Description
Technical field
The invention belongs to environmental treatment equipment technical fields, belong to pollutant storage, transfer, filtering, extraction systems technology
A kind of field, and in particular to solid waste extraction system and method.
Background technique
The development of society, people's the accelerating rhythm of life, more and more wastes generate, especially some solid wastes
Object, substantial amounts are seriously polluted.Different wastes has different processing modes.Current main processing mode has: filling out
It buries, biological process for preparing fertilizer and burning etc..Burying method is mature, but early investment is big, wastes large amount of land resources；Biological process for preparing fertilizer
It takes up a large area, complex process, strong to temperature dependency, processing speed is slow, has dense odor contamination, strain easily to change；
Many incinerators have been built now for handling waste, and there there are many places also to generate in newly-built incinerator, burning to be a large amount of
Toxic gas causes potential or real harm to environment.In current processing mode, pollutant bring environment is dirty
The dye duration is extremely long, and there are physiological-toxicities and neurotoxicity.Solid waste meets water leaching in stacking or disposal process,
Make noxious material Transport And Transformation therein, into soil.When the amount of the noxious material of entrance is more than the threshold of relevant laws and regulations defined
When value, which has Leaching.The leaching characteristic identification of solid waste is the judgment basis of danger wastes,
It is also the important technical links of solid waste management, processing technique exploitation and processing.
Current solid waste Leaching leaching method is that " solid is useless for People's Republic of China's environmental protection professional standard
Gurry Leaching method sulfonitric method " (HJ/T299-2007) and " solid waste Leaching method acetate buffer sepage
Method " method as defined in (HJ/T300-2007), the toxicity for being widely used in environmental protection, solidification disposal of waste etc. and solid waste identifies,
The relevant industries of research, processing, disposition, are also applied for the pilot production and scientific research of the industries such as medicine, chemical industry, teaching.Gu
Body waste Leaching leaching method mainly has sulfonitric method, and leaching program substantially is leaching with nitric acid, sulfuric acid mixed solution
