Abstract
Description
technical field
[0001] The invention belongs to the technical field of liquid organic fertilizers, and in particular relates to biogas slurry humic acid liquid organic fertilizers and a preparation process thereof. Background technique
[0002] With the rapid development of my country's economy, chemical fertilizers have become an indispensable means of production for agricultural production. Today, chemical fertilizers are the most widely used fertilizers, which are divided into nitrogen fertilizers, phosphorus fertilizers, and potash fertilizers. As the pressure of China's agricultural intensification continues to increase, the input volume and application intensity of chemical fertilizers continue to increase, which directly leads to the continuous aggravation of non-point source pollution caused by chemical fertilizer input, and environmental problems have become increasingly prominent. In agricultural production, our country is facing several major problems. First, the...
Examples
Embodiment 1
[0022] 1. Preparation of biogas slurry: crush wheat, corn, and soybean stalks to less than 10 cm and put the feces of cows, sheep, chickens, ducks, and geese into the fermentation tank, add decomposing agent: water = 1:20 mass ratio, and mix evenly. Turn over and throw once every 3 days to make it fully decomposed and kill harmful bacteria. Add deodorant. After 7 days, the solid and liquid are separated by a solid-liquid separator. The liquid is first transferred to a tank-type anaerobic tank with a temperature of 35-40 °C Ferment for 4 days, then transfer to membrane anaerobic fermentation at a temperature of 30-35°C for 5 days, and obtain biogas slurry after aerobic treatment;
[0023] 2. Bacteria deodorization: first place the biogas slurry with a water content of 60% in the bacteria deodorization tank, the temperature of the bacteria deodorization is 50-60 ° C, and stand for 18 hours;
[0024] 3. Precipitation and filtration: transfer 626 kg of biogas slurry after inoculat...
Embodiment 2
[0028] 1. Preparation of biogas slurry: take sorghum, rice straw, and rice husk straw and crush them to 80 meshes, and put chicken and pig manure, rapeseed oil cake into the fermentation tank, add decomposing agent: water = 1:20 mass ratio, mix evenly, every Turn over once every 2 days to make it fully decomposed and kill harmful bacteria. Add deodorant. After 6 days, the solid and liquid are separated by a solid-liquid separator. The liquid is first transferred to a tank-type anaerobic tank with a temperature of 35-40°C Ferment for 3 days, then transfer to membrane-type anaerobic fermentation at 30-35°C for 3 days, and obtain biogas slurry after aerobic treatment;
[0029] 2. Bacteria deodorization: first place the biogas slurry with a water content of 40% in the bacteria deodorization tank, the temperature of the bacteria deodorization is 40-60 ℃, and stand for 12 hours;
[0030] 3. Precipitation and filtration: transfer 600 kg of biogas slurry after inoculation into a sedim...
Embodiment 3
[0034] 1. Preparation of biogas slurry: take pine shells, peanut shells, sawdust, dried bagasse, edible fungus residues, distiller's grains, sugar residues, vinegar residues, cassava residues, vegetable oil cakes to 80 mesh and chicken, pig, cattle, sheep manure, Put the rapeseed oil cake into the fermentation tank, add it according to the mass ratio of decomposing agent: water = 1:20, mix evenly, turn over and throw once every 2 days, make it fully decomposed and kill harmful bacteria, add deodorant, after 8 days The solid and liquid are separated by a solid-liquid separator. The liquid is first transferred to a tank-type anaerobic fermentation at a temperature of 35-40°C for 5 days, and then transferred to a membrane-type anaerobic fermentation at a temperature of 30-35°C for 4 days. Treated biogas slurry;
[0035] 2. Bacteria deodorization: first place the biogas slurry with a water content of 60% in the bacteria deodorization tank, the temperature of the bacteria deodoriza...
