Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to an enhanced micro-vortex baffle flocculation reactor. Background Technology

[0002] Flocculation is one of the most core and commonly used processes in water treatment. Flocculation is divided into hydraulic flocculation and mechanical flocculation. Among hydraulic flocculation processes, baffle flocculation is the most widely used. Baffle flocculation utilizes multiple sets of baffles installed in the tank to create vortices in the water flow, creating a turbulent flow state to achieve particle collision and floc growth. Baffle flocculation has advantages such as good flocculation effect, short flocculation time, and small footprint.

[0003] In engineering, the average G-value of the flocculation tank, calculated using Camp theory and formulas, is generally used to characterize the turbulence intensity of the water flow in the flocculation tank. However, the average G-value only represents the spatial average energy dissipation rate and cannot reflect the local energy dissipation rate of the flow field. Modern flocculation theory proposes using the vortex G-value instead of the average G-value to more accurately characterize the flocculation effect. Kolmgoroff's micro-vortex theory suggests that the larger the vortex G-value, the smaller the vortex size generated in the fluid; conversely, the smaller the vortex G-value, the larger the vortex size generated. When the vortex size is close to the floc size, the flocculation reaction is most complete and the flocculation effect is optimal. When the vortex size exceeds this value, the turbulence of the water flow is insufficient to provide the energy required for flocculation. Conversely, when the vortex size is below this value, excessive water flow shear force will shear and break up the flocs.

[0004] Studies have shown that the initial and later sizes of flocs are both around 1×10⁻⁶. -5 m and 6×10 -4 The vortex size of the flocculation tank is approximately 1 × 10 m, meaning the vortex size ranges from 1 × 10 m. -5 m gradually increases to 6×10 -4 The flocculation effect is best at m. Hydraulic flow field simulation analysis of the relatively bent plate section and the parallel bent plate section of a traditional baffle flocculation tank shows that the vortex scale of both sections is basically concentrated at 1×10⁻⁶. -4 Up to 2×10 -4 Between m and m, the vortex size is relatively large compared to the initial size of the flocs, which has limited effect on improving the efficiency and effectiveness of the initial flocculation reaction.

[0005] To address the issue of large vortex sizes in folded plate flocculation tanks, Chinese Patent Publication No. CN220300488U discloses a "folded plate flocculation tank," comprising a front section, a middle section, and a rear section. A corrugated plate with varying degrees of wave pattern is arranged in the front section, a corrugated plate with uniform wave pattern is arranged in the middle section, and a straight plate is arranged in the rear section. At least one rhomboid-shaped turbulence column is arranged within the first flow channel between the corrugated plates. The corrugated plates often create large vortices in water; large vortices have lower flocculation intensity than smaller vortices. By placing turbulence columns between the corrugated plates, smaller vortices are provided, which work together with the larger vortices formed by the corrugated plates to improve flocculation intensity and effectiveness. However, since the cross-sectional size of the turbulence column is several orders of magnitude larger than the size of the flocs, the micro-vortex scale generated by the turbulence column will be much larger than the floc scale. Moreover, since there are only a few turbulence columns, the number of vortices generated is also relatively small. Therefore, from a microscopic perspective, the number of effective vortices generated by the turbulence column on the water flow is not large, the vortex intensity is not high, and the effect on promoting the collision and coagulation of micro flocs is not obvious, thus having a limited effect on improving the overall flocculation effect. Utility Model Content

[0006] The purpose of this invention is to provide an enhanced micro-vortex baffle flocculation reactor to solve the technical problems in existing flocculation reactors, such as excessively large vortex size, failure to meet the requirements for floc growth, insufficient number of effective micro-vortices, and poor flocculation efficiency and effect. The specific technical solution is as follows:

[0007] This utility model provides an enhanced micro-vortex baffle flocculation reactor, including a reactor body, multiple opposing baffles, multiple parallel baffles, multiple straight plates, and multiple enhanced micro-vortex flocculation devices. The reactor body has an S-shaped water channel, in which multiple opposing baffles, multiple parallel baffles, and multiple straight plates are arranged sequentially along the water flow direction. The enhanced micro-vortex flocculation device is arranged between two adjacent opposing baffles and between two adjacent parallel baffles.

