Embodiment 1

[0032] Take 28 parts of actinomycetes, 22 parts of indigenous bacteria, 25 parts of nitrifying bacteria, 28 parts of denitrifying bacteria, 21 parts of phosphorus accumulating bacteria, 16 parts of bifidobacteria, mix them evenly, put them in 20 parts of clean soil and stir them evenly The soil containing the strains was obtained, and 3-month-old healthy and mature earthworms cleaned with sterile water were placed in the soil containing the strains for cultivation. The cultivation time was 12 days and then the earthworms were separated to obtain the mixed strains. earthworm droppings;

[0033] Microbial agent carrier material preparation: Take 20 parts of diatomite and pass through a 200-mesh sieve, then add 5mol / L hydrochloric acid solution to soak it completely, treat it at a constant temperature of 83°C for 85min, stir continuously, filter with suction, and wash repeatedly until Neutral, dry the filtered diatomite at a temperature of 105°C to obtain dry diatomite; take 2.2 ...

Embodiment 2

[0036] Take 20 parts of actinomycetes, 18 parts of native bacteria, 22 parts of nitrifying bacteria, 20 parts of denitrifying bacteria, 20.5 parts of phosphorus accumulating bacteria, 15 parts of bifidobacteria, mix them evenly, put them in 23 parts of clean soil and stir them evenly The soil containing the strains was obtained, and 3-month-old healthy and mature earthworms cleaned with sterile water were placed in the soil containing the strains for cultivation. After the cultivation time was 13.5 days, the earthworms were separated, and the mixed strains were obtained. earthworm droppings;

[0037] Preparation of microbial agent carrier material: Take 30 parts of diatomite and pass through a 200-mesh sieve, then add 5mol / L hydrochloric acid solution to soak it completely, treat it at a constant temperature of 85°C for 90min, and continuously stir, suction filter, and wash repeatedly until Neutral, dry the filtered diatomite at a temperature of 105°C to obtain dry diatomite; ...

Embodiment 3

[0040] Take 22 parts of actinomycetes, 19 parts of indigenous bacteria, 28 parts of nitrifying bacteria, 30 parts of denitrifying bacteria, 22 parts of phosphorus accumulating bacteria, 20 parts of bifidobacteria, mix them evenly, put them in 25 parts of clean soil and stir them evenly The soil containing the strains was obtained, and 3-month-old healthy and mature earthworms cleaned with sterile water were placed in the soil containing the strains for cultivation. The cultivation time was 13 days and then the earthworms were separated to obtain the mixed strains. earthworm droppings;

[0041] Microbial agent carrier material preparation: Take 22 parts of diatomite and pass through a 200-mesh sieve, then add 5mol / L hydrochloric acid solution to soak it completely, treat it at a constant temperature of 80°C for 86min, stir continuously, filter with suction, and wash repeatedly until Neutral, dry the filtered diatomite at a temperature of 105°C to obtain dry diatomite; take 2.5 ...

Abstract

The invention belongs to the technical field of wastewater treatment and particularly relates to a microbial agent suitable for treating urban wastewater and a preparation method thereof. The microbial agent comprises Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, saccharomycetes, lactic acid bacteria, acetic acid bacteria, photosynthetic bacteria, Actinobacteria, indigenous bacteria, nitrifying bacteria, denitrifying bacteria, phosphorus-accumulating bacteria, Rhodospirillum, Thiobacillus denitrificans, Sphingobacteria, Alcaligenes faecalis, Bifidobacterium, brown rot fungi,Geotrichum candidum, Mucor, Aspergillus oryzae, and Penicillium diversum. The preparation method includes: mixing well Actinobacteria, indigenous bacteria, nitrifying bacteria, denitrifying bacteria,phosphorus-accumulating bacteria and Bifidobacterium, adding the mixture into clean soil, farming earthworms with the soil for 12-14 days, and isolating the earthworms and the soil to obtain earthwormcast containing the mixed bacteria; mixing the earthworm cast containing the mixed bacteria and other bacteria, and immobilizing to obtain the microbial agent.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a microbial bacterial agent which can be used to treat urban sewage and a preparation method thereof. Background technique [0002] With the rapid development of the urban economy, the amount of sewage produced by life and production in the city is also increasing, and the treatment of urban sewage is also a very important issue. The failure of urban domestic sewage to be effectively treated will not only affect the urban environment, but may also cause a decline in the overall operating quality of the city, especially affecting the normal life of urban residents. Strengthening the treatment of urban domestic sewage and improving the treatment effect of urban sewage can ensure the quality of urban life and healthy development. At present, with the complexity of urban life, there are more and more pollutants in the sewage discharged, and the climate changes throughout th...
