Embodiment 1
[0037] A method for treating sewage in coal chemical synthesis of ammonia, comprising the steps of:
[0038] Step 1) preparation of microbial preparation, step 2) precipitation and oil separation, step 3) adjustment of pH, step 4) preparation of carbon source, step 5) microbial oxidation, and step 6) preparation of feed protein;
[0039] Specifically, include the following steps:
[0040] Step 1) Preparation of microbial preparations: Bacillus licheniformis, Acinetobacter baumannii, Rhodococcus, Sphingomonas and Pseudomonas fluorescens were cultured to a concentration of 1×10 8 Bacteria solution per ml, mixed according to the volume ratio of 1:1:2:3:3, then mixed with the carrier according to the mass ratio of 1:1 and stirred evenly, and finally dried at low temperature at 30°C. The water content is 10%; that is, the carrier is prepared by mixing diatomite and chitosan according to the mass ratio of 1:1;
[0041] Step 2) Sedimentation and oil separation: Cool the sewage to 2...

[0049] Specifically, include the following steps:
[0050] Step 1) Preparation of microbial preparations: Bacillus licheniformis, Acinetobacter baumannii, Rhodococcus, Sphingomonas and Pseudomonas fluorescens were cultured to a concentration of 1×10 8 Bacteria solution per ml, mixed according to the volume ratio of 1:1:2:3:3, then mixed with the carrier according to the mass ratio of 1:1 and stirred evenly, and finally dried at low temperature at 30°C. The water content is 10%; that is, the carrier is prepared by mixing diatomite and chitosan according to the mass ratio of 1:1;
[0051] The Bacillus licheniformis is CCTCC NO.M206082 (CN101037659A); ...
Embodiment 3
[0062] Taking the coal chemical industry sewage of our company as an example, the sewage treatment effect of Example 2 was tested, and all indicators reached the ideal discharge standard. The detection indicators of sewage are shown in Table 1:
[0063] Table 1
[0064] Before treatment (mg / L) After treatment (mg / L) Removal rate (%) COD 1059.3 19.1 98.2% NH3-N 325.7 6.9 97.9% Sulfide 56.2 2.6 95.4%
