Description

Technical Field

[0001] This utility model relates to the field of wastewater heavy metal filtration equipment, and in particular to an intelligent monitoring type wastewater heavy metal filtration device. Background Technology

[0002] Intelligent monitoring-type wastewater heavy metal filtration devices, as advanced water treatment equipment, have been widely used in wastewater treatment in industries such as electroplating, smelting, and electronics. This device integrates physical filtration, chemical reaction, and intelligent monitoring and control technologies to achieve efficient separation and removal of heavy metal ions from wastewater. In the treatment process, wastewater first passes through a physical filtration unit, where large particles and suspended solids are intercepted by the filter screen for preliminary purification. Subsequently, the wastewater enters a chemical reaction unit, such as an acidolysis tank, where specific acids are added to promote the reaction of heavy metal ions, forming salts or precipitates. In the aeration tank, air is introduced to promote the oxidation of organic matter, thereby reducing its concentration.

[0003] In terms of intelligent monitoring, the device is equipped with advanced sensors and a control system. The sensors can monitor water quality parameters in real time, while the control system automatically adjusts the treatment process and equipment operating parameters based on the data fed back from the sensors to ensure the stability of the treatment effect. For example, if the concentration of heavy metal ions exceeds the standard, the system will automatically increase the dosage of reagents or extend the treatment time.

[0004] In practical applications, the addition of chemical treatment agents is a crucial step. However, manual dosing relies on the operator's experience and judgment, which leads to variations in dosage and timing, thus affecting treatment effectiveness, increasing the risk of human error, interfering with intelligent monitoring systems, and impacting the accuracy of monitoring results.

[0005] Single-unit dosing pumps suffer from insufficient precision and inconvenient adjustment. Due to pump performance limitations, it is difficult to accurately control the dosage, which may lead to poor treatment results or waste of chemicals. In addition, single-unit dosing pumps lack flexibility in dealing with different water qualities and treatment needs, making it difficult to meet diverse treatment requirements.

[0006] The low integration of the dosing system led to interference with the device's monitoring. Manual dosing and single-unit dosing pumps resulted in significant fluctuations in water quality parameters, increasing the complexity of the monitoring system. Furthermore, bottlenecks in information transmission and processing affected the real-time performance and accuracy of intelligent monitoring, limiting the full utilization of the device's capabilities.

The device includes a chemical reaction sedimentation tank 1, a filter tank 2, a filter membrane tank 3, an inlet pipe 5, and heavy metal detection instruments 6. These components are sequentially mounted on a support frame from one end to the other, and the tanks are tightly connected by connecting pipes. The inlet pipe 5 is located on the side wall of the chemical reaction sedimentation tank 1, and heavy metal detection instruments 6 are installed on the inlet pipe 5 and the connecting pipe. These instruments can perform multi-stage detection on the treated liquid to ensure that the heavy metal content meets safety standards.

[0029] The upper side walls of the chemical reaction sedimentation tank 1, filter tank 2, and filter membrane tank 3 are equipped with connectors 7, which are connected to inlet pipes 9 via chemical liquid separation pipes 8. Inlet pipes 9 are connected to dosing pumps 10, which are responsible for quantitatively adding different chemical treatment agents into the chemical reaction sedimentation tank 1, filter tank 2, and filter membrane tank 3 to achieve precise addition of different chemical treatment agents.

[0030] The dosing pump 10 is connected to a chemical tank 15 and a water inlet 12 via a pipeline, allowing the input of different chemical treatment agents and liquids. A flow meter 13 is installed on the pipeline between the water inlet 12 and the chemical tank 15, which can precisely control the dosing amount to ensure accurate addition of the chemical treatment agent.

[0031] The stirring assembly 4 includes a stirring motor, a stirring rod, and stirring blades. The stirring blades are mounted on the stirring rod, which is bolted to the output end of the stirring motor. The stirring motor is bolted to the sealing cover at the top of the chemical reaction precipitation tank 1 and the filter tank 2, and a mechanical seal is achieved between the motor and the sealing cover to ensure airtightness during the stirring process.

[0032] The filter tank 2 has multiple filter layers installed in the middle, including a PP cotton filter layer, a pebble layer, a gravel layer, and an activated carbon layer. These filter layers can effectively remove suspended solids and some organic matter from the wastewater. The membrane filter tank 3 is equipped with one or more of the following membrane types: hollow fiber membrane, reverse osmosis membrane, and ultrafiltration membrane. These membranes can further remove fine particles and dissolved pollutants from the wastewater.

[0033] The chemical reaction sedimentation tank 1, filter tank 2, and membrane filter tank 3 are equipped with inspection ports on their walls. These ports are fitted with sealing covers using bolts, and sealing rings are installed at the connections to ensure a tight seal during maintenance. Each of the three tanks has a drain tank at its lower end. Adjacent tanks are connected by pipes, allowing wastewater to pass sequentially through these tanks to complete the filtration process.

[0034] The chemical dispensing pipeline 8 is connected to the connector 7 via a connecting flange and to the inlet pipeline 9. Each dosing pump 10 is connected to the chemical dispensing pipeline 8 via the inlet pipeline 9. Each inlet pipeline 9 is equipped with an electrically controlled valve, which allows different chemical treatment agents to be introduced into different tanks, ensuring the correct dosing of the chemical treatment agents.

[0035] The tank body of the chemical tank 15 is equipped with a replenishment port, through which the chemical treatment agent inside the tank 15 can be replenished. A controller 14 is installed above the dosing pump 10. The controller 14 is connected to the instruments and valves via wires to realize intelligent control of the entire device, ensuring the high efficiency and stability of the filtration process.

[0036] Turn on controller 14 and ensure all components are operating normally. Open inlet 12 to allow wastewater to enter the device. Flow meter 13 ensures the inflow rate reaches the set value. Add chemical treatment agent to the device through tank 15 and inlet 12. Flow meter 13 precisely controls the dosage to ensure accurate addition. Dosing pump 10 delivers the chemical treatment agent to chemical reaction sedimentation tank 1 through inlet pipe 9 and liquid distribution pipe 8. Agitator assembly 4 (agitator motor, agitator rod, and agitator blades) starts operating to ensure thorough mixing of the chemical treatment agent and wastewater. Heavy metals in the wastewater react with the chemical treatment agent to form precipitates.

[0037] After sedimentation, the wastewater enters filter tank 2 through a connecting pipe. The multi-layered filtration system in filter tank 2 (PP cotton filter layer, pebble layer, gravel layer, activated carbon layer) removes suspended solids and some organic matter from the wastewater. The filtered wastewater then continues through the connecting pipe into membrane filter tank 3. The hollow fiber membrane, reverse osmosis membrane, and ultrafiltration membrane in membrane filter tank 3 further remove fine particles and dissolved pollutants from the wastewater. Heavy metal detector 6 performs multi-stage testing on the treated liquid to ensure that the heavy metal content meets safety standards. Wastewater that passes the test is discharged through the drain port. Regularly inspect and maintain the inspection ports of each tank to ensure sealing. If maintenance is required, open the inspection port and operate using bolts and sealed inspection covers. Controller 14 connects to instruments and valves via wires to achieve intelligent control of the entire device. Electrically controlled valves allow different chemical treatment agents to be input into different tanks, ensuring correct chemical dosing. This intelligent monitoring wastewater heavy metal filtration device efficiently removes heavy metals from wastewater, ensuring that the discharged water meets environmental standards.
