[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 , the present invention provides an efficient adsorption and filtration method for producing pure drinking water, including the following steps:

[0037] S1: Collect the raw water required for production, and preliminarily remove the suspended solids in the raw water through a pretreatment process;

[0038] S2: Adsorb and filter the raw water after the pretreatment process through a water treatment filtration device to secondarily remove the remaining part of the suspended solids and organic substances in the raw water;

[0039] S3: Detect the water turbidity of the raw water after the rapid filtration process through a first detection process, and correct the current treatment time of the rapid filtration process in step S2 according to the detection result until the detection result meets the preset water turbidity value;

[0040] S4: Remove ions, organic compounds or other dissolved solids in the raw water that meet the detection requirements of the first detection process through a reverse osmosis treatment process;

[0041] S5: Detect the suspended solid content in the raw water after the reverse osmosis treatment process through a second detection process, and adjust the operating pressure of the reverse osmosis treatment process in step S4 according to the detection result until the detection result meets the preset suspended solid content value;

[0042] S6: Adjust the pH value of the raw water that meets the requirements of the second detection process through pH adjustment resin so that it meets the pH value required for drinking water;

[0044] In this alternative embodiment, in step S3, the turbidity sensor is used to detect the turbidity of the raw water after the rapid filtration process, and the detected water body turbidity is used as the determined turbidity value for comparison with the preset water body turbidity value. If the determined turbidity value is less than or equal to the preset water body turbidity value, there is no need to correct the treatment time of the rapid filtration process, and the first preset treatment time is directly used as the current treatment time of the rapid filtration process. Otherwise, it is calculated according to the determined turbidity value, the preset water body turbidity value, and the first preset treatment time to obtain the corrected filtration time;

If the suspended solid determination value is less than or equal to the preset suspended solid content value, there is no need to correct the operating pressure of the reverse osmosis treatment process, and the preset operating pressure is directly used as the actual operating pressure of the current reverse osmosis treatment process. Otherwise, it is calculated according to the suspended solid determination value and the preset suspended solid content value to obtain the correction coefficient of the operating pressure, and then calculated according to the correction coefficient of the operating pressure and the preset operating pressure to obtain the corrected operating pressure as the actual operating pressure of the current reverse osmosis treatment process;
