshes are formed in the negative electrode, a separating plate is arranged in the negative electrode and divides the interior of the tubular negative electrode into an upper chamber and a lower chamber used for containing tea leaves, the positive electrode is arranged in the upper chamber, the water permeable diaphragm completely covers, lays on and coats the outer surface of the positive electrode, when the tea making device is used, the negative electrode is immersed into tea making water, and the positive electrode only contacts the tea making water by virtue of water permeating the water permeable diaphragm. The tea making device has the advantage of safely and efficiently degrading and removing pesticide residue in tea water.

Description

technical field [0001] The invention relates to a tea making device capable of degrading residual pesticides, and belongs to the technical field of advanced treatment of drinking water quality. Background technique [0002] 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". At present, the deterioration of the water environment has seriously endangered the continuation of life, especially when natural disasters and man-made disasters suddenly occur...
