Problems solved by technology

[0002] At present, there are two ways to recycle food waste (also known as kitchen leftovers) in my country. One of them is to regenerate food waste into feed protein powder, oil, and fermented feed. The disadvantages are large energy consumption and waste water treatment. The other is to regenerate organic fertilizers. The disadvantages are high investment, difficult product sales, and poor economic benefits. Therefore, the above two treatment methods have certain resistance to the resource utilization and large-scale recycling of food waste.

Abstract

The invention relates to a method for treating kitchen waste regenerate grease, biological natural gas, fertilizer and forge, wherein it comprises forty eight devices, to form kitchen waste pretreatment section, regenerate grease section, regenerate biological natural gas section, regenerate fertilizer section, regenerate forge section, and sewage treatment section. The invention is characterized in that: the pretreatment section cleans the harmful foreign materials of kitchen waste; the regenerate grease section separates the grease of mixture discharged by pretreatment section; the regenerate biological natural gas section ferments the mixture liquid of pretreatment section and regenerate grease section to generate marsh gas, to be purified to obtain biological natural gas; then the regenerate fertilizer section and regenerate forge section treats the natural gas into liquid fertilizer and protein forge; the sewage treatment section discharges the sewage.

Description

technical field [0001] The invention relates to a process for resource recycling of kitchen waste, in particular to a six-stage process for recycling kitchen waste oil, biological natural gas, medicinal fertilizer and feed. Background technique [0002] At present, there are two ways to recycle food waste (also known as kitchen leftovers) in my country. One of them is to regenerate food waste into feed protein powder, oil, and fermented feed. The disadvantages are large energy consumption and waste water treatment. The other is to regenerate organic fertilizers. The disadvantages are high investment, difficult product sales, and poor economic benefits. Therefore, the above two treatment methods have certain resistance to the resource utilization and large-scale recycling of food waste. Contents of the invention [0003] The purpose of the present invention is to regenerate the kitchen waste into oil, biological natural gas, medicinal fertilizer, Feed and oil are the raw ma...
