Description

Technical Field

[0001] This invention relates to the field of river sewage treatment equipment, and in particular to a high-efficiency river sewage treatment device. Background Technology

[0002] Current mainstream river wastewater treatment devices still have many technical shortcomings in practical applications, making it difficult to meet the needs for efficient, economical, and thorough treatment.

[0003] Existing devices mostly rely on a single stirring structure to mix chemicals and wastewater. This limited stirring method and fixed eddy current direction result in insufficient contact and uneven mixing between chemicals and wastewater. Some areas exhibit excessively high chemical concentrations while others remain uncontaminated, preventing suspended impurities in the wastewater from quickly forming stable flocs. Furthermore, to improve floc settling efficiency, some devices add magnetic particles to assist flocculation, imbuing the flocs with magnetism to accelerate separation. However, existing devices lack a magnetic particle recycling mechanism; the magnetic particles are discharged with the sludge and discarded, increasing the cost of consumable materials and complicating subsequent sludge treatment due to their contamination. This contradicts the "cost reduction and efficiency improvement" governance philosophy and the sustainability requirements of ecological governance. Moreover, most devices only achieve preliminary wastewater purification through flocculation and sedimentation, failing to design deep purification structures for residual fine impurities, dissolved organic matter, and odorous substances in the flocculated water. This results in effluent quality failing to meet river discharge standards, and the purified water, when re-discharged into rivers, may still cause secondary impacts on the aquatic ecosystem, failing to fundamentally improve river water quality.

Simultaneously, adjacent turbine blades create opposing vortices, ensuring thorough mixing of wastewater and reagents, accelerating impurity flocculation, and improving reaction efficiency. This enables the initial separation of impurities from wastewater. Furthermore, the combination of the discharge mechanism and the magnetic separator facilitates the recycling of magnetic materials back into the first cavity after magnetic separation, enabling the reuse of magnetic particles and saving processing costs. Finally, the combination of the filter plate and the activated carbon adsorption layer facilitates deep water purification, improving effluent quality and achieving compliant discharge. Ultimately, this solves the problems of low sludge flocculation reaction efficiency, insufficient resource utilization, and inadequate wastewater treatment in river wastewater management.

[0025] The analysis module clarifies the positive correlation between magnetic field effect and magnetic susceptibility, sets the magnetic susceptibility fluctuation range, and further derives the threshold range of magnetic field duration. This prevents the magnetic susceptibility from exceeding the upper limit due to excessive magnetic field duration, which would lead to over-magnetization of the material and difficulty in demagnetization, affecting subsequent flocculation effects. By analyzing the relationship between magnetic field duration and magnetic susceptibility, the duration can be dynamically adjusted based on real-time collected magnetic susceptibility data, which is more energy-efficient than the "constant magnetic field strength + fixed running time" mode used in traditional devices. By periodically calculating the actual particle size and volume of magnetic particles, the lifespan of magnetic particles can be accurately controlled, avoiding "overuse" or "premature replacement".