[0008] A further improvement of this utility model of enhanced micro vortex baffle flocculation reactor is that multiple opposing baffles are respectively fixed to the top and bottom surfaces of the reactor body, and the rear sections of the opposing baffles all face the interior of the reactor body. The rear sections of the opposing baffles are provided with a first serrated section, and the serrations of the first serrated sections of two adjacent opposing baffles are arranged opposite each other. The enhanced micro vortex flocculation device is installed between the first serrated sections of two adjacent opposing baffles.

[0009] A further improvement of this utility model of enhanced micro vortex baffle flocculation reactor is that multiple parallel baffles are respectively fixed to the top and bottom surfaces of the reactor body, and the rear sections of the parallel baffles all face the interior of the reactor body. The rear sections of the parallel baffles are provided with a second serrated section, and the serrations of the second serrated sections of two adjacent parallel baffles are arranged in parallel. The enhanced micro vortex flocculation device is installed between the second serrated sections of two adjacent parallel baffles.

[0010] A further improvement of this utility model of enhanced micro-vortex baffle flocculation reactor is that the bottom of the reactor body is provided with a mud hopper and a mud discharge pipe system, and the mud hopper is connected to the mud discharge pipe system.

[0011] A further improvement of this utility model of enhanced micro vortex baffle flocculation reactor is that the reactor body is provided with an inlet, an outlet and an outlet channel. The inlet is located at the beginning of the water path, the outlet is located at the end of the water path, and the outlet is connected to the outlet channel.

[0012] A further improvement of this utility model of enhanced micro-vortex baffle flocculation reactor is that the enhanced micro-vortex flocculation device includes a top micro-vortex plate, a middle micro-vortex plate, a bottom micro-vortex plate and a support frame. The top micro-vortex plate is fixed to the top surface of the support frame, the middle micro-vortex plate is fixed to the middle part of the support frame, and the bottom micro-vortex plate is fixed to the bottom of the support frame. Multiple micro-vortex forming holes are provided on the top micro-vortex plate, the middle micro-vortex plate and the bottom micro-vortex plate.

[0013] A further improvement of this invention, the enhanced micro-vortex baffle flocculation reactor, is that the aperture of the micro-vortex forming hole of the enhanced micro-vortex flocculation device at the opposite baffle is smaller than the aperture of the micro-vortex forming hole of the enhanced micro-vortex flocculation device at the parallel baffle.

[0014] A further improvement of this utility model of enhanced micro-vortex baffle flocculation reactor is that the water channel includes a first section, a second section, a third section and a fourth section, multiple opposing baffles are installed in the first section and the second section, and multiple parallel baffles are installed in the third section and the fourth section.

[0015] A further improvement of this utility model of enhanced micro-vortex baffle flocculation reactor is that the aperture of the micro-vortex forming hole of the enhanced micro-vortex flocculation device in the first section is smaller than the aperture of the micro-vortex forming hole of the enhanced micro-vortex flocculation device in the second section.

[0016] A further improvement of this invention, the enhanced micro-vortex baffle flocculation reactor, is that the aperture of the micro-vortex forming hole in the third section of the enhanced micro-vortex flocculation device is smaller than the aperture of the micro-vortex forming hole in the fourth section of the enhanced micro-vortex flocculation device.

[0017] The application of the technical solution of this utility model has the following beneficial effects:

[0018] (1) The enhanced micro vortex baffle plate flocculation reactor of this utility model combines baffle plates with enhanced micro vortex flocculation device, which can make the reactor produce a comprehensive effect of deflection, swirling and micro vortex on the internal water flow. The deflection effect causes the flocs in the water to collide and contact initially. Its effect range is narrow and the effect frequency is low. Then, through the swirling effect generated by the continuous expansion and contraction of the baffle plate, the flocs quickly aggregate and grow. Its effect range is wide and the effect frequency is high. Finally, the micro vortex effect generated by the enhanced micro vortex flocculation device increases the turbulence intensity of the water flow, providing sufficient reaction power for floc collision, aggregation and growth. At the same time, the large number of micro vortices generated can promote the collision and aggregation of the remaining small flocs in the water, increase the capture rate of small flocs and the utilization rate of coagulant. This invention enhances the combined effects of baffles, swirls, and micro-vortices provided by the micro-vortex baffle flocculation reactor, which can significantly improve the reaction dynamics of flocculation, increase the intensity of water flow turbulence, take into account the flocculation of flocs of various sizes, improve the flocculation reaction effect and efficiency, reduce the amount of coagulant added, and shorten the flocculation reaction time.

