Below the reagent adsorption tank 1, there is an adsorption treatment tank 2. The adsorption treatment tank 2 includes a uniform dispersion structure 3 arranged on the upper bottom surface of the inner cavity of the adsorption treatment tank 2, a number of first filter adsorption plates 4 clamped and installed on both sides of the adsorption treatment tank 2, and a second filter adsorption plate support 5 installed at the bottom of the inner cavity of the adsorption treatment tank 2. The uniform dispersion structure 3 includes a dispersion housing 6, a dispersion plate 7 arranged at the feed inlet of the dispersion housing 6, and a hole cover plate 8 hinged at the lower port of the dispersion housing 6. Above the reagent adsorption tank 1, there is an additive dispenser 9. The reagent adsorption tank 1 is convenient for the reaction of the adsorption reagent with the polluted water, aggregating the tiny heavy metals in the polluted water together. The adsorption treatment tank 2 is convenient for the adsorption treatment of the aggregated tiny heavy metals. The uniform dispersion structure 3 is convenient for evenly scattering the aggregated tiny heavy metals and the polluted water onto the first filter adsorption plate 4. The first filter adsorption plate 4 is convenient for the first filtration of the heavy metals coagulated into flocs in the polluted water, filtering the heavy metals in the polluted water as much as possible. The second filter adsorption plate support 5 is convenient for placing various targeted adsorption substances, so as to conduct targeted adsorption filtration treatment on the heavy metals in the polluted water. The dispersion housing 6 is convenient for preventing the polluted water flowing from the reagent adsorption tank 1 into the adsorption treatment tank 2 from splashing. The dispersion plate 7 is convenient for evenly scattering the polluted water flowing from the reagent adsorption tank 1 into the adsorption treatment tank 2 onto the first filter adsorption plate 4, so that the first filter adsorption plate 4 can evenly filter the polluted water, and there will be no phenomenon that the polluted water is only filtered from the middle part of the first filter adsorption plate 4. The hole cover plate 8 is convenient for the polluted water to undergo the first physical filtration and prevents larger metal particles from entering the adsorption treatment tank 2. The additive dispenser 9 is convenient for injecting the diluted adsorption additive reagent into the reagent adsorption tank 1.

[0024] Further, as Figure 1 shown in Figure 4 the figure, a first connecting pipe 10 is connected between the reagent adsorption tank 1 and the adsorption treatment tank 2. A first electric control valve 11 is arranged on the first connecting pipe 10. The reagent adsorption tank 1 and the adsorption treatment tank 2 are fixedly connected through a first connecting column 12 at the end corner. The first connecting pipe 10 is convenient for the polluted water in the reagent adsorption tank 1 to flow into the adsorption treatment tank 2 after reagent adsorption. The first electric control valve 11 plays a role in intercepting the polluted water or adjusting the flow rate of the polluted water.

T-shaped bumps 14 are provided on both sides of the first filter adsorption plate 4, and T-shaped grooves 15 adapted to the T-shaped bumps 14 are provided on both sides of the adsorption treatment box 2. The bolt buckle 13 facilitates fixing the hole cover plate 8 on the dispersion housing 6. At the same time, the uniform dispersion structure 3 can be opened to wipe and clean the inner side of the hole cover plate 8. The T-shaped bumps 14 and the T-shaped grooves 15 facilitate the fixing and clamping of the first filter adsorption plate 4, and at the same time facilitate the replacement and cleaning of the first filter adsorption plate 4.

[0026] Further, as Figure 1 shown in Figure 4 the additive dispenser 9 includes an adsorption reagent storage box 16, a second connecting pipe 17 penetrating and communicating between the adsorption reagent storage box 16 and the reagent adsorption box 1, a second electric control valve 18 provided on the second connecting pipe 17, and a sealed cover door 30 hinged to the opening end of the adsorption reagent storage box 16. The adsorption reagent storage box 16 facilitates storing the diluted adsorption reagent solution. The second connecting pipe 17 facilitates the diluted adsorption reagent solution in the adsorption reagent storage box 16 to flow into the reagent adsorption box 1. The second electric control valve 18 serves to intercept or regulate the flow rate of the diluted adsorption reagent solution.

[0027] Further, as Figure 1 shown in Figure 3 the second filter adsorption plate bracket 5 includes a connecting frame 19, a plurality of filter adsorption material placement plates 20 provided on the connecting frame 19, and a pull rod 21 provided on the connecting frame 19. The connecting frame 19 facilitates supporting and fixing the filter adsorption material placement plates 20. The filter adsorption material placement plates 20 facilitate placing various types of targeted adsorption substances. The pull rod 21 facilitates pulling out the second filter adsorption plate bracket 5 from the adsorption treatment box 2 and replacing the adsorption materials placed on the filter adsorption material placement plates 20.

