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 re

[0052] Example 3

[0053] The wastewater treatment effect test of the composite bacterial agent prepared in Example 2 of the present invention:

[0054] The experiment was carried out with the fermentation wastewater from which the fermentation bacteria, polysaccharides and polysaccharides were removed as the treated samples.

[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 still 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, except that only four kinds of bacteria are added, and no compound algae liquid is added; processing method: add 5g / m3 on the first day, then stand for six days, check the processing results See Table 1.

[0057] Test group: the composite microbial agent prepared in Example 2 of the present invention; processing method: after...

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...
