Description
Technical field
The invention belongs to technical field of domestic garbage treatment, and in particular to a kind of method that domestic garbage resource utilizes and
Equipment.
Background technology
With the iterative method of China's industrialization and urbanization, domestic waste problem is increasingly closed by people
Note.Currently, municipal refuse annual yield in China's is average to produce quantity of refuse about 300kg for each person every year close to 200,000,000 tons, and in recent years
To be increased substantially with 10% speed.Many data are shown, 2/3 is there are about in the large- and-medium size cities in China by rubbish institute " bag
Enclose ", have a strong impact on the quality of life of people.
The target for solving garbage problem is by rubbish volume reduction, decrement, recycling, energy and harmless treatment.At present, lead to
Capable urban garbage disposal disposal technology mainly has burning, landfill, compost, in addition RDF technologies, anaerobic organism natural pond technology
And other treatment technologies also occur and applied to the processing of domestic waste abroad.Actually these technologies are mostly to burn
Burn, landfill, the extending of composting technology, supporting and development.According to《China Statistical Yearbook 2015》, China's garbage harmless in 2014
Total amount is handled up to 16393.7 ten thousand tons, wherein garbage loading embeading amount accounts for the 65.54%% of total amount, burning disposal up to 10744.3 ten thousand tons
Amount accounts for the 32.51% of total amount, garbage compost is in atrophing state up to 5329.9 ten thousand tons.It can be seen that China's domestic waste is main
Or handled by garbage loading embeading with burning mode.Garbage loading embeading not only causes environment to influence, and takes a large amount of soils,
Cause developed regions urban garbage disposal and land resource contradiction sharp.The density of population characterizes soil money to a certain extent
The Tight-binding method in source, East China, Central China and South China's density of population rank first three, and far above other areas, not only illustrate
These regional land resources are in short supply, and show that the Output of Domestic Waste of these regional unit areas is larger, garbage disposal pressure
Power is larger.
China's incineration treatment of garbage is started late, and is limited by economic level, is developed for a long time more slow.Rubbish burns
Burn during being applied in China, because burning method investment is big, occupied fund cycle length；Burning has to the calorific value of rubbish must
Ask, typically cannot be below 5000kJ/kg, limit its application；" dioxin " problem caused by burning process, to work
Skill technology has certain requirement；Operate that lack of standardization, refuse classification is not in place, the flue gas that result in garbage burning factory discharge can not be steady
Surely meet national relevant emission standards, generate a series of problem of environmental pollution, have impact on the normal life of local resident.
