Embodiment 1
[0073] Process flow chart of the present invention is referred to figure 1 . Take the taurine mother liquor with a COD value of about 100,000 mg / L and a total nitrogen of about 4,000 mg / L after ammonia desalination, and dilute it by 1 time. If the solution has a strong ammonia smell, part of the ammonia can be removed by evaporation until there is no ammonia smell. After cooling, add pure water to the scale before the original ammonia removal, adjust the pH to about 7.5 with hydrochloric acid, inoculate 2% Streptomyces rubrum (bio-096964) and 2% Bacillus jelly-like (bio-62117) to control fermentation Conditions, when the growth of the strain is slow, add glucose in an appropriate amount, and maintain the fermentation temperature at 25-30°C. During the fermentation process, after sampling to measure the OD value or wet weight, take the supernatant after centrifugation to measure the COD value and total nitrogen. The results are shown in Table 1 below:

Embodiment 2
[0078] Take the taurine mother liquor with a COD value of about 100,000 mg / L and a total nitrogen of about 4,000 mg / L after ammonia desalination, and dilute it by 1 time. If the solution has a strong ammonia smell, part of the ammonia can be removed by evaporation. After cooling, add purified water Adjust the pH to about 7.5 with hydrochloric acid, inoculate 2% Streptomyces ruberenum (bio-096964) and 2% Halo-loving Actinomycetes (BNCC218473), and control the fermentation conditions. When the strains grow slowly , add glucose in an appropriate amount, and maintain the fermentation temperature at 25-30°C. During the fermentation process, after sampling to measure the OD value or wet weight, after centrifugation, take the supernatant to measure the COD value and total nitrogen. The results are shown in Table 2:

Embodiment 3
[0083] Take the taurine mother liquor with a COD value of about 100,000 mg / L and a total nitrogen of about 4,000 mg / L after ammonia desalination, and dilute it by 1 time. If the solution has a strong ammonia smell, part of the ammonia can be removed by evaporation. After cooling, add purified water To the original scale before ammonia removal, adjust the pH to about 7.5 with hydrochloric acid, inoculate 4% of Streptomyces albicans (bio-18862) and 4% of Pseudomonas stutzeri strains (bio-17137), control the fermentation conditions, when the bacteria When the growth of the species is slow, add glucose in an appropriate amount and maintain the fermentation temperature at 25-30°C. During the fermentation process, after sampling to measure the OD value / wet weight, take the supernatant after centrifugation to measure the COD value and total nitrogen. The results are shown in Table 3 :
