Description

Technical Field

[0001] The present application relates to the field of environmental engineering technology, and in particular to a pretreatment device for industrial wastewater. Background Art

[0002] Industrial wastewater treatment utilizes physical, chemical, and biological methods to treat wastewater, thereby reducing its impact on the environment. Industrial wastewater pretreatment is the treatment process prior to primary treatment, including processes such as screening, pulverization, skimming, sand removal, homogenization, and pH adjustment.

[0003] The pH value is one of the indicators that measure the acidity and alkalinity of industrial wastewater. Adjusting the pH value of industrial wastewater can improve the effectiveness of wastewater treatment. Based on the pH value of the wastewater and the target pH value of the wastewater, the staff will add the selected regulator to the wastewater treatment tank to ensure that the regulator and wastewater are fully mixed and reacted to achieve the effect of evenly adjusting the pH value of the wastewater.

[0004] However, in actual operation, due to the limited fluidity of wastewater in the wastewater treatment pool, the regulator and wastewater are not mixed evenly, which affects the uniformity of the pH value of the treated wastewater and affects the primary treatment of the wastewater.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application discloses a pretreatment device for industrial wastewater. Figure 1 and Figure 2 The industrial wastewater pretreatment device includes a treatment tank 1, a fixed component 2, a mixing component 3 and a partition plate 4.

[0035] Treatment tank 1 is used to hold industrial wastewater and a pH adjuster. The pH adjuster is a solution containing a dissolved pH-adjusting agent. Industrial wastewater is delivered to treatment tank 1 via sewage inlet pipe 7, and the pH adjuster is delivered to treatment tank 1 via adjuster inlet pipe 8. The adjuster and wastewater mix thoroughly to achieve a uniform pH adjustment. The treated industrial wastewater is then delivered to the next treatment step via outlet pipe 9. The water supply pipe is connected to an external pump to pump the treated industrial wastewater out of treatment tank 1.

[0036] Reference Figure 1 and Figure 3 , the fixed component 2 is arranged across the treatment pool 1, and the fixed component 2 is fixedly connected to the treatment pool 1. In this embodiment, the fixed component 2 includes an aisle board 21, a railing 22 and a fixing frame 23. The aisle board 21 is arranged across the treatment pool 1 for staff to walk; the railing 22 is arranged on both sides of the aisle board 21 to play a protective role. The fixing frame 23 is arranged on the aisle board 21, and the fixing frame 23 is used to install the mixing component 3; at the same time, the aisle board 21 is provided with a notch for the mixing component 3 to pass through.

[0037] Reference Figures 1 to 3 The mixing assembly 3 is fixed to the fixed assembly 2 and is used to mix the water in the treatment tank 1. The mixing assembly 3 includes a linear reciprocating drive member 31, a connecting rod 32, and a spoiler 33. The linear reciprocating drive member 31 is fixed to the fixed frame 23, and the driving direction of the linear reciprocating drive member 31 is vertical. The fixed end of the connecting rod 32 is fixedly connected to the driving end of the linear reciprocating drive member 31. One or more spoilers 33 are provided and fixedly connected to the connecting rod 32.

[0038] In this embodiment, the linear reciprocating drive element 31 includes a reciprocating drive motor 311 and a rack 312. The motor's driving end is a ring gear, and the rack 312 is vertically arranged. The driving end of the reciprocating drive motor 311 is mated and connected to the rack 312, allowing the motor to drive the rack 312 to move up and down. A plurality of rollers 24 are provided on the side of the fixed frame 23 near the rack 312. The rollers 24 abut against the rack 312, constraining the rack 312 and allowing it to move up and down.

[0039] Reference Figure 1 and Figure 3 The connecting rod 32 is fixedly connected to the rack 312, so that the linear reciprocating drive member 31 can drive the connecting rod 32 and the spoiler 33 to flow up and down, thereby promoting the flow of water in the treatment tank 1, improving the uniformity of the mixing of industrial wastewater and the pH regulator, and improving the uniformity of the pH value of the treated industrial wastewater.

[0040] In other embodiments, the linear reciprocating drive member 31 may also be a cylinder, a linearly driven hydraulic motor or other equipment.

[0041] Reference Figure 1 and Figure 2 In this embodiment, the spoiler 33 is conical in shape, and the distance from the spoiler 33 to the connecting rod 32 increases as it moves away from the linear reciprocating drive member 31. Consequently, when the linear reciprocating drive member 31 drives the spoiler 33 up and down, the spoiler 33's water disturbance effect is enhanced while reducing the resistance encountered during movement. The spoiler 33 is provided with a plurality of first through-holes 331 for the water to pass through, further enhancing the spoiler 33's water disturbance effect in the treatment tank 1 and further reducing the resistance encountered during movement.

[0042] Reference Figure 1 and Figure 2 , the partition plate 4 is arranged in the treatment tank 1, and the partition plate 4 is fixedly connected to the inner wall of the treatment tank 1, and a gap is provided between the partition plate 4 and the bottom wall of the treatment tank 1 for the water to flow. There are two partition plates 4, and the two partition plates 4 are arranged on both sides of the mixing component 3. The partition plate 4 is immersed in the water body of the treatment tank 1, and the upper edge of the partition plate 4 is at a certain distance from the liquid surface of the water body in the treatment tank 1. The two partition plates 4 divide the water body in the treatment tank 1 into three small water bodies. Therefore, when the spoiler 33 moves up and down, it can promote the flow effect between the water bodies on both sides of the treatment tank 1 and the middle water body, thereby further improving the uniformity of the mixing of industrial wastewater and the pH regulator.

[0043] Reference Figure 1 and Figure 2 The partition plate 4 is provided with a plurality of second through-holes 41 for water to pass through, and the diameter of the through-holes increases as it moves away from the bottom wall of the treatment tank 1. The second through-holes 41 in the partition plate 4 allow water in the treatment tank 1 to flow through and improve the uniformity of mixing between the industrial wastewater and the pH regulator. The diameter of the through-holes increases from bottom to top, allowing the spoiler 33 to carry more water upward during its upward movement, allowing more water to flow through the through-holes above the partition plate 4 to the water on both sides of the treatment tank 1, further improving the uniformity of water mixing in the treatment tank 1.

[0044] Example 2

[0045] The difference between this embodiment 2 and embodiment 1 is that:

[0046] Reference Figure 4 In this embodiment, the linear reciprocating drive member 31 is a cylinder, and the driving end of the linear reciprocating drive member 31 is fixedly connected to the connecting rod 32.

[0047] Example 3

[0048] The difference between this embodiment 3 and embodiment 1 is that:

[0049] Reference Figure 5 A pretreatment device for industrial wastewater also includes an airbag 5 and a flexible rope 6; one end of the flexible rope 6 is fixedly connected to the airbag 5, and the other end of the flexible rope 6 is fixedly connected to the side wall of the treatment tank 1; the airbag 5 is fixedly connected to the external air extraction equipment, and the airbag 5 is immersed in the water of the treatment tank 1. In this embodiment, two airbags 5 are provided, and the two airbags 5 are relatively arranged on both sides of the treatment tank 1. Therefore, the staff can change the volume interval of the two airbags 5 by filling and deflating the two airbags 5 at intervals; thereby further improving the fluidity of the water in the treatment tank 1, improving the uniformity of the mixing of industrial wastewater and pH value, and improving the uniformity of the pH value mixing after the industrial wastewater is treated.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
