Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to an ozone water treatment device. Background Art

[0002] Ozone is a strong oxidant. It has been used in water treatment for more than 100 years and can effectively deal with water pollution. The Chinese invention patent with publication number CN110526383 discloses a water treatment ozone oxidation treatment device. When in use, the ozone generated by the ozone generator is sent into the interior of the three-way pipe through the first conduit and the second conduit. When the water pump is turned on, the sewage is pumped. When the sewage enters the interior of the three-way pipe, the ozone is immediately dispersed and mixed with the water inside the three-way pipe under the rapid stirring of the stirring fan; the oxidation treatment device proposed by the present invention can fully stir the ozone and sewage, so that the sewage can be better oxidized. A Chinese invention patent with publication number CN112875839B discloses a high-efficiency ozone catalytic oxidation wastewater treatment device, which divides a water treatment tank into a first treatment section and a second treatment section, thereby extending the wastewater treatment path, extending the contact time between the wastewater and ozone, and promoting full mixing of the wastewater and ozone. The wastewater treated in the second treatment section is then passed back into the first treatment section via a return pipe, thereby achieving wastewater recycling treatment. In addition, the ozone that has been introduced can be fully utilized during the circulation process, thereby increasing the utilization rate of ozone and improving the effect of water treatment.

[0003] In the related art, the water treatment methods of existing ozone water treatment equipment mostly adopt the method of directly discharging the produced ozone into the water pipe and dissolving it through the flowing water source; or directly discharging the ozone into the sewage container and accelerating the ozone dissolution efficiency through stirring; however, the above-mentioned ozone treatment methods have certain defects in the actual treatment process. For example, when injecting ozone into the water pipe, due to the high water flow rate and the different cross-sectional sizes of the water pipes, the ozone cannot fully contact the water source in the water pipe when injected, which not only reduces the ozone treatment effect, but also causes ozone waste; when injecting ozone into the sewage container, due to the large volume of the sewage container, not only does it need to arrange different numbers of sampling input pipes in the sewage container, but the contact time between the ozone and the water source is short, and the ozone utilization rate cannot be improved, thereby reducing the water treatment effect. Summary of the invention

Through the provision of an ozone mixing component, not only is the water source to be treated divided into several equal parts, but each equal part of the water source is also treated separately through a separate ozone injection method, thereby improving the contact strength and range of the ozone water source and enhancing the ozone water treatment effect. Through the provision of an ozone circulation component, the ozone remaining from the reaction during the ozone water treatment is recycled and utilized, which not only avoids the waste of ozone, but also improves the adequacy of the ozone reaction, thereby solving the problem that when the existing ozone water treatment equipment treats sewage, the contact strength and time of ozone with the water source are not strong and short, thereby reducing the sewage treatment effect and causing ozone waste.

[0060] By driving the piston plate 83 up and down, not only can a negative pressure state be formed inside the negative pressure cylinder 81, that is, the ozone remaining from the reaction inside the treatment tank 3 can be extracted through the exhaust pipe 84, but also the extracted ozone can be squeezed so that the ozone is discharged to the inside of the mixing cylinder 2 through the exhaust pipe 85, forming a recycling of ozone, making full use of ozone, not only improving the ozone water treatment effect, but also reducing the water treatment cost;

[0067] Second switch valves are installed at both extraction ends of the Y-shaped tube 103, so as to realize the extraction of water sources at different levels by controlling different valves.

[0068] Embodiment 2: Based on embodiment 1, the difference is that;
