Embodiment 1
[0037] The treatment process of monosodium glutamate fermentation waste water is characterized in that, comprises the following steps:
[0038] (1) After passing the MSG fermentation wastewater through the grid, it enters the grit chamber, and the sewage separated from sand and water enters the primary sedimentation tank, and passes through the primary sedimentation tank to promote the buoyancy of oil in the wastewater and reduce the content of suspended solids;
[0039] (2) Preparation of physical adsorbent
[0040] Mix according to the mass ratio of forsterite powder, shell powder, perlite powder, and pore-forming agent in a mass ratio of 3:1:1:4, stir evenly, place in a granulator, and add 22% (weight) of water to the mixture , granulated to obtain a spherical green body with a particle size of 3-5mm; dried at 100°C for 20 hours, and calcined at 980°C for 1 hour to obtain a physical adsorbent.

Embodiment 2
[0059] The treatment process of monosodium glutamate fermentation waste water is characterized in that, comprises the following steps:
[0060] (1) After passing the MSG fermentation wastewater through the grid, it enters the grit chamber, and the sewage separated from sand and water enters the primary sedimentation tank, and passes through the primary sedimentation tank to promote the buoyancy of oil in the wastewater and reduce the content of suspended solids;
[0061] (2) Preparation of physical adsorbent
[0062] Mix according to the mass ratio of forsterite powder, shell powder, perlite powder, and pore-forming agent in a mass ratio of 4:2:2:5, stir evenly, place in a granulator, and add 25% (weight) of water to the mixture , granulated to obtain a spherical green body with a particle size of 3-5mm; dried at 100°C for 20 hours, and calcined at 980°C for 1 hour to obtain a physical adsorbent.
[0063] (3) The wastewater treated by the primary sedimentation tank enters the...
Embodiment 3
[0079] Embodiment 3 Treatment example of waste water effect
[0080] Take the Fufeng production workshop, extract waste water from monosodium glutamate, and enter the sewage treatment system according to the method of embodiment 1-2 respectively, and take samples to measure COD, ammonia nitrogen, and total nitrogen data;
[0081] Compared with Example 1, control group 1 does not add physical adsorbent; compared with Example 1, control group 2 does not add composite bacterial agent. Sampling and determination of COD, ammonia nitrogen, SS, and clarity test data are shown in Table 1:
