The device breaks the bubbles generated by acidification to make the acidification reaction more sufficient and thorough, thereby improving the efficiency and quality of the acidification link in the waste liquid treatment process and ensuring the effective treatment of the waste liquid used in the production of L-asparagine.

[0022] A suction pipe 15 is fixedly connected to the top of the acidification tank 2, and a carbon board box 16 is fixedly connected to the other end of the suction pipe 15. A plurality of activated carbon plates 17 are installed on the carbon board box 16. A suction pipe 2 18 is fixedly connected to the carbon board box 16, and a suction pump 19 is fixedly connected to the other end of the suction pipe 2 18. A washing tower 20 is fixedly connected to the suction pump 19. A supporting foot 21 is fixedly connected to the bottom of the washing tower 20. The suction pipe 15 is also connected to the aerobic tank 24 and the anaerobic tank 25, and can absorb the waste gas generated during the treatment process. The waste gas will first enter the carbon board box 16 to clean the tiny particles in the waste gas, and then enter the washing tower 20 through the suction pipe 2 18.

[0023] A waste liquid pipe 22 is disposed on the left side of the pretreatment tank 1 , and a filter tank 23 is disposed inside the pretreatment tank 1 . Waste liquid is introduced into the treatment device from the waste liquid pipe 22 , and the filter tank 23 pre-filters the waste liquid and communicates with the acidification tank 2 .

[0024] An aerobic tank 24 is arranged on the right side of the pretreatment tank 1, an anaerobic tank 25 is arranged on the right side of the aerobic tank 24, a sedimentation tank 26 is arranged on the right side of the anaerobic tank 25, and a discharge port 27 is opened on the right side of the sedimentation tank 26.

At the same time, the air bag 14 on the rotating rod 12 fixedly connected to the outer surface of the lifting ring 11 has buoyancy and can adjust the height according to the water level. When adapting to the height of the waste liquid surface, the meshing ring 10 slides on the meshing edge 8.
