Description

Technical Field

[0001] The present invention relates to the technical field of water treatment in water plants, and in particular to a new system capable of timely adjusting and realizing efficient water quality treatment in water plants according to water inlet dynamics, especially a system realizing comprehensive water quality treatment in water plants based on water inlet dynamics. Background Art

[0002] The quality of water treatment processes at water plants directly determines the quality of the water at the end of treatment. Current industrial water plants generally use wastewater sedimentation, filtration, hydrolysis and acidification, secondary sedimentation tanks, fine filtration, and discharge processes to treat wastewater.

[0003] There are many wastewater treatment technologies in the prior art. For example, a wastewater treatment method and treatment system are disclosed in the patent document with patent application number CN201310162735.X, and its main steps include: step one: filtering to remove impurities in the water; step two: using the anaerobic-anoxic-aerobic AAO method to denitrify and dephosphorize the filtered water and remove organic matter; step three: using the membrane bioreactor MBR method to treat the water obtained in step two, for intercepting, degrading and filtering the activated sludge and macromolecular substances in the water; step four: using chlorine dioxide to perform online oxidation and disinfection on the water obtained in step three.

[0004] It can be seen from the contents recorded in the patent literature of the above-mentioned wastewater treatment method and treatment system that the patent mainly involves filtering the wastewater in sequence, removing nitrogen and phosphorus, removing organic matter, and intercepting activated sludge and macromolecular substances in the water body. This treatment process still remains at the traditional water treatment process, with poor water quality treatment effect and inability to effectively monitor the treatment effect. The treatment methods in each process are relatively conventional, which makes it difficult to achieve good treatment effects when using the above-mentioned technology to treat wastewater, especially when treating pollutants or industrial wastewater with high concentrations.

[0005] For another example, a multi-stage wastewater treatment system is also disclosed in the patent document with patent application number CN201910985681.4, whose main structure includes a regulating tank for regulating water volume and water quality, a primary sedimentation tank for preliminary sedimentation, an anaerobic tank for treating wastewater using anaerobic technology, an aerobic tank using aeration and oxygenation technology to promote wastewater treatment, a secondary sedimentation tank for secondary sedimentation and separation of mud and water, a clear water tank for storing treated clear water, a floating balanced water supply mechanism that can reduce water impact and facilitate sedimentation, an anaerobic mixing mechanism for mixing mud and water under anaerobic conditions to promote wastewater treatment, and an active oxygenation mechanism for aeration and oxygenation. The primary sedimentation tank and the secondary sedimentation tank are both provided with a floating balanced water supply mechanism, the anaerobic mixing mechanism is provided on the anaerobic tank, and the active oxygenation mechanism is provided on the aerobic tank.

[0006] It can be seen from the above-mentioned multi-stage wastewater treatment system that the patent document mainly performs multi-stage treatment in the traditional wastewater treatment process, but in the treatment process, it still utilizes the traditional regulating tank, primary sedimentation tank, anaerobic tank, aerobic tank, and secondary sedimentation tank stacked in series. It has increased the treatment links as a whole, but there is no obvious improvement in the treatment process of each step. At the same time, its treatment effect on water quality cannot be effectively monitored. The overall water quality treatment can be improved to a certain extent due to the increase in processes, but the rationality of the overall water treatment is still poor.

[0007] To this end, the present invention proposes a new system that can adjust in time according to the water inlet dynamics and achieve efficient water quality treatment in the water plant, so as to solve the problems existing in the prior art. Summary of the Invention

[0046] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only used as examples and are not intended to limit the scope of protection of the present invention. Figure 1-7 As shown in .

[0047] Example 1:

[0048] A system for achieving comprehensive water quality treatment in a water plant based on the dynamics of water inlet comprises an oil-separating filter residue unit a, the water inlet end of the oil-separating filter residue unit a being connected to a wastewater source end 1, a comprehensive regulation unit b being connected downstream of the oil-separating filter residue unit a, the comprehensive regulation unit b being used for achieving dosing regulation of the wastewater treated by the oil-separating filter residue unit a, a sedimentation tank 2 being connected downstream of the comprehensive regulation unit b, a multi-stage water quality membrane filtration purification unit 3 being connected downstream of the sedimentation tank 2, an industrial water end 4 and a domestic water deep treatment end 5 being connected downstream of the multi-stage water quality membrane filtration purification unit 3, the concentrated wastewater and residue-containing wastewater discharged from the wastewater outlet end of each unit being introduced into an external sludge treatment process, a water flow sensor 6 being installed on the water inlet end of the oil-separating filter residue unit a, the water flow sensor 6 being connected to the water plant control end signal and feeding back the dynamic water flow signal to the water plant control end.

