Problems solved by technology

[0008] However, electrochemistry is still a chemical treatment process in essence. Even if the toxic and side effects are small, there is still the risk of reducing the biological indicators of water. For example, strong oxidizing chlorate and hypochlorite will be produced in water by anodic reaction. and H 2 o 2 , O 3 Carcinogens

Embodiment 1

[0035] The pretreatment device that is used for deep purification city supply tap water of the present embodiment, see figure 1 , including yin and yang paired electrodes, an electrolytic power supply 2 and a water container 1 for supplying power to the electrodes, the water container 1 is provided with a water inlet 1-1 and a water outlet 1-2, and the city supplies tap water from the water inlet 1-1 Fill the water container 1, and the water outlet 1-2 can be connected with the water inlet of the existing RO membrane reverse osmosis water filter, so as to provide pre-treatment for the RO membrane reverse osmosis water filter. Of course, it is also possible to connect other physical adsorption or membrane filter water purifiers.

[0036] There are two pairs of paired electrodes, which are respectively the first electrode pair and the second electrode pair. A first water-permeable diaphragm 5-1 is arranged between the cathode and anode electrodes 3-1 and 3-2 of the first electro...

Embodiment 2

[0062] 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 container 1 in this embodiment is provided with a housing 20 surrounding the bottom of the water container 1, the housing 20, the water container 1, the first water-permeable diaphragm 5-1 and the second water-permeable diaphragm 5 A closed space surrounding the anode 3-2 of the first electrode pair and the cathode 4-1 of the second electrode pair is formed between -2, and an opening 20-1 is provided on the housing 1, and the opening 20-1 forms a water holding The water inlet of the container 1; the bottom of the housing is provided with a sewage outlet 20-2.

[0063] When in use, the municipal tap water enters the water container 1 through the closed space through the opening 20-1 and filtered by the first and second water-permeable diaphragms 5-1 and 5-2, and the pollutants in the water are intercepted in the clo...

Abstract

The invention relates to a pretreatment device for deep purification of municipal tap water. The pretreatment device comprises negative and positive electrodes in pairs, an electrolysis power supply for supplying power to the electrodes and a water container, wherein a water inlet and a water outlet are arranged on the water container; two pairs of the electrodes in pairs are arranged and include a first electrode pair and a second electrode pair, a first water-pervious diaphragm is arranged between the negative electrode and the positive electrode of the first electrode pair, a second water-pervious diaphragm is arranged between the negative electrode and the positive electrode of the second electrode pair, the first water-pervious diaphragm and the second water-pervious diaphragm separate the positive electrode of the first electrode pair and the negative electrode of the second electrode pair from the water container, the negative electrode of the first electrode pair and the positive electrode of the second electrode pair are located in the water container and are directly contacted with water in the water container, and the positive electrode of the first electrode pair and the negative electrode of the second electrode pair are only contacted with seepage water of the water container. The device can deactivate bacteria in source water, degrade organic matters in the source water and reduce hardness of the source water.

Description

technical field [0001] The invention relates to a pretreatment device for deeply purifying municipal tap water, and belongs to the technical field of deep 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". [0003] At present, people usually use tap water as a source of drinking water, but most of the tap water plants at home and abroad still use the old process of sedimentation, fi...
