Embodiment 1

[0036] Water disinfection equipment, see figure 1, including water inlet pump 1, No. 1 liquid control valve 2, reaction device 3, diaphragm 4, anode 5, cathode 6, exhaust valve 7, power supply 8, first gas control valve 9, gas dryer 10, ozone generator 11 , ozone aeration device 12, No. 2 liquid control valve 13 and gas-liquid separator 14; No. 1 liquid control valve 2 is located between the water inlet pump 1 and the reaction device 3; The reaction device 3 is provided with a diaphragm 4, and the diaphragm 4 will react The device is divided into an anode chamber and a cathode chamber; the water inlet 3-1 of the anode chamber is connected to the water inlet pump 1, and the water outlet 3-3 of the anode chamber is connected to the water inlet 3-4 of the cathode chamber; the second liquid control valve 13 is located in the reaction device 3 and the gas-liquid separator 14; the cathode chamber water outlet 3-2 is connected to one end of the No. 2 liquid control valve 13, and the ...

Embodiment 2

[0040] Water disinfection equipment, see figure 2 , is basically the same as Embodiment 1, except that it also includes an ozone tail gas destroyer 15, a second gas control valve 16, a gas phase ozone concentration monitor 17, a gas flow meter 18 and a check valve 19. The air inlet of the ozone tail gas destroyer 15 is connected with the gas-liquid separator gas outlet 14-2, and the gas outlet of the ozone tail gas destroyer 15 is connected with the second gas control valve 16; the ozone generator 11, the gas phase ozone concentration monitor 17, the gas flow rate The meter 18 and the check valve 19 are connected sequentially; the check valve 19 is connected with the ozone aeration device 12 through the cathode chamber air inlet 3-5.

[0041] The ozone tail gas destroyer 15 can remove the residual ozone gas in the tail gas after gas-liquid separation to ensure safety and environmental protection; the gas phase ozone concentration monitor 17 and the gas flow meter 18 can reali...

Embodiment 3

[0043] Water disinfection equipment, see image 3 , is basically the same as Example 2, the only difference is that the ozone aeration device 12 is a hydraulic jet, a pipeline gas-liquid mixer, a gas-liquid mixing pump, etc. placed outside the reaction device 3, and is located at the anode chamber water outlet 3 -3 and the cathode chamber water inlet 3-4, and communicate with the ozone generating device 25.

Abstract

The invention provides a water disinfection device and a water disinfection method performed through the water disinfection device. The water disinfection device comprises a water inflow device, a reaction device, a power source, an ozone aerating device, a gas and liquid separator and an ozone generating device. A partition film is arranged in the reaction device and divides the reaction device into an anode chamber and a cathode chamber. An anode and a cathode are arranged in the anode chamber and the cathode chamber respectively and connected with the positive electrode and the negative electrode of the power source arranged outside the reaction device respectively. The anode chamber is communicated with the cathode chamber. An exhaust valve is arranged at the top end of the anode chamber. The water inlet device is communicated with the anode chamber of the reaction device, and the gas and liquid separator is communicated with the cathode chamber of the reaction device. The ozone generating device is communicated with the cathode chamber through the ozone aerating device. Compared with the prior art, the device is simple and compact in structure, small in occupied area, convenient to run and manage, good in processing effect and high in processing efficiency.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, and in particular relates to a water body disinfection equipment, and also relates to a method for using the equipment to carry out water body disinfection. Background technique [0002] The spread of bacteria and viruses in water seriously endangers human health and ecological safety. Disinfection is a necessary part of water treatment process. At present, water disinfection technologies mainly include liquid chlorine, chloramine, chlorine dioxide, ultraviolet rays, ozone, etc. Chlorine-containing disinfectants are widely used and have a good bactericidal effect, but the by-products have "three-infection" effects, and they need to be stored, which is inconvenient to use. Ultraviolet disinfection is safe, but the energy consumption is high, and the treatment effect is greatly affected by the water quality. Ozone disinfection effect is good, the speed is fast, and it has multiple functio...