[0049] The system for realizing comprehensive water quality treatment of the water plant based on the dynamics of water inflow can use the water flow sensor 6 to monitor the incoming wastewater flow in real time, and at the same time feed back to the water plant control end to realize the purpose of artificially regulating each unit of the system, and adjusting on demand to achieve better energy saving.

[0050] The wastewater entering this system will first pass through the water inlet end of the oil-separating filter residue unit a and enter the oil-separating filter residue unit a. The water flow set here enters from the lower part of the oil-separating filter residue unit a, and then the liquid level is raised upward in the middle. The wastewater is deoiled and filtered in the oil-separating filter residue unit a and then sent to the downstream comprehensive regulation unit b. Bacteria, drugs and reagents are added to the comprehensive regulation unit b, and sufficient and rapid mixing is achieved in the comprehensive multi-stage mixing component to ensure the uniformity of the mixing. The pollutants in the water after the regulation treatment are greatly reduced, and then continue to be treated in the multi-stage water quality membrane filtration purification unit 3 to meet the standards for domestic and industrial use. Similarly, the muddy wastewater and residue-containing wastewater generated at the end of each unit will be transported to the external sludge treatment process for sludge purification and drying. In order to ensure that the water quality of each link meets the standards, a water quality sampler 20 is also installed in each unit in this system. The water quality sampler 20 takes out the water sample and sends it to the outside for testing. After passing the test, it enters the next process, ensuring the water quality treatment effect.

[0051] In any of the above schemes, it is preferred that the oil-separating filter residue unit a includes a wastewater source tank 7, and a water inlet pipe 9 with a one-way water inlet valve 8 is installed at the lower part of one side wall of the wastewater source tank 7. The water inlet pipe 9 is used to receive the wastewater source water from the upstream wastewater source 1. A floating oil outlet mechanism c is installed on the left side of the wastewater source tank 7. The floating oil outlet mechanism c is used to outlet the oil floating on the surface of the wastewater in the wastewater source tank 7. The wastewater source water above the water inlet pipe 9 is A horizontally arranged blocking filter residue net 10 is detachably fixedly installed inside the water storage chamber 701 of the pool 7. The blocking filter residue net 10 is used to block impurities and residues in the wastewater in the water storage chamber 701 below it. A residue net cleaning assembly is installed on the rear side of the water storage chamber 701. The residue net cleaning assembly is used to move back and forth along the front and rear directions of the water storage chamber 701 and clean the upper and lower surfaces of the blocking filter residue net 10; the water flow sensor 6 is installed in the water inlet pipe 9.

[0052] When the oil-separating filter residue unit a is working, the wastewater entering the wastewater source pool 7 flows in from the water inlet pipe 9 at its bottom at a certain pressure and flow rate. Therefore, as the water flow continues to increase, the wastewater will increase upward. When encountering the blocking filter residue net 10, the larger residue cannot continue to move upward, and at this time it will play a role in blocking and filtering the residue.

[0053] Here, the water inlet pipe port 9 is set below the barrier filter residue net 10 mainly to achieve filter residue floating on the liquid surface, which is different from the traditional downward flow filter residue method, and it mainly has three functions: first, this upward filter residue method can better block the upward movement of the residue, and at the same time, slow filter residue is achieved as the water liquid level rises, and the residue that can be filtered out is better accumulated at the bottom; second, the residue is located at the bottom and is blocked by the barrier filter residue net 10, so that it will not interfere with the treatment of the supernatant on the top, which is convenient for the later start-up of floating oil treatment and outward oil diversion operations; third, when the water on the upper part of the barrier filter residue net 10 is drained out, the residue-containing wastewater accumulated at the lower part of the barrier filter residue net 10 can be easily cleaned and directly discharged from the bottom, with good cleaning effect. When cleaning, quick cleaning can be achieved by directly impacting the upper part of the barrier filter residue net 10 with water with a certain pressure, and the barrier filter residue net 10 does not need to be taken out for cleaning.

[0054] In any of the above schemes, it is preferred that the floating oil outlet mechanism c includes a square bin 11 fixedly and sealingly installed on the left side wall of the wastewater source tank 7, the inner wall of the inner cavity of the square bin 11 and the outer wall of the wastewater source tank 7 at the corresponding position are both polished metal smooth surfaces, and a push-block sealing plug plate 12 is sealed and inserted in the inner cavity of the square bin 11, and a lifting control cylinder 13 is fixedly installed on the left outer wall of the wastewater source tank 7 below the square bin 11, the upper part of the piston rod of the lifting control cylinder 13 is movably extended into the inner cavity of the square bin 11 and is fixedly connected to the bottom of the push-block sealing plug plate 12, in the square bin 11. Several adjustable oil guides d are installed at intervals along the height direction of the outer wall of the wastewater raw tank 7 on the left side of the inner cavity of the bin 11. Each of the adjustable oil guides d is in a normally open state when in a free state. An oil discharge port 14 is provided on the left side wall of the square bin 11 opposite to each of the adjustable oil guides d. A floating oil outlet pipe 15 with a control valve connected to the oil discharge port 14 is fixedly installed on the side wall of the square bin 11 on the left side of the oil discharge port 14. The bottom outlet of the floating oil outlet pipe 15 is used to discharge an oil-water mixture containing floating oil. The bottom of the oil discharge port 14 is lower than the lowest adjustable oil guide d.

