Description
Technical field
The present invention relates to a kind of technical field of waste processing, the dangerous solid wastes recycling processing of especially a kind of organic matter
Method.
Background technology
It is essential in life to will appear solid waste, and the solid waste that we often say is in addition to house refuse, kitchen
Rubbish etc. is outer, generally further includes electron wastes, Biohazard Waste etc., and different solid waste substance treating methods is also different,
It is producing methane through anaerobic fermentation etc. that for example electron wastes, which are usually recycling, kitchen garbage popular at present,.Consider
To general public's degree of attentiveness, what I tentatively guessed that you may ask is house refuse.
If house refuse, four classes can also be roughly divided into according to processing method, to fill, burning, compost and synthesis
Processing, each technique respectively have its advantage, also have its deficiency, in actual process, need to be selected according to actual conditions.Such as
Landfill is longer in China's development time, and technology is also relatively simple, and cost of investment is relatively low, these are all its advantages, but insufficient also very bright
Aobvious, if floor space is larger, especially in the popular city of soil an inch of land is an inch of gold, it is very fatal that this is insufficient.And landfill is dirty
Dye is not easy to control, and especially to underground water and atmosphere pollution, this requires it is anti-, to blend peculiar smell control preferable, but so into
This also corresponding increase.Landfill is to gradually decrease trend in China at present.Burning is China's garbage disposal more popular in recent years
Technique, because its minimizing is significantly just recommended to the utmost at present by some experts, but pollution problem caused by burning is more tight
The pollution of the toxic elements such as weight , bioxin is at present or it is difficult to control, the common people currently still hold resistance attitude.For economically, burn
It is maximum to burn early investment, but later stage income is also more apparent, especially public subsidies are more, and this point is also current construction incineration plant
One of the major reasons.Rubbish heap is exactly set to fertilizer by compost, but China's component of refuse is complicated, the fertilizer generally banked up not by
Peasant approves, therefore the current situation of compost is more awkward.Integrated treatment is current newer treatment technology, and rubbish need to be filled
Point sorting, from environmental protection for, it should be safer, also easily received by the common people, but its deficiency is skill
Art is complex, and also not as good as burning in income.
And hazardous waste is also existing in junk, and every year with the development of industry, solid waste rubbish
Constantly increasing.According to the survey report of green peace organization, developed country is with annual 50000000 tons of scale into development
Country's transhipment hazardous waste, from 1986 to 1992 year, developed country is to developing country and East European countries' transfer total amount
1.63 hundred million tons of hazardous waste.The transboundary movement of hazardous waste all has very important to developing country or even global environment
Harm.
Firstly, since the importer of waste is substantially all the technological means and Economic Energy for lacking processing and disposition hazardous waste
Power, the input of hazardous waste inevitably result in the damage to local environment and population health.Secondly, hazardous waste is not to sending out
Diffusion up to area is actually to escape disposition responsibility as defined in this country, and hazardous waste is made not obtain due processing and disposition
And be diffused among environment, the result of long-term accumulation will necessarily generate harm to global environment.The transboundary movement of hazardous waste
Harm also resides in, these wastes are entered in the case where the name of trade is covered, and importer is in order to fish for economic interests, not
Its issuable influence on environmental and human health impacts is cared for, so all cannot get due processing and disposition.Hazardous waste is got over
Border transfer has become one of serious Global Environmental Problems, such as takes no action to be controlled, global environment certainly will be caused sternly
It endangers again, and solid waste land-fill method most at present, lead to secondary pollution, while many organic matters are also landfilled in solid waste,
Therefore the recycling that organic matter realizes the energy how is handled the dangerous solid waste of organic matter and is obtained, it is quite important.
