Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device based on a biofilm reactor of grape pomace. Background Technology

[0002] Wine production generates a significant amount of waste, including grape pomace. This waste is typically discarded or used for low-value purposes such as fertilizer or energy production, but it is rich in organic matter and nutrients, possessing potential value for wastewater treatment applications. Simultaneously, wine production facilities also generate wastewater that requires treatment to meet discharge or reuse requirements. Wastewater treatment in wine production typically employs a combined process of pretreatment, biological treatment, and advanced treatment. Supporting equipment includes mechanical bar screens, anaerobic towers, aeration tanks, and membrane treatment systems.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Traditional wastewater treatment devices often fail to adequately disperse wastewater upon entry, preventing sufficient contact between the wastewater and the biofilm during filtration. This results in poor filtration performance and increases the risk of liquid backflow and wastewater leakage, further reducing the device's wastewater treatment efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment device based on grape pomace biofilm reactor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biofilm reactor wastewater treatment device based on grape pomace, including a liquid discharge mechanism, the bottom end of which vertically penetrates the middle of the top of a cover plate, the bottom end of which covers the top opening of a reaction tank, a support column is provided in the middle of the bottom of the reaction tank, a water inlet mechanism is transversely penetrating one side of the support column, a distribution mechanism is inserted into the tail end of the water inlet mechanism, the interior of the reaction tank is filled with grape pomace medium, and a medium renewal mechanism is provided on one side of the bottom of the reaction tank.

[0007] More preferably, the liquid dispensing mechanism includes a liquid dispensing pipe, the bottom end of which vertically penetrates the middle of the top of the cover plate. A liquid dispensing valve is installed on the outer wall of the liquid dispensing pipe near the cover plate, and a check valve is installed on the outer wall of the liquid dispensing pipe away from the cover plate.

[0008] More preferably, the top center of the cover plate has an insertion hole, the inner wall of the insertion hole has a sealing layer, and the sealing layer is tightly attached to the outer wall of the liquid outlet pipe.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a wastewater treatment device based on grape pomace biofilm reactor, including a liquid discharge mechanism 1, the bottom end of which vertically penetrates the middle of the top of a cover plate 2, the bottom end of the cover plate 2 covering the top opening of a reaction tank 3, a support column 4 provided in the middle of the bottom of the reaction tank 3, a water inlet mechanism 5 horizontally penetrating one side of the support column 4, a distribution mechanism 6 inserted at the tail end of the water inlet mechanism 5, grape pomace medium 7 filling the interior of the reaction tank 3, and a medium renewal mechanism 8 provided on one side of the bottom of the reaction tank 3.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, the liquid dispensing mechanism 1 includes a liquid dispensing pipe 101. The bottom end of the liquid dispensing pipe 101 vertically penetrates the middle of the top of the cover plate 2. A liquid dispensing valve 102 is installed on the outer wall of the liquid dispensing pipe 101 near the cover plate 2, and a check valve 103 is installed on the outer wall of the liquid dispensing pipe 101 away from the cover plate 2.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, an insertion hole 201 is provided in the middle of the top of the cover plate 2, and a sealing layer 202 is provided on the inner wall of the insertion hole 201. The sealing layer 202 is tightly attached to the outer wall of the liquid outlet pipe 101.

[0024] In this embodiment, as Figure 4 As shown, the water inlet mechanism 5 includes an inlet valve 501, which is installed on the outer wall of the inlet pipe 502. One end of the inlet pipe 502 extends laterally through one side of the support column 4, and a distribution mechanism 6 is inserted into one side port of the inlet pipe 502.

[0025] In this embodiment, as Figure 4 As shown, the distribution mechanism 6 includes a guide pipe 601, one end of which is connected to an inlet pipe 502. The top end of the guide pipe 601 is provided with several branch pipes 602, and the top of the branch pipes 602 is provided with several water distribution holes 603. The branch pipes 602 are located directly below the grape pomace medium 7.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, a feeding hopper 203 is vertically inserted through one side of the top of the cover plate 2.

[0027] In this embodiment, as Figure 3 As shown, the medium renewal mechanism 8 includes a slag discharge pipe 801. The top end of the slag discharge pipe 801 is inserted into the bottom side of the reaction tank 3. A slag discharge valve 802 is installed on the outer wall of the slag discharge pipe 801. The slag discharge pipe 801 is inclined.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the biofilm reactor wastewater treatment device based on grape pomace operates as follows:

[0029] First, the operator can connect the external sewage pipe to the inlet flange of the inlet pipe 502, and then open the inlet valve 501 to let the sewage to be treated flow into the inside of the inlet pipe 502. During this process, the sewage will flow along the inlet pipe 502 into the guide pipe 601 inserted at the other end. At this time, under external power, the sewage will be pushed upward along the guide pipe 601 to several annularly distributed branch pipes 602. During this process, the sewage will be evenly distributed in the grape pomace medium 7 when it flows through the water distribution hole 603 at the top of the branch pipe 602, thereby ensuring that the sewage can fully contact the grape pomace medium 7.

[0030] After the wastewater is introduced, the grape pomace medium 7 filled inside the reaction tank 3 serves as a biofilm carrier. During the process of full contact between the wastewater and the grape pomace medium 7, the pollutants in the wastewater are degraded and transformed through the metabolic action of the microorganisms on the surface of the biofilm formed on the surface of the grape pomace medium 7, thereby achieving the purification of the wastewater.

[0031] After the wastewater has been purified, it will be temporarily stored inside the reaction tank 3. At this time, the operator can open the outlet valve 102 to allow the treated wastewater to flow out through the outlet pipe 101. During this process, since a check valve 103 is installed on the outer wall of the outlet pipe 101 away from the cover plate 2, the operator can control the check valve 103 to prevent liquid backflow and ensure the one-way flow of the liquid.

[0032] After the grape pomace medium 7 has been used for a certain period of time, the operator can open the slag discharge valve 802 in the medium renewal mechanism 8, so that the grape pomace medium 7 inside the reaction tank 3 is discharged along the slag discharge pipe 801 under the action of gravity. After discharge, new grape pomace medium 7 can be added to the reaction tank 3 through the feeding hopper 203 that runs vertically through one side of the top of the cover plate 2.
