Description

Technical Field

[0001] This utility model relates to the field of liquor production technology, and in particular to a wastewater treatment device for liquor production. Background Technology

[0002] As a traditional Chinese beverage, baijiu (Chinese liquor) generates a large amount of wastewater during its production. This wastewater contains not only high concentrations of organic matter, suspended solids, and colloidal substances, but also residual alcohol, sugars, and proteins. If discharged directly without effective treatment, it will severely pollute the soil, water bodies, and other ecological environments, affecting the survival of surrounding flora and fauna, disrupting the ecological balance, and violating national sustainable development and environmental protection policies. Therefore, the efficient treatment of baijiu production wastewater is crucial for environmental protection and the sustainable development of the industry.

[0003] Currently, although there are applications of wastewater treatment technology for liquor production, there are still many problems. Traditional sedimentation treatment methods can remove some suspended solids, but sediment at the bottom of the pool is prone to hardening and is difficult to clean thoroughly, resulting in reduced sedimentation efficiency. In addition, there is a lack of an effective collection mechanism for surface scum, which affects subsequent treatment processes.

[0004] In the advanced treatment stage, a single physical filtration or biochemical treatment method is difficult to meet the removal requirements of multiple pollutants simultaneously. For example, physical filtration cannot effectively decompose organic matter, while biochemical treatment has limited effect on removing suspended solids, making it difficult for the treated water quality to meet discharge standards. In addition, existing treatment devices mostly adopt decentralized treatment units, which occupy a large area, have loose connections between treatment stages, require a large amount of power equipment to drive the wastewater flow, have high energy consumption and high operating costs, and have complex operation procedures, which is not conducive to the long-term application and promotion of liquor production enterprises.

[0005] Therefore, it is urgent to develop a wastewater treatment device for liquor production that integrates high-efficiency sedimentation, multi-stage treatment, and energy saving. The wastewater treatment device provided by this invention aims to solve the above-mentioned problems in the existing technology and provide a more environmentally friendly, efficient, and economical wastewater treatment solution for the liquor production industry. Utility Model Content

[0006] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a wastewater treatment device for liquor production that can solve the above-mentioned problem.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device for liquor production, comprising a sedimentation tank, a wastewater inlet fixedly connected to the side wall of the sedimentation tank, a motor fixedly connected to the sedimentation tank, a rotating shaft rotatably connected inside the sedimentation tank, and the output end of the motor fixedly connected to the rotating shaft.

[0008] A slag collection ring is fixedly connected to the top of the sedimentation tank. The slag collection ring has a slag collection port inside, and a conveying pipe is fixedly connected to the slag collection ring.

[0009] A water pump is placed on the right side of the sedimentation tank, and a support is placed on the right side of the water pump. Two reaction tanks are fixedly connected to the support, and an activated carbon filter is fixedly connected inside the upper reaction tank.

[0010] A biochemical treatment module is fixedly connected to the side wall of the upper reaction tank;

[0011] An asbestos mesh filter is fixedly connected inside the lower reaction tank;

[0012] A water pipe is fixedly connected to the sedimentation tank, and the other end of the water pipe is connected to the reaction tank at the top of the support. A water pump is installed on the water pipe.

[0013] Preferably, a brush is rotatably connected to the bottom of the rotating shaft.

[0014] Preferably, a scraper is fixedly connected to the upper end of the rotating shaft, and the scraper is at a ° angle to the water surface in order to clean up the floating scum.

[0015] Preferably, the slag collection port is connected to the conveying pipeline.

[0016] Preferably, a collection box is placed below the support.

[0017] Preferably, the slag collecting ring is annular and has grooves.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) In this wastewater treatment device for liquor production, the wastewater after sedimentation is pumped through a water pipe to the upper reaction tank on the support under the action of a water pump. After entering the upper reaction tank, the wastewater first passes through the activated carbon filter screen that is fixedly connected inside. The activated carbon filter screen uses the adsorption characteristics of activated carbon to adsorb organic pollutants, pigments, odors and other impurities in the wastewater, further purifying the water quality. At the same time, the biochemical treatment module that is fixedly connected to the side wall of the upper reaction tank starts to work. The microbial community in the biochemical treatment module decomposes the organic matter in the wastewater through biodegradation, converting it into harmless carbon dioxide and water. The wastewater after being treated by the activated carbon filter screen and the biochemical treatment module flows into the lower reaction tank. The asbestos mesh filter screen that is fixedly connected inside the lower reaction tank can filter and intercept the residual small particles and suspended solids in the wastewater, ensuring that the wastewater reaches a high purification standard. Finally, the water that has been purified through multiple layers of treatment flows from the lower reaction tank into the collection box placed below the support, completing the entire process of treating wastewater from liquor production. The treated water can be reasonably utilized or discharged according to actual needs.