[0019] (2) Setting up enhanced micro-vortex flocculation devices with smaller pore size and opening ratio in the relatively folded plate section and enhanced micro-vortex flocculation devices with larger pore size and opening ratio in the parallel folded plate section can form micro-vortices with relatively small scale, relatively large turbulent energy and relatively strong disturbance in the relatively folded plate section and micro-vortices with relatively large scale, relatively small turbulent energy and relatively weak disturbance in the parallel folded plate section. This provides the best flocculation hydraulic conditions for each flocculation stage, maximizes the fit with the microscopic mechanism of floc growth, can greatly improve the flocculation reaction efficiency and effect, reduce flocculation time and reduce the amount of flocculant added.

[0020] (3) Because the apertures of the micro-vortex forming holes inside the enhanced micro-vortex flocculation device are the same, micro-vortices of basically consistent size can be formed, increasing the number of micro-vortices that can effectively promote the flocculation reaction. In addition, an increased velocity gradient is created inside the device to form a gradient of turbulence intensity, providing sufficient reaction power for the gradually growing flocs and increasing the probability of floc collision.

[0021] (4) The enhanced micro vortex flocculation reactor has good flocculation effect and high reaction efficiency. The baffle plate and the enhanced micro vortex flocculation device are provided as a set and can be adapted to reactors of various sizes. It is easy to install on site, and the reactor is not prone to sludge accumulation and blockage in various parts, and the workload of inspection and maintenance is small.

[0022] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0041] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0042] See Figures 1 to 16 As shown, an enhanced micro-vortex baffle flocculation reactor includes a reactor body 1, multiple opposing baffles 3, multiple parallel baffles 4, multiple straight plates 5, and multiple enhanced micro-vortex flocculation devices 6. The reactor body 1 has an S-shaped water channel, in which multiple opposing baffles 3, multiple parallel baffles 4, and multiple straight plates 5 are arranged sequentially along the water flow direction. The enhanced micro-vortex flocculation device 6 is arranged between two adjacent opposing baffles 3 and between two adjacent parallel baffles 4.

[0043] like Figure 1As shown, the reactor body 1 is divided into an S-shaped water channel by multiple partition walls 12, and each partition wall 12 has a water passage hole 11 for water flow. This invention, through a specific arrangement of relative folding plates 3, parallel folding plates 4, and straight plates 5, divides the interior of the reactor body 1 into multiple vertical or horizontal flow channels. Water flows through these channels, and under the influence of the folding plates of a certain shape, vortices are generated in the water flow to increase particle collision and promote floc growth.

[0044] Preferred, such as Figure 2 As shown, multiple opposing folding plates 3 are respectively fixed to the top and bottom surfaces of the reactor body 1, with the rear sections of each opposing folding plate 3 facing inwards towards the reactor body 1. Each rear section of the opposing folding plate 3 is provided with a first serrated segment, and the serrations of the first serrated segments of adjacent opposing folding plates 3 are arranged opposite each other. The enhanced micro-vortex flocculation device 6 is installed between the first serrated segments of adjacent opposing folding plates 3. The number of opposing folding plates 3 and the enhanced micro-vortex flocculation device 6 is set according to actual needs. In this embodiment, the area where the opposing folding plates 3 are set includes a first section and a second section, with the same number in both sections, and the components are symmetrically arranged. The first section contains five opposing folding plates 3, evenly spaced, with three fixed to the top surface of the reactor body 1 and two fixed to the bottom surface, thereby blocking and forming an S-shaped water flow path. The enhanced micro-vortex flocculation device 6 is divided into four groups. One group of enhanced micro-vortex flocculation devices 6 is installed between two adjacent relative baffles 3. Each group contains two enhanced micro-vortex flocculation devices 6. The two enhanced micro-vortex flocculation devices 6 are spaced apart and inclined between two adjacent relative baffles 3 and are installed on the inner wall of the reactor body 1.

