Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, specifically a biochemical treatment device for brewing yellow water. Background Technology
[0002] Yellow water is a byproduct of winemaking. During the winemaking process, after the mash is placed in the fermentation pit, the starch is converted from sugar into alcohol, and carbon dioxide is produced at the same time. The mass of each unit of mash is relatively reduced, and the water of crystallization is released. Tannins, pigments, soluble starch, yeast autolysates, reducing sugars, etc. in the raw materials dissolve in the water and sink to the bottom of the pit to form yellow water.
[0003] Yellow water, an important byproduct of the brewing process, can only be treated as wastewater, with a small portion capable of recycling and reuse. However, due to its rich content of organic matter, microorganisms, and nutrients, direct discharge would cause significant environmental pollution, necessitating harmless treatment before release. Originating during the fermentation of the mash, yellow water has a complex composition, containing large amounts of sugars, alcohols, organic acids, amino acids, esters, vitamins, and minerals, as well as abundant microbial resources such as yeast and lactic acid bacteria. However, this high concentration of organic matter and complex composition presents challenges for its treatment. Traditional wastewater treatment methods often suffer from poor treatment efficiency and low resource recovery rates. For example, simple physical methods such as sedimentation and filtration are insufficient to effectively remove dissolved organic matter and microorganisms from yellow water, while chemical treatment methods may introduce secondary pollution and are costly.
[0004] Therefore, how to design a device that can better achieve the harmless treatment of yellow water has become a problem that needs to be considered and solved by those skilled in the art. Utility Model Content
[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a biochemical treatment device for brewing yellow water that can better achieve the harmless treatment of brewing yellow water, so that it has high yellow water treatment efficiency and good treatment effect.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0007] A biochemical treatment device for yellow brewing wastewater includes a reaction vessel with an overall closed design. One end of the reaction vessel has an inlet pipe, and the other end has an outlet pipe. A dynamic membrane assembly is also installed inside the reaction vessel. The dynamic membrane assembly is a vertically cylindrical structure, including an inner cylindrical frame and a membrane mesh attached to the outside of the frame. The inlet end of the outlet pipe is connected to the inside of the frame. The frame is made of metal, and the membrane mesh is made of water-permeable carbon cloth. An anode component made of conductive material is also arranged parallel to each other on one side of the dynamic membrane assembly. A current control module is installed outside the reaction vessel. The current control module has an anode output terminal and a cathode output terminal. The cathode output terminal is connected to the frame via a wire, and the anode output terminal is connected to the anode component via a wire.
[0008] In this way, when the device is in use, the brewing wastewater enters the reaction vessel through the inlet pipe. The current control module can control the output of a small current (the current control on-site electric field can inhibit the fermenting microorganisms contained in the wastewater, but cannot kill the active microorganisms required for wastewater treatment), so that the dynamic membrane module forms a cathode and a micro electric field is formed between it and the anode. Under the action of the electric field, the active fermenting organisms such as yeast and lactic acid bacteria originally contained in the wastewater are inhibited. Then, the wastewater undergoes biochemical filtration treatment in the dynamic membrane bioreactor formed after the membrane is attached to the dynamic membrane module, and is then discharged through the outlet pipe. Dynamic membrane bioreactors, also known as DMBRs, are an existing wastewater treatment process. They utilize a mesh material with a specific pore size (e.g., micrometers or nanometers) as a filter substrate, which is fixed to a filter support material inside the reactor, creating two chambers. Sludge is cultivated in one chamber, allowing microorganisms to attach, grow, and reproduce on one side, forming a biofilm once a certain density is reached. Wastewater is then introduced into this chamber, creating a head difference with the other chamber. The wastewater undergoes filtration and biological action through the biofilm, achieving a certain treatment effect. The cleaner water then flows into the other chamber for further treatment. In this application, carbon cloth is used as the biofilm attachment mesh, facilitating both microbial attachment and biofilm formation while also enabling the conduction of microcurrents. This creates an electric field within the reaction vessel, inhibiting active fermentation.
