Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a backwashing type high-turbidity water sedimentation tank. Background Art

[0002] From the appearance, high turbidity sewage is obviously turbid and has low transparency. This is because it contains a large amount of suspended particles, which make it difficult for light to penetrate. The sewage looks muddy, cloudy or opaque. Since sewage may contain various organic and inorganic substances, in addition to being turbid, its color is often darker. It may appear in different shades such as gray, brown, and black. The specific color depends on the source of the sewage and the types of pollutants it contains.

[0003] There are still some shortcomings in the existing technology for sedimentation treatment of high turbidity sewage. Since the suspended particulate matter in high turbidity sewage is much higher than that in general sewage, the equipment carrying capacity is limited during the treatment process, which may cause a sharp drop in the effluent quality. The treatment process needs to be further improved and optimized. Summary of the invention

[0020] Description: When high turbidity water flows through the linked inclined plate sedimentation mechanism, the sedimentation area is increased and the sedimentation distance of suspended particles is shortened due to the setting of the sedimentation barrier inclined plate, thereby improving the sedimentation efficiency.

[0021] Preferably, a plurality of crowding sedimentation mechanisms are provided in the sedimentation tank body, and the crowding sedimentation mechanisms include two crowding sedimentation support shafts arranged in parallel and rotatably connected in the sedimentation tank body, and a crowding sedimentation guide plate is fixed on the crowding sedimentation support shaft;

[0027] Preferably, an acoustic wave agglomeration mechanism is provided in the sedimentation tank body, and the acoustic wave agglomeration mechanism comprises an agglomeration mechanism support rod horizontally extending and fixed in the sedimentation tank body, and an agglomeration mechanism accommodating shell is suspended and fixed to the lower side of the agglomeration mechanism support rod through a supporting cable;

[0029] The sound wave generator is a sound wave generator of the prior art, and its sound wave generation frequency is 20kHz to 30kHz.

[0030] Description: The ultrasonic generator is used to intermittently generate ultrasonic waves.

The ultrasonic vibration energy will form a specific energy field in three-dimensional space. The ultrasonic vibration energy suspended particles vibrate together with the medium, and the suspended particles of different sizes have different relative vibration speeds. Therefore, the suspended particles will collide and bond with each other, causing the suspended particles to agglomerate with each other, which is conducive to the faster precipitation of the suspended particles.

[0031] Preferably, a plurality of sedimentation interception slow-flow baffles arranged in parallel are fixed to the inner bottom of the sedimentation tank body.

[0032] Note: Each sedimentation interception slow-flow baffle can play a buffering and barrier effect to prevent the settled suspended particles from being disturbed by the water flow.

[0036] Description: After high turbidity water is treated by sedimentation, it becomes clean water. The clean water will overflow through the sedimentation tank outlet slot into the sedimentation tank outlet flow slot, and finally be discharged from the outer end of the sedimentation tank outlet flow slot. During the water discharge process, the outlet filter net is used to assist in filtering the clean water, which is beneficial to improve the outlet water quality; and the inclination angle of each outlet filter net can be adjusted to facilitate slag discharge.

[0037] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0038] 1. The structure of the present invention is reasonably designed, and the decentralized water inlet mechanism can transport the high turbidity water to be treated to the interior of the sedimentation tank more evenly and stably, avoiding uneven water distribution causing water short circuit and affecting the sedimentation effect;

[0039] 2. The present invention is easy to operate. When high-turbidity water flows through the linkage inclined plate sedimentation mechanism, the sedimentation area is increased and the sedimentation distance of suspended particles is shortened under the blocking effect of multiple sedimentation barrier inclined plates, thereby improving the sedimentation efficiency. The two adjacent sedimentation barrier inclined plates are synchronously driven by a linkage driving connecting rod, so that the sedimentation barrier inclined plates can be synchronously deflected around their respective inclined plate support rotating shafts, thereby making the multiple sedimentation barrier inclined plates always maintain a parallel state, thereby improving the stability of water flow;

[0040] 3. The crowded sedimentation mechanism of the present invention forms a "crowded flow channel" in the space between the two crowded sedimentation guide plates. When the high turbidity water flows through the "crowded flow channel", the "crowded flow channel" presents a contraction structure that is first wide and then narrow along the flow direction of the high turbidity water, forcing the suspended particles in the high turbidity water to crowd together, increasing the concentration of suspended particles in the local space, accelerating the mutual interference between the suspended particles, and forming a crowded sedimentation phenomenon that is beneficial to accelerating the sedimentation of the suspended particles;

[0041] 4. In the present invention, the guide plate slotting mechanism is used to control the opening of each settling flow slot, thereby adjusting the actual working effect of the crowded settling mechanism. Multiple settling flow slots are connected to each settling flow adapter slot in a one-to-one correspondence, and the settling flow slots and the settling flow adapter slots together form a "slotting mechanism channel";

[0042] 5. In the present invention, an ultrasonic generator is used to intermittently generate ultrasonic waves. The ultrasonic vibration energy is transmitted to the high-turbidity water through the transmission effect of the agglomeration mechanism housing shell. The ultrasonic vibration energy will form a specific energy field in three-dimensional space. The ultrasonic vibration energy suspended particles vibrate together with the medium, and the suspended particles of different sizes have different relative vibration speeds. Therefore, the suspended particles will collide and adhere with each other, so that the suspended particles are agglomerated with each other, which is conducive to the faster precipitation of the suspended particles.

