How to Deal with Pig Manure in Large Pig Farms?
The treatment of pig manure in large pig farms is a major problem in the breeding industry. Long-term storage will not only attract mosquitoes and flies, but also cause pollution to the surrounding environment and groundwater sources. “Pig manure may be a problem in other farms, but for us, pig manure is a treasure! Nowadays, organic manure of pig manure has become a new profit point for the pig farm, with millions of profits a year, which is truly realized.” Pig manure is fishing for gold”. According to an organic fertilizer manufacturer that specializes in processing pig excrement, 10 to 20 tons of pig manure are transported here every day. It is not difficult to find that the organic fertilizer plant has a fermentation tank 2 meters above the ground. , Rice bran, straw and other fermented materials are piled underneath. The principle is to fully decompose and transform the organic matter of pig manure through the decomposition and fermentation of a variety of microorganisms.
“Pig manure is added with biological inoculants in proportion, the machine is evenly stirred and then fermented, and then processed through processes such as crushing, screening, and air drying. The animal manure is completely deodorized, and the waste is turned into valuable organic fertilizer. “The staff of the organic fertilizer factory said. All the pig manure from the pig farm can be transported here to be processed into organic fertilizer and become bio-organic fertilizer. For this kind of pig manure organic fertilizer, compared with chemical fertilizer, it is not only “good quality and low price”, but also beneficial to environmental protection. Pig manure organic fertilizer does not contain any chemical components, so that the dried product contains nitrogen, phosphorus, potassium, organic matter, amino acids, protein and other ingredients.
Pre-fermentation part: It is necessary to build a fermentation tank with a width of 3 meters x a length of 50 meters (more than 200 tons of raw materials can be fermented), or one machine with multiple tanks. Then the raw materials (dung, biogas residue, straw) are piled in the fermentation tank, and 1 kg of decomposing agent is mixed with 20 kg of water, and mixed in the raw material pile. 1 kg of decomposing agent can ferment 1 ton of raw materials, and mix them according to the comparison of raw materials. The fermentation cycle is 7-10 days at a temperature of about 30°C, and the fermentation cycle is 7-10 days.
The organic fertilizer raw materials are fermented and decomposed, crushed by a semi-wet material pulverizer, and sieved through a drum screen. The coarse material is sieved out and then fermented, the fine material can be granulated, the appearance of the granules is more beautiful, and the granulation rate is higher.
The fermented materials (moisture content at 35%) are blended by a mixer, and then passed through an organic fertilizer granulator, and then dried through an organic fertilizer dryer, cooled by a cooler, and screened by a drum sieving machine. Unqualified products Back to the mixer, qualified products can be coated with calcium, magnesium, sulfur and other trace elements through the powder coating machine. This is pig manure organic fertilizer.
