Description
Technical field
The present invention relates to a kind of paper mill waste preprocessing technologies.
Background technique
Paper and our mankind are closely bound up, are that human society is essential.Development with the mankind to society, papermaking row
Industry has been greatly developed, but also causes huge destruction with ecological environment to the health of the mankind.According to statistics in recent years
It introduces national pulping paper industry sewage discharge amount and accounts for about 10%-the 12% of national total amount of sewage discharge, occupy third position, discharge
COD in sewage accounts for about 40% -45%, occupies first.The serious pollution and harm of paper-making industrial waste water have been drawn
The extensive concern of people is played.
Therefore, for existing technology, the rubbish in paper mill is handled mainly there are three processing mode, first, it is exactly benefit
The burning of rubbish is carried out with incinerator, many toxic gases can be generated by burning waste plastic, such as Xiang bioxin, although
Bioxin can reach 800 degree or more in temperature and voluntarily decompose, but general paper mill is difficult incinerator for save the cost
Temperature is increased to 800 degree of effect, and all can make to burn with a certain amount of moisture inside in the rubbish of paper mill when burning
Come insufficient.Second, when the rubbish collective in paper mill being exactly transported to defined place and is filled, but being transported, not only transport
Oil transportation expense and transport manpower is significantly increased, and very big pollution can be caused to the environment on landfill yard periphery when landfill, meanwhile,
The landfill place rubbish to be filled is more and more, and over time, landfill yard can be fewer and fewer, can not achieve sustainable development
The policy of exhibition.Biodegradable processing method can be used in third, exactly increases some microorganisms on rubbish after garbage decomposition
Reprocessing, but this processing method can not well degrade to rubbish at home there are no the mature stage is developed to.
Therefore, for existing papermaking garbage treating process there are processing step confusion, treatment effeciency is low, tight to the pollution of environment
Weight, while material recovery technology is immature, is unfavorable for save the cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of ingredient according to contained in papermaking composting carry out according to
Secondary processing can be improved treatment effeciency, reduce the pollution to environment, while by recovery section material, be conducive to save the cost
Paper mill waste preprocessing technology.
To solve the above problems, the present invention adopts the following technical scheme that：
A kind of paper mill waste preprocessing technology, includes the following steps：
1) papermaking composting sorts：A, the papermaking composting for being blended with metal pours into metal sorter, passes through
Metal sorter rejects the clipped wires such as the iron wire contained, copper aluminium, and residue contains a large amount of sandstones, plant fiber and plastic components
Papermaking composting；B, the papermaking composting after step A to be sorted to metal pours into pulverizer, so that pulverizer is by papermaking
Composting is crushed, at the same it is intracavitary to the particle of pulverizer in crushing process spray water, reduce papermaking composting
The dust generated in crushing process；C, the smashed papermaking composting of step B is poured into stirring pool, it is fast by blender
Speed quickly stirs the papermaking composting in stirring pool, so that the sandstone and sludge settling in papermaking mixed waste are in pond
Bottom, plant fiber, plastic components and the paper pulp to suspend in water are received with flow direction separate tank, and by the sandstone of bottom of pond and sludge
Collect otherwise processed；D, the mixing water containing plant fiber, plastic components and paper pulp is slow by blender in separate tank in step C
Slow to stir, PP and PE in plastic components swim in the water surface, and are fished for by machine for fishing out, and PVC is deposited in separation in plastic components
Then bottom of pond drains into the water containing plant fiber and paper pulp in sedimentation basin；
2) papermaking wastewater garbage disposal：By the water containing plant fiber and paper pulp made from the specific steps D in step 1)
It drains into sedimentation basin, and adds microbial flocculant 40-60 parts according to every cube of sewage, will be precipitated by microbial flocculant
Plant fiber and paper pulp in pond condense into flocculation block and are deposited to bottom of pond, and the sludge bulking rich in plant fiber and paper pulp is made；
3) sewage purification：The sewage of removal plant fiber and paper pulp in step 2) is drained into aerator, by dissipating
Gas impeller, microbubble is directly injected into raw sewerage, under the action of remaining microbial flocculant, suspended matter hair
The flocculation of biology reason and chemical flocculation, to form big suspended matter floc sedimentation, suspended matter floc sedimentation is floating under the buoyance lift effect of bubble population
Upper liquid level forms dross, is separated from the water using Slag Scraping Device, and sewage purification is up to standard, and is discharged；
4) papermaking garbage reclamation utilizes：PP, PE remanufacture second third fished in specific steps D in step 1) is mixed
Material, fiber sludge block made from step 2) is transported in decontamination of biological processing pond and is handled, being eventually fabricated can be applied
The bio-bacterial manure of fertilizer.
Further, it is provided with a blender in every cube of water body of stirring pool in the specific steps C of the step 1),
And revolving speed is 300 turns per minute, is provided with a stirring in every cube of water body of the specific steps D separate tank of the step 1)
Machine, and revolving speed is 150 turns per minute.
Further, the microbial flocculant in the step 2) is the flocculant of microorganism wall extract, including
10-14 parts of glycoprotein, 8-16 parts of mucopolysaccharide, 9-15 parts of protein and 13-19 parts of cellulose.
Beneficial effects of the present invention are：The a large amount of solid of therefore papermaking generation can be reduced by paper mill waste preprocessing technology
Body and liquid refuse, while the recovery section material when handling the rubbish that papermaking generates, reduce the waste of resource, can increase and make
The economic benefit of paper plant, furthermore, the pretreatment to papermaking composting can be avoided the heavy metal in sewage or other nocuousness
Substance, which is flowed into river, causes secondary pollution.
