Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a system for removing suspended matter from wastewater. Background Art

[0002] In the existing wastewater treatment technology, traditional filter media systems have many problems when treating wastewater. In the process of treating wastewater with traditional filter media systems, the use of filter media easily leads to the accumulation of sludge and biofilm in the filter layer, which not only reduces the water quality standard, but also may promote the growth of bacteria, thereby causing water pollution. Traditional filter media systems need to be backwashed regularly to remove impurities on the filter media. This operation process is not only time-consuming and labor-intensive, but also causes a large waste of water resources due to the use of flushing water. Since traditional filter media are easily contaminated, contamination or damage of the filter media will lead to a significant decrease in filtration efficiency. Over time, impurities in the filter media gradually accumulate, and the filtration rate slows down, requiring more frequent backwashing, which not only increases maintenance costs, but may also affect the continuous treatment of wastewater.

[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] like Figure 1 and Figure 2 As shown, the suspended solids removal system 100 of the wastewater of the embodiment of the present invention comprises a cyclone separator 1, a drain pipe 2, a sewage pipe 3, a water inlet pipe 4, a first water pump 5 and a first feeding pipe 6. The drain pipe 2 and the sewage pipe 3 are respectively arranged at the top and the bottom of the cyclone separator 1, the drain pipe 2 is used to discharge the separated wastewater, and the sewage pipe 3 is used to discharge the separated sludge. The water inlet pipe 4 is arranged on the side wall of the cyclone separator 1 and one end thereof extends into the cyclone separator 1. The inlet end of the water inlet pipe 4 is connected to the first water pump 5 to transport wastewater to the water inlet pipe 4. The outlet end of the water inlet pipe 4 is arranged along the tangent direction of the cyclone separator 1 so that the wastewater forms a cyclone after entering the cyclone separator 1. The first feeding pipe 6 is connected to the water inlet pipe 4 and is used to transport a coagulant or a flocculant into the water inlet pipe 4.

[0022] When the system 100 for removing suspended matter from wastewater according to the embodiment of the present invention is in use, the wastewater is transported to the cyclone separator 1 by the first water pump 5 through the water inlet pipe 4. The outlet end of the water inlet pipe 4 is arranged along the tangent direction of the cyclone separator 1, so that the wastewater forms a cyclone after entering the cyclone separator 1. In the cyclone separator 1, the suspended matter in the wastewater is thrown toward the wall of the device under the action of the cyclone and the centrifugal force. Since the density of the suspended matter is greater than that of water, they will migrate toward the wall of the device under the action of the cyclone and settle under the action of gravity. The first feeding pipe 6 transports coagulant or flocculant into the water inlet pipe 4, which can cause the fine suspended particles in the wastewater to aggregate into larger flocs, which is convenient for separation in the cyclone separator 1. The separated sludge is discharged through the sewage pipe 3, and the wastewater treated by the cyclone separator 1 is discharged through the drain pipe 2, thereby achieving the removal of suspended matter.

[0023] The wastewater suspended matter removal system 100 provided by the present invention enables the suspended matter to be separated efficiently, reduces the accumulation of sludge and biofilm during the treatment process, and thus improves the water quality. The system does not need to backwash the filter material regularly, so it can save a lot of water resources, while reducing water consumption and energy consumption. Since there is no need to replace the filter material, the maintenance cost of the system is relatively low. The design of the cyclone separator 1 also makes the maintenance and operation of the system easier. The system can reduce the decrease in filtration efficiency due to contamination or damage of the filter material and maintain the stability of the filtration process. The cyclone separator 1 can adapt to the continuous wastewater treatment process, reducing the interruption and downtime in the wastewater treatment process. Therefore, the wastewater suspended matter removal system 100 provided by the present invention achieves efficient removal of wastewater suspended matter through cyclone separation technology, and has the beneficial effects of saving water, reducing maintenance costs, enhancing filtration stability and being suitable for continuous treatment.

[0024] In some embodiments, there are multiple water inlet pipes 4 , and the multiple water inlet pipes 4 are arranged at intervals along the circumference of the cyclone separator 1 .