[0043] 6. The present invention utilizes a water outlet filter to assist in filtering clean water, which is beneficial to improving the quality of the effluent water; and the inclination angle of each water outlet filter can be adjusted to facilitate slag discharge.

[0100] In the actual application process of the present invention, the Figure 1 For example, the left-right direction of the sedimentation tank body 100 is the length direction of the sedimentation tank body 100, which is perpendicular to the Figure 1 The direction of the plane is the width direction of the sedimentation tank body 100;

[0101] The high turbidity water to be treated is first transported to the interior of the dispersed water inlet overflow tank 12 by using a delivery pump of the prior art. The extension direction of the dispersed water inlet overflow tank 12 is parallel to the width direction of the sedimentation tank body 100, so that the high turbidity water is evenly dispersed in the dispersed water inlet overflow tank 12. The high turbidity water in the dispersed water inlet overflow tank 12 then enters the interior of the dispersed water inlet buffer box 11 through the dispersed water inlet overflow slot 120. The high turbidity water in the dispersed water inlet buffer box 11 finally enters the interior of the sedimentation tank body 100 through a plurality of dispersed water inlet slots 110.

[0102] During this process, the overflow auxiliary drive motor 133 drives the overflow auxiliary drive shaft 13 to rotate through gear transmission, and the overflow auxiliary drive shaft 13 drives the multiple overflow auxiliary drive plates 131 to rotate together, so as to stir the high turbidity water in the dispersed water inlet overflow tank body 12, thereby preventing the suspended matter in the high turbidity water from being excessively accumulated at the bottom of the dispersed water inlet overflow tank body 12;

[0103] The two crowding sedimentation support shafts 41 in each crowding sedimentation mechanism 40 are extended along the width direction of the sedimentation tank body 100, and the two crowding sedimentation support shafts 41 are arranged in a vertical direction;

[0104] The rotation of the crowding and settling support shaft 41 can control the deflection of the crowding and settling guide plate 42, thereby adjusting the angle between the two crowding and settling guide plates 42;

[0105] The space between the two crowded sedimentation guide plates 42 forms a "crowded flow channel". When the high turbidity water flows through the crowded sedimentation mechanism 40, that is, in the process of flowing through the "crowded flow channel", along the flow direction of the high turbidity water, the "crowded flow channel" presents a contraction structure that is first wide and then narrow, forcing the suspended particles in the high turbidity water to crowd together, so that the concentration of suspended particles in the local space increases, accelerating the mutual interference between the suspended particles, and forming a crowded sedimentation phenomenon, which is beneficial to accelerating the sedimentation of the suspended particles.

[0106] The guide plate driving motor 432 is a servo motor of the prior art. The output shaft of the guide plate driving motor 432 drives the crowding and settling support shaft 41 to rotate through the meshing connection between the second active worm 433 and the second driven worm gear 431, thereby causing the crowding and settling support shaft 41 to drive the crowding and settling guide plate 42 to deflect.

[0107] The guide plate slot mechanism 44 is used to control the opening of each settling flow slot 441, thereby adjusting the actual working effect of the crowding settling mechanism 40;

[0108] The plurality of sedimentation flow slots 441 are connected to the respective sedimentation flow adapting slots 443 in a one-to-one correspondence, and the sedimentation flow slots 441 and the sedimentation flow adapting slots 443 together form a "slot mechanism channel";

[0109] The opening and closing control driving rod 446 is an electrically controlled telescopic rod of the prior art. The extension or retraction of the inner rod of the opening and closing control driving rod 446 can drive the slotted opening and closing control plate 442 to slide inside the crowded sedimentation guide plate 42, thereby controlling the overlapping area between the sedimentation flow slot 441 and the sedimentation flow adaptation slot 443, thereby controlling the opening degree of the "slotted mechanism channel";

[0110] The axis of the opening and closing control fixed cylinder 444 is arranged along the width direction of the sedimentation tank body 100, and the sliding direction of the slotted opening and closing control plate 442 is also along the width direction of the sedimentation tank body 100. The inner rod of the opening and closing control driving rod 446 extends or retracts to drive the opening and closing control sliding cylinder 445 together with the slotted opening and closing control plate 442 to move along the axis direction of the opening and closing control fixed cylinder 444;

[0111] When the opening of the "slot mechanism channel" is small, the suspended particles in the high turbidity water will be more "crowded" when the high turbidity water flows through the "crowded flow channel". When the opening of the "slot mechanism channel" is large, part of the high turbidity water will overflow through the "slot mechanism channel" when the high turbidity water flows through the "crowded flow channel". At this time, the suspended particles in the high turbidity water will be less "crowded";