[0055] When the push-sealing plug plate 12 moves upward, it pushes the corresponding adjustable oil guide d to the right in sequence to convert it into a sealed closed state.

[0056] Before the floating oil outlet mechanism c is used to guide the oil inside the wastewater source tank 7, the lifting control cylinder 13 on it drives the top push sealing plug plate 12 to move to the high position. At this time, under the action of the push sealing plug plate 12, each adjustable oil guide d will be abutted and each adjustable oil guide d will be in a closed state. At this time, the upper layer of water inside the wastewater source tank 7 will not flow out through the various adjustable oil guides d. At this time, the air flotation drainage combination mechanism can be started to supply pulse airflow to the wastewater inside the wastewater source tank 7 to achieve air flotation treatment. With the air flotation treatment, the wastewater inside the water storage chamber can be continuously pneumatically stirred, thereby achieving the purpose of using bubbles to drive the internal oil to float out. When the wastewater is left to stand, the oil floats Floating on the upper layer, at this time, the push-block sealing plug plate 12 is controlled to move slowly downward, and the number of open adjustable oil guides d is controlled according to the thickness of the oil. When the adjustable oil guide d breaks away from the left side pressure of the push-block sealing plug plate 12, it will be reset and opened under the action of the reset spring 19. At this time, the oil layer mixture flows out through the channel on the corresponding adjustable oil guide d and flows to the oil discharge port 14, and finally is discharged to the outside through the floating oil outlet pipe 15, thereby achieving preliminary removal of floating oil. This can achieve standard treatment of floating oil for wastewater with a low floating oil content; when the oil content in the wastewater is high, the wastewater oil removal equipment 30 can be started again to finely remove the oil, and finally achieve the purpose of meeting the standard of oil content.

[0057] In any of the above schemes, it is preferred that the adjustable oil guide d includes a T-shaped stepped through hole 16 arranged on the outer wall of the wastewater raw tank 7 on the left side of the square bin 11, the T-shaped stepped through hole 16 is horizontally arranged and the inner diameter on the left side is larger than the inner diameter on the right side, a stepped plug shaft 17 is coaxially installed in the T-shaped stepped through hole 16, the right outer diameter of the stepped plug shaft 17 is smaller than its left outer diameter and the left outer diameter matches the right inner diameter of the T-shaped stepped through hole 16, a spherical segment 18 is installed on the left end face of the stepped plug shaft 17, and a return spring 19 is sleeved on the outer wall of the stepped plug shaft 17 between the spherical segment 18 and the step surface of the T-shaped stepped through hole 16, and the two ends of the return spring 19 are respectively fixedly mounted on the spherical segment 18 and the step surface of the T-shaped stepped through hole 16, and the outer diameter of the spherical segment 18 matches the left major diameter of the T-shaped stepped through hole 16.

[0058] The multiple adjustable oil guides d designed in the present invention and located at different heights can realize opening of different numbers of adjustable oil guides d according to different oil layer thicknesses. When the adjustable oil guides d are opened, the oil inside the water storage chamber can flow out directly through the annular channels at the corresponding positions of each adjustable oil guide d, and finally achieve the purpose of discharging the upper oil-water mixture at the channel of the adjustable oil guide d at the upper part of the water storage chamber that is higher than the lowest position to the outside on the left side.

[0059] In the normal natural state, under the action of the return spring 19, the large-diameter section of the stepped plug shaft 17 is located on the left side of the T-shaped stepped through hole 16 and there is an annular channel between the stepped plug shaft 17 and the T-shaped stepped through hole 16, which can allow oil to flow out; when the oil is drained, the sealing plug plate 12 can be moved upward to push the spherical segments 18 of the three adjustable oil guides d of different heights to the right in turn and make the stepped plug shaft 17 block the T-shaped stepped through hole 16, thereby achieving blocking, effectively ensuring the smooth conversion between oil drainage and oil blocking.

[0060] In any of the above schemes, preferably, each unit is provided with a water quality sampler 20, and each of the water quality samplers 20 transports the water sample taken to the outside through a water sample transport pipe 21 to complete water sample testing;

[0061] The purpose of setting up water quality samplers 20 in each unit is to be able to conduct rapid sampling and testing for each process link to ensure that the water quality after treatment in each process meets the standards.

