Problems solved by technology

[0003] The main problem of wastewater treatment is that the one-time investment is too large, or the daily operation cost is too high, most manufacturers cannot afford it, and have to maintain the status quo of excessive discharge for a long time
The applicant's previous research was to use wastewater as a fertilizer, which is suitable for enterprises with fertilizer production qualifications and capabilities, but for other amino acid production enterprises, it cannot achieve the purpose of producing fertilizers
At present, the research is hot on the treatment of wastewater with biological agents, which have the advantages of low cost and no secondary pollution, but have unreasonable microbial compatibility, low treatment efficiency, and microbial carriers have poor internal mass transfer and are not easy to transmit light. Small specific surface area, short service life and other defects; biological agents need to be put in many times, which increases the cost, and the large amount of dosing produces a large amount of sludge, which is not easy to handle

Embodiment 3

[0053] The waste water treatment effect test of the composite bacterial agent prepared by the embodiment of the present invention 2:

[0054] The fermented waste water, which removes fermented cells, polysaccharides and polysaccharides, was used as the treated sample for the test.

[0055] Control group 1: use sawdust carrier; the type of microorganisms is the same as that of the test group; treatment method: after three days of continuous dosing, 5g / m3 per day, and then stand for six days, the detection and treatment results are shown in Table 1.

[0056] Control group 2: The carrier is the same as in Example 2, the difference is that only four kinds of bacteria are added, and no compound algae solution is added; treatment method: add 5g / cubic meter on the first day, and then stand for six days to detect the treatment results See Table 1.

[0057] Test group: the composite bacterial agent prepared in Example 2 of the present invention; treatment method: after one day of dosi...

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a preparation process of a composite bacterial agent for repairing amino acid fermentation wastewater. Background technique [0002] In industrial production, wastewater containing a large amount of amino acids is a kind of organic wastewater with extremely high concentration, which has high concentration of organic matter, high concentration of ammonia nitrogen, SO 4 2- or Cl - It is difficult to handle because of its high concentration and low pH. Although the waste water can remove more than 90% of COD after being treated by bacteria separation, yeast production, anaerobic fermentation, Cr , but the COD of wastewater Cr , The ammonia nitrogen content is still not up to the sewage discharge standard stipulated by the state. A considerable part of these organic waste water is directly discharged into rivers, which not only seriously pollutes the environme...
