Description
Technical field
It the utility model is related to solid waste pollutant process and utilization technology field, and in particular to a kind of solid waste pollutant
Processing system.
Background technology
The solid waste pollutant envelope everything for producing and meeting with national economy and people's life, and pollute more and more tighter
Weight, it has also become restrict the bottleneck of the national economic development and human settlement's improvement.
Domestic waste is stacked, pollutes environment everywhere, and garbage loading embeading takes a large amount of arable lands, and refuse landfill is even more one
Permanent pollution sources.In addition, incineration treatment of garbage discharges the pollutants such as a large amount of CO2, nitrogen oxides, oxysulfide, bioxin, meeting
Cause atmosphere pollution.Town and country biomass garbage is all producing daily, and quantity amount is entered greatly, it is necessary to employ a tremendous amount of manpower with automobile
Row is collected and transport, takes a large amount of human and material resources and financial resources.
In straw from village annual two season, about 1000kg, partly it is incinerated；All over the mountains and plains fast-growing shrub, small weedtree are wet
The annual plants such as the littoral reed of ground, rivers and lakes, year after year, itself goes out certainly mostly.The rural area biomass place of production disperses, thing
Material is loose, storage, transport difficult；Annual plant value is low, does not increase income arduously, peasant does not have enthusiasm；Rural area biomass should
Do not developed with market, it is impossible to produce high value-added product, some biomass processing enterprises rely on merely government subsidy
Existence.The renewable biomass such as stalk are not developed for a long time, and part stalk is polluted by on-site incineration, growth encourage haze,
Government prohibits by force without cease.
Mushroom is a new industry in rural area, and culture medium is with organic matters such as straw, wood chip, dry fowl and animal excrement, rapeseed cakes
Based on, addition chemical fertilizer, land plaster, lime and other trace elements.Gone out of use after culture medium loss of function, to environment and Rural Water
System pollutes：First, corruption, fouling, produce a large amount of harmful substances；Second, going mouldy, mould and pest infestation are caused；Third, mushroom
Mushroom culture medium packaging bag, it is white pollution, is difficult to degrade for a long time.
Afforestation is due to improving city environmental quality, alleviating urban heat land effect, in terms of maintaining balance of city ecosystem
Special role and be valued by people.National urban built-up areas greening area coverage is increasing, afforestation coverage rate, greenery patches
Rate more and more higher, the thing followed are that urban landscaping discarded object is more and more.As dry branches and fallen leaves, branch, turf-mown thing,
Weeds and residual flower etc., afforestation discarded object have aggravated the burden of urban garbage disposal.
Had a large capacity and a wide range by the solid waste that oil, chemical products pollute, petrochina produces drilling well and discarded every year according to data
Ten thousand tons of thing 550-600, shale gas exploitation oil base drilling well individual well discarded object are 2-3 times of conventional drilling；City basic engineering construction
The mud and belongings, all kinds of wastewater sludges, chemical engineering sludge etc. put aside as useless in drilling.At present, do not have also to oil, chemical pollution thing
Effective processing method, is burned using combustion furnace, produces CO2, nitrogen oxides, the pernicious gas such as oxysulfide, bioxin；Using
" indigenous oil refining " mode separates oil component and easily blocks coking, produces poisonous and harmful substance；Parsed using chemicals, medicament is difficult
With separation, residue can not be innoxious；Using accumulation, the landfill of being digged pit after de- steady, dehydration, once rain erosion, pollutant effusion, make
Into permanent harm；Using curing process, considerable firming body is soybean residue, with rain erosion and action of thermal difference, firming body
Disintegrate, pollutant releases, and is much troubled for a long time.
At present, for above-mentioned rubbish, the processing mode of solid waste, more or less there is negative effect to environment, and rubbish,
Useful value in solid waste does not also use rationally, causes the waste of resource.
