[0016] 2.

[0017] When the turbidity and permanganate index of the raw water are high, close the mud discharge valve and the clean water outlet valve, open the overflow valve and the raw water inlet valve, and the raw water enters the raw water tank from the raw water inlet pipe.

[0018] 3. When the particle density in the raw water is unstable, select operation mode 1: the raw water or the water purified by the water purifier enters the corridor inlet of the secondary centrifugal corridor in the first centrifugal purification zone from the corridor outlet of the primary centrifugal corridor in the first centrifugal purification zone, and then enters the corridor inlet of the tertiary centrifugal corridor in the first centrifugal purification zone from the corridor outlet of the secondary centrifugal corridor in the first centrifugal purification zone, and then enters the corridor inlet of the tertiary centrifugal corridor in the second centrifugal purification zone from the corridor outlet of the tertiary centrifugal corridor in the first centrifugal purification zone, and then enters the corridor inlet of the secondary centrifugal corridor in the second centrifugal purification zone from the corridor outlet of the tertiary centrifugal corridor in the second centrifugal purification zone, and then enters the corridor inlet of the primary centrifugal corridor in the second centrifugal purification zone from the corridor outlet of the secondary centrifugal corridor in the second centrifugal purification zone, and finally enters the water distribution zone from the corridor outlet of the primary centrifugal corridor in the second centrifugal purification zone;

[0042] An operating method of a high-efficiency agricultural drinking water treatment equipment, the operating method is as follows:

[0043] 1. Determine the turbidity, permanganate index and particle density stability of raw water;

[0044] 2. When the turbidity and permanganate index of the raw water are low, close the mud discharge valve 25 and the clean water outlet valve 32, open the overflow valve 5 and the raw water inlet valve 2, and the raw water enters the raw water tank 4 from the raw water inlet pipe 1. Adjust the three-way control valve 7 to make the raw water flow into the raw water distribution pipe 16, and adjust the four-way control valve 17 to guide the raw water into the first centrifugal purification area;

[0045] When the turbidity and permanganate index of the raw water are too high, close the mud valve 25 and the clean water outlet valve 32, open the overflow valve 5 and the raw water inlet valve 2, and the raw water enters the raw water tank 4 from the raw water inlet pipe 1. Adjust the three-way control valve 7 and the four-way control valve 17 to prevent the raw water from entering the raw water distribution pipe 16. Adjust the three-way control valve 7 to allow the raw water to flow into the water purifier mixing pipe 15. At the same time, adjust the four-way control valve 17 to introduce the raw water into the first centrifugal purification area. At the same time, open the valve 9, and introduce the water purifier from the dosing pipe 8 to mix with the raw water. According to the water quality, the water purifier can be selected from food-grade water purifiers such as liquid polyaluminum chloride or potassium permanganate. Adjust the opening degree of the flow control ball valve 10, the flow control ball valve 2 11, the flow control ball valve 3 12, the flow control ball valve 4 13 and the flow control ball valve 5 14 respectively. The initial opening degrees of valve 5 14 are 70%, 100%, 70%, 100%, and 70% respectively, which control the opening degrees of flow control ball valve 10 to flow control ball valve 5 14 respectively, adjust the change of water flow velocity, thereby producing continuous flow velocity changes in the water purification agent mixing tube 15, which is conducive to the mixing of the agents; the opening degree can be optimized and adjusted according to the actual treatment effect; with the opening angle of zero degree as fully open and the opening angle of 90 degrees as fully closed, the opening angles of flow control ball valve 10 to flow control ball valve 5 14 are 45°→0°→45°→0°→45° respectively, and can also be set to 30°→0°→30°→0°→30°, and can also be set to 45°→0°→30°→0°→45°; different settings are adopted according to different raw water quality conditions to achieve the best mixing flocculation reaction effect;

[0046] 3. When the particle density in the raw water is unstable, select operation mode 1: the raw water or the water purified by the water purifier enters the corridor inlet of the secondary centrifugal corridor 21 in the first centrifugal purification area from the corridor outlet of the primary centrifugal corridor 20 in the first centrifugal purification area, and then enters the corridor inlet of the tertiary centrifugal corridor 22 in the first centrifugal purification area from the corridor outlet of the secondary centrifugal corridor 21 in the first centrifugal purification area, and then enters the corridor outlet of the tertiary centrifugal corridor 22 in the first centrifugal purification area. Enter the corridor water inlet of the third-stage centrifugal corridor 22 in the second centrifugal purification area, then enter the corridor water inlet of the second-stage centrifugal corridor 21 in the second centrifugal purification area from the corridor water outlet of the third-stage centrifugal corridor 22 in the second centrifugal purification area, then enter the corridor water inlet of the first-stage centrifugal corridor 20 in the second centrifugal purification area from the corridor water outlet of the second centrifugal corridor 21 in the second centrifugal purification area, and finally enter the water distribution area 28 from the corridor water outlet of the first-stage centrifugal corridor 20 in the second centrifugal purification area; that is, according to Figure 4 and 5 The ABCDEFJHIJKL flow sequence is shown in the figure; when the operation mode 1 is adopted, the radius of the centrifugal corridor in the first centrifugal purification zone decreases from the outside to the inside, and the centrifugal force increases successively, so that the particles in the water with density from large to small can be removed successively; after entering the second centrifugal purification zone, the radius of the centrifugal corridor increases successively, and the centrifugal force decreases successively, which avoids the excessive shear force when the water flows out of the second centrifugal purification zone and enters the water distribution zone on the basis of ensuring the centrifugal purification effect, and ensures the sedimentation purification effect in the water distribution zone and the steady flow zone; this operation mode is suitable for water quality with obvious colloidal coagulation reaction and unstable particle density during the water purification process.