[0062] A flotation and drainage combination mechanism is installed on the upper right side of the wastewater source tank 7. The flotation and drainage combination mechanism completes two processes in the wastewater source tank 7: flotation treatment of the wastewater therein and transfer of the waste liquid after oil discharge. The output end of the flotation and drainage combination mechanism is connected to the inlet end of the downstream integrated regulation unit b through the post-filtration pipeline 22.

[0063] In any of the above schemes, it is preferred that the air flotation and liquid discharge combination mechanism includes a lifting and positioning cylinder group 23 fixedly installed on the right side outer wall of the wastewater raw pool 7, a lifting and positioning seat 24 is fixedly installed on the top of the piston rod of the lifting and positioning cylinder group 23, a vertical and hollow multi-purpose riser 25 is fixedly installed on the lifting and positioning seat 24, the bottom of the multi-purpose riser 25 is sealed, and the post-filtration pipeline 22 is connected to the top liquid outlet of the multi-purpose riser 25; the air inlet pipe on the upper outer wall of the multi-purpose riser 25 is connected to the external pulse air source through a pulse air pipe 26 with a control valve;

[0064] The water sampler 20 is installed on one side of the top liquid outlet of the multi-purpose standpipe 25. A valve is installed on the pipeline between the water sampler 20 and the top liquid outlet of the multi-purpose standpipe 25. The output port of the sampler transports the collected water sample to the outside through the water sample delivery pipe 21 to complete the water sample detection.

[0065] A horizontal lifting pipe 27 is connected and fixed to the left side of the lower part of the multi-purpose riser 25. The left end of the horizontal lifting pipe 27 is sealed and a plurality of gas-liquid dual-purpose holes 28 are evenly spaced on the surface of the horizontal lifting pipe 27. When in the wastewater flotation treatment process, each gas-liquid dual-purpose hole 28 is used to spray pulse airflow outward from the inside of the horizontal lifting pipe 27. When in the wastewater discharge and drainage process, each gas-liquid dual-purpose hole 28 is used to discharge the waste liquid in the water storage chamber above the blocking filter net 10 to the outside.

[0066] During the flotation process:

[0067] Before the oil and liquid inside the wastewater source tank 7 are discharged, the flotation and drainage combination mechanism can control the external air source to introduce high-pressure pulse gas into the multi-purpose riser 25 through the air inlet pipe. At this time, the top liquid outlet on the top of the multi-purpose riser 25 is in a closed state; after the high-pressure pulse gas enters the multi-purpose riser 25, it is discharged through the various gas-liquid dual-purpose holes 28 on the horizontal lifting pipe 27 to drive the wastewater to stir, and the internal oil and liquid will float to above the liquid surface under the action of bubbles. During the flotation treatment process, the lifting and lowering of the lifting and positioning cylinder group 23 can be controlled to drive the horizontal lifting pipe 27 to move up and down to spray air outward, and finally move up and down while being impacted by the flotation pneumatics, thereby improving the effect of the flotation treatment.

[0068] When the flotation process is completed, the air supply is controlled to stop, and the wastewater is then left to stand. At this time, the oil and water inside the water storage chamber will be separated into layers, and the floating oil outlet mechanism C can be controlled to operate to outlet the upper floating oil mixture.

[0069] During the drainage process:

[0070] When the floating oil is extracted, the control starts the lifting and positioning cylinder group 23 to drive the horizontal lifting pipe 27 to a suitable height for the wastewater supernatant. At this time, the horizontal lifting pipe 27 is always above the blocking filter residue net 10, and the water quality sampler 20 at the outlet is opened, and the water sample is sent for inspection. When the oil content of the water sample is unqualified, the valve and pump body on the post-filter pipeline 22 are closed, and then the wastewater oil removal equipment 30 on the fine oil removal bypass 29 is opened, so that the wastewater after the preliminary deoiling is further refined to remove the remaining oil, and finally enters the downstream process after passing this test; in addition, if the oil content of the wastewater is found to be up to standard after sampling by the water quality sampler 20 at the post-filter pipeline 22, there is no need to open the wastewater oil removal equipment 30. At this time, the valve and pump body on the post-filter pipeline 22 are directly opened, and the deoiled wastewater is finally sent to the interior of the comprehensive regulation unit b for further treatment.

[0071] In any of the above schemes, it is preferred that a fine oil removal bypass 29 is arranged in parallel on the post-filtration pipeline 22, a wastewater oil removal equipment 30 is installed on the fine oil removal bypass 29, and control valves are respectively installed on the fine oil removal bypass 29 connected to the inlet end and the water outlet end of the wastewater oil removal equipment 30; when the water taken out by the water quality sampler 20 at the multi-purpose riser 25 is detected by the external detection system, if the oil content exceeds the standard, the fine oil removal bypass 29 is started and the post-filtration pipeline 22 is blocked. At this time, the water discharged by the flotation and drainage combination mechanism will be processed through the fine oil removal bypass 29 and then discharged to the downstream comprehensive regulation unit b, and each pipeline is equipped with a corresponding power pump.

