Abstract
Description
Technical Field
[0001] This application relates to the field of wastewater treatment technology, specifically to a fluoride-containing wastewater treatment device. Background Technology
[0002] Wastewater refers to polluted water generated during production, daily life, and other activities. It has a complex composition and contains various pollutants, such as fluoride ions.
[0003] Sensors for detecting fluoride content in wastewater typically employ ion-selective electrodes. The core of an ion-selective electrode is its sensitive membrane, which is sensitive to target ions (F...). - The response of the membrane depends on the hydration layer on the membrane surface. If it is dried for a long time, the hydration layer will be damaged, which will lead to a slower response speed, decreased sensitivity, or even failure to function properly.
[0004] Traditional wastewater treatment devices (such as the wastewater treatment device and method disclosed in CN107188344A) require the addition of chemicals in a flocculation tank for preliminary treatment of the wastewater, and then the treated wastewater is discharged into a sedimentation device for sedimentation. The detection components are located at the top of the flocculation tank. Thus, during the process of discharging wastewater from the flocculation tank into the sedimentation device and then filling the flocculation tank with new wastewater, the detection components are exposed to the air, which can easily lead to the detection components drying out and being damaged. Utility Model Content

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0029] See Figures 1 to 3 To further elaborate on this application:
[0030] A fluoride-containing wastewater treatment device includes a separation tank 10 and a detection module 20. The separation tank 10 is used to store wastewater and separate impurities in the wastewater. The detection module 20 is located inside the separation tank 10 and is used to detect the pH value and fluoride ion value of the wastewater inside the separation tank 10.
[0031] The bottom of the separation tank 10 is equipped with a sludge storage compartment 140 for storing sedimented impurities. After the wastewater is treated in the separation tank, the separated impurities will settle in the sludge storage compartment 140.
[0032] The detection module 20 includes an installation tube 210 and a detection component 220 disposed within the installation tube 210. The detection component 220 is located at the end of the installation tube 210, which extends into the wastewater to store wastewater and keep the detection component 220 moist. The detection component 220 is an ion-selective electrode; the detection end of the detection component 220 extends to the bottom of the installation tube 210.
[0033] After the separated clean water in the separation tank 10 is discharged, the installation pipe 210 can store some clean water to submerge the detection component 220, thus preventing the detection component 220 from drying out and being damaged. When new wastewater is added, the wastewater will submerge the detection component 220 again, thereby ensuring that the detection component 220 is not directly exposed to the air during the water change process, thus extending the service life of the detection component 220.
[0034] In this embodiment, the mounting pipe 210 includes a mounting section 2110 and a storage section 2120. The mounting section 2110 is used for detaching and connecting to the separation box 10. The mounting pipe 210 is hollow inside to facilitate the placement and removal of the detection component 220. The detection component 220 is disposed within the storage section 2120, which can store a portion of wastewater to keep the detection module 20 moist. The storage section 2120 has a U-shaped structure for storing wastewater; the detection component 220 is located at the bottom of the storage section 2120 to ensure that the wastewater stored in the storage section 2120 can submerge the detection component 220.
[0035] The installation section 2110 is provided with a slot 250, and the separation box 10 is provided with a locking block that matches the slot 250. The installation tube 210 can be installed or removed by engaging the slot 250 into the corresponding locking block. The slot can be U-shaped. The installation tube 210 can be a one-piece structure; alternatively, it can be a modular structure assembled from multiple parts. The separation box 10 contains several support rods 110. During installation, the liquid storage section 2120 can be fitted over the support rods 110, and the locking block correspondingly engages within the slot 250, thereby restricting the position of the detection module 20.
[0036] The liquid storage section 2120 is provided with an inlet 240 and an outlet 230 for the circulation of sewage; the inlet 240 is located at the top of the outlet 230; in this embodiment, the outlet 230 is provided on both sides of the liquid storage section 2120 to facilitate sewage circulation; ensuring that the sewage in the liquid storage section 2120 is discharged to ensure the accuracy of detection.
[0037] When the storage section 2120 is submerged in sewage, the sewage can enter through the inlet 240 and exit through the outlet 230. The sewage in the storage section 2120 can circulate to ensure that the sewage in the storage section 2120 is consistent with the sewage in the separation tank 10, thus ensuring the accuracy of the inspection. Therefore, impurities will not remain in the storage section 2120.
[0038] The inlet 240 is positioned at a height higher than the detection component 220 to ensure that the wastewater in the storage section 2120 can submerge the detection component 220.
[0039] The separation tank 10 is also provided with a drain outlet 130, which is used to discharge the separated clean water in the separation tank 10. The drain outlet 130 is higher than the sludge storage tank 140 to prevent sediment from being discharged along with the clean water. The sludge storage tank 140 is provided with a drain outlet 120 for discharging sediment that has settled in the sludge storage tank 140; the sludge storage tank 140 has a conical structure.
[0040] To facilitate the separation of wastewater within the separation tank 10, a dosing module 40 and a control module 50 are also included, along with a stirring module 30 for agitating the wastewater. The dosing module 40 adds different chemicals to the separation tank 10, and the control module 50 controls the dosage of the dosing module 40 based on the detection module 20. This allows for the addition of appropriate amounts of chemicals according to the wastewater within the separation tank 10, significantly reducing the amount of chemicals used and lowering costs. Furthermore, it occupies less space compared to existing technologies. The detection module 20 may also include sensors such as a pH meter.
[0041] As a feasible approach, the top of the separation tank 10 is provided with a support beam for mounting the stirring module 30. The stirring module 30 includes a power component and a stirring shaft arranged coaxially. Several stirring components are evenly distributed on the stirring shaft. The power component drives the stirring shaft to rotate, thereby ensuring thorough mixing of the wastewater and the reagent. The power component can be a motor; the stirring components can be stirring rods or stirring blades, with no limitation here. By driving the stirring shaft with the power component, the stirring components rotate, stirring the wastewater and ensuring thorough mixing of the added reagent with the wastewater.
[0042] The dosing module 40 includes several dosing tanks for storing different chemicals, and corresponding delivery pumps for delivering the chemicals into the separation tank 10. Each dosing tank contains one chemical. The control module 50, based on the detection module 20, controls the corresponding delivery pump to pump the chemicals sequentially into the separation tank 10 via pipelines in a set order.
[0043] The control module 50 is electrically connected to the detection module 20, the dosing module 40, and the stirring module 30; it is used to control the operation of the detection module 20, the dosing module 40, and the stirring module 30. The control module 50 can be a controller. By real-time detection of various indicators of wastewater by the detection module 20, the control module 40 adds appropriate agents (such as sodium hydroxide, flocculant, and defluoridator) to the wastewater, and then the stirring module 30 stirs and mixes the wastewater, which is then discharged after sedimentation.
