[0002] The wastewater from tobacco production consists of production wastewater and domestic sewage. The amount of wastewater discharged from tobacco processing is large, and the nicotine, spices, flavors, engine oil and other substances in this type of wastewater are difficult to degrade organic matter, which makes the treatment of tobacco wastewater more difficult. Nicotine is a strong alkaloid that is toxic to the human body and the environment. Therefore, it is very important to treat this type of wastewater.

[0003] The existing technical solution for treating nicotine in tobacco is a treatment process of pretreatment - flotation - anaerobic - aerobic - advanced treatment to solve this problem. Since there are a lot of suspended matter and oil in the wastewater, the suspended matter and oil are decomposed by microorganisms to form sludge during the anaerobic reaction stage. During the process of treating nicotine in the wastewater, the microbial growth process will cause the sludge volume to increase, affecting the sedimentation performance and making the sludge difficult to separate.

[0004] Therefore, it is necessary to design a biological treatment system for nicotine-containing wastewater that can reduce sludge production. Utility Model Content

A drug storage room 22 is installed on the rear side of the stabilizing plate 24. The drug storage room 22 is used to store drugs required for the treatment of nicotine-containing wastewater. A water distribution pipe 2 is provided inside the anaerobic biological treatment room 1. One side of the anaerobic biological treatment room 1 is connected and communicated with the first sampling valve 2001. The anaerobic biological treatment room 1 is installed with a three-phase separator 3 by means of bolt connection at the top. The upper side of the anaerobic biological treatment room 1 is connected and communicated with a pressure gauge 4. The top of the anaerobic biological treatment room 1 is connected and communicated with a biogas pipe 5. The input end of the water distribution pipe 2 is installed with the water inlet system 6. The water distribution pipe 2 runs through the anaerobic biological treatment room 1 and is connected to the water inlet system 6. Then, a water outlet system 7 is installed on one side of the upper part of the anaerobic biological treatment room 1, and it also includes an enzyme-catalyzed degradation barrel 16, an immobilized enzyme 17, a sewage conveying pipe 19 and a second sampling valve 20. The enzyme-catalyzed degradation barrel 16 is installed on the right side of the stabilizing plate 24. A protective plate 18 is installed on the upper part of the enzyme-catalyzed degradation barrel 16 by bolt connection to prevent foreign matter from falling into the enzyme-catalyzed degradation barrel 16 when treating nicotine-containing wastewater. An immobilized enzyme 17 is placed inside the enzyme-catalyzed degradation barrel 16. The immobilized enzyme 17 is formed by fixing the enzyme on a carrier (such as activated carbon, resin, fiber, etc.), which can improve the stability and reusability of the enzyme and increase the service life of the enzyme. The upper part of the enzyme-catalyzed degradation barrel 16 is connected and communicated with the sewage conveying pipe 19, one side of the lower part of the enzyme-catalyzed degradation barrel 16 is connected and communicated with the second sampling valve 20, and the other side of the lower part of the enzyme-catalyzed degradation barrel 16 is connected and communicated with the input end of the water distribution pipe 2.

[0023] See Figure 4 and Figure 5As shown, it also includes an aerobic biological treatment box 10, a water inlet pipe 101, a support frame 11, a mechanical aerator 12, a protective frame 13, a membrane bioreactor 14 and a connecting pipe 15. The aerobic biological treatment box 10 is installed on the left side of the top of the stabilizing plate 24 by means of bolts. A rain shield 23 is installed on the top of the aerobic biological treatment box 10 by bolt connection.

A membrane bioreactor 14 is installed on the left side of the aerobic biological treatment box 10, and a connecting pipe 15 is connected to the membrane bioreactor 14.

[0024] When treating nicotine-containing wastewater, the wastewater is first introduced into the enzyme catalytic degradation barrel 16. The immobilized enzyme 17 in the barrel degrades the oily macromolecular organic matter in the nicotine-containing wastewater and degrades part of the nicotine in the wastewater, thereby reducing the generation of sludge during the subsequent anaerobic reaction. The wastewater in the enzyme catalytic degradation barrel 16 is sampled and tested through the second sampling valve 20. When the wastewater in the barrel reaches the preset treatment standard, the water inlet system 6 and the biogas pipe 5 are opened to allow the degraded nicotine-containing wastewater to enter the anaerobic biogas through the water inlet system 6. Treatment room 1, during this process, the nicotine-containing wastewater is evenly dispersed into the anaerobic biological treatment room 1 under the action of the water inlet system 6, and the gas in the anaerobic biological treatment room 1 is discharged through the biogas pipe 5, and then the biogas pipe 5 is closed to form a closed state in the anaerobic biological treatment room 1. At this time, the nicotine wastewater in the anaerobic biological treatment room 1 is reacted and degraded by microorganisms, and the gas, water and sludge are separated by the three-phase separator 3. At the same time, the pressure gauge 4 detects the gas pressure inside the anaerobic biological treatment room 1. When the anaerobic biological treatment room When the air pressure in the treatment room 1 increases, the biogas pipe 5 is opened to discharge biogas through the biogas pipe 5. The discharged biogas is collected and the wastewater in the anaerobic biological treatment room 1 is sampled and tested through the first sampling valve 2001. When the wastewater in the anaerobic biological treatment room 1 meets the discharge standard, the outlet system 7 is opened to allow the wastewater to enter the aerobic biological treatment tank 10 through the outlet pipe. The mechanical aerator 12 is started to introduce air into the water body and stir and mix the wastewater to increase the solubility of oxygen, thereby maintaining an oxygen-rich environment for the wastewater in the aerobic biological treatment tank 10. Under aerobic conditions, aerobic microorganisms oxidize organic matter in the wastewater into carbon dioxide and water, forming new sludge. At the same time, some more difficult-to-degrade organic matter can also be gradually degraded by aerobic microorganisms. At this time, the membrane bioreactor 14 directly filters clean water from the reactor and discharges it through the connecting pipe 15. At the same time, a high aerobic microorganism concentration is maintained, allowing the aerobic microorganisms to continuously decompose and treat the nicotine wastewater, thereby improving the treatment efficiency of the nicotine-containing wastewater.
