[0002] Recycled water refers to wastewater or rainwater that has been properly treated to meet certain water quality indicators and certain usage requirements and can be used for beneficial purposes. Compared with seawater desalination and inter-basin water transfer, recycled water has obvious advantages. From an economic perspective, recycled water has the lowest cost. From an environmental perspective, wastewater recycling helps improve the ecological environment and achieve a virtuous cycle of water ecology.

[0003] The pollutant content in suspended matter in water bodies is usually higher than that in the water itself. Therefore, in the process of regenerating rivers and lakes with recycled water, in addition to considering whether the water quality meets the standards, the suspended matter pollutants must also meet the standards. Suspended matter may release or adsorb some pollutants during its migration with the water body. Therefore, meeting the standards for suspended matter pollutants at the outlet of a sewage treatment plant does not necessarily mean that meeting the standards for suspended matter pollutants at the outlet of the pipeline for regenerating rivers and lakes with recycled water.

DETAILED DESCRIPTION

[0024] The embodiment of the utility model provides a device for collecting suspended matter in recycled water.

[0025] like Figures 1 to 5 As shown, the reclaimed water suspended solids collection device includes the following embodiments:

[0026] like Figure 1 to Figure 2As shown, embodiment 1 includes a drainage main pipe 1, one end of the drainage main pipe 1 is fixedly connected with a reducer 2, one end of the reducer 2 is fixedly connected with a flow meter 11, one end of the flow meter 11 is fixedly connected with a drainage pipe 3, the outer side of the drainage pipe 3 is fixedly connected with a fixed support 5, a collecting frame 6 is arranged on the top of the fixed support 5, a lifting assembly is arranged on the fixed support 5 and the collecting frame 6, a hose 601 is fixedly connected between the collecting frame 6 and the drainage pipe 3, one end of the drainage pipe 3 away from the collecting frame 6 is fixedly connected with a solenoid valve 4, a switching frame 7 is rotatably connected inside the collecting frame 6, two filter bags 8 for filtering suspended matter are arranged inside the switching frame 7, and a locking assembly for limiting the switching frame 7 is arranged on the outer side of the collecting frame 6.

[0027] The lifting assembly includes an electric telescopic rod 501 , which is fixedly connected to the outside of the fixed support 5 , and the telescopic end of the electric telescopic rod 501 is fixedly connected to the collection frame 6 .

[0028] During specific implementation, in addition to considering whether the water quality of the water body meets the standard, the suspended matter pollutants must also meet the standard during the process of reclaiming rivers and lakes with recycled water. Suspended matter may release or absorb some pollutants during the migration with the water body. Therefore, the suspended matter pollutant concentration at the outlet of the sewage treatment plant that meets the standard does not necessarily mean that the suspended matter pollutant concentration at the outlet of the pipeline for reclaiming rivers and lakes with recycled water meets the standard. Therefore, in this scheme, a collection frame 6 is set, and water is passed into the collection frame 6 through a hose 601. The water containing suspended matter is discharged into the collection frame 6 with the help of the pressure during drainage. The height of the collection frame 6 is adjustable. According to the flow rate of the water monitored by the flow meter 11, the electric telescopic rod 501 is started, and the electric telescopic rod 501 pushes the collection frame 6 to move up and down to cope with different pressures. When the pressure is high, it is adjusted higher, and when the pressure is low, it is adjusted lower, so as to ensure that the flow rate is minimized while the water enters, so that it can be quickly precipitated.

[0029] like Figures 3 to 5 As shown, embodiment 2: the switching frame 7 includes a first rotating disk 701 and a second rotating disk 702, a fixing rod 703 is fixedly connected between the first rotating disk 701 and the second rotating disk 702, the fixing rod 703 passes through the collecting frame 6 and is rotatably connected to the collecting frame 6, one end of the fixing rod 703 is fixedly connected to a connecting handle 704, and the first rotating disk 701 is in contact with the inner wall of the collecting frame 6.

[0030] A connector 602 is fixedly connected to the outside of the collecting frame 6, and the connector 602 is fixedly connected to the hose 601. Two first external threaded rings 803 are fixedly connected to the inside of the first rotating disk 701. Two second external threaded rings 804 are fixedly connected to the second rotating disk 702 close to the side of the first rotating disk 701. The two first external threaded rings 803 correspond one by one to the two second external threaded rings 804 respectively.

[0031] During specific implementation, when water enters the connecting head 602 through the hose 601, the connecting head 602 and one of the filter bags 8 are at the same center of a circle, and the water is filtered through the filter bag 8 arranged between the first rotating disk 701 and the second rotating disk 702, and the suspended matter is collected in the filter bag 8. The filtered water is discharged through the drain pipe arranged on the outside of the collection frame 6. When the suspended matter in one of the filter bags 8 is collected for a period of time, the operator releases the locking component and then rotates the connecting handle 704. The connecting handle 704 drives the first rotating disk 701 and the second rotating disk 702 to rotate, and one of the filter bags 8 is rotated to the position of the connecting head 602, and the filter bag 8 collecting the suspended matter is rotated out of the collection frame 6. At this time, the switching frame 7 is locked by the locking component to avoid the situation where the collection needs to be suspended when the filter bag 8 is manually disassembled, and it is also convenient for personnel to disassemble the filter bag 8, and the operation is convenient.

[0032] like Figures 4 to 5 As shown, in this embodiment, the two ends of the filter bag 8 are respectively connected with a first internal thread ring 801 and a second internal thread ring 802 , the first internal thread ring 801 is threadedly connected to the first external thread ring 803 , and the second internal thread ring 802 is threadedly connected to the second external thread ring 804 .

[0033] In specific implementation, when the filter bag 8 collecting suspended matter is moved out of the collecting frame 6, the personnel remove the filter bag 8 from the first rotating disk 701 and the second rotating disk 702 by rotating the first external threaded ring 803 and the second internal threaded ring 802, and take out the collected suspended matter for easy cleaning and inspection.

[0034] like Figure 3 As shown, embodiment three: the locking assembly includes a positioning frame 901 arranged on one side of the second rotating disk 702, and positioning grooves 900 are opened on the outer sides of the first rotating disk 701 and the second rotating disk 702. The positioning frame 901 extends to the positioning groove 900 and is slidably connected to the first rotating disk 701 and the second rotating disk 702.

[0035] The locking assembly also includes a connecting frame 902, which is fixedly connected to one side of the positioning frame 901. A fixing plate 903 is fixedly connected to the top of the collection frame 6. The connecting frame 902 passes through the fixing plate 903 and is slidably connected to the fixing plate 903. A spring 904 is sleeved on the outer side of the connecting frame 902, and both ends of the spring 904 are fixedly connected to the positioning frame 901 and the fixing plate 903 respectively.

[0036] In specific implementation, when it is necessary to unlock the switching frame 7, the connecting frame 902 is pulled, and the connecting frame 902 drives the positioning frame 901 to move, and then the positioning frame 901 slides out of the positioning groove 900 provided by the first rotating disk 701 and the second rotating disk 702, thereby rotating the first rotating disk 701 and the second rotating disk 702. When the rotation is completed, the connecting frame 902 is released, and the spring 904 pushes the positioning frame 901 to be reinserted into the positioning groove 900 to fix the switching frame 7, which is convenient to operate.
