Embodiment 1

[0060] The municipal tap water deep purification device of the present embodiment, see figure 1 , including a pair of negative electrodes 22 and positive electrodes 23, a water-permeable diaphragm 21, an electrolysis power supply 3 for supplying power to the negative and positive electrodes, and a container 1 with water, and the water-permeable diaphragm 21 separates the paired negative electrodes 22 and the positive electrodes 23 from each other Open, the water-permeable diaphragm 21 is a water-permeable diaphragm made of a non-conductive material, and the water-permeable diaphragm 21 has water-permeable micropores with uniform apertures. The water-permeable micropores with uniform pore size are roughly uniform in size and shape. For example, all the holes in a membrane have the same shape, such as oval holes, triangular holes, and so on. The pore sizes in a membrane are all the same size pores, and so on.

[0061] In use, the cathode electrode 22 is in contact with the wate...

Embodiment 2

[0087] The deep purification device for municipal tap water in this embodiment is an improvement on the basis of Embodiment 1, and the difference from Embodiment 1 is:

[0088] In this embodiment, the container 1 is manually filled with tap water. Taking the city-supplied tap water in Dalian, China as an example, the electrolytic power supply 3 adopts an alternating pulse power supply whose forward voltage level is greater than the reverse voltage level, and the average voltage is 15V. The water-permeable membrane 21 adopts a microfiltration membrane, and the distance δ between the microfiltration membrane and the anode electrode 23 located outside the membrane is 15 mm.

Embodiment 3

[0090] The deep purification device for municipal tap water in this embodiment is an improvement on the basis of Embodiment 1. The difference from Embodiment 1 is that in this embodiment, the anode electrode 23 located outside the water-permeable membrane 21 has a number of through holes. , the water-permeable membrane 21 adopts a nanofiltration membrane.

[0091] In this embodiment, the tap water supplied by the city in Dalian, China is 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 an advanced purifying device for municipal tap water, belonging to the technical field of advanced treatment of water quality of domestic drinking water. The purifying device comprises at least one pair of negative and positive electrodes, a water-permeable diaphragm, an electrolysis power supply for supplying power to the negative and positive electrodes and a container with water, wherein the water-permeable diaphragm separates the negative electrode and positive electrode in pair; the water-permeable diaphragm is made from a non-conductive material and has water-permeable micropores with uniform pore diameter; and in use, the negative electrode contacts with water in the container, and the positive electrode only contacts with the water permeating through the water-permeable diaphragm in the container. The purifying device has the advantages that few toxic byproducts are generated during degradation of organic matters in water and the toxic byproducts do not enter the degraded water.

Description

technical field [0001] The invention relates to a deep purification device for municipal tap water, belonging 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. The increasingly intensified water pollution has posed a major threat to the survival and safety of human beings, and has become a major obstacle to the sustainable development of human health, economy and society. According to a survey by the world's authoritative organization, drinking unsanitary water causes at least 20 million deaths worldwide every year. Therefore, water pollution is called "the world's number one killer". [0003] Most water plants at home and abroad still use the old process methods of precipitation, filtration and chlorination to simply process river water or groun...
