Embodiment 1
[0026] Embodiment 1: a kind of water treatment compound active bacterial agent, comprises following composition:
[0027] Compound flora (mass ratio):
[0028] Nitrifying bacteria 40%, denitrifying bacteria 10%, Bacillus 20%, Pseudomonas 5%, activase 10%, photosynthetic bacteria 10%, Gandobacterium 5%;
[0029] Inducing base (mass ratio):
[0030] The mass fraction is amino acid 5%, yeast extract 5%, chitin 1%, chitooligosaccharide 0.1‰, glucose 88.99%;
[0031] The amount of the inducing base is 20% of the mass of the composite flora, and the two are evenly mixed together to obtain the composite active bacterial agent of the present invention.
[0032] The waste water from the production of thiophanate-methyl of a certain company was taken as the treatment object. In the waste water, the concentration of COD was 9000 mg / L, methyl sulfide was not detected, the concentration of dimethyl disulfide was 350 mg / L, and the odor was strong.
[0033] Take 100L of the above-mentione...
Embodiment 2
[0035] Embodiment 2: a kind of water treatment compound active bacterial agent, comprises following composition:
[0036] Compound flora (mass ratio):
[0037] Nitrifying bacteria 55%, denitrifying bacteria 15%, Bacillus 5%, Pseudomonas 50%, activase 10%, photosynthetic bacteria 7%, Gandobacterium 3%;
[0038] Inducing base (mass ratio):
[0039] The mass fraction is amino acid 8%, yeast extract 10%, chitin 2%, chitosan oligosaccharide 0.3‰, glucose 79.97%;
[0040] The amount of the inducing base is 15% of the mass of the composite flora, and the two are evenly mixed together to obtain the composite active bacterial agent of the present invention.
[0041] Taking the metallurgy discharged from a chemical plant as the treatment object, the wastewater mainly contains inorganic salts such as sodium chloride, sodium sulfate, sodium carbonate and sodium bicarbonate, among which, Na + ≤20000mg / L,SO 4 2- ≤30000mg / L, Cl - ≤20000mg / L, CO 3 2- ≤4000mg / L, HCO 3 - ≤2000mg / L, ot...
Embodiment 3
[0043] Embodiment 3: a kind of water treatment compound active bacterial agent, comprises following composition:
[0044] Compound flora (mass ratio):
[0045] Nitrifying bacteria 50%, denitrifying bacteria 12%, Bacillus 10%, Pseudomonas 8%, activase 8%, photosynthetic bacteria 7%, Gandobacterium 5%;
[0046] Inducing base (mass ratio):
[0047] The mass fraction is amino acid 6%, yeast extract 8%, chitin 2%, chitooligosaccharide 0.2‰, glucose 83.98%;
[0048] The consumption of inducing base is 18% of composite flora mass, and the two are evenly mixed as one to obtain composite active bacterial agent of the present invention.
[0049] Taking domestic sewage as the treatment object, the pH value of the domestic sewage is 6-9, the total phosphorus content is 4-15mg / l, the ammonia nitrogen content is 55-100mg / L, the COD concentration is 200-400mg / L, and the BOD concentration is 100 -200mg / L.
[0050] Take 100L of the above-mentioned domestic sewage, add 100g of compound active...
