Embodiment 1

[0062] The urban roof water storage device of the present embodiment, see figure 1 , comprising at least one pair of negative and positive electrodes, an electrolytic power supply 3 and a water container 1 for supplying power to the negative and positive electrodes, a water-permeable diaphragm 21 is provided between the paired negative electrodes 22 and positive electrodes 23, and a window is provided on the top of the water container 1 , the cathode electrode 22 is located at the bottom of the water container 1, and the anode electrode 23 is located at the window.

[0063]The water container 1 is divided into an upper chamber 13 communicated with the water inlet pipe and a lower chamber 14 communicated with the water outlet pipe by a partition 17 . The spacer 17 includes two layers of splints with holes oppositely arranged and a physical adsorption filter layer arranged between the two layers of splints with holes. In use, the cathode electrode 22 is in contact with the wate...

Embodiment 2

[0087] The urban roof water storage device of the present embodiment is an improvement on the basis of the first embodiment, and the difference from the first embodiment is:

[0088] In this embodiment, the water container 1 is manually filled with tap water. Still taking the city supply tap water in Dalian, China as an example, the electrolysis 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 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 mm.

Embodiment 3

[0090] The urban roof water storage device of the present embodiment is an improvement on the basis of the first embodiment, and the difference from the first embodiment is that in the present embodiment, the positive electrode 23 positioned on the outside of the water-permeable diaphragm 21 has a number of through holes, The water-permeable membrane 21 is a nanofiltration membrane.

[0091] 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.

[0092] The urban roof water storage device of the present invention is not limited to the specific technical solutions described in the above embodiments, for example: 1) The electrolysis power supply 3 is a DC pulse power supply with a high level and narrow pulse width or a forward voltage level greater than a reverse voltage power supply; 2) The wat...

Abstract

The invention relates to an urban roof water storage device, belonging to the technical field of domestic drinking water quality advanced treatment. The urban roof water storage device comprises at least one pair of negative and positive electrodes, an electrolysis power source for supplying power to the negative and positive electrodes, and a water container, wherein a water-permeable diaphragm is arranged between the negative electrode and positive electrode in pair; the top of the water container is provided with a window; the negative electrode is arranged on the bottom in the water container; the positive electrode is arranged at the window; the water container is divided by a partition into an upper chamber which communicates with a water inlet pipe and a lower chamber which communicates with a water outlet pipe; and the partition comprises two oppositely arranged porous splints and a physical adsorption filter layer arranged between the two porous splints. When in use, the negative electrode contacts water in the water container, and the positive electrode only contacts the water container through the permeated water of the water-permeable diaphragm. The urban roof water storage device simultaneously adopts the physical and chemical processes to purify water stored in an elevated water tank installed on the top layer of the high-rise building in the urban water supply pipe network.

Description

technical field [0001] The invention relates to an urban roof water storage device, which 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. In some extremely poo...
