Description

Technical Field

[0001] This utility model belongs to the field of wastewater ozone oxidation equipment, specifically a wastewater containing iron organic complexes ozone oxidation separation and treatment device. Background Technology

[0002] Ozone oxidation devices are equipment specifically designed for wastewater treatment. They utilize the strong oxidizing properties of ozone to decompose and remove organic matter, heavy metals, and other harmful substances from wastewater. These devices typically combine multiple treatment technologies to achieve efficient wastewater purification and are widely used in fields such as water disinfection, removal of organic pollutants, water decolorization, removal of metal ions, and odor removal.

[0003] Iron-containing organic complex wastewater is a special type of industrial wastewater containing complexes formed by iron ions and organic ligands. This type of wastewater usually originates from industrial production processes such as electroplating, electroless plating, metal surface treatment, pharmaceuticals, petrochemicals, and dyes. Due to the combination of iron ions and organic ligands, this type of wastewater is difficult to treat and requires specific technologies and methods to effectively remove pollutants. Ozone oxidation devices are commonly used, which can effectively decompose organic matter, including complexes formed by metal ions.

[0004] However, iron-containing organic complex wastewater treated by ozone catalytic oxidation will still have residual particulate matter in the water. This is mainly because during the ozone catalytic oxidation process, organic matter is decomposed into small molecules, which exist in the water in the form of particulate matter. These particulate matter can affect subsequent treatment equipment and thus reduce treatment efficiency.

[0005] In summary, this invention provides an ozone oxidation separation and treatment device for iron-containing organic complex wastewater to solve the above-mentioned problems. Utility Model Content

The ozone catalytic oxidation component includes an oxidation reaction tower and an ozone generator. The ozone generator generates ozone, and the oxidation reaction tower provides a catalytic reaction. A separation component is installed on one side of the ozone catalytic oxidation component. The separation component includes a tank, a conical hopper, a filter plate, a drain pipe, a drain valve, an overflow pipe, and an inlet pipe.

Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model. Example 1

[0023] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides an ozone oxidation separation and treatment device for iron-containing organic complex wastewater, including an ozone catalytic oxidation component 1. The ozone catalytic oxidation component 1 includes an oxidation reaction tower 11 and an ozone generator 12. The ozone generator 12 is used to generate ozone, and the oxidation reaction tower 11 is used to provide a catalytic reaction. A separation component 2 is installed on one side of the ozone catalytic oxidation component 1. The separation component 2 includes a tank 201, a conical hopper 202, a filter plate 203, a drain pipe 204, a drain valve 205, an overflow pipe 206, and an inlet pipe 207. The conical hopper 202 is fixed to the bottom of the tank 201. The filter plate 203 is installed at the upper end of the inner cavity of the tank 201. One end of the liquid inlet pipe 207 is connected to the inner cavity of the tank 201, and the other end of the liquid inlet pipe 207 is connected to the oxidation reaction tower 11. The overflow pipe 206 is located at the upper end of the tank 201 and is connected to the inner cavity of the tank 201. The sewage pipe 204 is installed at the bottom of the conical bucket 202 and is connected to the inner cavity of the conical bucket 202. The sewage valve 205 is installed on the surface of the sewage pipe 204. The separation component 2 is used to separate particulate matter in the water. The surface of the separation component 2 is equipped with a stirring component 3, which is used to improve the separation efficiency.

[0024] like Figure 1-4As shown, firstly, the ozone generator 12 in the ozone catalytic oxidation component 1 generates ozone. The ozone enters the oxidation reaction tower 11 and undergoes a catalytic oxidation reaction with the organic matter in the wastewater. During this process, the organic matter is decomposed into small molecules, some of which exist in the form of particulate matter. Then, the treated wastewater enters the tank 201 of the separation component 2 through the outlet pipe 116. A filter plate 203 is installed at the upper end of the inner cavity of the tank 201. The filter plate 203 can intercept the particulate matter in the wastewater and prevent it from entering the subsequent treatment equipment with the water flow. The separation efficiency can be improved by the stirring component 3. When the particulate matter is intercepted by the filter plate 203, it will be deposited on the cone. In the conical hopper 202, the design facilitates the collection and discharge of particulate matter. When sewage needs to be discharged, simply open the drain valve 205, and the particulate matter will be discharged through the drain pipe 204. The filtered clean water is discharged through the overflow pipe 206 and enters the subsequent treatment process. With the joint cooperation of the ozone catalytic oxidation component 1, the separation component 2, and the stirring component 3, not only can the ozone catalytic oxidation reaction be effectively carried out, but the particulate matter in the wastewater can also be efficiently separated and discharged. This effectively solves the problem of residual particulate matter in the wastewater after ozone catalytic oxidation treatment, improves the overall treatment efficiency, and protects the normal operation of the subsequent treatment equipment. Example 2

[0025] Reference Figure 2 and 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0026] In this embodiment, the stirring assembly 3 includes a motor 301, a reducer 302, a transmission rod 303, and a stirrer 304. The motor 301 and the reducer 302 are both fixed to the top of the tank 201, and the transmission rod 303 and the stirrer 304 are both installed in the inner cavity of the tank 201.

