Technical Field

[0002] Modern industrial production processes, such as those in the petroleum, chemical, and metallurgical industries, generate large quantities of wastewater containing oily organic pollutants. These pollutants not only cause severe environmental pollution but also pose a threat to human health. Therefore, effectively removing these pollutants from wastewater has become a research hotspot in the environmental protection field.

[0003] Currently, the main methods for treating wastewater containing oily organic pollutants include gravity separation, flotation, and adsorption. Although gravity separation and flotation have certain treatment effects, they are mainly targeted at high-concentration oily organic pollutants, and the equipment occupies a large area and has high operating costs. Adsorption is a treatment method that has developed rapidly in recent years. It utilizes the affinity of adsorbent materials for oily organic pollutants to remove them through physical or chemical adsorption. However, the devices suitable for adsorption in the existing technology usually have complex structures, cumbersome regeneration of the adsorption layer, and inconvenient operation, resulting in high treatment costs and low treatment efficiency.

[0004] Therefore, a new type of treatment device for wastewater containing oily organic pollutants is needed to overcome the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a treatment device for wastewater containing oily organic pollutants to solve the problems existing in the above-mentioned prior art. The wastewater containing oily organic pollutants is treated by an adsorption layer with lipophilic and hydrophobic properties to separate oil and water. When the adsorption layer is saturated, the adsorption layer is suctioned to remove oil stains, so as to achieve regeneration of adsorption capacity and allow the adsorption layer to be recycled. In the present invention, the adsorption layer is installed on a foldable support frame, and the support frame is installed on a suction pipe. When adsorbing oil stains in the wastewater, the support frame is opened to allow the adsorption layer to start working. When the adsorption layer is saturated and needs to be regenerated, the support frame is folded to allow the adsorption layer to stick to the suction pipe, and the oil stains are separated from the adsorption layer by suction. The structure of the entire treatment device for wastewater containing oily organic pollutants is simple, and wastewater treatment and adsorption capacity regeneration can be completed without repeatedly disassembling and assembling the adsorption layer.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] like Figure 1 and Figure 2 As shown, the utility model provides a treatment device for wastewater containing oily organic pollutants, comprising an adsorption layer 2 for absorbing oily organic pollutants, and a suction pipe 3 for absorbing oily organic pollutants in the adsorption layer 2, a support frame 1 for carrying the adsorption layer 2 is provided on the suction pipe 3, the adsorption layer 2 is laid on the support frame 1, the suction pipe 3 is a hollow structure, a through hole 10 is provided on the surface of the suction pipe 3, the top of the suction pipe 3 is sealed, and a suction port 7 for connecting to a suction device is provided at the bottom of the suction pipe 3, the support frame 1 is a folding structure, and when the support frame 1 is folded, the adsorption layer 2 is attached to the suction pipe 3 and covers the through hole on the surface of the suction pipe. The adsorption layer 2 has the characteristics of lipophilicity and hydrophobicity. When wastewater containing oily organic pollutants passes through the adsorption layer 2, the oily organic pollutants are absorbed by the adsorption layer 2, and the treated water will flow away and be recovered. When the adsorption layer 2 reaches a saturated state, the oily organic pollutants contained in the adsorption layer 2 can be sucked out and treated by suction. The supporting frame 1 is arranged around the suction pipe 3 and has a folding structure. The adsorption layer 2 can complete wastewater treatment and adsorption capacity regeneration without disassembly. It is easy to operate, simple in structure, and improves treatment efficiency.

[0031] like Figure 1 As shown, in the axial direction of the suction tube 3, the through holes 10 form at least two circles of through hole groups, and the through holes 10 in two adjacent circles of through hole groups are relatively arranged or staggered in the axial direction of the suction tube 3. The distribution area of ​​the through holes 10 is consistent with the area where the adsorption layer 2 is attached to the suction tube 3, which can ensure that the through holes 10 effectively correspond to the adsorption layer 2, and the adsorption points are uniform, which has a better effect in sucking out oily organic pollutants.

[0032] like Figure 1 As shown, the present invention further includes a base plate and a housing 4. The bottom of the suction pipe 3 is disposed on the base plate, which is provided with a discharge hole 8 for recovering filtered water. The housing 4 is sleeved on the base plate, and the housing 4 and the base plate together form a temporary storage space for the filtered water. Water falling from the adsorption layer 2 enters the temporary storage space, preventing the treated water from flowing freely and facilitating collection. In a preferred embodiment, the suction pipe 3, the support frame 1, and the adsorption layer 2 are all disposed within the housing 4.

[0033] like Figure 1 As shown, the adsorption layer 2 is provided with water-permeable holes 9 for allowing water to pass through, so that water can quickly leave the current adsorption layer 2, that is, it can be quickly recovered without hindering treatment. Multiple circles of water-permeable holes 9 can be arranged radially on the adsorption layer 2, and the multiple circles of water-permeable holes 9 are distributed at equal intervals.

[0034] like Figure 1 and Figure 2 As shown, the suction tube 3 is a round tube, and the supporting frame 1 is an umbrella-shaped structure. When the supporting frame 1 is opened, the adsorption layer 2 is umbrella-shaped, and when the supporting frame 1 is folded, the adsorption layer 2 is stacked. The overall umbrella-shaped structure is relatively simple and easy to control. The stacking structure can expand the area of ​​the adsorption layer 2 when it is opened without affecting the subsequent suction effect.

[0035] like Figure 1 As shown, a water inlet pipe for transmitting wastewater containing oily organic pollutants is arranged above the suction pipe 3. The water inlet pipe is a hollow structure. A water inlet 5 is arranged on the top of the water inlet pipe. The side wall of the water inlet pipe is provided with dispersion holes 6 for dispersing the wastewater containing oily organic pollutants to the adsorption layer 2. The water inlet 5 is located in the center of the adsorption layer 2. The dispersed wastewater can completely cover the adsorption layer 2 and effectively utilize the adsorption layer 2. The water inlet pipe can be a circular tube. The dispersion holes 6 are arranged around the bottom of the circular tube, and the dispersion holes 6 are evenly distributed.

[0036] The material of the adsorption layer 2 is polypropylene melt-blown fiber. The utility model includes at least two adsorption layers 2. The adsorption layers 2 are arranged along the axial direction of the suction tube 3. The adsorption layers 2 are distributed at equal intervals. Figure 1 As shown, in a preferred embodiment, there are three adsorption layers 2 .

[0037] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
