Embodiment 1

[0016] A process for the harmless treatment of domestic waste, mainly comprising the following steps,

[0017] 1) Crushing, crushing the garbage to reach a certain particle size range;

[0018] 2) Decomposition, put the crushed garbage into the fermentation tank, and add microorganisms to make the organic matter in the garbage ferment and decompose;

[0019] 3) pressure filtration, the fermented product is filtered through a filter press, wherein a filter membrane is used to separate solid substances from liquid substances;

[0020] 4) Disinfection, limestone disinfects solid matter;

[0021] 5) Filtration, using activated carbon to filter liquid substances;

[0022] Through the above steps, the garbage can be effectively disposed of.

Embodiment 2

[0024] A process for the harmless treatment of domestic waste, mainly comprising the following steps,

Abstract

The invention discloses a harmless treatment method of household garbage, belongs to the field of environmental protection and aims to achieve the purpose of efficiently treating the garbage. According to the technical scheme, the harmless treatment method of household garbage mainly comprises the steps of crushing, decomposing, filter pressing, disinfecting and filtering. Through the garbage harmless treatment method of household garbage, the garbage can be efficiently treated; high polymer materials which cannot be fermented and decomposed are efficiently separated from metal materials, so that the high polymer materials can be reused; the treated water is free of impurities and free of peculiar smell, can be used as special water for flushing toilets and can also be used as special water for watering flowers and trees; solid materials mainly comprise some household garbage and are rich in proteins and celluloses; the treated solid materials can be used as excellent organic fertilizers, can be used as excellent fertilizers of flowers and trees, and can also be popularized and applied to farmland. The garbage treatment method is scientific, reasonable and simple, and is high in treatment efficiency, high in comprehensive benefit and high in utilization rate.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a process for harmless treatment of domestic garbage. Background technique [0002] There are a lot of domestic garbage produced daily, which has become an extremely difficult urban disease. At present, high-temperature combustion and local burial are mainly used. The former is prone to produce dioxins, while the latter occupies a large amount of land and is likely to pollute groundwater. Nowadays, the classified treatment of garbage is vigorously advocated, but the results are minimal, people still go their own way, and it is very difficult to dispose of garbage Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a harmless treatment process for domestic garbage, so as to achieve the purpose of effectively treating garbage. [0004] In order to solve the above-mentioned technical problems, the techni...
