The problem of high cost and immature technology always exists in the mass harmless treatment of livestock and poultry manure pollution and waste straw generated in the process of agricultural production. In October 2019, the project of combined household gas supply and organic fertilizer recycling in zunhua meiduo group, which was contracted by yingherui environment, adopted new technology and new technology to solve the problem of harmless treatment of agricultural production waste in large quantities, and successfully put it into operation, realizing the transformation of waste into wealth.
With a total investment of 560 million yuan, the project can realize the resource utilization and harmless treatment of livestock and poultry manure pollution and waste straw, maximize the recovery of energy, and greatly reduce rural environmental pollution. It is expected to reduce 550,000 tons of carbon dioxide and 4,800 tons of hydrogen sulfide every year. The biogas produced by the project can also be used in many fields.
In addition to the production of biogas, the remaining residue of biogas digester, biogas slurry can be used as organic fertilizer, which greatly improves the industrial chain, and also enhance the added value of the product. Mektor group livestock and poultry manure straw methane combined household gas supply and organic fertilizer recycling project is the only determined by the Ministry of Agriculture and Rural Affairs of hebei province livestock and poultry manure pollution whole county to promote the leading backbone project, is currently the largest, tangshan only large livestock and poultry manure pollution, straw treatment project.
