Method 1: Crushing and direct drainage

Due to the limited kitchen space, on-site reduction treatment is the basic foothold of swill waste treatment. At present, many countries have adopted the method of disposing swill waste treatment device in the kitchen, and discharging the crushed swill waste into the municipal sewer network, mixing it with water and then putting it into the municipal sewage treatment system for harmless treatment, so as to achieve the purpose of harmlessness.

Method 2: Landfill

In many areas, swill waste is sent to landfills for landfill treatment together with ordinary garbage. Landfill is the main treatment method for harmless treatment of domestic waste in most countries. Because swill waste contains a large number of degradable components, its stability time is short, which is beneficial to the recovery and use of landfill sites, and its operation is simple, so it is widely used.

method 3: feed treatment

the principle of feed treatment of swill waste is to use a large amount of organic matter contained in swill waste, and after crushing, dehydration, fermentation and soft-hard separation, the waste will be transformed into high-calorie animal feed, turning waste into treasure.

method 4: energy treatment

mainly includes incineration, thermal decomposition, hydrogen production by fermentation, etc. Incineration method has a high efficiency in treating kitchen waste, and finally produces about 5% residue which is convenient for disposal. Incineration is carried out in a special incinerator, and the generated heat energy can be converted into steam or electric energy, thus realizing the recycling of energy.

Precautions for feeding swill to pigs:

1. Swill is easy to rot, especially in summer, so it should be transported in time.

2. It is best to collect swill separately. Never mix soiled and rotten vegetable leaves in the swill, so as not to reduce the quality of the swill.

3. Swill water must be boiled and disinfected before it can be fed to pigs, which can kill pathogenic microorganisms and prevent the spread and spread of infectious diseases caused by raw drowning.

4. There will be a layer of floating oil on the surface of the slightly cooled swill, which must be skimmed off, otherwise the pigs will be prone to diarrhea after eating.