[0020] (2) The wastewater treatment device for liquor production has a brush fixed at the bottom of the rotating shaft to wash the bottom of the sedimentation tank to prevent the sediment from accumulating and hardening at the bottom of the tank. At the same time, the scraper at the top of the rotating shaft rotates synchronously with the rotating shaft. The scraper is at an angle of ° to the water surface. This special angle design can effectively scrape the floating scum on the water surface into the scum collection ring at the top of the sedimentation tank. The scum collection ring is annular and has a groove. After the scum is scraped in, it enters the conveying pipe through the scum collection port opened inside the scum collection ring. The conveying pipe transports the scum to the subsequent treatment stage. Attached Figure Description

[0031] Please see Figure 1-4 This utility model provides a technical solution: a wastewater treatment device for liquor production, including a sedimentation tank 2, a wastewater inlet 17 fixedly connected to the side wall of the sedimentation tank 2, a motor 1 fixedly connected to the sedimentation tank 2, a rotating shaft 6 rotatably connected inside the sedimentation tank 2, and the output end of the motor 1 fixedly connected to the rotating shaft 6.

[0032] A brush 3 is rotatably connected to the bottom of the rotating shaft 6. The brush 3 is used to scrub the bottom of the sedimentation tank 2 to prevent sediment from accumulating and hardening at the bottom of the tank.

[0033] A scraper 4 is fixedly connected to the upper end of the rotating shaft 6. The scraper 4 is at a 30° angle to the water surface to clean the floating scum. A scum collection ring 5 is fixedly connected to the top of the sedimentation tank 2. The scum collection ring 5 is annular and has a groove. A scum collection port 7 is opened inside the scum collection ring 5. A conveying pipe 8 is fixedly connected to the scum collection ring 5. The scum collection port 7 and the conveying pipe 8 are interconnected.

[0034] This special angle design can effectively scrape the scum floating on the water surface into the scum collection ring 5 at the top of the sedimentation tank 2. The scum collection ring 5 is annular and has grooves. After the scum is scraped in, it enters the conveying pipe 8 through the scum collection port 7 opened inside the scum collection ring 5. The conveying pipe 8 then transports the scum to the subsequent treatment stage.

[0035] A water pump 10 is placed on the right side of the sedimentation tank 2, and a support 13 is placed on the right side of the water pump 10. Two reaction tanks 12 are fixedly connected to the support 13, and an activated carbon filter screen 11 is fixedly connected inside the upper reaction tank 12.

[0036] The activated carbon filter 11 utilizes the adsorption properties of activated carbon to adsorb organic pollutants, pigments, odors and other impurities in wastewater, further purifying the water quality. The upper reaction tank 12 has a biochemical treatment module 16 fixedly connected to its side wall.

[0037] The microbial community in the biochemical treatment module 16 decomposes the organic matter in the wastewater through biodegradation, converting it into harmless carbon dioxide and water. An asbestos mesh filter 14 is fixedly connected inside the lower reaction tank 12, and a collection box 15 is placed below the support 13. The asbestos mesh filter 14 can filter and intercept residual small particles and suspended solids in the wastewater, ensuring that the wastewater reaches a high purification standard.

[0038] A water pipe 9 is fixedly connected to the sedimentation tank 2. The other end of the water pipe 9 is connected to the upper reaction tank 12 of the support 13. A water pump 10 is installed on the water pipe 9.

[0039] Working principle: Wastewater generated during the production of baijiu (Chinese liquor) flows into sedimentation tank 2 through wastewater inlet 17. After the wastewater enters sedimentation tank 2, motor 1 starts and drives rotating shaft 6 to rotate. This causes brush 3, which is fixed at the bottom of rotating shaft 6, to scrub the bottom of sedimentation tank 2, preventing sediment from accumulating and hardening at the bottom. At the same time, scraper 4 at the top of rotating shaft 6 rotates synchronously with rotating shaft 6. Scraper 4 forms a 30° angle with the water surface. This special angle design can effectively scrape the floating scum on the water surface into the scum collection ring 5 at the top of sedimentation tank 2. The scum collection ring 5 is annular and has grooves. After the scum is scraped in, it enters the conveying pipe 8 through the scum collection port 7 opened inside the scum collection ring 5. The conveying pipe 8 then transports the scum to the subsequent processing stage.

[0040] After initial solid-liquid separation is completed in sedimentation tank 2, the settled wastewater is pumped through water pipe 9 by water pump 10 to the upper reaction tank 12 on support 13. After entering the upper reaction tank 12, the wastewater first passes through the activated carbon filter 11 fixedly connected inside. The activated carbon filter 11 uses the adsorption characteristics of activated carbon to adsorb organic pollutants, pigments, odors and other impurities in the wastewater, further purifying the water quality. At the same time, the biochemical treatment module 16 fixedly connected to the side wall of the upper reaction tank 12 starts to work. The microbial community in the biochemical treatment module 16 decomposes the organic matter in the wastewater through biodegradation, converting it into harmless carbon dioxide and water.

[0041] The wastewater, after being treated by the activated carbon filter 11 and the biochemical treatment module 16, flows into the lower reaction tank 12. The asbestos mesh filter 14, which is fixedly connected inside the lower reaction tank 12, can filter and intercept residual small particles and suspended solids in the wastewater, ensuring that the wastewater reaches a high purification standard. Finally, the water, after being purified through multiple treatments, flows from the lower reaction tank 12 into the collection box 15 placed below the support 13, completing the entire process of treating the wastewater from the liquor production. The treated water can be used or discharged reasonably according to actual needs.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
