  • Anaerobic digestion can obtain three kinds of products, biogas, biogas residue and biogas slurry.
  • Biogas is used to incinerate waste-to-energy.
  • Biogas slurry is used to grow crops and/or vegetables.
  • Biogas residue is used as a culture material for Agaricus bisporus.
  • Traditional fermentation is used. Aerobic fermentation is the main one, the cycle lasts for one month, and the labor intensity is large, the energy loss is much, and the post-seed fermentation treatment before sowing is theoretically: it is an artificial method, which leads to competition with the bisporus.
  • Mushrooms are used to feed cockroaches, worm mounds and biogas slurry for growing crops and/or vegetables.
  • the biogas produced by the anaerobic digestion of weeds, crop straws and livestock manure is used to incinerate waste-to-energy, which is more expensive than the direct combustion of it as a substitute for raw coal.

  • the construction cost of the gas pipeline network is high, and the cost of electricity consumption is naturally high.
  • the calorific value of one cubic meter of biogas is only equivalent to one kilogram of raw coal.
  • the farm is also a large electricity consumer, and the waste heat generated by the power is used to heat up the fermentation raw materials, keep warm or heat the mushroom house, which not only improves the biogas itself.
  • the economic value has alleviated the sharp contradiction of local power shortage. Therefore, the use of biogas for incineration of waste-to-energy generation is higher than that of direct combustion.
  • the invention utilizes livestock manure, urban sewage, weed grass, orange pole and organic matter in municipal solid waste to generate decane (biogas) instead of coal or kerosene to incinerate garbage by anaerobic fermentation; biogas can also directly use piston biogas engine ( Jinan, Shandong, China) direct power generation or use of coal as a substitute for coal, liquefied gas, natural gas; winter slag, winter and autumn, production of Agaricus bisporus, spring pheasant and other precious grass rot fungi; mushroom slag raising, sputum Return organic fertilizer to the field and complete the cycle.

  • This project is a necessary supporting project for using biogas residue as the culture material of Agaricus bisporus and planting forage in biogas slurry. As a culture material for the mushroom
  • the culture of Agaricus bisporus mainly provides nutrients through the decay of manure grass, and the traditional fermentation is "oxygenated". Fermented "mainly, with a period of one month, and labor intensity, energy loss, post-seed fermentation treatment, is a technical treatment program for artificially causing competitive microbial death of bacteria.”

Abstract

La présente invention concerne un procédé de traitement des déchets domestiques urbains. Selon ledit procédé, la matière organique est soumise à une fermentation anaérobie. Le méthane obtenu peut être utilisé dans la combustion pour générer de l'électricité. Les résidus de biogaz obtenus de la fermentation anaérobie peuvent être utilisés comme matériau de culture pour le développement de champignons comestibles. Les résidus des champignons comestibles peuvent être utilisés pour le développement de vers de terre. Indépendamment de la matière organique, l'autre substance des déchets domestiques urbains est incinérée pour générer de l'électricité. La présente invention permet l'utilisation complète des ressources contenues dans les déchets.
