Embodiment 1
[0032] (1) Take monosodium glutamate wastewater produced by an enterprise in Linyi City, and the wastewater enters the pre-anaerobic pool UASB. 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) Add biological preparations to the sedimentation tank for advanced treatment, and the biological preparations include the following raw materials in parts by weight:
[0034] 12 parts of aerobic denitrifying bacteria, 12 parts of Paenibacillus polymyxa, 10 parts of Aspergillus niger, 10 parts of Rhodococcus, 9 parts of Alcaligenes faecalis, 7 parts of Streptomyces rubrum, 7 parts of Candida albicans, nitrosative bacteria 5 servings.
[0035] The aerobic denitrifying bacteria is Paracoccus pantotrophus ATCC35512.
[0036] The Paenibacillus polymyxa is Pae...
Embodiment 2
[0049] (1) Take the monosodium glutamate wastewater produced by a production workshop in Linyi City, and the wastewater enters the pre-anaerobic pool UASB, and the hydraulic retention time is controlled to 30h, and the temperature is 35°C, so that the macromolecular substances are broken into small molecular substances, and the organic nitrogen is transformed. Become inorganic nitrogen, and the effluent enters the sedimentation tank;
[0050] (2) Add biological preparations to the sedimentation tank for advanced treatment, and the biological preparations include the following raw materials in parts by weight:
[0051] 15 parts of aerobic denitrifying bacteria, 15 parts of Paenibacillus polymyxa, 12 parts of Aspergillus niger, 12 parts of Rhodococcus, 10 parts of Alcaligenes faecalis, 10 parts of Streptomyces rubrum, 10 parts of Candida albicans, nitrosative bacteria 7 servings.
[0052] The aerobic denitrifying bacteria is Paracoccus pantotrophus ATCC35512.
[0053] The Paen...
Embodiment 3
[0065] Embodiment 3 treats the example of waste water effect
[0066] Get monosodium glutamate waste water, according to embodiment 1-2 method kettle bottom material enters sewage treatment system respectively, sampling measures COD, ammonia nitrogen, total nitrogen data;
[0067] Compared with Example 1, the control group 1 did not add compound 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 as follows in Table 1:
