Embodiment 1
[0016] The bacterial agent for domestic sewage treatment of the present invention comprises the following components by weight ratio: 10 parts of polyacrylamide, 9 parts of polyethyleneimine, 18 parts of silicon dioxide and 23 parts of composite microorganisms.
[0017] The composite microorganisms include 20 parts of Bacillus subtilis, 15 parts of Pseudomonas aeruginosa, 15 parts of Bacillus cereus, 25 parts of Candida lipolytica, 20 parts of nitrifying bacteria and 24 parts of Paracoccus denitrification by weight.
[0018] The strains in the complex microorganisms were activated and expanded respectively. The culture medium was: 1% yeast extract, 1.5% peptone, 0.5% glucose, NH 4 Cl 2 0.5%, K 2 HPO 4 0.5%, the balance is water, and the medium is sterilized at 121°C for 20 minutes.
[0019] After activating and expanding the culture of each strain in the composite microorganisms, they are respectively inoculated into the culture medium of mixed strains at a volume percentag...