[0112] When high-turbidity water flows through the acoustic wave agglomeration mechanism 50, the acoustic wave generator 53 is used to intermittently generate ultrasonic waves of 22kHz, and the ultrasonic vibration energy is transmitted to the high-turbidity water through the transmission effect of the agglomeration mechanism housing shell 52. The ultrasonic vibration energy will form a specific energy field in the three-dimensional space. The ultrasonic vibration energy suspended particles vibrate together with the medium, and the suspended particles of different sizes have different relative vibration speeds, so the suspended particles will collide and bond with each other, so that the suspended particles are agglomerated with each other, and the volume and weight are increased. As the agglomerated suspended particles gradually become larger, they are inconvenient to vibrate with the ultrasonic vibration and can only do irregular movements. In this process, they continue to collide and bond, and finally the agglomerated suspended particles become larger and precipitate.

[0113] When high turbidity water flows through the linkage inclined plate sedimentation mechanism 30, the sedimentation area is increased due to the setting of the sedimentation barrier inclined plate 31, and the sedimentation distance of the suspended particles is shortened, thereby improving the sedimentation efficiency;

[0114] The inclination angles of the multiple sedimentation barrier inclined plates 31 can be adjusted in a linked manner.

[0115] The inclined plate driving motor 333 is a servo motor of the prior art. The output shaft of the inclined plate driving motor 333 drives the inclined plate driving shaft 331 to rotate through the meshing of the first active worm 334 and the first driven worm gear 332. The inclined plate driving shaft 331 drives the inclined plate supporting shaft 311 to deflect together with the sedimentation barrier inclined plate 31. The two adjacent sedimentation barrier inclined plates 31 are synchronously driven through the linkage driving connecting rod 32, so that the sedimentation barrier inclined plates 31 can be synchronously deflected around their respective inclined plate supporting shafts 311, thereby making the multiple sedimentation barrier inclined plates 31 always maintain a parallel state.

[0116] In the above series of processes, the suspended particles in the high turbidity water will settle and accumulate at the bottom of the sedimentation tank body 100, and each sedimentation interception slow flow baffle 15 can play a buffering and blocking effect to prevent the settled suspended particles from being disturbed by the water flow;

[0117] After the high turbidity water is treated by sedimentation, it forms clean water, which will overflow into the sedimentation tank outlet flow slot 161 through the sedimentation tank outlet flow slot 160, and finally be discharged from the outer end of the sedimentation tank outlet flow slot 161;

[0118] During the water discharge process, the water discharge filter 164 is used to perform auxiliary filtration on the clean water, which is beneficial to improving the water quality of the discharge water;

[0119] It is also capable of adjusting the inclination angle of each water outlet filter screen 164. The output shaft of the filter inclination drive motor 166 drives one of the water outlet filter support shafts 162 to rotate through gear transmission. The water outlet filter support shaft 162 then drives the remaining water outlet filter support shafts 162 to rotate synchronously through a synchronous belt transmission. The water outlet filter support shaft 162 drives the water outlet filter support plate 163 to deflect together with the water outlet filter screen 164, thereby adjusting the inclination angle of the water outlet filter screen 164, which is convenient for slag discharge and adjustment of the actual filtering effect of the water outlet filter screen 164.

[0120] The sedimentation backwashing mechanism 20 is used to centrally clean the suspended particles deposited at the bottom of the sedimentation tank body 100. The sliding drive motor 252 is a servo motor of the prior art. The output shaft of the sliding drive motor 252 drives the sliding drive screw 25 to rotate through gear transmission. Under the action of the screw transmission, the sliding drive screw 25 drives the sedimentation backwashing support block 21 to move along the width direction of the sedimentation tank body 100. The sedimentation backwashing support block 21 drives the sedimentation backwashing scraper 211 to move together. The sedimentation backwashing scraper 211 is used to push the suspended particles deposited at the bottom of the sedimentation tank body 100 to the backwashing outer discharge pipes 23 on both sides of the sedimentation tank body 100 in the width direction.

[0121] After all the suspended particles are accumulated at the backwashing outer discharge pipe 23, the outer discharge control valve 230 is opened. Driven by the impact of the water flow, the suspended particles accumulated at the backwashing outer discharge pipe 23 will be discharged together with the water flow through the backwashing outer discharge pipe 23, thereby preventing the suspended particles from accumulating too much at the bottom of the sedimentation tank body 100 and affecting the sedimentation efficiency of the sedimentation tank itself.

[0122] When all the water in the sedimentation tank body 100 is drained, clean water is delivered to the backwash delivery pipe 22 through a pipeline using a delivery pump in the prior art. Clean water is sprayed out from each backwash nozzle 220 to flush and clean the bottom of the sedimentation tank body 100. The backwash delivery pipe 22 can move with the sedimentation backwash scraper 211 to comprehensively clean the bottom of the sedimentation tank body 100.
