Problems solved by technology

The first is aerobic hazards: due to biodegradation, high-concentration organic wastewater will make the receiving water body anoxic or even anaerobic, and most aquatic organisms will die, resulting in stench, deteriorating water quality and environment
The second is sensory pollution: high-concentration organic wastewater not only makes the water lose its use value, but also seriously affects the normal life of people near the water
The third is toxicity hazards: ultra-high concentration organic wastewater contains a large amount of toxic organic substances, which will continue to accumulate and store in natural environments such as water bodies and soils, and finally enter the human body, endangering human health
However, the anaerobic treatment takes a long time, the scale application is limited, the gas production is unstable, and there are problems such as secondary pollution.

Embodiment 1

[0062] The preparation of embodiment 1 microbial composite bacterial agent

[0063] (1) Fermentation of various bacteria

[0064] Medium: LB;

[0065] Culture conditions: Shake the flask at 37°C until the bacterial concentration is about 10 8 cfu / ml. Usually 2x10 8 ~4x10 8 cfu / ml.

[0066] The slant species of Haitobacter sufflavus Tih-w37, Acinetobacter radioresistant, Bacillus subtilis, Bacillus licheniformis, Saccharomyces cerevisiae, Pallidum, Trichoderma, Geotrichum candidum, Bacillus cereus and Mucor Inoculate into LB liquid medium, and culture each bacteria separately.

[0067] Haitobacter sufflavus Tih-w37 is a microorganism with independent intellectual property rights, which was preserved in the China Center for Type Culture Collection (CCTCC) by Hao Wei, the inventor of the application, and was selected into the National Natural Science and Technology Resource Platform as a new genus.

[0068] Haitobacter sufflavus Tih-w37 was deposited in China Center for T...

Embodiment 2

[0077] Embodiment 2 chicken manure waste water continuous treatment

[0078] Firstly, sterilize the very disgusting and smelly chicken manure wastewater and treat insect eggs. The specific method is as follows:

[0079] According to one thousandth of the total mass of waste water, dimethyl chloride quaternary ammonium salt bactericide (mass fraction is 3%) is added in very disgusting smelly chicken manure waste water. Then in a special 2m with agitator 3 In the waste pit, add the chicken manure waste water (solid content rate is about 5%) of 1000kg, according to the 6 ‰ of chicken manure waste water quality, add the microbial composite bacterium I 6kg that obtains in the embodiment 1, described microbial composite bacterium I The effective bacteria content is greater than 2×10 8 cfu / ml, at 30 degrees, continuous aerated fermentation for 8 hours, the pH value is about 6, and the effective bacteria content is greater than 0.5×10 8 cfu / ml, the solid content rate is about 5%, a...

Embodiment 3

[0088] Embodiment 3 Continuous treatment of landfill leachate

[0089] First, weigh 200kg of landfill landfill leachate with a disgusting smell, and first settle to remove the precipitated sludge. Next, take 20 kilograms and put it in a 50 kilograms round plastic barrel with a diameter of 38.5cm and a height of 58cm, pass through the aeration pump for aeration, and add the 5‰ of the landfill leachate quality obtained in Example 1 Microbial compound bacterial agent I 0.1kg, its effective bacterial content is greater than 2×10 8 cfu / ml, at 30°C, continuous aeration treatment for 8 hours, the odor disappeared, and a treatment solution with a pH value of about 6 and containing a large number of microorganisms was obtained.

[0090] Then, add new disgusting smell landfill leachate every two hours according to 30% of the initial landfill total mass of the treatment liquid containing a large number of microorganisms, and then the disgusting smell disappears quickly, that is, first a...

The microbial compound bacterial agent of the invention has stable structure, wide functions and no side effects, and is a kind of eco-type microorganism group with high efficiency of enzyme production and easy proliferation. Economical, non-toxic, non-salt.

Description

technical field [0001] The invention belongs to the technical field of microbial treatment of wastewater, and in particular relates to a high-efficiency JM bacteria technology for treating high-salt heavy metal refractory organic wastewater and for antibacterial and deodorizing. Background technique [0002] The treatment of high-salt heavy metals and deep concentrations of refractory organic wastewater has always been a difficult point in this industry. The water quality characteristics of high-salt and high-concentration organic wastewater: First, the concentration of organic matter is high, and COD is generally above 2000mg / L, and some even reach tens of thousands or even hundreds of thousands of mg / L. Relatively speaking, BOD is low, and many wastewater BOD and COD The ratio is less than 0.3; second, the composition is complex, and the organic matter in wastewater containing toxic substances is mostly aromatic compounds and heterocyclic compounds, and also contains sulfi...
