Embodiment 1
[0032] (1) Take the monosodium glutamate wastewater produced in the Fufeng production workshop, and the wastewater enters the pre-anaerobic pool UASB, and the hydraulic retention time is controlled to be 30h, and the temperature is 35°C, so that the macromolecular substances are broken into small molecular substances, and the organic nitrogen is converted into Inorganic nitrogen, the effluent enters the sedimentation tank;
[0033] (2) Sedimentation tank Adding biological agents for advanced treatment, the biological agents include the following raw materials in parts by weight:
[0034] 8 parts of aerobic denitrifying bacteria, 8 parts of Bacillus, 7 parts of Aspergillus niger, 7 parts of Rhodococcus, 5 parts of Alcaligenes faecalis, 5 parts of Streptomyces rubrum, and 3 parts of Candida albicans.
[0035] The aerobic denitrifying bacteria are aerobic denitrifying bacteria ( Paracoccus pantotrophus ) ATCC 35512.
[0036] The bacillus is a bacillus ( Bacillus sp. ) CGMCC N...
Embodiment 2
[0048] (1) Take the monosodium glutamate wastewater produced in the Fufeng production workshop, and the wastewater enters the pre-anaerobic pool UASB, and the hydraulic retention time is controlled to be 30h, and the temperature is 35°C, so that the macromolecular substances are broken into small molecular substances, and the organic nitrogen is converted into Inorganic nitrogen, the effluent enters the sedimentation tank;
[0049] (2) Sedimentation tank Adding biological agents for advanced treatment, the biological agents include the following raw materials in parts by weight:
[0050] 10 parts of aerobic denitrifying bacteria, 10 parts of Bacillus, 9 parts of Aspergillus niger, 9 parts of Rhodococcus, 8 parts of Alcaligenes faecalis, 8 parts of Streptomyces rubrum, and 5 parts of Candida albicans.
[0051] The aerobic denitrifying bacteria are aerobic denitrifying bacteria ( Paracoccus pantotrophus ) ATCC 35512.
[0052] The bacillus is a bacillus ( Bacillus sp. ) CGMCC...
Embodiment 3
[0063] Embodiment 3 Treatment example of waste water effect
[0064] Take the Fufeng production workshop, glutamic acid extracts waste water, 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;
[0065] Compared with Example 1, the control group 1 did not add complex bacterial agents; compared with Example 1, the control group 2 had only wheat bran as the adsorbent carrier. Sampling and determination of COD, ammonia nitrogen, and total nitrogen data, the test data are shown in Table 1:
[0066] Table 1
[0067] control group 1 control group 2 Example 1 group Example 2 group COD average removal rate 8.3% 55.2% 99.3% 99.4% Ammonia nitrogen average removal rate 9.7% 47.4% 99.1% 99.7%