[0009] Furthermore, the water inlet pipe is connected to the lower end of the reaction vessel, and the water outlet pipe is connected from the upper end of the reaction vessel.
[0010] This is because the activated sludge components in the reaction vessel are mostly located at the bottom of the vessel, so it is more beneficial to improve the treatment effect by having water enter from the bottom and exit from the top.
[0011] Furthermore, a water inlet pump is installed on the water inlet pipe and connected to a water inlet tank.
[0012] This makes it easier for yellow water to enter and maintain sufficient inlet pressure.
[0013] Furthermore, a water pump and a pressure gauge are installed on the water outlet pipe.
[0014] This ensures sufficient outlet water pressure and allows for the detection of transmembrane pressure differential during the deposition process of the cathode dynamic membrane module.
[0015] Furthermore, the skeleton is made of stainless steel mesh.
[0016] Using stainless steel mesh as the bottom layer, which serves as both a current collector and filter support material, provides robustness to the filter module and ensures sufficient conductivity.
[0017] Furthermore, the anode component is composed of carbon felt, ensuring sufficient conductivity and a good electric field generation effect.
[0018] Furthermore, the distance between the dynamic membrane module and the anode is set to 30 mm.
[0019] This ensures a sufficient electric field effect.
[0020] Furthermore, the anode is integrally formed in an arc or ring shape coaxial with the framework. This allows for better control over the generation of a uniform electric field.
[0021] Furthermore, a magnetic stirring device is also provided, which includes a magnetic stirrer base located below the reaction vessel and a stir bar located at the bottom of the inner cavity of the reaction vessel.
[0022] In this way, by using a magnetic stirrer, the internal stirring of the reaction vessel can be controlled without physical contact, thus better ensuring the treatment effect of yellow water.
[0023] Furthermore, a nitrogen cylinder is also provided, which is connected to the top of the reaction vessel via a pipe with a switch.
[0024] This maintains the anaerobic environment within the reactor, ensuring the normal growth and metabolism of anaerobic microorganisms.
[0025] Furthermore, an exhaust pipe is connected to the upper end of the reaction vessel, and the exhaust pipe is connected to a gas collection container.
[0026] In this way, biogas produced during the anaerobic biological treatment of brewing wastewater can be collected and utilized as a resource.
[0027] Furthermore, a dosing tank is also provided, which is connected to the upper end of the reaction vessel via a dosing pipe, and a metering pump is installed on the dosing pipe.
[0028] This makes it convenient to add chemicals into the reaction vessel, thus aiding in the harmless treatment of the yellow water.
[0029] In summary, this utility model, designed for the harmless treatment of yellow brewing wastewater, employs a dual treatment method combining ionization and dynamic membrane technology, resulting in high treatment efficiency and good treatment effect. Attached Figure Description

[0046] The device also includes a magnetic stirring device, which includes a magnetic stirrer base 14 located below the reaction vessel and a stir bar 13 located at the bottom of the inner cavity of the reaction vessel.
[0047] In this way, by using a magnetic stirrer, the internal stirring of the reaction vessel can be controlled without physical contact, thus better ensuring the treatment effect of yellow water.
[0048] It also includes a nitrogen cylinder 15, which is connected to the upper part of the reaction vessel via a pipe with a switch.
[0049] This maintains the anaerobic environment within the reactor, ensuring the normal growth and metabolism of anaerobic microorganisms.
[0050] The upper end of the reaction vessel is also connected to an exhaust pipe, which is connected to a gas collection container 6.
[0051] In this way, biogas produced during the anaerobic biological treatment of brewing wastewater can be collected, realizing waste utilization. In practice, the gas collection container 6 is a flexible bag-shaped container for convenient gas collection.

The effluent COD was stable at 102 ± 10 mg / L, and the COD removal rate reached 93%.
