[0002] Most liquor production uses sorghum, wheat, corn and other raw materials, and adopts basic processes such as artificial cultivation of old cellars, fermentation, distillation, graded storage, and careful blending. Liquor wastewater refers to industrial wastewater generated from production to storage and aging. According to the degree of pollution, it can be divided into two parts. One part is low-concentration wastewater, including cooling water, bottle washing water, site flushing water, etc. Its pollutant concentration is far lower than the national emission standard, and it can generally be recycled or directly discharged; the other part is high-concentration wastewater, such as distillation pot bottom water, koji making section wastewater, fermentation tank blind ditch water, distillation section ground flushing water, underground wine warehouse leakage water, "xiasha" and "rough sand" process raw material flushing, soaking discharge water, etc. These wastewaters have the following characteristics: high organic matter content: a large amount of organic matter is produced during the production of liquor, such as residual alcohol, protein, sugar and starch; many suspended solids: the suspended solids in the wastewater mainly come from the dregs of the raw materials, lees and lime; strong acidity: a large amount of acidic substances are produced during the fermentation of liquor, resulting in a generally low pH value of the wastewater; high temperature: since heating is required during the distillation and fermentation process, the temperature of the wastewater is high; contains a variety of microorganisms: a large number of microorganisms are produced during the fermentation process, and these microorganisms will be discharged with the wastewater. For these high-concentration wastewaters, if they are discharged directly without treatment, they will cause serious pollution to the environment.

[0003] At present, the main biochemical treatment methods used for the treatment of liquor wastewater include aerobic treatment, anaerobic treatment and mixed treatment. Although these methods can remove organic matter and suspended solids in wastewater to a certain extent, there are some problems: the existing treatment methods have problems such as low efficiency, waste of resources, secondary pollution and high operating costs.

[0029] like Figure 1-Figure 2 As shown, the utility model provides a liquor production wastewater recovery and treatment pool, comprising: a filtration pool 1, a pH adjustment pool 2, an anaerobic reactor 3, a sedimentation pool 4, an A / O treatment pool 5, a secondary sedimentation pool 6 and a phosphorus removal pool 7, and the filtration pool 1, the pH adjustment pool 2, the anaerobic reactor 3, the sedimentation pool 4, the A / O treatment pool 5, the secondary sedimentation pool 6 and the phosphorus removal pool 7 are connected in sequence through pipelines.

[0030] A coarse grid 101, a first fine grid 102, a second fine grid 103 and a turbidity meter 104 are provided in the filter tank 1. The coarse grid 101 and the first fine grid 102 are vertically installed, and the second fine grid 103 is horizontally installed.

The turbidity meter 104 is arranged on the side wall of the filter tank 1 and is located above the second fine grid 103. The connection position between the pipeline and the filter tank 1 is located above the turbidity meter 104.

[0031] The pH regulating tank 2 is connected to the pH neutralizing tank 8 , and a pH sensor is provided in the pH regulating tank 2 .

[0032] In the utility model, liquor production wastewater is discharged after passing through a filtering tank 1, a pH regulating tank 2, an anaerobic reactor 3, a sedimentation tank 4, an A / O treatment tank 5, a secondary sedimentation tank 6 and a dephosphorization tank 7 in sequence.

[0033] In some embodiments of the present application, the recovery and treatment tank further includes a sludge tank 9, which is connected to the secondary sedimentation tank 6 and the phosphorus removal tank 7 through pipelines.

[0034] In this embodiment, a large amount of sludge is generated in the process of treating the wastewater from liquor production. The sludge contains a large amount of organic matter and microorganisms. If not properly treated, the sludge may pollute the environment. By setting up a sludge pool 9, the sludge is recycled and treated. At the same time, the sludge pool 9 is connected to the secondary sedimentation tank 6 and the dephosphorization tank 7 because a large amount of sludge is also generated after the secondary sedimentation tank 6 and the dephosphorization tank 7, which needs to be collected.

