specific Embodiment approach 1

[0012] Specific implementation mode one: (see figure 1 ) The storage device for anaerobic granular sludge in the beer industry wastewater treatment in this embodiment is made of corrosion-resistant FRP and PVC, and is composed of a tank 1, a mud inlet pipe 2, a mud outlet pipe 3, an air outlet pipe 4, and a water sealing device 5 , liquid outlet pipe 6, liquid inlet funnel 8, the first liquid inlet pipe 9 and the second liquid inlet pipe 10; The air port communicates with the air inlet of the air outlet pipe 4, the air outlet of the air outlet pipe 4 extends into the bottom of the water seal device 5, the liquid outlet on the top of the tank 1 communicates with the liquid inlet of the liquid outlet pipe 6, and the mud outlet at the bottom of the tank 1 The mouth is communicated with the mud inlet of the mud outlet pipe 3, the liquid outlet of the first liquid inlet pipe 9 is communicated with the liquid inlet on the upper part of the liquid inlet funnel 8, and the liquid outle...

specific Embodiment approach 2

[0014] Specific implementation mode two: (see figure 1 ) The difference between this embodiment and the specific embodiment one is: the first partition 7 and the second partition 11 are also arranged in the tank 1 of the storage device for anaerobic granular sludge in the treatment of beer industry wastewater, and the first partition 7 and the two sides of the second partition 11 are fixedly connected with the inner wall of the tank 1 respectively, and the second liquid inlet pipe 10 extends into the inside of the tank 1 through the second partition 11 from the upper, middle and lower parts of the tank 1 respectively. Others are the same as in the first embodiment.

[0015] A baffle is added in the tank 1 to increase the turbulence of the water flow without creating a dead zone, and to form a good sedimentation zone to help the water get rid of too much granular sludge.

specific Embodiment approach 3

[0016] Specific embodiment three: the preservation method of anaerobic granular sludge in the beer industry wastewater treatment in this embodiment is realized by the following steps: one, anaerobic granular sludge is stored in the anaerobic granular sludge in the brewery wastewater treatment process In the storage device, adjust the pH value of the nutrient solution to 6.8-7.5 and then pass it into the anaerobic granular sludge storage device. The total amount of culture solution is 2.5-4.5% of the sludge volume.

[0017] In this embodiment, the gas and supernatant in the container are exported at any time during the preservation process. Anaerobic granular sludge refers to the remaining sludge that grows and reproduces in the process of brewery wastewater treatment.

Abstract

The invention relates to a device for storing anaerobic granular sludge and a method thereof, particularly to a device for storing anaerobic granular sludge in beer industry wastewater treatment and a method thereof. The invention solves the problems of the prior anaerobic granular sludge technique, including complex process, high cost, reduced treatment specificity of original granular sludge, and high mortality rate and remarkably reduced activity of anaerobic granular activated sludge fed into a target anaerobic device. The sludge outlet port of a sludge inlet pipe of the inventive device communicates with a sludge inlet port at the top of the tank, and the sludge outlet port at the bottom of the tank communicates with the sludge inlet port of the sludge outlet pipe. The storage method comprises the steps of: storing the anaerobic granular sludge used in the beer wastewater treatment process in the inventive anaerobic granular sludge storage device, introducing nutrient solution, and storing. The inventive device has the advantages of simple structure, small floor area, and flexible application manner. The inventive method retains the treatment specificity and original activity of the granular sludge; and has the advantages of high survival rate, simple process, low cost, convenient application, and applicability to industrial production.

Description

technical field [0001] The invention relates to a storage device and method for anaerobic granular sludge. Background technique [0002] my country's beer industry has become an important industry in the national economy. The beer industry has developed rapidly, and the beer output has increased significantly compared with the past. It has become one of the five largest beer producing countries in the world. However, after investigation, the wastewater treatment of most breweries in my country has not reached the national standard, causing serious pollution to the environment. [0003] According to the characteristics of non-toxic and harmful high-concentration organic wastewater of beer, anaerobic treatment technology is generally used at home and abroad for treatment, and the key link of anaerobic treatment method is to add active anaerobic bacteria to the beer wastewater to be treated , for inoculation and propagation. At present, the beer wastewater treatment technolog...