[0045] Preferred, such as Figure 3As shown, multiple parallel folding plates 4 are respectively fixed to the top and bottom surfaces of the reactor body 1, and the rear sections of the parallel folding plates 4 all face inward towards the interior of the reactor body 1. Each rear section of the parallel folding plate 4 is provided with a second serrated segment, and the serrations of the second serrated segments of adjacent parallel folding plates 4 are arranged parallel to each other. The enhanced micro-vortex flocculation device 6 is installed between the second serrated segments of adjacent parallel folding plates 4. The number of parallel folding plates 4 and the enhanced micro-vortex flocculation device 6 is set according to actual needs. In this embodiment, the areas where the parallel folding plates 4 are set include the third and fourth sections, with the same number in the third and fourth sections, and the components are symmetrically arranged. The third section contains five parallel folding plates 4, which are evenly spaced, with three fixed to the top surface of the reactor body 1 and two fixed to the bottom surface, thereby blocking and forming an S-shaped water flow path. The enhanced micro-vortex flocculation device 6 is divided into four groups. One group of enhanced micro-vortex flocculation devices 6 is installed between two adjacent parallel baffles 4. Each group contains two enhanced micro-vortex flocculation devices 6. The two enhanced micro-vortex flocculation devices 6 are spaced apart and inclined between two adjacent parallel baffles 4, and are installed on the inner wall of the reactor body 1.

[0046] Preferably, the bottom of the reactor body 1 is provided with a mud hopper 7 and a mud discharge pipe system 8, the mud hopper 7 being connected to the mud discharge pipe system 8. The mud hopper 7 and the mud discharge pipe system 8 are used to collect and discharge flocculent particles deposited at the bottom of the tank.

[0047] Preferred, such as Figure 1 As shown, the reactor body 1 has an inlet 2, an outlet 9, and an outlet channel 10. The inlet 2 is located at the beginning of the water path, and the outlet 9 is located at the end of the water path, connected to the outlet channel 10. The inlet 2 is connected to the beginning of the opposing baffle 3 section, and the outlet 9 is connected to the end of the straight plate 5 section and the outlet channel 10. The outlet channel 10 is used to connect the effluent from the flocculation tank and the influent to the subsequent sedimentation tank, so that the water flows into the sedimentation tank as evenly and stably as possible.

[0048] Preferred, such as Figures 4 to 16As shown, the enhanced micro-vortex flocculation device 6 includes a top micro-vortex plate 601, a middle micro-vortex plate 602, a bottom micro-vortex plate 603, and a support frame 605. The top micro-vortex plate 601 is fixed to the top surface of the support frame 605, the middle micro-vortex plate 602 is fixed to the middle of the support frame 605, and the bottom micro-vortex plate 603 is fixed to the bottom of the support frame 605. Multiple micro-vortex forming holes 604 are provided on each of the top, middle, and bottom micro-vortex plates 601, 602, and 603. Specifically, the support frame 605 is composed of multiple support tubes. Each micro-vortex plate has a micro-vortex forming hole 604, which is circular or a regular polygon. The regular polygon has at least four sides, and the diameter of the inscribed circle of the circular or regular polygonal hole is 50–150 mm. The vortex-forming holes are uniformly arranged on the micro-vortex plates. Adjacent rows of micro-vortex-forming holes 604 on the same micro-vortex plate are staggered, and the micro-vortex-forming holes 604 on adjacent micro-vortex plates are staggered in the water flow direction. This allows the water flow to continuously change its velocity vector as it passes through each micro-vortex plate, increasing the probability of particle collision. The enhanced micro-vortex flocculation device 6 is generally composed of 3 to 5 of the aforementioned micro-vortex plates arranged in parallel. The spacing between adjacent micro-vortex plates is the same, generally 75 to 150 mm. Adjacent micro-vortex plates are fixed together by support tubes with a length equal to the designed plate spacing. The diameter of the support tubes is φ15 to 20 mm, and the support tubes are arranged around and inside the micro-vortex plates. This arrangement, while fixing the micro-vortex plates, prevents deformation due to excessive plate area. All components in this enhanced micro-vortex flocculation device 6 are made of carbon steel or stainless steel, and the micro-vortex plates and support tubes can be welded together.

