[0037] Embodiment 1

[0038] refer to Figure 1 The high-precision adaptive water treatment and filtering device for reducing suspended solids described in the present invention comprises an inlet pipe 110, an inlet valve 1, an inlet main channel 8 and an inlet branch channel 9; the outlet of the inlet pipe 110 is connected to the inlet of the inlet main channel 8 via the inlet valve 1, and each inlet branch channel 9 is respectively connected to the outlet of the inlet main channel 8, and the outlet of the inlet branch channel 9 is connected to the inlet of the filter tank via the overflow weir 10.

[0039] The filter pool includes a filter pool shell, in which a water inlet hole 11, a filter material intercepting cover plate 6 and a filter layer are arranged, wherein the water inlet hole plate 11, the filter material intercepting cover plate 6 and the filter layer are distributed in sequence from top to bottom, and a plurality of water inlet holes 20 are arranged on the water inlet hole plate 11, and the filter layer includes a fiber filter layer 14, a filter material supporting layer 15 and a module filter plate 16 arranged in sequence from top to bottom, and a drainage groove 21 is arranged on the side of the filter pool shell, wherein the drainage groove 21 is connected to the area between the filter material intercepting cover plate 6 and the water inlet hole plate 11, and the bottom of the filter layer is connected to the water distribution area 18 through a plurality of elastic air injection filter heads 12, and the water distribution hole 13 of the water distribution area 18 is connected to the entrance of the water outlet channel 22 through the multifunctional pipe 115, the water outlet valve 2 and the water seal pool 19, and the water outlet channel 22 is connected to the water outlet pipe 111, and the water outlet pipe 111 is provided with a flow sensor 101 and an online turbidity meter 102.

[0040] The outlet of the water outlet pipe 111 is connected to the water distribution area 18 via the backwash water inlet main pipe 116 and the backwash water inlet valve 5 , and the backwash air inlet pipe 114 is connected to the water distribution area 18 via the backwash air inlet valve 4 and the air injection pipe group 23 .

[0041] It should be noted that the elastic air injection filter head 12 is installed on the installation hole on the filter material interception cover plate 6.

[0042] The water distribution area 18 is connected to a second backwash drain pipe 113 , and the first backwash drain pipe 112 is connected to a drain port on the filter tank shell, and the drain port is located between the filter layer and the filter material interception cover plate 6 .

[0043] The advantage of setting the overflow weir 10 is that it can ensure that the water inflow of each filter tank is consistent and is not affected by the water level fluctuation in the filter tank. Under the action of gravity, the filtered water enters the water distribution area 18 at the bottom of the filter tank through the elastic air jet filter head 12, and finally overflows to the outlet channel 22 through the water seal tank 19 for discharge.

[0044] Accordingly, the high-precision adaptive water treatment and filtration method for reducing suspended matter of the present invention comprises the following steps:

[0045] The specific operation of flushing is as follows: close the water inlet valve 1 and the water outlet valve 2, open the backwashing sewage valve 3, the backwashing air inlet valve 4, and the backwashing water inlet valve 5, the water level in the pool drops below the top of the drainage groove 21, open the water inlet valve plate 7, wait for the filtered water to enter the filter pool from the water inlet hole 20, sweep and wash the surface of the filter material, and flush the impurities on the surface of the filter layer into the drainage groove 21. In the air flushing stage, air enters through the backwashing air inlet valve 4, then enters the water distribution area 18 through the air injection pipe group 23, and finally sprays out through the elastic air injection filter head 12 into the filter material layer. The impurities on the surface of the filter material are scrubbed off and suspended in the water, and are flushed into the drainage groove 21 by the surface sweeping water. In the latter stage of air flushing, open the backwashing water inlet valve 5, and the air and water flow into the water distribution area 18 through the air injection pipe group 23 and the water distribution hole 13 respectively, and enter the filter pool evenly through the elastic air injection filter head 12, the filter material is further flushed, and the surface sweeping continues. The device is provided with air injection pipe groups 23 at the bottom, side and front of the filter material layer, so that the process of washing the filter material can be made more uniform.

[0046] Among them, it should be noted that the flushing process adopts a gas-water combined and automatically controlled method, and is controlled by an automatic control system, and is carried out in the order of first air flushing, then air and water flushing, and finally water flushing.