[0072] When it is necessary to discharge liquid to the post-filtration pipeline 22, the water quality sampler 20 at the outlet is opened and the water sample is sent for inspection. When the oil content of the water sample is unqualified, the valve and pump body on the post-filtration pipeline 22 are closed, and then the wastewater oil removal equipment 30 on the fine oil removal bypass 29 is opened, so that the wastewater after the initial deoiling is refined again to remove the remaining oil, and finally enters the downstream process after passing this test.

[0073] In any of the above schemes, it is preferred that the slag screen cleaning assembly includes a rubber scraper 31 installed on the inner rear side of the water storage chamber 701, and a cleaning brush 32 is installed on the upper part of the rubber scraper 31. The working ends of the cleaning brushes 32 are in contact with the lower surface of the blocking filter screen 10 and clean the blocking filter screen 10 by moving along the front and rear directions of the water storage chamber 701. A cleaning telescopic cylinder group 33 is fixedly installed on the ground outside the water storage chamber 701. The inner ends of the piston rods of the cleaning telescopic cylinder group 33 are movable and sealed to extend into the water storage chamber 701 and are fixedly connected to the rubber scraper 31. A number of slag-containing waste liquid discharge outlets 34 with sealing covers are installed on the side wall of the water storage chamber 701 on the side opposite to the rubber scraper 31.

[0074] The slag screen cleaning component is mainly used to clean the barrier filter screen 10 and the bottom of the water storage chamber after the upper supernatant liquid inside the wastewater source tank 7 is drained out. During cleaning, it is necessary to cooperate with the high-pressure cleaning water above the water storage chamber. The impurities on the surface of the barrier filter screen 10 can be cleaned by the cleaning water. At the same time, the cleaning telescopic cylinder group 33 is started to drive the rubber scraper 31 inside the water storage chamber to move back and forth, thereby cleaning the impurities on the bottom and side walls of the water storage chamber. At this time, during the movement of the rubber scraper 31, the cleaning brush 32 with a certain hardness on it can quickly brush the barrier filter screen 10. The impurities brushed off will fall directly into the water storage chamber below under the action of the impact water flow above. The waste liquid can be discharged by opening the various slag waste liquid discharge outlets at the lower part of one side of the water storage chamber. The water storage chamber and the barrier filter screen 10 can be cleaned by repeating several times.

[0075] The side wall of the water storage chamber above the blocking filter net 10 can be directly cleaned by the impact of water flow, and the cleaned water will fall to the bottom of the blocking filter net 10 and be discharged.

[0076] In any of the above schemes, it is preferred that the comprehensive regulation unit b includes a comprehensive regulating tank 35 connected to the post-filtration pipeline 22 upstream thereof, and the required bacteria, drugs and reagents are placed in the comprehensive regulating tank 35 to neutralize and biodecompose the internal wastewater. The output end of the comprehensive regulating tank 35 is connected to the inlet end of the sedimentation tank 2, and a water quality sampler 20 is installed on the pipeline at the output end of the comprehensive regulating tank 35. A regulating tank cover 36 is installed on the top of the comprehensive regulating tank 35, and a comprehensive multi-stage mixing component is installed on the regulating tank cover 36. The comprehensive multi-stage mixing component is used to realize multi-effect mixing treatment of the wastewater into which bacteria, drugs and reagents are placed.

[0077] The comprehensive regulation unit b mainly neutralizes and biodegrades the internal wastewater by adding the required bacteria, drugs and reagents into it. The treated water can greatly reduce the content of harmful substances and impurities in the internal water, and the organic matter in the internal water is decomposed by the bacteria to make the solution clearer. When the required bacteria, drugs and reagents are added to neutralize and biodegrade the internal wastewater, the comprehensive multi-stage mixing component can be started to improve the mixing effect, promote the internal reaction speed and effect, and finally achieve the purpose of multi-effect mixing. The water quality sampler 20 at this position can be used to take samples and then test to obtain the current water quality effect. During the waste liquid treatment process, sampling and testing can be performed intermittently multiple times to better monitor the treatment of the internal waste liquid.

