Embodiment
[0015] Embodiment: a kind of domestic garbage biological drying and disinfection process, such as figure 1 As shown, the biological drying and disinfection process of domestic waste is to sort, crush and hydraulically dehydrate domestic waste, and then send it to a biological drying room (see another patent application named "a biological drying and disinfection room" for details) for drying the method of disinfection;
[0016] Specifically include the following steps:
[0017] 1) Garbage sorting: Sorting inorganic substances such as metal, glass, and stones in the original domestic garbage, recycling and reusing the inorganic substances, and retaining the organic substances in the domestic garbage;
[0018] 2) Garbage shredding: Put the remaining organic domestic waste after sorting and removing the inorganic matter into the shredder, so that the maximum particle size of the organic domestic waste is below 8cm;
[0019] 3) Hydraulic dehydration: Put the crushed organic dome...

The invention discloses a household garbage biological drying and disinfection process. The household garbage biological drying and disinfection process is a method that original household garbage is subjected to sorting, smashing and hydraulic dehydration and then fed into a biological drying chamber to be dried and disinfected. The household garbage biological drying and disinfection process comprises the steps of garbage sorting, garbage smashing, hydraulic dehydration, biological drying and the like. According to the household garbage biological drying and disinfection process, active bacteria are added for drying, and 15% of moisture can be removed at a time, so that the drying cost is reduced, the garbage drying time is shortened, and the garbage heat value is increased; the power generation quantity of the garbage can be increased if the garbage is used for power generation; and most harmful bacteria can be directly killed.
Description
technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to a biological drying and disinfection process for domestic waste. Background technique [0002] With the rapid development of my country's economy, the output of domestic garbage in my country is increasing day by day, and the treatment and disposal of garbage has become a problem that must be solved in large and medium-sized cities in my country; at present, the annual output of urban garbage in my country is about 150 million tons, and it is increasing year by year It is growing; how to realize the "three modernizations" of municipal solid waste harmlessness, reduction and resource utilization has become the focus of research. Sorting and selecting combustible parts of domestic waste to make fuel rods or pyrolysis and gasification to obtain combustible gas, using the heat energy obtained by burning fuel rods or combustible gas for power generation, brick burning ...