[0047] The water inlet pipe 110 and the water outlet pipe 111 are provided with a flow sensor 101 and an online turbidity meter 102 for online monitoring of the water inlet flow and turbidity. The above instrument signals are connected with the filter and flushing link for air-water combined adaptive filtration control.

[0048] The process of air-water combined adaptive filtration control is:

[0049] 1) Collecting water flow and turbidity online through the flow sensor 101 and the online turbidity meter 102;

[0050] 2) According to the monitoring data, the opening of the water inlet valve plate is automatically controlled to distribute the water inlet to each filter pool to ensure the stability of the water inlet.

[0051] 3) The process water flows into the fiber filter layer, and impurities are filtered out by gravity. The filtered water enters the water distribution area 18 through the elastic air jet filter head 12 and is discharged to the outlet channel 22.

[0052] 4) Calculate the pollution capacity of the filter layer N(t) based on the real-time monitoring data. At the same time, draw the filter pollution curve to determine whether the critical value N is reached. crit to determine if backwashing is necessary.

[0053] 5) Air-water combined flushing: When the amount of pollutants reaches the critical value N crit When the backwashing process is started automatically, the backwashing process is performed in sequence, that is, the air flushing, air-water flushing and water flushing are performed to clean the impurities in the filter material layer and discharge them into the drainage tank 21;

[0054] 6) Monitor the turbidity of the effluent in real time and automatically adjust the filtration and backwashing frequency according to the water quality data to ensure stable and reliable filtration effect.

[0055] Assume that the water volume of the filter tank is Q(t), the turbidity of the water is T(t), the pollution capacity of the filter material is N(t), and the critical value of the pollution capacity of the filter material is N crit ;

[0056] The mass of pollutants entering the filter per unit time is:

[0057] m(t)=Q(t)×T(t)×k

[0058] Among them, k is the conversion coefficient, which is used to convert the product of turbidity and water volume into the mass of pollutants. The k coefficient depends on factors such as the nature and density of pollutants in the water and needs to be determined through experiments or empirical data.

[0059] The dirt holding capacity of the filter material N(t) is:

[0060]

[0061] When N(t)≥N crit When the pollution holding capacity of the filter media has reached or exceeded the critical value, the filter tank needs to be flushed.

[0062] When N(t)<N crit The filter material can continue to work normally.

[0063] It should be noted that the present invention has the following characteristics:

[0064] The present invention is equipped with a water inlet main channel, which is connected with each filter tank through a water inlet gate plate, thereby constructing a controllable partition filtering system.

[0065] The air injection pipe group 23 is arranged in the air distribution area and is configured in multiple stages. In the backwashing stage, even if the water volume remains unchanged, the filter layer can be completely washed clean, which effectively solves the problem that the filter material of the traditional filter tank cannot be evenly washed.

[0066] The present invention is designed with the function of automatically supervising and controlling the water volume and backwashing frequency. In the absence of human supervision, the filtering and backwashing frequencies can be intelligently adjusted according to the water quality conditions, thereby achieving controllability of the filtering process and ensuring a stable water output effect.

[0067] In the present invention, the filter material is a fiber filter material with both adsorption and pollution interception performance. The fiber filter material has a difference in specific gravity between the head and the tail. The filter material will generate a large mechanical force with the backwash water flow, and has a high removal rate for impurities such as suspended matter and colloids in water, and a large amount of pollution. The filter material is small in size, which has little effect on the uniformity of the porosity distribution of the filtering section, thereby improving the pollution interception capacity.

[0068] In the present invention, the elastic air jet filter head 12 is made of elastic material and has an adaptive aperture adjustment function. When the pressure in the filter tank changes or the resistance of the filter material layer changes, the aperture of the filter cap can be automatically adjusted to maintain a stable filtering speed and effect, while preventing the filter material from entering the filter head and causing blockage.

[0069] Furthermore, the module filter plate 16 is made of a porous PP injection molded plate, which is located above the water distribution area and has holes distributed in a mesh shape. The elastic air jet filter head 12 is installed on the module filter plate 16, and the module filter plate 16 is covered with a layer of filter screen plate through reinforcing ribs, and the filter screen plate is also made of PP injection molded plate. The fiber filter material is placed on the filter screen plate, so that the gas distribution is achieved twice for the filter material layer. This allows the gas to be evenly distributed during the backwashing process and is not affected by the flushing intensity, thereby ensuring that the filter material is flushed clean.