[0078] In any of the above schemes, it is preferred that the integrated multi-stage mixing assembly includes a long gear box 37 fixedly mounted on the top of the regulating tank cover 36, a horizontal main shaft 38 is installed in the long gear box 37, and a fixed bearing seat 39 is respectively matched on both sides of the horizontal main shaft 38, and a two-way side mixer 40 is respectively installed at both ends of the horizontal main shaft 38, and a middle mixer 41 is provided between the two two-way side mixers 40. The two two-way side mixers 40 and the middle mixer 41 cooperate to achieve mixing and stirring of the wastewater inside the integrated regulating tank 35; a main shaft driving member is installed in the long gear box 37 between the middle mixer 41 and the two-way side mixer 40 on the left, and the main shaft driving member is used to drive the horizontal main shaft 38 to operate and drive the two two-way side mixers 40 and the middle mixer 41 to operate synchronously;

[0079] The middle mixer 41 includes a middle driving bevel gear 42 fixedly mounted on the middle outer wall of the horizontal main shaft 38, and a middle driven bevel gear 43 is meshed below the middle driving bevel gear 42. The central mixing shaft 44 of the middle driven bevel gear 43 is movably extended below the regulating chamber 45 of the integrated regulating tank 35 and a plurality of central stirring teeth 46 are fixedly mounted on its outer wall. A supporting copper ring 47 is sleeved on the outer wall of the central mixing shaft 44 between the middle driven bevel gear 43 and the inner cavity of the long gear box 37, and the bottom of the supporting copper ring 47 is fixed on the inner cavity of the long gear box 37.

[0080] The integrated multi-stage mixing assembly mainly utilizes the main shaft drive as a single power component when working. When the main shaft drive is in operation, it drives the two-way side mixers 40 at both ends and the middle mixer 41 in the middle to work simultaneously. Since the two-way side mixers 40 and the middle mixer 41 work synchronously, they can better ensure the full mixing of the internal water and bacteria, drugs and reagents, ensure the contact between bacteria, drugs and reagents and waste liquid, and improve the treatment effect.

[0081] When the main shaft driving member drives the corresponding horizontal main shaft 38 to operate, the rotation of the horizontal main shaft 38 can drive the rotation of the middle driving bevel gear 42 thereon, and the middle driven bevel gear 43 engaged with it can be driven to rotate on a fixed axis through the middle driving bevel gear 42, thereby driving the central mixing shaft 44 connected thereto to rotate on a fixed axis. During the rotation of the central mixing shaft 44, the central stirring teeth 46 located inside the regulating chamber 45 can be driven to quickly stir the water. During the rotation, the supporting copper ring 47 at the corresponding position can play a supporting and lubricating role.

[0082] In any of the above schemes, it is preferred that the main shaft drive component includes a high-torque total drive motor 48 fixedly mounted in the inner cavity of the long gear box 37, and a total drive gear 49 is fixedly mounted on the output end of the high-torque total drive motor 48, and the total drive gear 49 is meshed with the driven total gear 50 fixedly mounted on the outer wall of the horizontal main shaft 38.

[0083] The entire integrated multi-stage mixing assembly adopts a single power component of a large-torque total drive motor 48 to realize the driving operation of the two bidirectional side mixers 40 and the middle mixer 41 during operation, which can effectively realize the rapid mixing of wastewater with bacteria, drugs and reagents inside the integrated regulating tank 35, improve the mixing effect, and is suitable for use in regulating tanks of larger sizes. At the same time, the entire assembly is driven by only a single power component, which makes it easy to determine the power failure point in the later fault inspection and maintenance, and makes maintenance and repair more convenient.

[0084] In any of the above schemes, it is preferred that the bidirectional side mixer 40 includes a large end driving bevel gear 51 and a small end driving bevel gear 52 fixedly mounted on the outer side wall of the end of the horizontal main shaft 38, and the small end driving bevel gear 52 is located on the outside of the large end driving bevel gear 51, and a coaxially arranged large end driven bevel gear 53 and a small end driven bevel gear 54 are meshed below the large end driving bevel gear 51 and the small end driving bevel gear 52. An outer vertical tube 55 and an inner vertical tube 56 are respectively fixed below the large end driven bevel gear 53 and the small end driven bevel gear 54, and the inner vertical tube 56 is inserted into the cavity of the outer vertical tube 55. The outer riser 55 extends out from the inner and lower ends. The lower ends of the outer riser 55 and the inner riser 56 are movably extended into the regulating chamber 45 of the integrated regulating tank 35, and a number of forward agitators 57 and reverse agitators 58 are fixedly installed on their respective outer side walls. The center of each small driven bevel gear 54 at the end is through-set and connected to the central cavity of the corresponding inner riser 56. Support copper rings 47 are sleeved on the outer side wall of the inner riser 56 between the small driven bevel gear 54 at the end and the large driven bevel gear 53 at the end, and on the outer side wall of the outer riser 55 between the large driven bevel gear 53 at the end and the bottom of the inner cavity of the long gear box 37.

