Embodiment 1

[0034] The wool scouring sludge is obtained from the wool scouring treatment pool of the wool spinning mill, the contents of organic matter, total nitrogen, total phosphorus, and total potassium are 65%, 8%, 4%, and 3% respectively, and the total mass is 100 kg. The implantation of microorganisms The total amount is 10% of the sludge mass, and it is fermented in a self-made cement cuboid fermentation tank. Put 100 kg of the obtained sludge into the fermentation tank, and then implant microorganisms for fermentation. Bacteria (including Bacillus-subtilis, Pseudomonas aeruginosa, Bacillagjnosus), fungi (including Aspergillus niger, Penicillium simplicissim), put Nematodes (Streptomyces badius) = 20:2:1, Bacillus subtilis: Pseudomonas aeruginosa: Bacillus colloidus = 2:1:0.4, Aspergillus niger: Penicillium simpleum = 2: 1; Fermentation time = 21 days, fermentation temperature: 48°C, pH = 7.5; organic matter, N, P and K contents after fermentation: 60%, 9%, 4.5%, 3.5%.

Embodiment 2

[0036] The wool scouring sludge is obtained from the wool scouring treatment pool of the wool spinning factory. The contents of organic matter, total nitrogen, total phosphorus, and total potassium are 65%, 8%, 4%, and 3% respectively, and the total mass is 100 kg. The amount is 10% of the mass of the sludge, and it is fermented in a self-made cement cuboid fermentation tank. Put 100 kg of the obtained sludge into the fermentation tank, and then implant microorganisms for fermentation. Bacteria (including Bacillus subtilis, Pseudomonas aeruginosa, Bacillagjnosus), fungi (including Aspergillus niger, Penicillium simplicissim), Actinomycetes (including Streptomyces badius) = 20:5:3, Bacillus subtilis: Pseudomonas aeruginosa: Bacillus colloidus = 3:1:0.5, Aspergillus niger: Penicillium simpleum = 5 : 3; fermentation time=18 days, temperature: 52° C., pH=8.0, organic matter after fermentation, N, P and K contents: 54%, 9.7%, 5%, 4%.

Embodiment 3

[0038] The scouring sludge is obtained from the wool scouring treatment pool of the wool spinning mill, the contents of organic matter, total nitrogen, total phosphorus, and total potassium are 60%, 8%, 4.2%, and 3% respectively, and the total mass is 100 kg. The implantation of microorganisms The total amount is 10% of the sludge mass, and it is fermented in a self-made cement cuboid fermentation tank. Put 100 kg of the obtained sludge into the fermentation tank, and then implant microorganisms for fermentation. Bacteria (including Bacillus subtilis, Pseudomonas aeruginosa, Bacillagjnosus), fungi (including Aspergillus niger, Penicillium simplicissim), actinomycetes Bacteria (including Streptomyces badius) = 20:4:3, Bacillus subtilis: Pseudomonas aeruginosa: Bacillus colloidus = 4:3:1, Aspergillus niger: Penicillium simpleum = 2:1 ; Fermentation time = 28 days, temperature: 54°C, pH = 8.0; organic matter, N, P and K contents after fermentation: 44%, 11%, 5.5%, 4.3%.

Abstract

The invention relates to a method for preparing compost by washing wool junk microbial fermentation. Microorganism accounting for 10 percent of the total mass of silt is implanted in the washing wool silt and fermented for 15-30 days at the temperature of 45-65 DEG C. The microorganisms are the composite of bacteria, fungi and actinomycetes, and the number ratio of the bacteria, the fungi and the actinomycetes is 10-30:0.5-2.5:0-1.5. The bacteria are bacillus subtilis, Pseudomonas aeruginosa and Bacillus mucilaginosus with the number ratio of 1-5:0.5-3:0.3-1.5; and the fungi are Aspergillus niger and Penicillium simplicissimum with the number ratio of 1-3:0.5-1.5. The compost produced by fermentation contains 30-80% of organic matter, 3-15% of total nitrogen, 2-10% of total phosphorus and 1-7% of total potassium.

Description

technical field [0001] The invention belongs to the technical field of waste water and sludge treatment, in particular to the treatment of animal hair washing waste water; meanwhile, it relates to a method for fermenting with microorganisms to obtain fertilizer. Background technique [0002] Wool washing wastewater is a high-concentration organic wastewater, and its main components include lanolin, detergent, sheep sweat, sheep manure, grass clippings, short hair and sediment. The lanolin content of wool washing sewage is 5-20g / L, and the COD value is generally 4×10 4 ~6×10 4 Between mg / L, up to 10×10 4 mg / L, the lanolin content is high, and the pollution is extremely serious [1] . At present, the washing of raw wool is mainly based on emulsified aqueous solution at home and abroad. The temperature of the aqueous solution for washing wool is generally between 50 and 70°C. After washing, the wool needs to be dried, which requires heat energy (steam) to complete. Therefor...
