[0020] Example 1 See attached document Figure 1-6This application provides a wastewater reaction tank for easy sampling and testing, including a reaction tank 1 and a dosing tank, and a control box for controlling the operation of electrical components. The reaction tank 1 is equipped with a pressure relief valve and a pressure gauge 2. The reaction tank 1 is equipped with an inlet pipe 3 and a first clean water pipe 4. The bottom of the reaction tank 1 is equipped with a drain pipe 5. The inlet pipe 3 is connected to a municipal sewage pipeline through an inlet pump, which pumps wastewater into the reaction tank 1 for treatment. The clean water pipe is located at the bottom of the reaction tank 1 for discharging the treated clean water. The drain pipe 5 is used to discharge wastewater residue and other contaminants. The dosing tank includes a first dosing tank 6 and a second dosing tank 7. Both the first dosing tank 6 and the second dosing tank 7 are equipped with a stirring motor 23, which is connected to an agitator. A stirring shaft is used to stir the liquid medicine in the dosing tank evenly, facilitating a thorough reaction in the subsequent reaction tank 1. The first dosing tank 6 is connected to the water inlet pipe 3 via a first dosing pipe 8, and the second dosing tank 7 is connected to the water inlet pipe 3 via a second dosing pipe 9. Both the first and second dosing pipes are equipped with valves that open when dosing is required and close when no dosing is needed. The first dosing pipe 8 is positioned below the second dosing pipe 9, with a suitable distance between them. Both the first and second dosing tanks 6 and 7 are equipped with air pumps to aerate the tanks, propelling the liquid medicine into the reaction tank 1. Alternatively, a water pump can be used to pump the liquid medicine into the reaction tank 1. A first sampling component 10 is staggered on the water inlet pipe 3. The first sampling component 10 is located between the first dosing tube 8 and the second dosing tube 9, and is used to sample the mixture at the first dosing tube 8. The second sampling component 11 is located above the second dosing tube 9 and is used to sample the mixture at the first dosing tube 8 and the second dosing tube 9. Both the first sampling component 10 and the second sampling component 11 include an arc tube 12, a cross tube 13, a top cover 14, a spring 15, a plunger 16, and a sampling bottle 17. The two ends of the arc tube 12 are connected to the water inlet pipe 3. The arc shape of the arc tube 12 facilitates liquid flow, reduces liquid accumulation, and makes the sampling results more accurate. The left end of the cross tube 13 is connected to the arc tube 12, and the right end of the cross tube 13 is connected to the arc tube 12. The cross tube 13 is sealed from top to bottom. The cross tube 13 has a countersunk hole 18 that mates with the plunger 16. The upper cover 14 is threaded to the upper end of the cross tube 13 for easy disassembly. One end of the spring 15 is fixed to the upper cover 14, and the other end is fixed to the plunger 16. The cross tube 13 has a first sealing ring 19. The neck of the sampling bottle 17 has a liquid inlet 20. The outer diameter of the neck of the sampling bottle 17 matches the outer diameter of the lower opening of the cross tube 13. The lower opening of the cross tube 13 has a second sealing ring 39 to prevent leakage. The upper part of the countersunk hole 18 has a first chamfer 21, and the bottom of the plunger 16 has a second chamfer 22 to facilitate the plunger 16 entering the countersunk hole 18. Wastewater is pumped in through the inlet pipe 3.After being added through the first dosing pipe 8 and the second dosing pipe 9, the chemicals flow into the reaction tank 1 for treatment. After treatment, clean water is discharged from the clean water pipe, and residual chemicals are discharged from the drain pipe 5 for collection and treatment. During sampling, the technician holds the sampling bottle 17 and pushes it upwards, aligning it with the lower opening of the cross tube 13. This causes the sampling bottle 17 to push the plunger 16 upwards, disengaging the plunger 16 from the bottom surface of the sinkhole 18. This connects the inlet 20 of the sampling bottle 17 with the wastewater mixture in the cross tube 13, allowing the wastewater mixture to enter the sampling bottle 17 through the inlet 20. The sampling bottle 17 is then removed downwards, and the plunger 16, under the elastic force of the spring 15, returns to the bottom surface of the sinkhole 18, blocking leakage and facilitating sampling.

Pressure gauges 2 are also installed on the inlet pipe 3 and the clean water pipe to detect pressure. The first backwash outlet pipe 27 is located at the top of the reaction tank 1 and is connected to the drain pipe 5. For simplicity, the first backwash pipe 26 and the first backwash outlet pipe 27 are connected to the drain pipe 5. All the backwash outlet pipes 27 are connected to the drain pipe 5. The drain pipe 5 is equipped with a solenoid valve 31 that separates the first backwash pipe 26 and the first backwash outlet pipe 27. The first backwash pipe 26 is equipped with a solenoid valve 31. When backwashing is required, the solenoid valve 31 on the first backwash pipe 26 is opened to connect the pipeline, and the solenoid valve 31 on the drain pipe 5 is closed to separate them. The first water pump 25 is driven to pump the clean water in the clean water tank 24 into the reaction tank 1 from the bottom through the first backwash pipe 26 for backwashing. The backwash liquid flows from the first backwash outlet pipe 27 to the drain pipe 5 for discharge, thereby cleaning the reaction tank 1.

The second clean water pipe 28 is equipped with a solenoid valve 31, which can be used to collect the clean water processed by the reaction tank 1 for backwashing, thereby saving water resources.

[0023] Preferably, the backwashing system further includes a second backwash pipe 30 and a second water pump. The second water pump is a high-pressure water pump. The second backwash pipe 30 is connected to the clean water tank 24 and the reaction tank 1 through the second water pump. The second backwash pipe 30 is equipped with a solenoid valve 31. During backwashing, in order to improve the cleaning effect, a high-pressure water pump is used to perform a second backwash to improve the backwashing effect. Specifically, the second backwash pipe 30 is connected to a third backwash pipe 34, which is connected to the reaction tank 1. The diameter of the third backwash pipe 34 is smaller than that of the second backwash pipe 30, which helps to increase the water pressure and further improve the cleaning effect. Specifically, the reaction tank 1 is equipped with a second backwash outlet pipe 32, which is connected to the drain pipe 5 to increase the drainage speed.

[0024] Specifically, the reaction tank 1 is equipped with an observation window 33 to facilitate observation of the wastewater reaction.

[0025] Specifically, the backwashing system also includes a first air pump 35, a buffer tank 36, and an air inlet pipe 37. The first air pump 35 is connected to the buffer tank 36 and electrically connected to the control box. The buffer tank 35 is connected to the air inlet pipe 37, which is connected to the reaction tank 1. The buffer tank 36 is used for noise reduction and to prevent liquid backflow in the reaction tank 1. The air inlet pipe 37 is equipped with a solenoid valve 31. Air is supplied by the first air pump 35 to perform air washing on the reaction tank 1. The combination of water washing and air washing improves the cleaning efficiency and effect.
