Embodiment 1

[0038] Embodiment 1, as Fig. 1 is the process route schematic diagram of the present invention method, shows inoculation bin 1 in the figure, two turnover bins 2,5, three progressive bins 3,4,6, discharge bin 7; 2. Hot water coil heaters 8, 9, 10, etc. are installed at the bottom of each bin for heating when moving materials from each bin. The production cycle is 24 hours. Before starting work, according to the process of the present invention, the inoculation bin 1, the first progressive bin 3, the second progressive bin 4, and the third progressive bin 6 are gradually filled with prescribed materials; the turnover bins 2 and 5 are empty of. In the inoculation bin 1, the masterbatch (the anaerobic activated sludge accumulated in the sewage treatment plant is used in this embodiment) is loaded at one time as the strain, and the masterbatch is considered by 5 times the weight of the raw material. After the system runs, only Just add the raw material, no need to add any foreig...

Embodiment 2

[0046] Embodiment 2 is another kind of process (reverse delivery) route of the inventive method, basically identical with embodiment 1, difference is: in described step (3) discharging, the material in the discharge bin 7 is sent out When, retain part of the material (mature bacterial classification) in the described discharge bin 7, send out the material other than the reserved material for separation, and send the described reserved material back into the described inoculation bin 1; Circulate the supplementary masterbatch returned inside to ensure that there is a sufficient number of bacteria in the inoculation bin 1;

[0047] For example, taking the production of 30 tons of organic fertilizer per day as an example, the masterbatch is considered to be 4 times the weight of the raw material. Step (1) When charging, keep 114 tons of masterbatch in the inoculation bin 1, add 6 tons of part of the material returned from the discharge bin 7, then the total amount of masterbatch ...

Abstract

Production of organic fertilizer is carried out by charging, extracting materials from bins, delivering them into vacant bin, re-extracting materials from vacant bin, returning them to original bins, heating, discharging and separating. It's cheap, large scaled and has no environmental pollution. It utilizes animal and urban feces as raw material to produce by-product methane as agricultural fuel.

Description

technical field [0001] The invention relates to a method for preparing fertilizer, in particular to a method for preparing organic fertilizer. Background technique [0002] The development of rural breeding industry is a means for Chinese farmers to get rich. In rural China, modern large-scale breeding has developed rapidly, bringing benefits to farmers. But at the same time of development, it has also brought a large amount of livestock and poultry manure that is difficult to deal with. For example, a county in Shandong Province produces 7,000 tons of livestock and poultry manure every day, causing serious air and surface water pollution. In a place where pigs are concentrated in Hunan, the water source has been polluted by livestock and poultry feces, which has reached 10 meters underground, seriously affecting life. At present, the annual production of livestock and poultry manure in my country has reached 1.9 billion tons, which is more than twice the discharge of ind...
