Problems solved by technology

[0004] However, the filter box disclosed in the prior art takes too much time to filter waste water, and cannot quickly separate waste water and impurities, requiring a lot of manpower and material resources
And during the discharge of the reacted waste water, the device in the prior art cannot keep the waste water in a state of being treated, thereby reducing the waste water treatment process.

Embodiment 1

[0047] Such as figure 1 and figure 2 As shown, a device for treating high-concentration formaldehyde wastewater includes an aluminum profile support frame 1, a vibrating filter device 2, a reactor 3, a connecting pipe 4, a protective device, a cleaning device, a rotating device 13, a rotating device mounting frame 16, water Using the electromagnetic valve 14 and the waste water pipe 15, the vibrating filter device 2 placed on the aluminum profile support frame 1, the two vibrating filter devices 2 are respectively located on both sides of the rotating device 13, and the rotating device 13 is placed on the rotating device. On the frame 16, the reactor 3 connected by the vibration filter device 2 is connected through the connecting pipe 4, and the waste water pipe 15 is installed on the rotating device 13 through the electromagnetic valve 14 for water.

[0048] Specifically, please refer to Figure 10 , the reactor 3 includes an inlet 8, an outlet 5, a cover body 6 and a seal...

Embodiment 2

[0069] Embodiment 2 is different from Embodiment 1 except that the vibrating device 209 is the same as other devices and installation positions.

[0070] Please focus on reference Figure 7 , the vibrating device 209 in Embodiment 2 includes a limit hole 217 arranged on the isolation plate 202, a moving block 216 placed in the limit hole 217, and the moving block 216 is installed on the filter box 206 One side, the rod three 221 hinged with the moving block 216, the disc 220 hinged with the rod three 221, the shaft 212 installed on the axis of the disc 220, and the shaft 212 is installed on the motor 210 , the motor 210 is installed on the housing 203 through a fixing seat 211 . The motor 210 is electrically connected to the control panel 222 .

[0071] The operating principle of the vibration device 209 in Embodiment 2 of the present invention is:

[0072]Manually control the control panel 222 to turn on the motor 210 , and pour industrial wastewater from the water inlet 2...

Abstract

The invention discloses a device and method for treating high-concentration formaldehyde wastewater. The device comprises an aluminum profile supporting frame, a connecting pipe and a reactor and further comprises a vibration filtering device, a protection device, a cleaning device and a rotating device. Due to the fact that impurities and foreign matter in wastewater need to be filtered firstly during treatment of formaldehyde wastewater at present, and in the prior art, time is consumed for wastewater filtration, and wastewater and impurities cannot be separated rapidly, the treatment process is accelerated, the treatment time is shortened, and manpower and material resources are saved by means of the vibration filtering device; and the rotating device ensures that the wastewater is always in a treated state, so that the wastewater treatment process is accelerated.

Description

technical field [0001] The invention relates to a device for treating high-concentration formaldehyde wastewater and a treatment method thereof, belonging to the technical field of wastewater treatment devices. Background technique [0002] POM production wastewater contains harmful substances such as formaldehyde, paraformaldehyde TOX, dioxane, methylal and phenols. It has the characteristics of high salt content and high COD. In the prior art, the POM production wastewater is treated through the Fenton reactor, but most of the Fenton reactors in the prior art do not have a device for cleaning impurities and foreign matter in the wastewater in advance, which leads to the entry of impurities and foreign matter Affects the treatment effect in the Fenton reactor. [0003] Chinese Patent Publication No. CN213037591U discloses a polyoxymethylene wastewater treatment device, including a base, a Fenton reactor and a support are fixedly connected to both sides of the top of the ba...
