Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an integrated wastewater treatment system. Background Technology

[0002] With the continuous development of industrialization and infrastructure construction, the discharge of high-turbidity wastewater from fields such as mine drainage, construction mud slurry, and industrial wastewater with high suspended solids has increased significantly. This type of wastewater is characterized by high suspended solids concentration, large particle size differences, and wide turbidity fluctuations. If discharged directly without effective treatment, it will not only lead to water waste but also pose a serious threat to the ecological environment and cause environmental pollution.

[0003] Currently, traditional high-turbidity wastewater treatment processes generally adopt a segmented process of "chemical mixing—sedimentation—filtration." This technology is easy to understand and master, has matured through long-term practical application, and boasts rich experience and standards for reference. Furthermore, the equipment involved has a simple structure, low construction and maintenance costs, and can meet basic wastewater treatment needs to a certain extent, making it widely used and holding an important position in the wastewater treatment field.

[0004] While existing high-turbidity wastewater treatment technologies possess the aforementioned advantages, they suffer from the following shortcomings in practical implementation: First, the dispersed equipment results in a large footprint and high infrastructure costs (each sedimentation tank requires independent layout), and the extensive pipe connections between treatment units lead to high flow resistance, high energy consumption, and complex operation and maintenance. Second, the mixing effect of chemicals is poor, and the dosage is difficult to control precisely. Traditional pipe mixers are mostly static mixing structures with an unreasonable length-to-diameter ratio (usually less than 15:1), resulting in insufficient mixing of flocculants (such as PAC and PAM) with wastewater. This leads to small floc particles with slow settling speed, affecting treatment efficiency and increasing chemical consumption. Third, sedimentation tanks are prone to sludge floating and poor sludge discharge. The operation process is cumbersome and requires highly skilled and experienced operators, making the overall operation complex and difficult, thus impacting work efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing high-turbidity wastewater treatment technologies, such as dispersed equipment, poor reagent mixing effect, and high operational difficulty, and to provide an integrated wastewater treatment system.

[0006] This utility model is achieved through the following technical solution: an integrated sewage treatment system includes a chassis, on the top side of which are arranged a chemical tank, a purifier body, a sewage tank, a clean water tank, and a sludge tank; the chemical tank is connected by a pipe to a dosing pump for inputting chemicals, the sewage tank is connected by a pipe to a sewage pump for outputting sewage, and the outlets of the chemical tank and the sewage pump are respectively connected by pipes to a mixing mechanism capable of mixing chemicals; the outlet of the mixing mechanism is connected to the sewage inlet pipe of the purifier body, the clean water outlet of the purifier body is connected to the clean water tank through a clean water pipe, and the sewage outlet of the purifier body is connected to the sludge tank by a pipe.

[0007] All components of this system can be mounted on the chassis, forming an integrated system. In operation, the wastewater pump draws wastewater from the wastewater tank, and the dosing pump delivers chemicals from the chemical tank; the two are mixed in a pipeline mixing mechanism. The mixed wastewater enters the purifier body for treatment, and the treated clean water flows into the clean water tank for storage through a clean water pipe. The sludge separated by the purifier body is discharged into the sludge tank through the drain outlet. The clean water tank is connected to external water-using equipment via a water supply pump pipeline, and the sludge tank is connected to external sludge treatment equipment via a sewage pump pipeline. Furthermore, referencing existing pump control technology, the pumps used in this system can employ frequency conversion control to adapt to different inlet or outlet water pressures and adjust the flow rate.

[0008] A further improvement of this utility model is that the pipe mixing mechanism includes several inverted U-shaped tubes, which are arranged in parallel at equal intervals and connected in series via connecting pipes.

[0009] A further improvement of this utility model is that the ratio of the pipe length to the pipe diameter of the pipe mixing mechanism is 25:1.

[0010] A further improvement of this invention is that the inlet end of the pipeline mixing mechanism is equipped with a check valve via a flange assembly to prevent backflow of the pharmaceutical mixture.

[0011] A further improvement of this utility model is that the purifier body is equipped with a backwashing pipeline system, and the water inlet of the backwashing pipeline system is connected to the sewage pump pipeline, and the sewage outlet of the backwashing pipeline system is connected to the sludge tank pipeline.

[0012] A further improvement of this utility model is that the sewage tank, the clean water tank, and the sludge tank are connected to each other in sequence to form an integrated water tank.

[0013] A further improvement of this invention is that the sewage tank, the clean water tank, and the sludge tank are all equipped with built-in level sensors for measuring water levels.

[0014] A further improvement of this utility model is that wheels are provided on the bottom side of the chassis.

