Concentration sewage enters sewage network, so that script is silted serious sewage network up and more can't bear the heavy load, it is therefore desirable to can effectively prevent
The measure that sewage network silts up.A large amount of domestic waste and food garbage cause people's living environment and urban development
How huge pressure and harm realize that the processing of innoxious domestic waste, minimizing and recycling has become research
Focus.
At present countries in the world processing domestic waste method usually have the methods of composting method, landfill method and burning method into
Row processing, and for food garbage without good processing method.And most of implementation landfill in the house refuse in China,
It is handled with composting method at least partially through burning, the part in food garbage can be admitted to fermentation vat for producing methane, also
Part food garbage can be poured into directly in sewer pipe.
