There is no difference between swill and swill, both of which refer to the leftover food waste used in human daily life.

swill refers to the leftovers left by restaurants and families after eating. Urban swill refers to the leftovers discarded by people in restaurants, restaurants, schools, canteens and other places, including leftovers such as vegetables and fish discarded before cooking and the mixture of leftovers discarded by people at home and water.

In the past, the biggest use of swill was to feed pigs, and it also needed to be purchased. Generally, pig farms in the suburbs would reserve swill produced by restaurants in the city, and then ship it to pig farms regularly to feed pigs. At present, the most reasonable and effective way to recycle swill is to collect swill and treat it with microorganisms.

Treatment method of swill

1. Landfill method

In many areas, swill will be sent to landfill together with ordinary garbage for landfill treatment. Landfill is the main way to treat domestic waste in most countries to make it harmless, because swill contains a large number of degradable components, which are unstable and conducive to the recovery and use of landfill sites, and the operation is relatively simple, which is a relatively common treatment method.

2. Feed treatment of swill

The basic principle of feed treatment of swill is to use a large amount of organic matter contained in swill, and after a series of treatments such as crushing, dehydration, fermentation and separation, turn it into treasure and turn it into animal feed with high heat.
