Problems solved by technology

[0009] At present, there is the possibility of coronavirus spreading in the sewers and inspection wells of hospitals and the isolation points where suspected patients are located, but there are very few small and efficient vehicle-mounted devices for disinfection and deodorization that can be placed in inspection wells. Inventions in related fields mainly focus on sediments in pipelines Elimination of viruses and pathogenic bacteria in inspection wells without inventions

Embodiment 1

[0048] A kind of disinfection and deodorization device in vehicle inspection well, such as figure 1 with figure 2 Shown. The device is mainly composed of an ozone generator 1, a variable frequency air compressor 2, a reactor cable retracting device 3, a reactor cable 4, and a main reactor 5. The main reactor includes a frame cable reel 51, a UV lamp set 52, a reactor frame cable 53, a nano aeration disk arm frame 54; an online water quality monitor 55; an ultrasonic generator 56, a nano bubble aeration disk 57, 58- Frame cable reel motor. The main reactor 5 is connected to the variable frequency air compressor 2 and the ozone generator 1 through the reactor cable 4.

[0049] Such as image 3 As shown, the main reactor includes a rectangular frame of the main reactor, the rectangular frame of the main reactor is equipped with an ultrasonic generator 56 and an ultraviolet lamp group 52, and two sides of the rectangular frame of the main reactor are also provided with a nano aerat...

Embodiment 2

[0062] An enhanced ozone nanobubble disinfection and deodorization device that can be placed in an inspection well. The basic components and disinfection and deodorization methods are the same as those in Example 1. The specific structure and implementation are as follows:

[0063] In this example, the diameter of the inspection well near a community with suspected patients is 700cm, and the diameter of the sewage pipeline in the inspection well is 2000cm. The sewage and gas in the pipeline are sampled three times, and the detection is performed according to the fluorescence quantitative PCR and sequencing of molecular biology. The results show There are Escherichia coli, Salmonella, and Rotavirus exceeding the standard limit. The concentration of hydrogen sulfide is 3mg / L, ammonia is 0.75mg / L, and the average flow rate of sewage in the pipeline is 0.7m / s.

[0064] Transport the vehicle-mounted inspection well water purification and deodorization device to the inspection well of th...

Abstract

The invention relates to a vehicle-mounted device for disinfection and deodorization of a sewage inspection well. A closed-state main reactor in the device is inserted into the sewage inspection wellfrom the upper portion of the inspection well through a pipe cable winding and unwinding device; the closed-state main reactor descends to the bottom of the well to be perpendicular to the flowing direction of sewage in a pipeline, and a water quality online monitor is turned on; the reactor is slowly unfolded by controlling a frame inhaul cable, and an ultrasonic generator is turned on; an ozonegenerator and an ultraviolet lamp tube are turned on, so that ozone releases a large number of nanobubbles from a nanobubble aeration disc through an air compressor, so that bacteria and viruses in the pipeline are efficiently inactivated, and odor in the pipeline is degraded; after disinfection is completed, the main reactor is folded by a frame inhaul cable folding and unfolding device, and thereactor is pulled out of the sewage inspection well by a cable pipe folding and unfolding device. The device can be placed on a vehicle; manual underground operation is not needed; and the position ofan inspection well to be disinfected and deodorized can be adjusted as required. The ultrasonic, ultraviolet light catalysis and ozone nano-bubble compound disinfection technology is high in treatment efficiency, and the possibility that viruses and pathogenic bacteria in sewage and aerosol diffuse to the environment is reduced.

Description

Technical field [0001] The invention belongs to the technical field of urban sewage disinfection, and relates to a vehicle-mounted device for the disinfection and deodorization of sewage inspection wells, and in particular to a realization of sewage and aerosols in inspection well pipelines through ultrasonic, ultraviolet photocatalysis and ozone nanobubble composite technology Sterilize and deodorize device. Background technique [0002] There may be the possibility of virus residues in the drainage pipes of the communities where patients with the new crown virus are located, and potential hazards to the lives and health of community residents, urban sewage treatment facility operators, environmental protection practitioners, etc., must be paid enough attention. [0003] Ultraviolet disinfection is currently a common treatment process in urban sewage treatment facilities, hospital sewage treatment facilities and water supply systems. Ultraviolet is a kind of light that is invisib...