[0025] Wastewater enters the cyclone separator 1 through multiple water inlet pipes 4. The arrangement of these water inlet pipes 4 can disperse the wastewater before entering the cyclone separator 1, which helps to form a more uniform cyclone. Multiple water inlet pipes 4 are arranged at intervals along the circumference to produce multiple cyclone points. These cyclone points cooperate with each other to enhance the cyclone effect inside the cyclone separator 1. Due to the uniformity of the incoming water and the enhancement of the cyclone effect, the suspended matter in the wastewater is more likely to migrate to the wall of the device under the action of centrifugal force and settle under the action of gravity, thereby improving the separation efficiency of the suspended matter. When a single large-diameter water inlet pipe 4 is used, there is a risk of clogging the water inlet pipe 4 due to the aggregation of suspended matter. The design of multiple small-diameter water inlet pipes 4 can reduce this risk and maintain the stability of the system operation.

[0026] In some embodiments, Figure 2As shown, the water inlet pipe 4 includes a first pipe section 401 and a second pipe section 402 connected to each other, and the first pipe section 401 is arranged perpendicular to the second pipe section 402. One end of the second pipe section 402 extends into the cyclone separator 1, the first pipe section 401 is arranged outside the cyclone separator 1 and connected to the first water pump 5, and the first feeding pipe 6 is connected to the first pipe section 401.

[0027] The first feeding pipe 6 is connected to the first pipe section 401, and is used to transport coagulants or flocculants into the water inlet pipe 4, which is conducive to the pre-coagulation or flocculation treatment of suspended matter in the wastewater before the wastewater enters the cyclone separator 1. The wastewater is pumped to the first pipe section 401 by the first water pump 5, and then flows into the second pipe section 402. When the wastewater flows from the first pipe section 401 to the second pipe section 402, the flow direction of the wastewater changes because the first pipe section 401 is perpendicular to the second pipe section 402, which helps to form a stronger cyclone when entering the cyclone separator 1. Through the segmented design of the water inlet pipe 4, the removal efficiency of suspended matter in the wastewater is improved, and it is also conducive to saving chemicals and reducing operating costs. In addition, this design also makes the maintenance and operation of the system easier, and improves the stability and reliability of the system.

[0028] In some embodiments, a second feeding pipe 7 is further provided on the side wall of the cyclone separator 1 , and the second feeding pipe 7 is used to add a coagulant or a flocculant into the cyclone separator 1 .

[0029] Different from the first feeding pipe 6, the second feeding pipe 7 directly adds the coagulant or flocculant into the cyclone separator 1, so that the position and effect of the chemical reaction can be more accurately controlled. Since the coagulant or flocculant directly acts on the wastewater in the cyclone separator 1, it helps to quickly form flocs and improve the separation efficiency of suspended matter.

[0030] In some embodiments, the wastewater suspended matter removal system 100 of the embodiment of the present invention also includes a stirring shaft 8, a stirring impeller 9 and a motor 10. The stirring shaft 8 is rotatably disposed on the bottom wall of the cyclone separator 1 and one end extends into the cyclone separator 1. The motor 10 is disposed outside the cyclone separator 1 and connected to the stirring shaft 8. The stirring impeller 9 is disposed inside the cyclone separator 1 and connected to the stirring shaft 8.

[0031] When the motor 10 is started, the stirring shaft 8 and the stirring impeller 9 start to rotate. The rotation of the stirring impeller 9 produces a stirring effect in the cyclone separator 1, which helps the coagulant or flocculant to be evenly distributed in the wastewater and fully mixed with the suspended matter. The stirring action can accelerate the chemical reaction between the coagulant or flocculant and the suspended matter, promote the formation of flocs, and thus improve the separation efficiency of the suspended matter. The rotation of the stirring shaft 8 can also help the wastewater form a vertical flow in the cyclone separator 1, further strengthen the cyclone effect, and help separate the suspended matter.

[0032] In some embodiments, the wastewater suspended matter removal system 100 of the embodiment of the present invention further includes a sewage pump 11, which is connected to the sewage pipe 3 and is used to discharge the separated sludge.

[0033] The wastewater suspended matter removal system 100 of the embodiment of the present invention can effectively discharge the separated sludge through the sewage pump 11 and the sewage pipe 3, so as to keep the cyclone separator 1 clean and operate efficiently. Regularly discharging sludge can reduce the accumulation of sludge in the system and reduce the risk of clogging the cyclone separator 1 or other processing components. Effectively discharging sludge contributes to the long-term stable operation of the system, improves the reliability of the system and the continuity of wastewater treatment. The design of the sewage pump 11 enables the sludge to be effectively discharged from the system, thereby reducing the storage space required for sludge accumulation. Discharging sludge through a special sewage pipe 3 can ensure that the discharge of sludge meets environmental protection requirements and reduces the impact on the environment.

