Description
One, technical field：
The utility model is related to a kind of waste water treatment systems, are recycled more particularly to a kind of paper industry paper machine white water
System belongs to the waste reprocessing technical field of pulping and paper-making industry.
Two, background technology：
The water that paper machine is deviate from during sheet forming from wet end, suction box and press section is known as mthod of white water from paper making.Plain boiled water
It is the main source that paper-making process generates waste water, wherein containing a large amount of fiber, inorganic filler and various chemical assistants.Papermaking is white
The meaning and purpose of water process are fiber, filler and the other materials recycled in plain boiled water, and are back to production, reduce raw material, object
Material consumption, lowers production cost.Equally, treated, and plain boiled water reuse production process, reduction waste water will also generate to greatest extent
Amount reduces waste water end-o f-pipe -control expense.
The plain boiled water that paper industry paper machine generates at present, in addition to enriched water fully recovering diluted slurry, the dilute white water recycling in part
Production constantly accumulates in cyclic process since dilute plain boiled water of reuse production contains a large amount of solid content, quality of reused water is caused to dislike
Change, influences product quality, increase Pollutants in Wastewater concentration.Equally it is discharged into the Pollutants in Wastewater load of waste water processing station
Height increases wastewater treatment difficulty.It thereby results in mthod of white water from paper making to fail to make full use of, a large amount of fibers, filler are lost in, and are reduced and are made
The economic benefit of paper industry, and adverse effect is produced to environment.
Three, utility model content：
Technical problem to be solved in the utility model is：Overcome the deficiencies of the prior art and provide a kind of paper industry paper
Machine white water recycle processing system, plain boiled water is handled using super efficiency shallow air flotation principle, and treated, and plain boiled water part is used for papermaking vehicle
Between pulp dilution, pulp dilution and pulp washing of remaining reuse slip house etc., a few part is used for the irrigation in farmland, recycling
Fiber and filler be reused in production.
The utility model is for the technical solution adopted for solving the technical problem：
A kind of paper industry paper machine white water recovery and processing system, including it is collecting-tank, sewage pump, shallow air-floatation pond, molten
Gas system, water distribution system, clear water reserviors, pulping and paper-making device, farmland irrigating device, dross pond, sludge lifting pump and sludge dewatering
Machine, the collecting-tank, sewage pump, shallow air-floatation pond, air dissolving system pass sequentially through pipeline with water distribution system and connect, described shallow
Layer flotation tank is connected by pipeline with the clear water reserviors；Paper machine white water is collected through trench into collecting-tank, then by sewage lifting
Pump is promoted in shallow air-floatation pond, and PB1 gene is added in sewage lifting pump intake, enters nozzle in shallow air-floatation pond and adds
Enter sewage-treating agent polyacrylamide PAM, after sewage sequentially enters shallow air-floatation pond, air dissolving system, water distribution system are reacted
It is again introduced into shallow air-floatation pond；Clear water in shallow air-floatation pond is extracted into clear water reserviors, and majority enters pulping and paper-making device
Middle cycling and reutilization, few be partly discharged into farmland irrigating device carry out cycling and reutilization；It is discharged from shallow air-floatation pond
The dross come enters in dross pond, and the dross in dross pond, which is drawn onto through sludge lifting pump forcing pump in sludge dewatering equipment, to be taken off
Water process, with using it for anything else, the liquid taken off is discharged into collecting-tank, is then recycled and is located again for dewatered dry mud outward transport
Reason；Supernatant in dross pond is also discharged into collecting-tank, then carries out recycling reprocessing.
Liquid portion can be separated by solid-liquid separation by fibre recovery machine in the shallow air-floatation pond, solid fiber reuse regeneration
Production, liquid waste are back to the molten gas that next step is carried out in shallow air-floatation pond, water distribution reaction.
The utility model handles plain boiled water using super efficiency shallow air flotation theory, and plain boiled water part is starched for paper machine room after processing
Material dilution, pulp dilution and pulp washing of remaining reuse slip house etc., the fiber and filler of recycling are reused for producing.Super effect is shallow
Layer air supporting is theoretical, can significantly reduce the diameter of microbubble.Microbubble diameter is only about 5 μm average, carries certain charge, changes significantly
Become hydrone surface tension intensity, absorption is dissolved in the colloid macromolecules of water.With average about 120 μm of horizontal ratio domestic and international at present
Relatively at least reduce 10 times.Due to working as the timing of molten tolerance one, the gross area of microbubble and its diameter square are inversely proportional, thus micro-
The gross area of bubble at least increases 100 times, and the closeness of microbubble then increases nearly hundred times.Theoretical research and experiment are equal
Show that microbubble diameter is smaller, the trend that bubble adsorbs suspended matter is stronger, and adsorption capacity is bigger, this can with interface can it is theoretical come
It explains, the microbubble gross area is equivalent in waste water solid, water in geometry number increase, total face of gas three-phase increases in geometric progression, in
It is that they try hard to substantially enhance by the trend of absorption reduction surface energy.In air supporting theory, suspended matter is removed from the separation of water body
Except bubble absorption, bubble jacking, flco adsorption mechanism, there is also so-called " bubble, which is wrapped up in, to be taken " effects, it is referred to：Part
The fine suspension that do not adsorbed with bubble or flco, in intensive bubble uphill process, no matter how tiny fine suspension is,
Still much larger than hydrone, they will likely be carried under one's arms to be wrapped up in the bubble gap of bubble population and take to the water surface and detach grain size.It is aobvious
So, bubble population is more intensive, this effect will be stronger, and the suspended matter that can be carried under one's arms also will be more tiny.
The utility model has used " shallow pool theory ", and it is all static to force water distribution, Inlet and outlet water, and microbubble is viscous with wadding grain
The attached entire dissolved air flotation process being happened at including contact zone, dross are instantaneously discharged, and water disturbance is small, goes out aqueous suspension
Low, solid content height of slagging tap, removal efficiency is up to 93~99.5%.
In the utility model, PB1 gene is added in pump entrance, entering nozzle in shallow air-floatation pond is added sewage
Inorganic agent polyacrylamide PAM.PB1 gene is the important coagulant in Water warfare field, to low temperature, low turbid and high muddy water
With high-efficient purification effect；Polyacrylamide PA）For high molecular weight water soluble polymer, do not dissolve in most of organic solvents, by from
Sub-feature point can be divided into nonionic, four type of anion, cation and amphoteric, have good flocculability, can reduce
Frictional resistance between liquid.
