3. Incineration method: the available resources are burned, the harmful waste gas generated by combustion is expensive to purify, and the ash residue will also bring secondary pollution
The above three methods all deal with the garbage directly without pre-selection, so their disadvantages are obvious

Embodiment 1

[0024] A method for disposing and reusing human domestic waste, comprising the following steps:

[0025] 1) The 1,000 kg bagged garbage is transported to the bag breaking machine by the chain plate machine for bag breaking treatment, and then screened through a bouncing sieve with a screen mesh of 80mm, and the garbage is screened into light materials on the sieve and heavy materials on the sieve Substances and undersieves, including 300 kg of undersieves, 300 kg of heavy materials on the sieve, and 400 kg of light materials on the sieve.

[0026] 2) After secondary crushing and dehydration of the light material on the screen, the resulting product is made into RDF; the heavy material on the screen is first sorted into 20 kg of large metal parts, 50 kg of large fruit and vegetable skins and masonry After the material after the magnetic separator is crushed for the second time, squeezed and dehydrated for the second time, the resulting product is made into RDF; the underscreen ...

Embodiment 2

[0029] A method for disposing and reusing human domestic waste, comprising the following steps:

[0030] 1) The 1,000 kg bagged garbage is transported to the bag breaking machine by the chain plate machine for bag breaking treatment, and then screened through a bouncing sieve with a screen mesh of 80mm, and the garbage is screened into light materials on the sieve and heavy materials on the sieve Substances and undersieves, including 350 kg of undersieves, 280 kg of heavy materials on the sieve, and 370 kg of light materials on the sieve.

[0031] 2) After secondary crushing and dehydration of the light materials on the sieve, the resultant is made into RDF; the heavy materials on the sieve are first sorted into 25 kg of large metal parts, 48 ​​kg of large fruit and vegetable skins and masonry After the material after the magnetic separator is crushed for the second time, squeezed and dehydrated for the second time, the resulting product is made into RDF; the underscreen is sq...

Embodiment 3

[0034] A method for disposing and reusing human domestic waste, comprising the following steps:

[0035] 1) The 1,000 kg bagged garbage is transported to the bag breaking machine by the chain plate machine for bag breaking treatment, and then screened through a bouncing sieve with a screen mesh of 80mm, and the garbage is screened into light materials on the sieve and heavy materials on the sieve Substances and undersieves, including 400 kg of undersieves, 250 kg of heavy materials on the sieve, and 350 kg of light materials on the sieve.

[0036]2) After secondary crushing and dehydration of the light material on the screen, the resulting product is made into RDF; the heavy material on the screen is first sorted into 28 kg of large metal parts, 46 kg of large fruit and vegetable skins and masonry block 25 kg, and transport the residue to the magnetic separator for sorting. After the material after the magnetic separator is subjected to secondary crushing and secondary pressin...

Abstract

The invention provides a human household garbage disposition and recycling method. The human household garbage disposition and recycling method comprises following steps: 1) human household garbage is sieved using a bouncing sieve so as to divide the human household garbage into an oversize light material, an oversize heavy material, and an undersize material; 2) the oversize light material is subjected to secondary crushing and secondary squeezing and dewatering, an obtained product is subjected to refuse derived fuel (RDF) treatment; the oversize heavy material is subjected to sorting firstly, an obtained residue is subjected to sorting using a magnet separator, and an obtained material is subjected to RDF treatment; the undersize material is subjected to squeezing and dewatering, an obtained solid material is subjected to secondary sorting using a secondary separating sieve, an obtained secondary oversize product is subjected to sieving using the magnet separator, an obtained nonmetallic substance is subjected to secondary crushing and secondary squeezing and dewatering, and an obtained processed product is subjected to RDF treatment. According to the human household garbage disposition and recycling method, fermentation chamber ponds and fermentation equipment are not needed; the human household garbage disposition and recycling method is friendly to the environment, is very suitable for city building, and is relatively in cost, so that the human household garbage disposition and recycling method is especially suitable for small and medium garbage disposal plants in medium and small towns.

Description

technical field [0001] The invention relates to the technical field of waste resource recycling, in particular to a method for disposing and reusing human domestic waste. Background technique [0002] With the continuous improvement of people's living standards, the types and quantities of garbage are increasing day by day, and the treatment methods for garbage are also constantly developing. Especially, the recycling and reuse of garbage has become the main trend of the development of garbage treatment. The development of the practicability and popularity of the methods and methods is even more urgent. [0003] In order to realize the recycling of garbage, the first thing to do is to classify the garbage. Although in our country, people are currently advocating that people are strengthening the classification of discarded garbage, but in real life, people still seldom or do not have the habit of consciously following the signs of garbage bins. Classification, so it is stil...