[0035] In some embodiments of the present application, the sludge tank 9 is connected to the filter press 10 via a pipeline.

[0036] In this embodiment, the filter press 10 uses a special filter medium to apply a certain pressure to the object, so that the liquid is dialyzed out of the mechanical equipment, which is a commonly used solid-liquid separation equipment. The sludge tank 9 is connected to the filter press 10, and the sludge can be dehydrated by the filter press 10, thereby reducing the volume of the sludge and facilitating the treatment of the sludge.

[0037] In some embodiments of the present application, the recovery treatment tank further includes a first sludge pump 11 , which is disposed between the anaerobic reactor 3 and the sedimentation tank 4 , and is used to transport the sludge in the sedimentation tank 4 to the anaerobic reactor 3 .

[0038] In this embodiment, a sedimentation tank 4 is arranged behind the anaerobic reactor 3, which can effectively prevent the effluent from sludge due to fluctuations in the quality and quantity of the influent water, and avoid the sludge-containing wastewater from entering the subsequent treatment tank. By arranging a first sludge pump 11, the sludge generated in the sedimentation tank 4 is transported to the anaerobic reactor 3, so that the lost sludge returns to the anaerobic reactor 3, thereby improving the treatment efficiency of the anaerobic reactor 3.

O aerobic tank 503: in an environment with sufficient dissolved oxygen, aerobic microorganisms are used to degrade organic matter in the sewage, and ammonia nitrogen is converted into nitrate nitrogen through nitrification. At the same time, phosphorus in the sewage can also be absorbed under aerobic conditions to achieve phosphorus removal. A microaerobic tank 502: between aerobic and anaerobic, there is a certain amount of dissolved oxygen, but it is not enough to support a complete nitrification process. Denitrification can be carried out in a microaerobic environment, and the nitrate nitrogen produced in the aerobic section is reduced to nitrogen gas for discharge, thereby achieving the effect of denitrification.

[0041] In some embodiments of the present application, the recovery and treatment tank further includes a second sludge pump 12 , which is disposed between the A anaerobic tank 501 and the secondary sedimentation tank 6 , and is used to transport the sludge in the secondary sedimentation tank 6 to the A anaerobic tank 501 .

[0042] In this embodiment, a second sludge pump 12 is provided to transport the sludge in the secondary sedimentation tank 6 to the A anaerobic tank 501 to maintain the denitrification and phosphorus removal functions of the A / O treatment tank 5 and improve the treatment efficiency of the A / O treatment tank 5 .

[0043] In some embodiments of the present application, Figure 3 As shown, the sides of the A anaerobic tank 501, the A microaerobic tank 502 and the O aerobic tank 503 are all provided with stirring mechanisms 13.

[0044] In this embodiment, by providing a stirring mechanism 13, the sewage and various types of biological flora can be better contacted and cooperated, thereby promoting the treatment efficiency of the A / O treatment tank 5. The stirring mechanism 13 includes a stirring motor, a stirring shaft and a stirring blade, the stirring blade is installed on the stirring shaft, the stirring shaft is connected to the output shaft of the stirring motor, and the stirring motor is used to drive the stirring shaft and the stirring blade to rotate.

[0045] In some embodiments of the present application, an aeration mechanism 14 is provided at the bottom of the A anaerobic tank 501 , the A microaerobic tank 502 and the O aerobic tank 503 .

[0046] In this embodiment, organic matter, nitrogen and phosphorus removal can be removed by controlling the three different environmental conditions of the A anaerobic pool 501, the A microaerobic pool 502 and the O aerobic pool 503 and the organic coordination of different types of microbial flora. The aeration mechanism includes an aeration pipe and an aeration fan, the aeration fan is connected to the aeration pipe, and an air outlet is provided on the aeration pipe, and a waterproof breathable membrane is provided at the air outlet.
