Description
Technical field
The present invention relates to the processing technology fields of kitchen garbage, the biomass waste material that urban landscaping generates and sludge.
Background technique
By the end of the year 2014, national the planned city, county (hereinafter referred to as cities and towns are free of other organic towns) add up to build up sewage
Treatment plant 3717,1.57 billion cubic meters of sewage treatment capacity/day, newly-increased about 800 ten thousand steres/day compared with 2013.
National the planned city builds up sewage treatment plant 2107 of putting into operation, forms 1.29 hundred million cubes of sewage treatment capacity
Rice/day, newly-increased about 600 ten thousand steres/day compared with 2013.
With increasing substantially for sewage treatment capacity, the yield of sludge is also being dramatically increased.According to statistics, by
The end of the year 2014, the yield of national wet mud (moisture content 80%) are 1,000,000 ton/days.Most sludge is merely by belt
The machinery simple dehydration such as filter press or centrifuge is to 80%, and just outward transport disposition, be easy to cause secondary pollution.With economic hair
Exhibition, population are constantly migrated to big city, and kitchen garbage also increases significantly.Currently, in national policy level, although requirement pair
Kitchen garbage is classified, but is lacked and effectively handled disposal options, fails that kitchen garbage is effectively carried out resource again
It utilizes.
In addition, can also generate a large amount of deadwood, tree during afforestation as city size also expands constantly
Leaf, withered grass, stalk, timber, sawdust etc., due to a lack of effective processing mode, major part is transported to together with house refuse
Landfill yard landfill, causes a large amount of wasting of resources.
Therefore, how these urban waste to be stabilized, minimizing, innoxious and recycling treatment, is become
The new problem that each place is faced.
