10m3 biogas slurry water-soluble fertilizer production line

detailed explanation

The soluble substances in biogas slurry include organic and ionic substances. Soluble substances are mainly small molecule substances that are decomposed by microorganisms. Due to their simple structure, they can be processed and used for crop nutrition regulation and cultivation, or digested and absorbed by livestock; Ionic substances, such as calcium, phosphorus, potassium, iron, copper, zinc, manganese, molybdenum and other trace elements, molybdenum is a newly added trace element in humic acid water-soluble organic fertilizer NY-1106-2010 standard. These trace elements can penetrate into crop cells and stimulate growth, which is also necessary for crops.

The bioactive substances in biogas slurry, such as amino acids, auxin, cellulase, monosaccharides, unsaturated fatty acids, and certain antibiotics, play an important regulatory role in the entire process of seed germination, plant growth, flowering, and fruiting. They also contribute to crop growth and improve the body's disease resistance. However, at the same time, the biological activity of these carriers makes the biogas slurry unable to have the same stability and shelf life as commodities, and even forms a secondary pollution source, causing economic losses to crop cultivation.

The inorganic ash impurities in biogas slurry affect the sensory, shelf life, and performance of biogas slurry products.

Based on the above, the imbalance of nutrients, insignificant effects, secondary pollution, and poor economic efficiency have led to the almost equivalent effect of biogas slurry as general domestic wastewater, which is not suitable for commercialization requirements and has lost its valuable ecological agricultural resources.

Therefore, the harmless treatment and high-value utilization technology of biogas slurry in large-scale biogas projects, as well as project implementation, is a major issue in achieving large-scale and commercialized supply of biogas slurry. It is the basic guarantee for realizing the industrial production process and low-cost operation of organic agriculture, and an important link to improve the comprehensive performance and economic value of biogas projects and ecological agriculture. Due to the large amount of sludge and slurry generated by large-scale biogas projects, if the sludge and slurry are discarded, it will cause serious environmental and water pollution in the local area. On the basis of the existing development situation, the high-value utilization of biogas residue and slurry resources has solved the problem of pollution in modern agricultural production, promoted the further improvement of the biogas industry, and achieved sustainable development of ecological agriculture.

Features:

Through BEPE ® The biological leaching and biological adsorption functions of the liquid fermentation machine use degradation enzymes to effectively adsorb heavy metal ions dissolved in the biogas slurry. Chelated bioleaching method, with BEPE ® The addition of bio fermentation enzymes increases, and the removal rate of heavy metals in the base manure shows an upward trend. At the same time, its dehydration performance is 143 times higher than that of the original pig manure. After processing, the heavy metal content of the sludge and slurry meets the national standard, providing high-quality raw materials for the next process and improving the reuse value of the base manure. Adopting BEPE ® The finished products produced by the entire production line, with a small amount of residual heavy metal ions entering the soil in a chelated and passivated state, meet national standards after testing.

Principle:

Firstly, precipitate the biogas slurry (solid-liquid ratio, 3:7, 2:8), then pump the slurry into the bacterial growth machine for deodorization and fermentation treatment, BEPE ® Using biological leaching and biological adsorption methods to remove heavy metal ions such as Zn, Cu, As, Mn, Pd, Cr, and Hg from biogas slurry, followed by BEPE treatment ® The biogas slurry processed by the complete set of breeding machines is subjected to solid-liquid separation through a solid-liquid separation device. Then, the separated liquid is pumped into a chelation reaction kettle for biological leaching and humic acid (bioactive bacteria) reaction. Afterwards, the humic acid (bioactive bacteria) reaction liquid is taken into an element chelation reaction kettle and other chemical fertilizer elements are added for chelation reaction. The finished product is packaged.
