Example Embodiment
[0050] Example 1. Preparation of inoculum
[0051] Bacillus subtilis, lactic acid bacteria, yeast, Bacillus megaterium, Bacillus mohewei, Bacillus pumilus are proportioned according to 4-8:3-7:2-7:4-5:9-11:10-20, details as follows:
[0052] Cultivate Bacillus subtilis alone for 3-5 days under sterile conditions at 37°C until the number of cells per milliliter reaches 10 9 ;
[0053] Cultivate lactic acid bacteria alone for 2-3 days under sterile conditions at 37°C, until the number of cells per milliliter reaches 10 9 ;
[0054] Incubate yeast alone for 2-3 days under sterile conditions at 37°C, until the number of cells per milliliter reaches 10 9 ;
[0055] Cultivate Bacillus megaterium alone for 3-4 days under sterile conditions at 37°C until the number of cells per milliliter reaches 10 9 ;
[0056] Cultivate Bacillus mohewei individually for 3-5 days under sterile conditions at 37°C, until the number of cells per milliliter reaches 10 9 ;
[0057] Cultivate Baci...
Example Embodiment
[0065] Example 2
[0066] 1. Organic waste treatment
[0067] a) The municipal solid waste organic matter after classification and collection enters the pulverization process, and pulverizes some substances with large particle size. Generally, after two stages of pulverization, the first stage is pulverized to a particle size of 3-5cm; the second stage pulverization For the particle size of 1-1.5cm;
[0068] b) Put the crushed organic waste into the fermentation box, add zeolite or bran and mix well. The main function of zeolite or bran is to provide a space between materials to promote air flow between materials;
[0069] c) The body starts to automatically stir, stirring once every 10 minutes, stirring for 10 minutes each time, heating the material while stirring, adding 1 liter of bacterial agent per ton of organic waste and supplying oxygen to carry out aerobic fermentation; control the fermentation temperature to be 66℃; the method of adding the bacterial agent for 3 se...
Example Embodiment
[0085] Example 3
[0086] The steps are the same as in Example 2, except that:
[0087] 1. Organic waste treatment
[0088] The fermentation temperature was controlled to be 55°C, and the mixture was stirred at intervals of 15 minutes for 10 minutes, and 0.3 liter of bacterial agent was added per ton of organic waste, and the organic liquid fertilizer was obtained after 48 hours of fermentation.
[0089] 2. Sludge pretreatment
[0090] Put 3 kg of quicklime per ton of sludge, put zeolite and bran with a weight of 30% of the dewatered sludge in the first-stage mixing tank, and put a deodorant powder with a weight of 10% of the sludge in the mixing process.
[0091] 3. Mixing of two materials
[0092] Mix the organic liquid fertilizer and sludge in a mass ratio of 0.2:1, adjust the pH value to 7 after mixing, and use bran or straw to adjust the moisture content of the material to 40%, and the input ratio is 1 ton of mixed material input 0.6 tons of bran or 0.4 tons of comminut...