[0015] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0016] 1. This system integrates components such as the reagent tank, purifier body, wastewater tank, clean water tank, and sludge tank onto a chassis, forming a compact, integrated structure. Compared to traditional decentralized equipment, this reduces the space required for independent placement of each treatment unit, avoids extensive piping connections, lowers infrastructure costs, and facilitates transportation and installation, while improving space utilization.

[0017] 2. The system's pipeline mixing mechanism employs a unique U-shaped pipe and connecting pipe series structure, with a pipe length to diameter ratio of 25:1. This significantly increases the contact path and time between the reagent and the wastewater, allowing for more thorough mixing. Compared to traditional pipeline mixers, this design helps form larger, more easily settling flocs, improving suspended solids removal rates, reducing reagent consumption, and ultimately enhancing overall wastewater treatment efficiency while lowering treatment costs.

[0018] 3. The system's wastewater tank, clean water tank, and sludge tank are all equipped with built-in level sensors to monitor water levels in real time and provide feedback, enabling precise control of the wastewater treatment process and improving the system's automation and intelligence levels. Furthermore, wheels are installed on the underside of the chassis, giving the equipment mobility and allowing for flexible application in different wastewater treatment scenarios, meeting temporary or mobile wastewater treatment needs and enhancing the equipment's applicability.

Detailed Implementation

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] Please refer to the attached document. Figure 1 and 2 The following is a description of a specific embodiment: The integrated wastewater treatment system of this utility model includes a chassis 8. A chemical tank 1, a purifier body 6, a wastewater tank 701, a clean water tank 702, and a sludge tank 703 are arranged on the top side of the chassis 8. The chemical tank 1 is connected by a pipe to a dosing pump 4 for inputting chemicals. The wastewater tank 701 is connected by a pipe to a wastewater pump 3 for outputting wastewater. The outlets of the chemical tank 1 and the wastewater pump 3 are respectively connected by pipes to a mixing mechanism 5 capable of mixing chemicals. The outlet of the mixing mechanism 5 is connected to the wastewater inlet pipe of the purifier body 6. The clean water outlet of the purifier body 6 is connected to the clean water tank 702 via a clean water pipe 2. The sewage outlet of the purifier body 6 is connected by a pipe to the sludge tank 703.

[0026] All components of this system can be mounted on chassis 8, forming an integrated system. In use, sewage pump 3 draws sewage from sewage tank 701, and dosing pump 4 delivers chemicals from chemical tank 1; the two are mixed in pipe mixing mechanism 5. The mixed sewage enters the purifier body 6 for treatment, and the treated clean water flows into clean water tank 702 for storage through clean water pipe 2. The sludge separated by the purifier body 6 is discharged into sludge tank 703 through the drain outlet. Furthermore, the clean water tank 702 is connected to external water-using equipment via a water supply pump pipe, and the sludge tank is connected to external sludge treatment equipment via a sewage discharge pump pipe. Simultaneously, referring to existing water pump control technology, the water pumps used in this system can employ frequency conversion control to adapt to different inlet or outlet water pressures and adjust the flow rate.

[0027] This system adopts an integrated design, which reduces the number of connecting pipes between devices compared to traditional decentralized sewage treatment equipment, avoids pipe redundancy, makes the overall layout more compact, and effectively saves floor space. Moreover, the integrated design facilitates transportation and installation, reduces infrastructure costs, and improves the convenience and efficiency of sewage treatment.

[0028] For details, please refer to the appendix. Figure 3 The pipe mixing mechanism 5 includes several inverted U-shaped pipes 501, which are arranged in parallel at equal intervals and connected in series by connecting pipes 502.

[0029] The pipeline mixing mechanism 5 of this system consists of several inverted U-shaped pipes 501 arranged in series and connected in series via connecting pipes 502. As the wastewater and chemicals flow through the U-shaped pipes 501 and connecting pipes 502, their flow direction and velocity continuously change, thereby achieving more thorough mixing.

[0030] This unique U-shaped pipe 501 and connecting pipe 502 structure increases the contact path and time between wastewater and chemicals, enhancing the mixing effect. Compared to traditional simple pipe mixing methods, it allows flocculants such as PAC and PAM to mix more evenly with wastewater, which is beneficial for the subsequent formation of larger and easier-to-settle flocs, thereby improving wastewater treatment efficiency and increasing suspended solids removal rate.

[0031] For details, please refer to the appendix. Figure 1 and 2 The purifier body 6 is equipped with a backwashing pipeline system 9, and the water inlet of the backwashing pipeline system 9 is connected to the sewage pump 3 pipeline, and the sewage outlet of the backwashing pipeline system 9 is connected to the sludge tank 703 pipeline.