[0027] One end of the transmission rod 303 passes through the filter plate 203 and is fixedly connected to the agitator 304. The other end of the transmission rod 303 passes through the outside of the tank 201 and is connected to the output shaft of the reducer 302. The output shaft of the motor 301 is connected to the input shaft of the reducer 302.

[0028] like Figure 2 and 4 As shown, the stirring assembly 3 consists of a motor 301, a reducer 302, a transmission rod 303, and a stirrer 304. After the motor 301 starts, the speed is reduced by the reducer 302, and then the power is transmitted to the stirrer 304 through the transmission rod 303. The stirrer 304 stirs inside the tank 201. This stirring process can make the particulate matter in the wastewater more evenly distributed, preventing it from settling at the bottom of the tank 201 or adhering to the filter plate 203, thereby improving the separation efficiency. Example 3

[0029] Reference Figure 1 and 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0030] In this embodiment, the ozone generator 12 is located on one side of the oxidation reaction tower 11. The oxidation reaction tower 11 includes a tower body 111, a wastewater distributor 112, a gas distributor 113, a catalyst bed 114, a packing bed 115, a liquid outlet pipe 116, a water inlet pipe 117, an exhaust pipe 118, and an air inlet pipe 119.

[0031] Wastewater distributor 112, gas distributor 113, catalyst bed 114 and packing bed 115 are all fixed in the inner cavity of tower body 111 and are distributed sequentially from bottom to top. Wastewater distributor 112 is used to distribute wastewater and gas distributor 113 is used to distribute ozone gas.

[0032] One end of the air inlet pipe 119 is connected to the output end of the ozone generator 12, and the other end of the air inlet pipe 119 is connected to the gas distributor 113. One end of the water inlet pipe 117 is connected to the wastewater distributor 112. One end of the liquid outlet pipe 116 is connected to the liquid inlet pipe 207, and the other end of the liquid outlet pipe 116 is connected to the liquid outlet end of the tower body 111. The exhaust pipe 118 is connected to the gas outlet end of the tower body 111.

[0033] The packed bed 115 is filled with ceramic particles, and the catalytic bed 114 can be made of activated carbon.

[0034] like Figure 1 and 3 As shown, ozone generator 12 produces ozone gas, which enters the gas distributor 113 of oxidation reaction tower 11 through inlet pipe 119 and is evenly distributed in tower body 111. Wastewater enters the wastewater distributor 112 through inlet pipe 117 and is evenly distributed in tower body 111, making full contact with ozone gas. Under the action of catalytic bed 114 and packing bed 115, ozone undergoes catalytic oxidation reaction with organic matter in wastewater, decomposing organic matter into small molecules. The treated wastewater is discharged through outlet pipe 116, and the exhaust gas is transported to the waste gas purification device for treatment through exhaust pipe 118. The ozone catalytic oxidation component 1 can also be equipped with a backwashing device, which can be used to clean catalytic bed 114 and packing bed 115.

[0035] During operation, ozone generator 12 produces ozone gas, which enters the gas distributor 113 of oxidation reaction tower 11 through inlet pipe 119 and is evenly distributed within tower body 111. Wastewater enters the wastewater distributor 112 through inlet pipe 117 and is also evenly distributed within tower body 111, ensuring full contact with the ozone gas. Under the action of catalytic bed 114 and packed bed 115, ozone undergoes a catalytic oxidation reaction with organic matter in the wastewater, decomposing the organic matter into smaller molecules. The treated wastewater enters tank 201 through outlet pipe 116 and inlet pipe 207. The exhaust gas is transported to the waste gas purification device for treatment through exhaust pipe 118. The treated wastewater enters tank 201 through inlet pipe 207, where particulate matter is filtered out by filter plate 203. The clean water is discharged through overflow pipe 206, and the particulate matter settles in the filter. In the conical hopper 202, when sewage needs to be discharged, the drain valve 205 is opened, and the particulate matter is discharged through the drain pipe 204. After the motor 301 starts, the speed is reduced by the reducer 302, and then the power is transmitted to the agitator 304 through the transmission rod 303. The agitator 304 stirs in the tank 201. This stirring process can make the particulate matter in the wastewater more evenly distributed, avoiding its deposition at the bottom of the tank 201 or its adhesion to the filter plate 203, thereby improving the separation efficiency. With the joint cooperation of the ozone catalytic oxidation component 1, the separation component 2 and the stirring component 3, not only can the ozone catalytic oxidation reaction be effectively carried out, but the particulate matter in the wastewater can also be efficiently separated and discharged. This effectively solves the problem of residual particulate matter in the wastewater after ozone catalytic oxidation treatment, improves the overall treatment efficiency, and protects the normal operation of subsequent treatment equipment.

Therefore, the scope of protection of this invention shall be determined by the claims.