[0085] When the bidirectional side mixer 40 is working, it mainly relies on the transmission of the main shaft drive to drive the large end driving bevel gear 51 and the small end driving bevel gear 52 at the corresponding ends of the horizontal main shaft 38 to operate. During the operation of the large end driving bevel gear 51 and the small end driving bevel gear 52, the large end driven bevel gear 53 and the small end driven bevel gear 54 that are meshed with them will be driven to operate, thereby driving the coaxially arranged outer vertical pipe 55 and the inner vertical pipe 56 to rotate around the fixed axis. Since the lower ends of the outer vertical pipe 55 and the inner vertical pipe 56 are both located inside the regulating chamber 45 and are equipped with forward agitators 57 and reverse agitators 58, when the outer vertical pipe 55 and the inner vertical pipe 56 rotate in opposite directions, the forward agitators 57 and reverse agitators 58 at the corresponding positions will be driven to rotate coaxially and in reverse, thereby effectively improving the effect of rotational stirring, ensuring the mixing effect of the water liquid, and improving the mixing efficiency. In addition, during the rotation process, the supporting copper ring 47 at the corresponding position can play a supporting and lubricating role.

[0086] Since the forward agitator 57 and the reverse agitator 58 rotate coaxially and in opposite directions, the upper liquid and the lower liquid can be driven to rotate in opposite directions, thereby achieving convection impact, thereby ensuring the adequacy of the internal mixing effect and improving the mixing efficiency.

[0087] In addition, the four rotating shafts on the two bidirectional side mixers 40 are all driven by the same main shaft driving member, which can effectively ensure the simplification of the entire transmission structure and improve the compactness of the layout.

[0088] In any of the above schemes, preferably, a vertical and fixed feed steel pipe 59 is movably inserted into the upper central cavity of each of the inner risers 56, and the top of each of the feed steel pipes 59 passes through the top of the elongated gear box 37 and is connected to a fixed feed box 60, so that the feed box 60 is filled with bacteria, medicines and reagents and the bacteria, medicines and reagents are directly delivered to the lower part of the regulating chamber 45 through the inner risers 56;

[0089] The feeding steel pipe 59 and the feeding box 60 provided here are mainly for the purpose of directly injecting the medicine into the inner vertical pipe 56 and directly reaching the bottom of the regulating chamber 45 when adding medicine. This medicine delivery method can better ensure that the medicine flows out quickly at the bottom of the water liquid and is quickly diffused under the stirring action of the two-way side mixer 40 inside the entire regulating chamber 45, thereby improving the diffusion effect of the medicine liquid. At the same time, the entire feeding steel pipe 59 is in a fixed state when working, so it will not produce movement interference with the upper central cavity of the inner vertical pipe 56.

[0090] Alum is placed in the sedimentation tank 2 to achieve flocculation and sedimentation of the internal water liquid. A water quality sampler 20 is installed on the upper part of the outlet of the sedimentation tank 2. The outlet end of the sedimentation tank 2 transports the regulated water liquid to the downstream through the post-settlement delivery pipeline 61. The multi-stage water quality membrane filtration purification unit 3 is installed on the post-settlement delivery pipeline 61.

[0091] A water quality sampler 20 is installed at the upper part of the outlet of the sedimentation tank 2, which can detect the quality of the water inside the current sedimentation tank 2 by rapid sampling and testing. At the same time, alum or the like can be added into the sedimentation tank 2 to increase the speed and effect of the internal suspended matter settling.

[0092] Example 2:

[0093] The difference between this embodiment and embodiment 1 is that:

[0094] The multi-stage water quality membrane filtration purification unit 3 includes a first filter 62, a second filter 63, a third fine filter 64, and a fourth fine filter 65 installed in series on the post-settling delivery pipe 61. The end of the fourth fine filter 65 is connected to the domestic water deep treatment end 5 through a domestic water diversion pipe 66. A water quality sampler 20, a control valve, and a power pump are installed on the domestic water diversion pipe 66.

[0095] The industrial water pipeline 67 between the second filter 63 and the third fine filter 64 is connected to the industrial water end 4 , and a water quality sampler 20 , a control valve, and a power pump are installed on the industrial water pipeline 67 .

[0096] The multi-stage filtration structure adopted by the entire multi-stage water quality membrane filtration purification unit 3 is composed of a series of components. The quality requirement of the water flowing to the industrial water end 4 is lower than the quality requirement of the water flowing to the domestic water deep treatment end 5. Therefore, the industrial water end 4 only needs to be filtered through the first filter 62 and the second filter 63, while the domestic water deep treatment end 5 needs to be filtered four times through the first filter 62, the second filter 63, the third fine filter 64, and the fourth fine filter 65 to achieve a better filtration effect. In addition, during the water transportation process, the water quality sampler 20 is used to detect and ensure that the water quality meets the standard before it is transported downstream.

