Embodiment 3

[0020] Embodiment 3: a kind of domestication method of degrading sludge, deodorizing flora bacterial classification:

[0021] A. Add 50kg of pure water, 12kg of brown sugar, 150g of potassium dihydrogen phosphate, and 50g of vitamin C into a culture vessel, stir and dissolve to make a culture solution.

[0022] B. Add 5kg of culture medium, 1.2kg of bifidobacteria, 1.0kg of filamentous bacteria, 6kg of lactobacillus, 3kg of yeast, 1.0kg of actinomycetes, 1.0kg of photosynthetic bacteria, and 4.7kg of bacillus into the culture vessel, and stir evenly , Seal the culture vessel, keep the temperature at 25-35°C, and then stir twice a day for half an hour to ventilate. After a week, the test pH is below 4, which means success. If unsuccessful, continue to cultivate until successful.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to the field of sludge treatment by microorganisms. Background technique [0002] Currently, sludge disposal generally adopts landfill or dry incineration. Landfill can easily pollute soil and groundwater, and the cost of incineration is huge and waste gas is emitted. [0003] The activated sludge method is mostly used in the treatment of urban sewage in our country, which has the advantages of low capital investment and good treatment effect. [0004] point, but it has always had one of the biggest drawbacks, that is, a large amount of excess sludge will be generated during operation. Excess sludge usually contains more toxic and harmful substances and unstabilized organic matter. If it is not properly treated and disposed of, it will cause direct or potential pollution to the environment. In the traditional activated sludge method, the degradation of 1kgBOD5 (biochemical OxygenDe...