[0034] In some embodiments, a sewage valve 12 is provided at the outlet of the sewage pump 11 .

[0035] The blowdown valve 12 can control the discharge flow of the sludge. The design of the blowdown valve 12 can adjust the discharge speed of the sludge to adapt to different treatment needs and environmental requirements. In some cases, the blowdown valve 12 can also play a role of safety protection to prevent the system from excessively discharging sludge in unexpected circumstances and avoid affecting the environment.

[0036] In some embodiments, the wastewater suspended matter removal system 100 of the embodiment of the present invention also includes a second water pump 13 and a sedimentation tank 14. The drain pipe 2 is connected to the second water pump 13. The second water pump 13 is used to transport the separated wastewater into the sedimentation tank 14. The sedimentation tank 14 is used to precipitate the separated wastewater.

[0037] The wastewater treated by the cyclone separator 1 flows to the second water pump 13 through the drain pipe 2. After the second water pump 13 is started, the wastewater is transported to the sedimentation tank 14. In the sedimentation tank 14, the remaining suspended matter and fine particles in the wastewater settle to the bottom under the action of gravity to form a sludge layer. With the sedimentation of the suspended matter, the concentration of the suspended matter in the wastewater gradually decreases, and the water quality is further purified. The sludge at the bottom of the sedimentation tank 14 can be discharged regularly through the sludge discharge pipe, or processed by other methods, such as further concentration, dehydration, etc.

[0038] The design of the sedimentation tank 14 helps to further remove suspended matter in the wastewater and improve the water quality standard of the final discharged water. Through the treatment of the sedimentation tank 14, the content of suspended matter in the wastewater can be significantly reduced, which is beneficial to protecting the environment and water resources. The sedimentation tank 14 helps to reduce the pollution to the cyclone separator 1 and other processing equipment and reduce the maintenance cost of the system. The setting of the sedimentation tank 14 makes the system more stable, can cope with the changes in different water qualities, and improve the processing capacity of the system.

[0039] In some embodiments, a discharge pipe 15 is provided at the bottom of the sedimentation bin 14 , and the discharge pipe 15 is used to discharge the sedimentation medium in the sedimentation bin 14 . A discharge valve 16 is provided on the sewage pipe 3 .

[0040] In the sedimentation tank 14, the suspended solids and fine particles in the wastewater settle under the action of gravity to form a sludge layer. When the sludge needs to be discharged, the sludge can be discharged by opening the discharge pipe 15 at the bottom of the sedimentation tank 14. The drain valve 12 is provided on the drain pipe 3 to control the discharge flow and timing of the sludge. The operator can adjust the opening of the drain valve 12 according to the operation of the system and the accumulation of sludge. In some embodiments, the drain valve 12 and the drain pipe 15 may be equipped with an automated control system to automatically adjust the discharge process according to the accumulation of sludge and the processing requirements.

[0041] In some embodiments, the wastewater suspended matter removal system 100 of the embodiment of the present invention also includes an overflow pipe 17 and a clear water tank 18. The overflow pipe 17 is arranged at the top of the sedimentation bin 14 and is arranged horizontally. The overflow pipe 17 is used to overflow the wastewater after sedimentation in the sedimentation bin 14 into the clear water tank 18.

[0042] In the sedimentation tank 14, suspended solids and fine particles in the wastewater settle under the action of gravity, while relatively clean water remains in the upper part of the sedimentation tank 14. When the liquid level in the sedimentation tank 14 rises and reaches the height of the overflow pipe 17, the relatively clean water will flow into the clean water tank 18 through the overflow pipe 17. This process does not require additional pumping equipment and is completed naturally by gravity. The water quality flowing into the clean water tank 18 is relatively good and can be further processed or directly discharged into the environment. The sludge at the bottom of the sedimentation tank 14 can be discharged regularly through the sewage pipe 3 and the discharge valve 16.

[0043] The wastewater suspended solids removal system 100 of the embodiment of the present invention can further improve the water quality of the treated wastewater through the design of the overflow pipe 17 and the clean water tank 18, so that the water in the clean water tank 18 reaches a higher purification standard. The overflow process is completed naturally by gravity without the need for additional energy input, which helps to reduce the operating cost of the system. The design of the overflow pipe 17 and the clean water tank 18 simplifies the operating process and reduces the complexity of maintenance and monitoring. The overflow pipe 17 and the clean water tank 18 help to maintain the stability of the liquid level in the sedimentation tank 14, and improve the processing efficiency and stability of the entire system.
