Embodiment 1

[0028] A 100-head pig farm in Zhengzhou City produces about 2000kg of feces every day. Two septic tanks have been built in the farm area, and the size of each tank is 5000x3000x2000mm. We installed a liquid level controller in the pool, the height limit is 15000mm, and the actual volume of a single pool is 22.5m 3 , Change one of the two septic tanks into a biochemical hydrolysis tank, and install air ducts and wind jets in the tanks. Next to the biochemical hydrolysis tank, we installed a set of livestock and poultry manure bio-fertilization device with an overall size of 6000x2500x1500mm. In the device, we laid 1 meter thick crushed corn straw and wheat straw at a ratio of 1:1, with a total volume of about 15m 3 . After the fan installed on the livestock and poultry manure biological fertilizer plant is started, the manure in the two ponds is fully stirred through the air duct and the wind jet, and the measured solid-liquid ratio is 1:52. According to the ratio of crushed ...

Embodiment 2

[0033] In a dairy farm with 100 cows in the southern suburb of Jiyuan City, the daily manure production is about 3000kg, and there are four 4000x3000x2000mm manure collection tanks connected together. We selected two pools to transform into a fecal storage pool and a biochemical hydrolysis pool, and installed liquid level controllers in the pools respectively, with a height limit of 15000mm and an actual volume of 18m 3 , A set of 6000x2500x1500mm livestock and poultry manure biological fertilizer device was installed next to the biochemical hydrolysis tank, and 0.8 meters thick crushed crop straw was laid in the device, with a total amount of about 12m 3 . Start the PLC controller, fully stir the manure in the manure storage tank and biochemical hydrolysis tank according to the set program, and the solid-liquid ratio test in the laboratory is 1:4.8. According to the ratio of 6:4 of crushed crop straw and manure, the submersible sewage pump is used to extract 8 m of waste wat...

Abstract

The invention provides a method for making a biological fertilizer by utilizing livestock and poultry waste. Feces (excrement) produced in a livestock and poultry farm area is delivered to a feces storage tank, a wind driven jet flow stirrer breaks feces into thin paste, the thin paste is fed into a biochemical hydrolysis tank through a water passing port formed in a partition wall for the feces storage tank and a biochemical hydrolysis tank for biochemical pretreatment, then a submersible sewage pump delivers the feces to a movable feces sprinkler through a pipe and is uniformly sprayed onto smashed crop straws in a device for making the biological fertilizer by utilizing the livestock and poultry waste, a liftable movable turning and throwing machine arranged on the b device for making the biological fertilizer by utilizing the livestock and poultry waste uniformly turns and throws the feces, a fungicide and the smashed crop straws, mixed fermentation is performed to make a biological organic fertilizer, percolate produced in the fermentation process flows back to the biochemical hydrolysis tank through a percolate draining pipe for reutilization, and a finished product fertilizer is discharged out of a feeding-discharging port. The method is novel, unique, scientific, reasonable and environment-friendly, the raw materials are rich and easy to produce, the effect is good, energy is saved, and economic and social benefits are huge.

Description

technical field [0001] The invention relates to fertilizer, in particular to a method for biologically producing fertilizer from livestock and poultry manure (feces) and crop stalks. The livestock and poultry manure refers to the manure and flushing sewage produced by livestock and poultry breeding. Background technique [0002] According to the data of the National Bureau of Statistics at the end of 2015, the annual pig stock in my country is about 700 million, and each pig produces about 15kg of feces every day, which is about 10.5 million tons per day nationwide, and about 3.8 billion tons for the whole year. The content of ammonia nitrogen in feces and urine excreted by livestock and poultry is 800mg / kg-1200mg / kg (calculated as N), and the content of phosphorus is 90mg / kg-120mg / kg (calculated as P); COD (chemical Oxygen demand) content is 5000mg / L, ammonia nitrogen content is 1000mg / L~1200mg / L, phosphorus content is 100-120mg / L, and a large number of antibiotic drug res...
