Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to a sewage treatment device with a disinfection unit. Background Art

[0002] Wastewater treatment is a type of purification process used to make wastewater meet the water quality requirements for discharge into a certain water body or reuse. Wastewater treatment is widely used in construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment and catering. Wastewater treatment is also an important part of environmental protection and sustainable development, and is of great significance to maintaining ecological balance and protecting human health. In the prior art, the discharged sewage is mostly pretreated through a screen and a regulating tank, and then treated by an activated sludge method and a biofilm method. The treated sewage is then precipitated, filtered, and disinfected before being discharged into a natural water body or recycled. However, in traditional treatment operations, the amount of flocculant is adjusted and added according to the amount of sewage in the sedimentation tank after the sewage is discharged into the sedimentation tank, which makes it difficult for the flocculant to diffuse in the water, resulting in low flocculation efficiency. After the sewage is flocculated and precipitated, the clean water after flocculation needs to be disinfected. Conventional disinfection methods are single ultraviolet lamp or disinfectant treatment. Although ultraviolet lamps are highly efficient and have no chemical residues, ultraviolet lamps have poor penetration in water. When disinfectants are used for disinfection, chemical residues remain in the water, greatly affecting people's health.

[0029] When the chlorine dioxide liquid is generated inside the chlorine dioxide generator 67, the pressure pump 68 is started to divert the chlorine dioxide liquid generated in the chlorine dioxide generator 67 through the three-way pipe 69 to the two cylindrical sprayers 70. Then the chlorine dioxide liquid is evenly sprinkled through the openings on the outside of the two cylindrical sprayers 70 to mix with the clarified liquid after sewage treatment. An array of ultraviolet disinfection lamps 71 are also provided on the top of the inner wall of the second mounting frame 66. The tops of the ultraviolet disinfection lamps 71 are fixed to the second mounting frame 66 by bolts. When the ultraviolet disinfection lamps 71 are started, the liquid in the disinfection tank 61 is disinfected by ultraviolet light.

[0030] The operating panel 22 is used to operate and stop the second stepper motor 32, the drive motor 37, the first electric push rod 45, the second electric cylinder 53, the chlorine dioxide generator 67 and the pressure pump 68, and monitor the water flux at the first electromagnetic flowmeter 11, the second electromagnetic flowmeter 26, and the third electromagnetic flowmeter 55. The device is tilted on the ground, with one end of the water inlet pipe 1 higher and one end of the disinfection unit 6 lower.

[0031] The working process and principle of the present invention are as follows: First, according to the water quality of the treated sewage, a sufficient amount of solid flocculant is placed in the storage barrel 24. The solid flocculant includes but is not limited to polyaluminum chloride, polyferric sulfate, polyacrylamide, etc., and then clean water is injected into the stirring barrel 23 through the second electromagnetic flowmeter 26. At this time, the second electromagnetic flowmeter 26 records the amount of water injected into the stirring barrel 23, and then the first stepper motor 30 is started to drive the spiral conveyor belt 31 to rotate, so as to transport the solid flocculant in the storage barrel 24 to the stirring barrel 23 for mixing. According to the water quality, the amount of solid flocculant transported by the spiral conveyor belt 31 is adjusted to adjust the concentration of the liquid flocculant in the stirring barrel 23. At the same time, after the solid flocculant enters the stirring barrel 23, the second stepper motor 32 is started to drive the stirring shaft 34 to rotate, so as to stir the water in the stirring barrel 23, thereby accelerating the dissolution of the solid flocculant; After the liquid flocculant is made, the sewage pre-treated by the grid and the regulating tank is discharged into the sedimentation tank 41 through the water inlet pipe 1. At this time, the first electromagnetic flowmeter 11 monitors the amount of sewage flowing in from the water inlet pipe 1 and starts the drive motor 37 synchronously. When the drive motor 37 is started, it drives the roller in the peristaltic pump 36 to rotate and squeeze the elastic hose 38, so that the liquid flocculant in the stirring barrel 23 is transported to the installation pipe 12 through the flocculant discharge pipe 35, the elastic hose 38, and the hose connector 13. Then, the liquid flocculant and the sewage are pushed to rotate by the stirring blade 15, so that the liquid flocculant and the sewage are fully mixed, and the sewage mixed with the flocculant is discharged into the sedimentation tank 41. At this time, the bottom plug 50 is inserted into the sedimentation tank 41 to prevent the sewage in the sedimentation tank 41 from flowing out, and the top of the gate plate 54 contacts the bottom of the second electric cylinder mounting plate 52 to separate the sewage in the sedimentation tank 41 from the disinfection unit; When the flocculated sludge in the sewage in the sedimentation tank 41 sinks to the bottom, the second electric cylinder 53 is started to drive the gate plate 54 to descend into the gate plate sleeve 51 until the top of the gate plate 54 is slightly higher than the height of the flocculants in the sedimentation tank 41. At this time, the clarified liquid above the sedimentation tank 41 flows into one end of the disinfection unit 6, and then the first electric push rod 45 is started to drive the bottom plug 50 to move upward, so that the sludge in the sedimentation tank 41 is discharged through the mud outlet pipe 44. At this time, the third electromagnetic flowmeter 55 records the amount of discharged sludge, and the amount of discharged sludge is subtracted from the amount of water inlet to obtain the amount of disinfectant required for the remaining water flow. At this time, the chlorine dioxide generator 67 is started to produce chlorine dioxide disinfectant; At this time, the water flows through the four activated carbon racks 63, filtering the remaining organic compounds, heavy metal ions, chlorine and chlorinated compounds and some microorganisms in the water flow, and at the same time eliminating the odor and color in some sewage. When the water flows out of the four activated carbon racks 63 and enters the bottom of the second mounting rack 66, the booster pump 68 is started at this time to divert the chlorine dioxide liquid generated in the chlorine dioxide generator 67 through the three-way pipe 69 to the two cylindrical sprayers 70. Subsequently, the chlorine dioxide liquid is evenly sprinkled through the openings on the outside of the two cylindrical sprayers 70 to mix with the clarified liquid after sewage treatment, and the ultraviolet disinfection lamp 71 is started synchronously to perform ultraviolet disinfection on the liquid in the disinfection tank 61, thereby completing the sewage treatment process.
