Problems solved by technology

However, the protection of the filter membrane is not enough. Some organic matter is adsorbed on the filter membrane and cannot be decomposed, causing the membrane to fail. Activated carbon is easily contaminated by bacteria and becomes saturated and fails, and even becomes a breeding ground for bacteria to further block the filter membrane, etc.
The pre-treatment is unqualified, so that the reverse osmosis membrane or ultrafiltration membrane is seriously polluted and damaged.
The post-electrochemical treatment process will also bring many new problems, such as cathode reduction will generate nitrite, heavy metal ions cannot be filtered out, resulting in excessive heavy metals, etc., which will eventually lead to substandard water purifiers

Embodiment 1

[0034] The pure water machine of the present embodiment is as figure 1 As shown, it includes an electrolysis unit and a membrane filtration unit 9; the electrolysis unit includes a pair of yin and yang electrodes, an electrolysis power supply (not shown in the figure) and a water tank 1 for powering the yin and yang electrodes, and a pair of negative electrodes 3-1 and positive electrodes 3 -2 is provided with a water-permeable diaphragm 5-1 made of non-conductive material; the water tank 1 is provided with a first water inlet 1-1 and a first water outlet 1-2, and a window is opened on the side wall of the water tank 1, The water permeable diaphragm 5-1 is fully laid on the window, the cathode electrode 3-1 is located inside the water tank 1 and the anode electrode 3-2 is located outside the water tank 1; the water tank 1 is provided with a porous adsorption material 30, and the first water outlet 1- 2 is located at the center of the block of porous adsorption material 30; the...

Embodiment 2

[0056] This embodiment is an improvement on the basis of Embodiment 1, and the difference from Embodiment 1 is that: figure 2 As shown, the outer side of the water tank 1 is provided with a housing 20 surrounding the lower part of the water tank 1, and a closed space is formed between the housing 20, the water tank 1 and the water-permeable diaphragm 5-1, and the positive electrode 3-2 is located in the closed space. 20 is provided with an opening 20-1, and the opening 20-1 forms the water inlet 1-1 of the water tank 1; the bottom of the housing 1 is provided with a first sewage outlet 20-2. Municipal tap water is injected into the closed space from the water inlet 1-1, and enters the water tank 1 through the water-permeable diaphragm 5-1 arranged between the housing 20 and the water tank 1 under the pressure of tap water.

[0057] In order to improve the water inlet efficiency, a booster pump can be arranged between the water inlet of the water tank 1 and the municipal water...

Abstract

The invention relates to a water purifier.The water purifier comprises an electrolysis unit and a membrane filtration unit.The electrolysis unit comprises at least one pair of anodic electrode and cathodic electrode, an electrolysis power source supplying power to the anodic electrodes and the cathodic electrodes and a water tank.A permeable diaphragm made of a non-conductive material is arranged between the anodic electrode and the cathodic electrode in each pair.The water tank is provided with a first water inlet and a first water outlet.Each permeable diaphragm is provided with permeable micropores with a uniform aperture.The side wall of the water tank is provided with windows.The permeable diaphragms are fully laid on the windows.The cathodic electrodes are arranged in the water tank, and the anodic electrodes are arranged outside the water tank.A porous adsorbing material is arranged in the water tank.The first water outlet is formed in the porous adsorbing material.The membrane filtration unit is provided with a second water inlet and a second water outlet.The first water outlet is communicated with the second water inlet.Compared with an existing physical filtration water purifier, the water purifier is reliable in operation and long in service life.

Description

technical field [0001] The invention relates to a pure water machine, 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 and abroad st...
