The papermaking to zero discharge standard production line of the present invention, what well pumped has three places to use, and is domestic water respectively, makes
Paper machine industrial water and boiler feed water.Domestic water is directly outer to be arranged；Industrial water is used for felt and cleans and produce cleaning etc., is produced
Raw plain boiled water is pooled to white water chest；Boiler feed water supplies production and application for producing steam, and condensed water caused by industrial water returns
Deliver to boiler recycling.Various production waste water are discharged into air by wastewater collection pond collection with boiler smoke heating evaporation.
White waste paper and wet pulp form paper pulp by hydrabrusher size degradation, and add talcum powder or starch, through fiber separation
1 is evacuated to after machine processing#Stock tank, through 2#、3#The stock tank of series connection, delivered into by stock pump and rush stock tank through 1#、2#Desander desanding, then by upper
Slurry send 1#、2#Cylinder mould starching, paper pulp are transferred to woollen blanket through couch roll, are brought by woollen blanket to 1#、2#, vacuum tank be dehydrated, through pressure roller
Cylinder dried is transferred into paper by carrying roller after squeezing, then through rewinding, cut, be packaged into finished product storage.
Mthod of white water from paper making main source has plain boiled water, felt washing water, vacuum tank plain boiled water and pressure caused by net filtration on paper pulp
Plain boiled water caused by squeezing and carrying roller squeezing all flow to white water chest after collecting, the plain boiled water of white water chest is by being pumped to three eddy flows biologies
Tower processing is managed, the plain boiled water treated through eddy flow biological treatment tower delivers to hydrabrusher, defibrator and rushes stock tank respectively to be made
With.The afterbody waste water of sand cleaning machine is surfed the Net after desilting ditch flow to and rushes stock tank and paper pulp mixing certainly.
Eddy flow biological treatment tower：
Structure brief introduction：Volume 80m3, top is cylinder, and bottom is cone, and inside sets spiral to open sieve plate, plays water conservancy diversion
And filtration, bottom interconnect, separate respective function with valve, can also pass through each own effect of switch complementary of valve.
Main working process：
Plain boiled water is from 1#The cylinder bottom of biological treatment tower enters, and helically sluggish flow rises to top from flowing to current
2#、3#Biological treatment tower, hydrabrusher size degradation slurry is delivered to respectively through treated plain boiled water, defibrator and punching slurry hole are dilute
Release paper pulp use.Slurry is diluted to suitable concentration after size degradation and delivers to 1#、2#、3#Stock tank, so not having to typically in stock tank white
Water.
(3), main operational principle：
The plain boiled water that paper machine is collected contains substantial amounts of aerobic bacteria, produced in plain boiled water using corruption value matter be main matter it is rotten starch,
Rotten slurry, this is the main reason for hindering plain boiled water largely to reclaim use, and it can make smelly plain boiled water, fiber and other materials rot to become
Matter；A large amount of chemicals accumulation can also hinder the recycling of plain boiled water in plain boiled water simultaneously.And the plain boiled water in Hunan and Guangxi paper mill is through eddy flow
It can largely, for a long time be recycled after the processing of biological treatment tower, be because eddy flow biological treatment tower is water-tight equipment, completely cut off oxygen
The entrance of gas, so that aerobic bacteria, dead without life condition, therefore largely recycle and be possibly realized for plain boiled water；Together
When factory production fruit wrap to the less demanding of water quality, by simple processing, make bacterium in plain boiled water, fungi etc. aerobic
Bacterium, which does not work, to meet the needs of production, and this is also that white water recycle can a large amount of reuse preconditions.
Containing large amount of organic matter cellulose and starch etc. in mthod of white water from paper making, while also have with talcum powder etc. for major auxiliary burden
Material, be dissolved in after water and being formed using calcium ion as main cation.
Main function：
Suppress, kill aerobic bacteria, fungi grows, the white Organic substance in water is not sent out in eddy flow biological treatment tower
Raw effect, so as to not produce rotten slurry, rotten slurry；Anaerobic bacteria, fungi are cultivated simultaneously, makes white Organic substance in water in eddy flow biological treatment
Certain effect occurs in tower, anaerobic reaction to a certain degree occurs, carrying out mesophilic digestion obtains anion, sicker in plain boiled water
Processing to a certain extent, also a certain degree of disinfective action.
When mthod of white water from paper making leaves eddy flow biological treatment tower because without or only a small amount of aerobic bacteria, fungi and certain
Amount detests bacterium, therefore aerobe effect a small amount of effect without generation or only；And only a certain amount of anaerobic bacteria, that is, having
It can not be acted under conditions of oxygen.
The formulation of process conditions：
Aerobic bacteria, the life condition of fungi be have abundant nutriment, sufficient oxygen and suitable temperature and
PH value.And containing large amount of organic matter cellulose and suitable temperature in papermill whitewater, therefore plain boiled water eddy flow biological treatment tower
Process conditions formulation, aerobic bacteria is not worked, in addition kill aerobic bacteria, its process conditions most important condition is scarce
Oxygen processing environment, it is key factor to carry out eddy flow biological treatment tower encapsulation process, is secondly exactly the processing time for controlling plain boiled water,
It is exactly the pH value and temperature for regulating plain boiled water again.Therefore with regard to the life condition and eddy flow biological treatment tower of aerobic bacteria the characteristics of
Specially formulate following process conditions：
Oxygen content：Less than 5% or below 1mg/l.
Processing time：3h
Treatment temperature：30~40 DEG C
Plain boiled water pH value：6~8 (preferably no more than 8).