[0049] The top micro-vortex plate 601, the middle micro-vortex plate 602, and the bottom micro-vortex plate 603 are arranged in parallel with a spacing of 100mm. Adjacent micro-vortex plates are fixed by a support frame 605, which includes twelve support tubes with a diameter of φ20mm. These support tubes are arranged around and in the center of the micro-vortex plates to securely connect the three plates. The top micro-vortex plate 601 and the bottom micro-vortex plate 603 extend outwards by 100mm in their width direction as extension plates 606. Four bolt holes 607 with a diameter of φ12~20mm are evenly provided on each extension plate 606. The two extension plates 606 at both ends of the same vortex plate are bent 90° in the same direction along the bending line. Figure 5 As shown, each enhanced micro vortex flocculation device 6 has four extension plates 606 on its top micro vortex plate 601 and bottom micro vortex plate 603, which are bent 90° along line A. The enhanced micro vortex flocculation device 6 is fixed to the tank wall of the reactor body 1 at a 45° angle by these four extension plates 606 and corresponding expansion bolts.

[0050] Preferably, the aperture of the micro-vortex forming hole 604 of the enhanced micro-vortex flocculation device 6 at the relative folding plate 3 is smaller than the aperture of the micro-vortex forming hole 604 of the enhanced micro-vortex flocculation device 6 at the parallel folding plate 4.

[0051] Preferably, the waterway includes a first section, a second section, a third section, and a fourth section, with multiple opposing folding plates 3 installed in the first and second sections, and multiple parallel folding plates 4 installed in the third and fourth sections.

[0052] Preferably, the aperture of the micro-vortex forming hole 604 of the enhanced micro-vortex flocculation device in the first section is smaller than the aperture of the micro-vortex forming hole 604 of the enhanced micro-vortex flocculation device 6 in the second section.

[0053] Preferably, the aperture of the micro-vortex forming hole 604 of the enhanced micro-vortex flocculation device in the third section is smaller than the aperture of the micro-vortex forming hole 604 of the enhanced micro-vortex flocculation device 6 in the fourth section.

[0054] Within the same enhanced micro-vortex flocculation device 6, the micro-vortex forming holes 604 on each micro-vortex plate have the same diameter, so as to form micro-vortices of basically uniform size inside the device, thereby increasing the proportion of micro-vortices that can promote flocculation. Furthermore, the number of openings on the micro-vortex plates decreases sequentially along the water flow direction, the opening ratio gradually decreases, and the water flow through-hole velocity gradually increases, creating a growing velocity gradient to form a gradient of turbulence intensity, providing sufficient reaction power for the gradually growing flocs.

[0055] Simultaneously, enhanced micro-vortex flocculation devices 6 with different pore sizes and opening ratios are set in the three sections of the relative baffle plate and the four sections of the parallel baffle plate. Considering the dimensions of the flow channels in the baffle plate flocculation reactor, the pore size of the enhanced micro-vortex flocculation device 6 in the three sections of the relative baffle plate should be 50–100 mm, and the average opening ratio should be 30%–50%. The pore size of the enhanced micro-vortex flocculation device 6 in the four sections of the parallel baffle plate should be 100–150 mm, and the average opening ratio should be 50%–70%. Through the specific arrangement of different pore sizes and opening ratios, relatively small-scale micro-vortices with relatively large turbulent energy can be formed in the three sections of the relative baffle plate, while relatively large-scale micro-vortices with relatively small turbulent energy can be formed in the four sections of the parallel baffle plate. This allows for the control of vortex scale at the microscopic mechanism level of floc growth, creating ideal hydraulic conditions for the flocculation reaction at each stage.

[0056] Furthermore, the multiple sets of enhanced micro-vortex flocculation devices 6 arranged within the three-section relative folded plate or the four-section parallel folded plate can also be arranged in a progressively increasing manner, with the aperture of the micro-vortex forming holes 604 and the opening ratio of the micro-vortex plates. For example, within the three-section relative folded plate, the aperture of the devices can be subdivided into five specifications of 50, 60, 70, 80, and 90 mm along the water flow direction, based on the number of enhanced micro-vortex flocculation devices 6 in this reaction stage, with the corresponding average opening ratios subdivided into 30%, 35%, 40%, 45%, and 50%. Within the four-section parallel folded plate, the aperture of the devices can be subdivided into five specifications of 100, 110, 120, 130, and 140 mm along the water flow direction, based on the number of enhanced micro-vortex flocculation devices 6 in this reaction stage, with the corresponding average opening ratios subdivided into 50%, 55%, 60%, 65%, and 70%. The specific number of subdivision levels and the parameters of each level should be determined based on the scale and size analysis of the flocculation reactor. The more subdivision levels there are, the larger the scale of the generated micro vortices will be, and the more obvious the promoting effect on the flocculation reaction will be.