[0032] Referring to the backwashing technology of existing purifiers, when the purifier body 6 needs to be cleaned, the sewage pump 3 extracts the sewage and sends it into the purifier body 6 through the backwashing pipeline system 9 to backwash its interior. The sewage and impurities generated during the backwashing are discharged into the sludge tank 703 through the sewage discharge end of the backwashing pipeline system 9.

[0033] The backwashing pipeline system 9 enables regular cleaning of the purifier body 6, effectively preventing internal blockages and ensuring the purifier's treatment efficiency and lifespan. Utilizing the wastewater pump 3 to provide backwashing power simplifies the backwashing process, reduces additional equipment costs, decreases the frequency of manual maintenance, and improves the system's automation and operational reliability.

[0034] For details, please refer to the appendix. Figure 1 and 2 The sewage tank 701, the clean water tank 702 and the sludge tank 703 are connected to each other in sequence to form an integrated water tank 7.

[0035] The design of this integrated water tank 7 further enhances the integration of the system, reduces the space and connecting pipes required for separate water tanks, optimizes the equipment layout, makes the entire sewage treatment system more compact and orderly, facilitates management and maintenance, and also improves space utilization and reduces infrastructure costs.

[0036] In one embodiment, refer to the appendix Figure 3 The pipe length to pipe diameter ratio of the pipe mixing mechanism 5 is 25:1.

[0037] With the above-mentioned proportion design, the sewage and the agent have enough time and space to mix in the pipeline, and the flow state of the water in the pipeline can ensure that the agent is evenly diffused into the sewage.

[0038] This ratio optimizes the structural parameters of the pipeline mixing mechanism 5, ensuring that the reagent and sewage are fully mixed, further improving the mixing effect. Compared with traditional pipeline mixers, it can effectively reduce reagent waste, improve sewage treatment efficiency, and reduce treatment costs. At the same time, it helps to improve the sewage treatment quality of this system, resulting in lower effluent turbidity.

[0039] In one embodiment, reference is made to the appendix. Figure 3 The inlet end of the pipeline mixing mechanism 5 is equipped with a check valve 503 to prevent backflow of the pharmaceutical mixture via a flange assembly.

[0040] The check valve 503 of this system is installed at the inlet end of the pipeline mixing mechanism 5. When the sewage pump 3 and the dosing pump 4 stop working, the check valve 503 prevents the chemical mixture in the pipeline mixing mechanism 5 from flowing back into the chemical tank 1 and the sewage tank 701.

[0041] The design of this check valve 503 prevents the backflow of the chemical mixture, ensuring the normal treatment process of chemicals and wastewater, avoiding chemical waste, ensuring the stability and continuity of the wastewater treatment process, and also preventing wastewater backflow from contaminating the chemicals, ensuring the purity and effectiveness of the chemicals, extending the service life of the chemicals, and reducing operating costs.

[0042] In one embodiment, refer to the appendix Figure 2 The sewage tank 701, the clean water tank 702 and the sludge tank 703 are all equipped with a liquid level sensor 704 for measuring the water level.

[0043] Based on existing sensor technology, the liquid level sensor 704 of this system can monitor the water level in the sewage tank 701, the clean water tank 702 and the sludge tank 703 in real time, and feed the water level information back to the external control system.

[0044] By monitoring water levels in real time, precise control of the wastewater treatment process can be achieved. For example, when the water level in wastewater tank 701 reaches its upper limit, the external control system can control wastewater pump 3 to increase its pumping power or start the standby pump to ensure that wastewater enters the treatment process in a timely manner; when the water level in clear water tank 702 is too high, the relevant equipment can be controlled to adjust the treatment speed to prevent clear water from overflowing; when the water level in sludge tank 703 is close to its upper limit, it reminds staff to handle the sludge in a timely manner, ensuring the stable operation of the system, further improving the automation and intelligence level of the system, thereby effectively reducing the operational difficulty of the system and improving work efficiency.

[0045] In one embodiment, refer to the appendix Figure 1 The chassis 8 is equipped with wheels 801 on its underside. The wheels 801 enable the system to be mobile, allowing the system's position to be changed according to actual needs.

[0046] The design of the 801 wheel enhances the flexibility and applicability of the system, enabling it to meet the wastewater treatment needs of different locations. For example, in temporary construction sites or mining areas, the equipment can be moved to the location where wastewater needs to be treated at any time without the need for complex equipment installation and commissioning, greatly shortening the construction cycle of wastewater treatment facilities and reducing operating costs.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