[0028] Further, as Figure 4 shown in, a sealing door 22 is hinged to the front of the adsorption treatment box 2. There is only a pull ring 29 on the sealing door 22. The sealing door 22 is fixed to the adsorption treatment box 2 by bolts, which facilitates fixedly connecting the sealing door 22 to the adsorption treatment box 2. The sealing door 22 facilitates opening the adsorption treatment box 2 to replace the first filter adsorption plate 4 and the second filter adsorption plate bracket 5. At the same time, the inner side of the hole cover plate 8 can also be wiped and cleaned. The pull ring 29 facilitates opening the sealing door 22.

[0029] Further, as Figure 1 , Figure 2 and Figure 4As shown, the dispersion plate 7 is fixed to the edge of the lower surface of the feed port of the dispersion shell 6 by the connecting legs 23, and the adsorption reagent storage box 16 is fixedly connected to the upper surface of the reagent adsorption box 1 by the second connecting column 24 at the end corner. The connecting legs 23 facilitate the fixed connection of the dispersion plate 7 to the edge of the lower surface of the feed port of the dispersion shell 6, and the second connecting column 24 facilitates the fixed connection of the adsorption reagent storage box 16 to the upper surface of the reagent adsorption box 1.

[0030] Further, if Figure 1 ,and Figure 4 As shown, a water inlet pipe 25 is provided on the upper surface of the reagent adsorption box 1, a water outlet pipe 26 is provided on the lower surface of the adsorption treatment box 2, a third electrically-controlled valve 27 is provided on the water outlet pipe 26, and support legs 28 are provided at the end corners of the lower surface of the adsorption treatment box 2. The water inlet pipe 25 allows polluted water to be injected into the reagent adsorption box 1, and the water outlet pipe 26 allows the water after adsorption and filtration to be discharged from the device. The third electrically-controlled valve 27 serves to stop the filtered water or adjust the flow rate of the filtered water, and the support legs 28 facilitate supporting the device.

[0031] like Figures 1-4 As shown, the principle of the adsorption treatment equipment for heavy metal contaminated water provided in this embodiment is as follows: when using the device, the first electrically controlled valve 11, the second electrically controlled valve 18 and the third electrically controlled valve 27 should be closed first, and then the sealing door 22 should be opened to take out the second filter adsorption plate bracket 5, and a variety of targeted adsorption materials should be placed on the filter adsorption material placement plate 20 on the second filter adsorption plate bracket 5 in sequence, and then the second filter adsorption plate bracket 5 should be placed in the bottom of the inner cavity of the adsorption treatment box 2, and then the first filter adsorption plate 4 should be installed in the adsorption treatment box 2. After the installation is completed, the sealing door 22 can be closed and fixed to the adsorption treatment box 2 by bolts;

[0032] Subsequently, the diluted adsorption reagent solution is placed into the adsorption reagent storage box 16. Then, the heavy metal contaminated water flows into the reagent adsorption box 1 through the water inlet pipe 25. Next, the second electric control valve 18 is slowly opened, allowing the diluted adsorption reagent solution to flow into the reagent adsorption box 1 in a certain proportion. At this time, the diluted adsorption reagent solution reacts with the heavy metal contaminated water through adsorption. After the adsorption reaction is completed as much as possible, the first electric control valve 11 is opened, enabling the heavy metal contaminated water to flow into the uniform dispersion structure 3 in the adsorption treatment box 2. The heavy metal contaminated water flowing into the uniform dispersion structure 3 scatters onto the hole cover plate 8 under the action of the dispersion plate 7, and the first large particle metal pollutants in the heavy metal contaminated water are filtered. Then, it evenly flows onto the first filter adsorption plate 4. After the heavy metal contaminated water undergoes layer-by-layer adsorption and filtration by the first filter adsorption plate 4, it flows onto the second filter adsorption plate support 5 filled with the targeted adsorption material. At this time, the second filter adsorption plate support 5 filled with the targeted adsorption material conducts targeted adsorption and filtration on the heavy metal contaminated water. Then, the third electric control valve 27 can be opened to allow the adsorbed and filtered water to flow out of the device. Meanwhile, when the heavy metal contaminated water is being adsorbed and filtered, when all the heavy metal contaminated water in the reagent adsorption box 1 has flowed out, the first electric control valve 11 closes, and then the second electric control valve 18 is slowly opened, allowing the diluted adsorption reagent solution to flow into the reagent adsorption box 1 in a certain proportion. After the heavy metal contaminated water undergoes the adsorption reaction, one can wait for the first electric control valve 11 to open, enabling the metal contaminated water to enter the adsorption treatment box 2 for adsorption and filtration treatment.