[0057] In this embodiment, the reactor body 1 is equipped with enhanced micro-vortex flocculation devices 6 with different pore sizes and average opening ratios in the relative baffle section and the parallel baffle section. Relative baffles are provided on the first and second sections, with four sets of type A enhanced micro-vortex flocculation devices 6 installed in the relative baffle section of the first section. Figures 5-7 As shown, the micro-vortex forming holes 604 on the vortex plate all have a diameter of φ60mm. Along the water flow direction, the top micro-vortex plate 601 has 114 holes evenly distributed, with an opening rate of approximately 35%; the middle micro-vortex plate 602 has 105 holes evenly distributed, with an opening rate of approximately 30%; and the bottom micro-vortex plate 603 has 95 holes evenly distributed, with an opening rate of approximately 25%. The average opening rate of the type A enhanced micro-vortex flocculation device 6 is 30%. Figures 8-10 As shown, the second section relative to the folded plate section is equipped with four sets of type B enhanced micro vortex flocculation devices 6. The diameter of the micro vortex forming holes 604 opened on the vortex plate is φ80mm. In the direction of water flow, the top micro vortex plate 601 has 86 holes evenly opened, with an opening rate of about 45%; the middle micro vortex plate 602 has 76 holes evenly opened, with an opening rate of about 40%; and the bottom micro vortex plate 603 has 67 holes evenly opened, with an opening rate of about 35%. The average opening rate of the type B enhanced micro vortex flocculation device 6 is 40%.

[0058] Within the same folding plate reaction section, the enhanced micro-vortex flocculation device 6 has micro-vortex forming holes 604 with the same diameter, which can form micro-vortices of basically uniform size. By controlling the hole size, it is beneficial to increase the number of effective micro-vortices. In each set of enhanced micro-vortex flocculation devices 6, the number of micro-vortex forming holes 604 along the water flow direction gradually decreases, and the opening ratio gradually decreases. When the water flows through the enhanced micro-vortex flocculation device 6, the flow velocity gradually increases, forming a gradually increasing turbulence intensity gradient, providing sufficient reaction power for the gradually growing flocs, and improving the floc collision and flocculation reaction efficiency.

[0059] This embodiment includes two parallel folded plate sections. The third parallel folded plate section is equipped with four sets of C-shaped enhanced micro-vortex flocculation devices (6 in total). Figures 11-13 As shown, the micro-vortex forming holes 604 on the vortex plate all have a diameter of φ100mm. Along the water flow direction, the top micro-vortex plate 601 has 67 holes evenly spaced, with an opening rate of approximately 55%; the middle micro-vortex plate 602 has 57 holes evenly spaced, with an opening rate of approximately 50%; and the bottom micro-vortex plate 603 has 48 holes evenly spaced, with an opening rate of approximately 45%. The average opening rate of the C-type enhanced micro-vortex flocculation device 6 is 50%. Figures 14-16 As shown, the fourth section relative to the folded plate section is equipped with four sets of D-type enhanced micro-vortex flocculation devices 6. The diameter of the micro-vortex forming holes 604 opened on the vortex plate is φ120mm. In the direction of water flow, the top micro-vortex plate 601 has 57 holes evenly opened, with an opening rate of about 65%; the middle micro-vortex plate 602 has 48 holes evenly opened, with an opening rate of about 60%; and the bottom micro-vortex plate 603 has 38 holes evenly opened, with an opening rate of about 55%. The average opening rate of the D-type enhanced micro-vortex flocculation device 6 is 60%.

[0060] In this embodiment, the aperture and porosity of the enhanced micro-vortex flocculation device 6, which is set along the water flow direction in the relatively folded plate section and the parallel folded plate section, gradually increase. This allows for the formation of micro-vortices with relatively small scale and relatively large turbulent energy in the relatively folded plate section, and relatively large scale and relatively small turbulent energy in the parallel folded plate section. This provides optimal flocculation hydraulic conditions for each flocculation stage, maximally matches the microscopic mechanism of floc growth, significantly improves flocculation reaction efficiency and effect, reduces flocculation time, and lowers the amount of flocculant added.
