The relevant person in charge of the plant said: "we mainly deal with food waste, kitchen waste, etc., adopting the process of pretreatment + combined anaerobic digestion + comprehensive utilization. At present, the contracted treatment capacity for Guangzhou's six central districts is 400 tons of catering waste, 600 tons of kitchen waste, and 2040 tons of other kinds of biomass waste, which is the largest urban organic waste treatment project in the world. " How to solve the problem of many impurities and complex ingredients in kitchen waste? The relevant person in charge of the factory said: "After the kitchen waste is transported to us, we will remove the impurities first, which is the most difficult part in the food waste treatment process. The way we adopt is to carry out high-pressure pressing separation. The purpose is to achieve the dry and wet separation of kitchen waste, and to obtain wet components (organic matter) and dry components (impurities). " The plant area adopts the automatic ultra-high pressure waste pressing device, and the separated waste can be transformed into "treasure". Among them, the wet component is used for anaerobic fermentation, and the biogas generated in the anaerobic fermentation process can be converted into electric energy; after the biogas residue is dehydrated, it can be processed into the raw material of biological fertilizer. Dry components are used for incineration power generation.