[0037] In this invention, the sewage discharge mechanism includes a first slurry pump 13 installed directly below the slurry storage silo 12, which facilitates the pumping of flocculated sludge from the slurry storage silo 12 into a first slurry conveying pipe 14; the input end of the first slurry pump 13 is connected to the sewage discharge port at the bottom of the slurry storage silo 12, and the output end of the first slurry pump 13 is connected to the first slurry conveying pipe 14, which facilitates the conveying of some flocculated sludge into the first cavity; a second slurry conveying pipe 15 is connected to the first slurry conveying pipe 14, which facilitates the conveying of some flocculated sludge to a second slurry pump 16; and a second slurry pump 16 is installed on one side of the first slurry pump 13, which facilitates the conveying of some flocculated sludge into the first cavity; The second slurry pump 16 facilitates the transport of some flocculated sludge to the magnetic separator 24 in conjunction with the third sludge conveying pipe 17. The other end of the second sludge conveying pipe 15 is connected to the input end of the second slurry pump 16, and the output end of the second slurry pump 16 is connected to the third sludge conveying pipe 17. The magnetic separator 24 is mounted on the top surface of the mounting base 2, facilitating the separation of flocculated sludge from magnetic particles. The other end of the third sludge conveying pipe 17 is connected to the magnetic separator 24, and a sludge conveying branch 27 is provided on the third sludge conveying pipe 17. This branch facilitates the direct transport of less flocculated magnetic particles to the first cavity. The other end of the sludge conveying branch 27 is located inside the first cavity. Furthermore, a fourth sludge conveying pipe 26 is installed at the rear end of the magnetic separator 24, which facilitates the discharge of the separated sludge; a magnetic material outlet 25 is installed at the front end of the magnetic separator 24, which facilitates the reintroduction of the separated magnetic particles into the first cavity for recycling; the magnetic material outlet 25 is located directly above the first cavity, and three reagent tanks 18 containing different reagents are provided at the rear end of the main body 1, which facilitates the placement of different reagents; each of the three reagent tanks 18 is connected to a drug delivery pipe 19, and the other ends of the three drug delivery pipes 19 are respectively located inside multiple first cavities. The purification mechanism includes the components installed in the main body 1... The filter plate 20 on the inner wall of the body 1 prevents flocculation from entering the activated carbon adsorption layer 21. The filter plate 20 is located in the second cavity, and the activated carbon adsorption layer 21 is placed on the upper end of the filter plate 20, which facilitates the purification of sewage. The upper end of the activated carbon adsorption layer 21 is provided with a drainage trough 22, which facilitates the discharge of purified water from the body 1. Multiple interconnected water purification tanks 23 are connected to both sides of the drainage trough 22, which facilitates the collection and transportation of filtered water to the drainage trough 22. Multiple water inlets are equidistantly opened on the water purification tanks 23, and the other end of each water purification tank 23 is installed on the inner wall of the body 1.

[0038] Working Principle: When using this invention, first connect the power supply to the device and turn on all electrical appliances. Pump sewage into the main body 1 through the sewage inlet using the sewage suction pipe. Then, turn on the first motor 4. The first motor 4 is connected via a coupling and drives the first rotating shaft 5 to rotate, which in turn drives the turbine blades 6 to rotate. Due to the inconsistent vortex directions formed by the turbine blades 6, combined with the internal structure of the main body 1, a water flow trajectory moving towards the second cavity can be formed. At this time, the three chemical tanks 18 respectively add coagulant, magnetic particles, and flocculant into the first cavity. Through the stirring of the turbine blades 6, the flocculant mixes and flocculates with the sewage. The addition of magnetic particles gives the flocculant a partial magnetic property, increasing its attraction to impurities. Simultaneously, the magnetic particles also increase the mass of the flocculant itself, making it easier to settle. After reaching the second cavity, the flocculant containing the magnetic particles settles onto the guide platform 11 under its own gravity. When the second motor 7 drives the second rotating shaft 8 to rotate the stirring frame 9, the precipitated flocculation is guided towards the trough opening by the guide plate 10 and then falls into the sludge storage bin 12. At this time, the first slurry pump 13 and the second slurry pump 16 start, pumping the flocculation in the sludge storage bin 12 to the first sludge conveying pipe 14. The first sludge conveying pipe 14 pumps the flocculation into the first cavity, and then, in conjunction with the second sludge conveying pipe 15, pumps some of the flocculation through the second slurry pump 16 to the magnetic separator 24. A sludge conveying branch 27 is separated from the second sludge conveying pipe 15, which is equipped with a filter screen. Flocculation containing more magnetic particles is too large to pass through the filter screen and be conveyed to the magnetic separator 24. Flocculation with smaller mass directly enters the first cavity for re-flocculation. The magnetic separator 24 separates the flocculation from the magnetic particles. The magnetic particles are discharged back into the first cavity through the magnetic material outlet 25 for recycling, while the flocculated sludge is discharged through the fourth sludge conveying pipe 26.

[0039] Example 2: See Figure 7 The control box of the wastewater treatment device is equipped with intelligent control components, which include a data acquisition module, an analysis module, and an execution module.

This refers to the duration of the magnetic field's action; taking magnetic flocculation-magnetic separation technology in wastewater treatment as an example, the magnetic susceptibility is typically within... Within this range, the magnetic susceptibility fluctuation range is set accordingly. The magnetic susceptibility affected by the overall factors is: ,even though Stay Within the range, duration of magnetic field action Must meet: and ,Right now and During the separation of magnetic particles by the magnetic separator 24, the duration of the magnetic field is controlled.
