Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a device for treating production wastewater of a water plant. Background Art

[0002] A water plant is a facility responsible for treating and supplying water to residents in a city or region. In the process of treating raw water, the water plant will produce wastewater, such as equipment flushing water, sludge treatment liquid, disinfection wastewater, sludge water, etc. These wastewaters need to go through a special treatment system to ensure that they do not have a negative impact on the environment. When treating the wastewater, the wastewater needs to be placed in an ultraviolet sterilization pool and sterilized and disinfected by ultraviolet lamps. When ultraviolet rays are used to sterilize and disinfect the wastewater in the pool, since the ultraviolet lamp is at one end of the ultraviolet sterilization pool, the wastewater at the end of the ultraviolet sterilization pool far away from the ultraviolet lamp is less exposed to light, resulting in insufficient sterilization effect, and the uniformity and adequacy of the sterilization of the wastewater in the ultraviolet sterilization pool cannot be guaranteed. Summary of the invention

[0003] The object of the present invention is to provide a treatment device for wastewater produced by a waterworks to solve the problems raised in the above-mentioned background technology.

[0016] Preferably, the driving module also includes a mating slot and a four-level contact switch. The mating slot is opened at the rear end of the right side of the inner cavity of the ultraviolet sterilization pool. The four-level contact switch is embedded in the right side wall of the inner cavity of the ultraviolet sterilization pool.

The peripheral terminal receives the signal and controls the first-level drive motor 51 to turn off and the second-level drive motor 49 to turn on.

[0039] Working principle: When the irradiation time of the wastewater in the ultraviolet sterilization pool 1 reaches half of the predetermined time, the hydraulic rod 31 is controlled to start through the external terminal, and the top frame 32, the drive module 5 and the transfer module 4 are driven to descend through the output end at the bottom of the hydraulic rod 31.

The three-level contact switch 513 transmits the signal to the external terminal, and the external terminal receives the signal and controls the hydraulic rod 31 to close. At this time, the wastewater close to the ultraviolet lamp is framed between the transfer plate 41 and the side baffle 42, the outer plate 43, and the inner plate 44. At the same time, the external terminal controls the first-level drive motor 51 to start, and the first-level drive motor 51 drives the drive screw 52 to rotate, so that the drive plate 53 drives the transfer plate 41 to move right. Until the right side of the inner plate 44 is in contact with the ultraviolet sterilization pool 1 and the right side of the outer plate 43 is in the fitting groove 515, the outer plate 43 is in contact with the four-level contact switch 516 at this time, and the four-level contact switch 516 transmits a signal to the external terminal, which receives the signal and controls the first-level drive motor 51 to turn off and the second-level drive motor 49 to turn on, so that the second-level drive motor 49 drives the threaded rod 410 to rotate, and the external sleeve 411 drives the two groups of side baffles 42 to move back to back, until the side baffles 42 are in contact with the ultraviolet sterilization pool 1.

At this time, the transfer of proximal wastewater and distal wastewater is completed, and at the same time, the hydraulic rod 31 is controlled to open, so that the top frame 32 drives the transfer module 4 to rise slowly until the transfer module 4 is separated from the wastewater.

[0040] After the peripheral terminal detects that the hydraulic rod 31 has completed its contraction, it controls the first-level drive motor 51 to turn on, so that the drive screw 52 rotates, so that the drive plate 53 drives the transfer plate 41 to move left, until the transfer plate 41 contacts the second-level contact switch 48 on the right side of the first-level connecting plate 34, and the second-level contact switch 48 transmits a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the first-level drive motor 51 to turn off and the second-level drive motor 49 to turn on, so that the threaded rod 410 rotates, and cooperates with the external sleeve 411 to make the two groups of side baffles 42 move relative to each other until the limit plate 412 contacts the second-level contact switch 48, and the second-level contact switch 48 transmits a signal to the peripheral terminal, and the peripheral terminal controls the second-level drive motor 49 to turn off, thereby completing the resetting of the device.
