Description
Technical field
The present invention relates to a kind of paper mill waste preprocessing technology.
Background technology
Paper is closely bound up with our mankind, is that human society is requisite.With development of the mankind to society, papermaking row
Industry has obtained very big development, but also causes huge destruction to the health and ecological environment of the mankind.According to statistics in recent years
Introduce that national pulping paper industry sewage discharge capacity accounts for national total amount of sewage discharge 10% 12%, occupy the 3rd, discharge
COD in sewage accounts for 40% 45%, occupies first.The severe contamination of paper-making industrial waste water and harm have been drawn
The extensive concern of people is played.
Therefore, for existing technology, the rubbish for processing paper mill mainly has three processing modes, and first, it is exactly profit
The burning that rubbish is carried out with incinerator, but burning waste or used plastics can produce a lot of toxic gases, such as two English, although
Two English can reach more than 800 degree in temperature and voluntarily decompose, but general paper mill is difficult incinerator in order to cost-effective
Temperature brings up to 800 degree of effect, and all can carry a certain amount of moisture inside in the rubbish of paper mill when burning, and rises burning
Come insufficient.Second, when exactly the place that the rubbish collective in paper mill is transported to regulation being filled, but being transported, not only transport
Oil transportation expense and transport manpower is significantly increased, and can cause very big pollution to the environment of landfill yard periphery when filling, meanwhile,
Landfill place rubbish to be filled is more and more, and As time goes on, landfill yard can be fewer and feweri, it is impossible to realizes sustainable development
The policy of exhibition.3rd, biodegradable processing method can be adopted, after exactly increasing some microorganisms on rubbish garbage decomposition
Reprocessing, but this processing method is also not evolved to the stage of maturation at home, it is impossible to well rubbish is degraded.
Therefore, there is process step confusion in existing papermaking garbage treating process, and treatment effeciency is low, and the pollution to environment is tight
Weight, while material recovery technology is immature, is unfavorable for cost-effective.
Content of the invention
The technical problem to be solved in the present invention be to provide in a kind of composting according to papermaking contained composition carry out according to
Secondary process, it is possible to increase treatment effeciency, reduces the pollution to environment, while by recovery section material, being conducive to cost-effective
Paper mill waste preprocessing technology.
For solving the above problems, the present invention is adopted the following technical scheme that：
A kind of paper mill waste preprocessing technology, comprises the following steps：
1) papermaking composting sorting：A, the papermaking composting for being blended with metal are poured in metal sorter, are passed through
The clipped wires such as the iron wire for containing, copper aluminium are rejected by metal sorter, remaining containing a large amount of sandstones, string and plastic components
Papermaking composting；B, the papermaking composting that step A is sorted after metal is poured in pulverizer so that pulverizer is by papermaking
Composting is crushed, while reducing papermaking composting to spraying water in the particle chamber of pulverizer in crushing process
The dust produced in crushing process；C, by step B crush after papermaking composting pour in stirring pool, fast by mixer
Papermaking composting in stirring pool is quickly stirred by speed so that the sandstone and sludge settling in papermaking mixed waste is in pond
Bottom, is suspended in string in water, plastic components and paper pulp with flow direction separate tank, and the sandstone of bottom of pond and sludge are received
Collection otherwise processed；Mixing water containing string, plastic components and paper pulp in D, step C is slow by mixer in separate tank
Slow agitation, the PP and PE in plastic components swims in the water surface, and is fished for by machine for fishing out, and in plastic components, PVC is deposited in separation
Bottom of pond, then drains into the water containing string and paper pulp in sedimentation basin；
2) papermaking wastewater garbage disposal：By step 1) in concrete steps D obtained in the water containing string and paper pulp
Drain in sedimentation basin, and microbial flocculant 40-60 parts are added according to every cube of sewage, will be precipitated by microbial flocculant
String and paper pulp in pond condenses into flocculation block and is deposited to bottom of pond, and the sludge bulking rich in string and paper pulp is obtained；
3) sewage purification：By step 2) in the sewage for removing string and paper pulp drain in aerator, by dissipating
Gas impeller, microbubble is directly injected in raw sewerage, and in the presence of remaining microbial flocculant, suspension is sent out
Biological reason flocculation and chemical flocculation, so as to form big suspension floc sedimentation, float in the buoyance lift effect low suspension thing floc sedimentation of bubble population
Upper liquid level forms scum silica frost, is separated from the water using Slag Scraping Device, and sewage purification is up to standard, and discharges；
4) papermaking garbage reclamation is utilized：By step 1) in concrete steps D in PP, PE remanufacture second third for fishing for mix
Material, by step 2) obtained in fiber sludge block be transported in decontamination of biological processing pond and processed, be eventually fabricated and can be applied
The bio-bacterial manure of fertilizer.
Further, the step 1) concrete steps C in stirring pool every cube of water body in be provided with a mixer,
And rotating speed be 300 turns per minute, the step 1) concrete steps D separate tank every cube of water body in be provided with a stirring
Machine, and rotating speed is 150 turns per minute.
Further, the step 2) in microbial flocculant for microorganism wall extract flocculant, including
Glycoprotein 10-14 parts, mucopolysaccharide 8-16 parts, protein 9-15 parts and cellulose 13-19 parts.
Beneficial effects of the present invention are：Therefore a large amount of solid of papermaking generation can be reduced by paper mill waste preprocessing technology
Body and liquid refuse, while the recovery section material when the rubbish that papermaking is produced is processed, reduces the waste of resource, can increase and make
The economic benefit of paper plant, furthermore, the pretreatment to papermaking composting can avoid heavy metal in sewage or other are harmful
Material is flowed in river and causes secondary pollution.
