[0021] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0022] See Figures 1 to 3 This utility model provides an automated deep water treatment system suitable for hospitals, including a water quality detector 1 and the hospital's existing sewage pretreatment equipment 2. The outlet of the sewage pretreatment equipment 2 is connected to the inlet of the water quality detector 1. The system also includes a first pipe 3, a second pipe 4, a valve 5, a dosing tank 6, and a reactor 7. The outlet of the water quality detector 1 is connected to the municipal pipe network 8 through the first pipe 3, and the outlet of the water quality detector 1 is connected to the inlet of the reactor 7 through the second pipe 4. The valve 5 is installed between the water quality detector 1 and the first pipe 3 and the second pipe 4, respectively. The dosing tank 6 is connected to the second pipe 4 through a dosing pipe 9. The dosing tank 6 is located upstream of the reactor 7, and the valve 5 is also installed on the dosing pipe 9. The outlet of the reactor 7 is connected to the municipal pipe network 8 through a drain pipe 10.

[0023] During the water treatment process, the outlet of the hospital's original sewage pretreatment equipment 2 is connected to the water quality detector 1. When the effluent passes through the water quality detector 1, it is tested. If the new pollutants such as antibiotics in the water do not exceed the standard, the water quality detector 1 automatically opens the valve 5 of pipe 1 3 and closes the valve 5 of pipe 2 4, allowing the effluent to be discharged directly into the municipal pipe network 8 through pipe 1 3. If the new pollutants such as antibiotics in the water exceed the standard, the water quality detector 1 automatically opens the valve 5 of pipe 2 4 and closes the valve 5 of pipe 1 3, while simultaneously opening the valve 5 of the dosing pipe 9. Through the pump body of the dosing tank 6, the oxidant solution containing persulfate inside the dosing tank 6 flows from the dosing pipe 9 into pipe 2 4. The aqueous solution containing the new pollutants and the oxidant solution enter the reactor 7 through pipe 2 4 and mix evenly. Secondary purification is carried out in the reactor 7, and finally the effluent is discharged into the municipal pipe network 8 through the drain pipe 10.

[0024] This device features a high degree of automation, simple operation, and reasonable design. It can be quickly applied to the upgrading and renovation of existing wastewater pretreatment facilities and equipment in hospitals, greatly enhancing the removal capacity for new pollutants such as antibiotics.

[0025] The valve 5 is a solenoid valve. The water quality detector 1 is also equipped with a commercially available STM32 series microcontroller. The controller is electrically connected to both the water quality detector 1 and the valve 5. The water quality detector 1 feeds back the detection results to the controller, which opens or closes either pipe 3 or pipe 4 according to the preset parameters. When the detection results meet the parameters, the controller opens valve 5 of pipe 3 and closes valve 5 of pipe 4, allowing the effluent to be discharged directly into the municipal pipe network 8 through pipe 3. When the detection results do not meet the parameters, the controller opens valve 5 of pipe 4 and closes valve 5 of pipe 3, while simultaneously opening valve 5 of the dosing pipe 9, allowing the wastewater and oxidant to enter the reactor 7 through pipe 4 for mixing and further purification. The water quality detector 1, solenoid valve, and dosing tank 6 are all existing mature products, and suitable models can be purchased online or offline according to requirements.

[0026] The reactor 7 includes a hollow shell. A lower grid 11 and a middle grid 12 are longitudinally arranged within the shell. The lower and middle grids 11 and 12 are evenly distributed with mesh for water flow. The lower and middle grids 11 and 12 divide the interior of the shell into interconnected lower, middle, and upper treatment chambers. Pipe 4 communicates with the lower treatment chamber, and drain pipe 10 communicates with the upper treatment chamber. Each of the lower, middle, and upper treatment chambers contains packing materials for water purification. Different packing layers are separated by grids. The grids prevent the lower packing materials from moving upwards due to water flow and ensure that the upper packing materials do not fall to the lower layer.

[0027] The filling material for the lower processing chamber is 200-mesh quartz sand.

[0028] The oxidation reaction zone of the middle layer treatment chamber is the core area of ​​reactor 7. The packing material is a mixture of coffee grounds biochar and 200-mesh quartz sand, which contains 50-100 mg of coffee grounds biochar.

[0029] Coffee grounds biochar is prepared by collecting coffee grounds, preliminarily washing and drying them, and then mixing them with an appropriate amount of metal salt solution before calcination. Specifically, the coffee grounds are preliminarily washed with ultrapure water and ethanol, dried at 60°C for 72 hours, and then 0.015 mol of ferrous sulfate and 0.015 mol of manganese chloride are dissolved in 50 mL of deionized water. 5 g of coffee grounds are then added, and the mixture is stirred at room temperature for 12 hours. The mixture is then dried in a 60°C oven for 24 hours. The dried material is placed in a quartz boat and calcined at a high temperature of 700°C under a N2 atmosphere at a heating rate of 10°C / min for 2 hours. After cooling to room temperature, coffee grounds biochar is obtained.

[0030] The filler material of the upper processing chamber is soft fiber.

[0031] The lower treatment chamber of reactor 7 is designed with an inlet at the bottom, allowing wastewater to directly contact the packing material in the lower treatment chamber. The lower treatment chamber uses 200-mesh quartz sand as packing material, which helps to evenly distribute the water flow, reduce hydraulic impact, and make the water quality more stable during the chemical oxidation reaction zone of the middle treatment chamber, while also initially filtering large particulate impurities. The middle layer uses a mixture of coffee grounds biochar and 200-mesh quartz sand as packing material to activate persulfate and generate highly oxidizing active substances, accelerating the decomposition of organic pollutants in the water and improving water treatment efficiency. The upper layer is arranged with soft fiber packing material, increasing the contact opportunities between active oxidants and pollutants in the water, thereby improving the interception efficiency and intercepting small solid particles.

[0032] The reactor 7 is a detachable reactor. The shell includes a lower circular tube 13, a middle circular tube 14, and an upper circular tube 15 corresponding to the lower, middle, and upper processing chambers. Adjacent circular tubes are detachably connected by flanges. The lower grid 11 is fixed to the top of the lower circular tube 13, and the middle grid 12 is fixed to the top of the middle circular tube 14. The inner diameter of the circular tubes is uniform, ranging from 5 to 15 cm. The length of the upper / lower circular tube 13 is 20 to 50 cm, and the length of the middle circular tube 14 is 5 to 10 cm. The detachable shell and grid facilitate subsequent maintenance.

[0033] The upper circular pipe 15 is also provided with a vent 16 on its side wall, and the vent 16 is located above the drain pipe 10.

[0034] A movable grille 17 is rotatably mounted on the top of the lower grille 11. The movable grille 17 also has evenly distributed mesh for water flow. A top cover 18 is provided on the top of the housing, and an adjustment knob 19 is rotatably mounted on the top of the top cover 18. An adjustment shaft 20 is located inside the housing. The bottom of the adjustment shaft 20 passes through the middle grille 12 and is coaxially connected to the movable grille 17. The top of the adjustment knob 19 passes through the top cover 18 and is coaxially connected to the adjustment knob 19. The adjustment shaft 20 is rotatably connected to both the middle grille 12 and the top cover 18. By adjusting the knob 19, the adjustment shaft 20 can rotate the movable grille 17, causing the meshes of the movable grille 17 and the lower grille 11 to interweave, thereby adjusting the mesh density and helping to control the flow rate and dispersion of water entering from the bottom of the middle treatment chamber.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