[0097] In any of the above schemes, it is preferred that a bend pipe material accumulation section 68 is provided in the middle of the connecting pipe between the first filter 62 and the second filter 63, and magnetized magnetic blocks 69 are respectively installed on the upper and lower parts of the connecting pipe on both sides of the bend pipe material accumulation section 68. The relatively arranged magnetized magnetic blocks 69 constitute a magnetizing magnetic field, and the magnetizing magnetic field is used to magnetize the water flowing through the connecting pipe. The bend pipe material accumulation section 68 is used to accumulate impurities generated during the transportation process, and an impurity discharge valve 70 is installed at the bottom of the bend pipe material accumulation section 68.

[0098] The internal iron impurities can be processed by the magnetizing effect of the magnetizing magnetic field on the internal water. At the same time, when the water flow after sequential magnetization passes through the bend pipe accumulation section 68, the water flow is reduced, and the internal impurities will accumulate here, so that the impurities in the downward flowing water are reduced again, ensuring the cleanliness of the water quality after magnetization. At the same time, opening the impurity discharge valve 70 at the bend pipe accumulation section 68 can discharge the impurities accumulated there, thereby achieving the purpose of quickly cleaning the impurities; after the impurities are accumulated at the bend pipe accumulation section 68, the water flow that continues to flow backward can continue to be magnetized by the next group of magnetizing magnetic fields, thereby improving the water quality again.

[0099] Specific working principle:

[0100] The system for achieving comprehensive water quality treatment at a water plant based on influent dynamics utilizes a water flow sensor 6 to monitor incoming wastewater flow in real time, providing feedback to the water plant control center to manually control each unit of the system, adjusting on demand for greater energy savings. Wastewater entering the system first passes through the inlet of the oil-separator filter unit a and enters the oil-separator filter unit a. The water flow in this configuration enters from the bottom of the oil-separator filter unit a and then rises from the middle to raise the liquid level.

[0101] The wastewater is sent to the downstream integrated regulation unit b after degreasing and filtering the wastewater in the wastewater source pool 7 of the oil-separating and filtering residue unit a. Bacteria, drugs and reagents are added to the integrated regulation unit b, and sufficient and rapid mixing is achieved in the integrated multi-stage mixing component to ensure the uniformity of the mixing.

[0102] After the conditioning treatment, the pollutants in the water liquid are greatly reduced, and then, after further treatment in the multi-stage water quality membrane filtration purification unit 3, it reaches the standards for domestic and industrial use.

[0103] Similarly, the mud-containing wastewater and slag-containing wastewater generated at the end of each unit will be transported to the external sludge treatment process for sludge purification and drying to ensure that the water quality in each link meets the standards.

[0104] In this system, a water quality sampler 20 is installed in each unit. After the water sampler 20 takes out the water sample, it is sent to the outside for testing. After passing the test, it enters the next process, ensuring the water quality treatment effect.

[0105] The system for realizing comprehensive water quality treatment of water plants based on the dynamics of water inflow in the present invention is applied to wastewater treatment in water plants, and can monitor the water inflow of the entire system in real time. At the same time, the water plant control end can control the operating time and cycle of each device according to the water inflow; at the same time, a water quality sampler 20 is installed at the end of each stage, and the water samples taken out by each water quality sampler 20 are tested and fed back to the control end. The staff of the water plant control end adjusts the various devices of the system again, thereby effectively ensuring the wastewater treatment effect of the entire system; in this system for realizing comprehensive water quality treatment of water plants based on the dynamics of water inflow, the oil separation filter residue unit a can be used to realize rapid and clean separation of oil in wastewater. During separation, the floating oil outlet mechanism c can first realize preliminary oil discharge to meet the treatment of wastewater with less content, and at the same time cooperate with the wastewater oil removal equipment 30 on the fine oil removal bypass 29 to realize fine oil removal to ensure the wastewater oil removal effect.

[0106] In addition, in order to improve the oil removal effect during the initial oil removal, the present invention also provides an air flotation and drainage combination mechanism, through the operation of the air flotation and drainage combination mechanism, the wastewater inside the wastewater source tank 7 can be continuously filled with pulse airflow (oxygen or air), so that the air bubbles can quickly drive the floating oil to float upward, thereby improving the oil-liquid separation effect; the operation of the floating oil outlet mechanism c can realize the rapid outlet of the upper floating oil mixture; during the operation of the air flotation and drainage combination mechanism, the lifting and lowering of the lifting and positioning cylinder group 23 can be controlled to achieve the stirring and mixing of the waste liquid while carrying out the pulse airflow impact; the waste liquid after the oil residue is removed is comprehensively treated in the comprehensive regulating tank 35, and at the same time, the comprehensive multi-stage mixing component can be used to better mix the waste liquid and the reagent inside the regulating chamber 45 during the treatment process, thereby improving the treatment effect and ensuring the treatment efficiency, and can be effectively applied to the large-scale comprehensive regulating tank 35.
