DETAILED DESCRIPTION

[0018] The utility model is described in detail below with reference to the accompanying drawings:

[0019] like Figure 1 and 2As shown, a resin adsorption device comprises an outer tank 1, wherein an inner tank 2 coaxially arranged with the outer tank 1 is arranged inside the outer tank 1, the inner tank 2 passes through the upper and lower ends of the outer tank 1, and a resin adsorption area 3 is formed in the middle of the inner tank 2. Resin can be added to the resin adsorption area 3 for adsorbing sewage, and a first filter layer 4 is arranged at the upper part of the resin adsorption area 3, and a second filter layer 5 is arranged at the lower part. The first filter layer 4 and the second filter layer 5 can be made of activated carbon or a filter mesh plate, etc. Specifically, a support mesh plate 6 is arranged on the upper side of the resin adsorption area 3, and the first filter layer 4 is located on the support mesh plate 6. In addition, a support platform 1 corresponding to the support mesh plate 6 is arranged on the inner tube 2 8. The support mesh plate 6 is located on the support platform 18. The support mesh plate 5 is arranged to facilitate the removal of the support mesh plate 6, and then the resin in the resin adsorption area 3 can be replaced. The second filter layer 5 can be directly placed on the bottom end of the inner tube 2. The top of the inner tank 2 forms a liquid inlet 7, and the bottom is connected with a drain pipe 8. The sewage to be treated can be added into the inner tank 2 through the liquid inlet 7. After adsorption and filtration, the water can be discharged through the drain pipe 8. The drain pipe 8 is provided with a drain valve 9. The upper part of the inner tank 2 forms a spherical liquid storage section 10. The liquid storage section 10 is located above the first filter layer 4. The liquid storage section 10 can increase the capacity of the sewage to be filtered in the inner tank 2.

[0020] A tubular aerator 11 is provided in the inner tank 2. The tubular aerator 11 is located at the bottom of the resin adsorption area 3. The tubular aerator 11 is connected to an air supply pipe 12. An air supply valve 13 is provided on the air supply pipe 12. The air supply valve 13 can be used to adjust the air supply volume. The air supply pipe 12 passes through the side walls of the inner tank 2 and the outer tank 1. The air supply pipe 12 is connected to an air source. Air can be input into the resin adsorption area 3 through the tubular aerator 11, so that the resin in the resin adsorption area 3 is in a suspended state after mixing with the sewage, thereby increasing the contact area with the sewage and improving the adsorption effect.

[0021] A heating chamber 14 is formed between the outer tank 1 and the inner tank 2. The upper portion of the heating chamber 14 is connected to a water inlet pipe 15, and the lower portion is connected to a water outlet pipe 16. The water outlet pipe 16 is provided with a water outlet valve 17. Hot water can be input into the heating chamber 14 through the water inlet pipe 15 to heat the inner tank 2.

[0022] The usage of the utility model is as follows:

[0023] When it is necessary to treat the wastewater, firstly, the first filter layer 4 and the supporting mesh plate 5 in the inner tank 2 are taken out, and then resin is added to the resin adsorption area 3 of the inner tank 2 through the liquid inlet 7 at the top of the inner tank 2, and then the supporting mesh plate 6 and the first filter layer 4 are placed in the inner tank 2 to treat the wastewater. Firstly, sewage is added to the inner tank 2 through the liquid inlet 7, and the sewage is gathered in the liquid storage section 10. Then, the sewage is filtered for the first time through the first filter layer 4, and the filtered sewage gradually enters the resin adsorption area 3. The organic matter and other pollutants in the sewage are removed by the resin. During adsorption, the air supply valve 13 can be opened, and air is supplied to the tubular aerator 11 through the air supply pipe 12, and air is supplied to the resin adsorption area 3 through the aerator 11, so that the resin and sewage are mixed in a suspended state, and the contact area between the resin and the sewage is increased to improve the adsorption effect. After a period of adsorption, the drain valve 9 is opened, and the sewage after adsorption is filtered through the second filter layer 5 and finally discharged from the drain pipe 8.

[0024] When the resin has been used for a period of time and the adsorption reaches a saturated state, the resin can be desorbed. Specifically, the first filter layer 4, the support mesh plate 6 and the second filter layer 5 are taken out and cleaned for subsequent filtration. The drain valve 9 is closed, and the resin is placed in the resin adsorption area 3. Then, a desorption solvent is added to the resin adsorption area 3, and hot water is added to the heating chamber 14 through the water inlet pipe 15 to increase the temperature in the resin adsorption area 3 so that the resin adsorption area 3 is at a suitable temperature to improve the desorption efficiency of the resin. After desorption is completed, the drain valve 9 is opened to drain the desorption solvent from the drain pipe 8. During filtration and adsorption, the temperature of the resin adsorption area 3 can be adjusted according to the situation to achieve the best adsorption effect.

[0025] The device has good sewage treatment effect and can effectively remove most impurities and organic pollutants in sewage.
