[0020] Open the second electronic valve at the raw water inlet through the side switch, and close the fourth electronic valve at the backwash water outlet at the bottom of the filtration and disinfection bin;

[0021] Under the action of the intake water pump, the raw water enters the water inlet pipe from the raw water inlet, and the raw water enters the flocculation and stirring bin, and the preliminary purification of the raw water is realized through flocculation and stirring; the motor drives the rotating shaft to rotate slowly, the air compressor blows air along the air inlet pipe, and the air enters the large air flotation stirring fan blade and the small air flotation stirring fan blade in turn along the internal space of the rotating shaft, and air is blown into the water body through many air flotation holes uniformly arranged on the surfaces of the large air flotation stirring fan blade and the small air flotation stirring fan blade, combining flocculation stirring with air flotation; the stirring of the large air flotation stirring fan blade and the small air flotation stirring fan blade accelerates the mixing between the raw water and the flocculant, strengthens the flocculation effect, improves the removal efficiency of pollutants such as particulate matter and oil in the raw water, and reduces the load for subsequent sedimentation and filtration; the small bubble air blown in through the air flotation holes wraps the tiny particles in the raw water and floats them up, forming floating slag at the top of the liquid level in the flocculation and stirring bin, and then the floating slag is scraped into the slag collecting trough by the slag scraping plate, and the floating slag is temporarily stored in the slag collecting box;

[0022] The raw water after flocculation and air flotation enters the sedimentation tank inlet pipe in the sedimentation tank through the flocculation water outlet pipe at the top of the flocculation and stirring bin, and the sludge pipe at the lower part of the flocculation and stirring bin recovers the sludge for reuse; the raw water after flocculation and air flotation enters the trapezoidal water distribution area through the sedimentation tank inlet hole above the sedimentation tank inlet pipe, and then evenly enters the sedimentation tank through the water distribution holes on the top plate of the trapezoidal water distribution area; the inverted V-shaped water distribution cover above the water distribution holes in each trapezoidal water distribution area makes the inlet water flow into the sedimentation tank evenly, reducing the impact of the inlet water on the sedimentation area and improving the sedimentation efficiency; the V-shaped mud baffle and the sedimentation tank mud collecting trough arranged at the bottom of the sedimentation tank collect the sludge falling from the upper inclined pipe and the lower inclined pipe; the inverted V-shaped water distribution cover prevents the falling sludge from blocking the water distribution holes; the clear water after sedimentation through the upper inclined pipe and the lower inclined pipe enters the clear water bin through the overflow weir plate;

[0023] The clear water in the clear water tank enters the filtration area at the lower part of the filtration and disinfection tank through the water outlet holes of the clear water tank, and the clear water is purified again by three layers of filter plates. The purified water is evenly distributed to the disinfection area through the hole-type water distribution plate, and several equally spaced ultraviolet lamps fixedly arranged in the disinfection area perform ultraviolet disinfection on the distributed water;

[0024] Part of the purified water after disinfection enters the water quality real-time monitor in the water outlet component tank through the third electronic valve, the purified water outlet pipe and the water outlet water pump; at this time, the third electronic valve, the fifth electronic valve and the sixth electronic valve are closed through the side switch of the equipment;

At the same time, the second electronic valve at the raw water inlet is closed, and this cycle continues until the water quality of the outlet meets the standard;

[0026] The first electronic valve automatically opens when the liquid level in the filtration and disinfection tank is higher than the liquid level sensor;

[0027] During the lowest peak of the crowd's water use, the backwashing function is started; when the backwashing function is turned on, the second electronic valve at the raw water inlet is closed, and when the liquid level is lower than the liquid level sensor below the purified water outlet of the filtration and disinfection tank, the first electronic valve on the backwashing pipe connected to the water collection pipe of the pool is closed; at the same time, the fourth electronic valve at the bottom backwashing water outlet of the filtration and disinfection tank is opened through the side switch, and at the same time, the fifth electronic valve at the unqualified water outlet and the sixth electronic valve at the qualified water outlet are closed.
