Technical Field

[0001] The invention relates to the technical field of environmentally friendly filtration, and in particular to an environmentally friendly intelligent water supply and purification filtration method. Background Art

[0002] Water treatment methods include physical treatment and chemical treatment. Humans have been treating water for many years. Physical methods include using filter materials with different pore sizes to remove impurities from the water by adsorption or barrier methods. The most important adsorption method is adsorption with activated carbon. The barrier method is to pass water through the filter material so that larger impurities cannot pass through, thereby obtaining cleaner water. In addition, physical methods also include precipitation methods, which is to let impurities with smaller specific gravity float on the water surface and be fished out, or to let impurities with larger specific gravity settle below and then obtain water. Chemical methods use various chemicals to convert impurities in the water into substances that are less harmful to the human body, or to concentrate impurities. The oldest chemical treatment method should be to add alum to the water. After the impurities in the water are gathered and the volume increases, the impurities can be removed by filtration.

The present invention also discloses a corresponding integrated water purification and supply system. The present invention optimizes the configuration of the system to the greatest extent, ensures the treatment effect, and greatly saves the total investment and operating costs, and improves the promotion and application in the water treatment industry.

[0146] Embodiment 1:

[0147] First, the raw water enters the high-efficiency cyclone desander, where the large particles of impurities are initially separated and removed, and the treated water flows out to the next step.

[0148] The water flowing out of the high-efficiency cyclone desander enters the precision bag filter 3, and further filters the tiny particles and suspended matter. The water treated by the precision bag filter 3 continues to flow to the security precision filter 4.

[0159] Its function is to initially remove large particles of impurities larger than 0.1mm in the water. After the raw water enters the cyclone desander, under the action of specific hydrodynamic principles, large particles of impurities move to the wall of the device due to centrifugal force and are discharged through the sand discharge port at the bottom, thus completing the initial purification of the raw water;

[0160] Precision bag filter 3

[0161] The water that has been preliminarily treated by the cyclone desander enters the precision bag filter 3 to further filter out the 5μm tiny particles and suspended solids.

[0172] Automatic monitoring of pressure tank 8
