Description
Technical field
The utility model is related to a kind of water treatment facilities, more particularly to a kind of Circulating water effluent purifies reutilization system.
Background technology
Recirculated water is as a kind of Industrial Water Saving measure, and widely used in many chemical plant, power plant, water consumption accounts for about entirely
70% or more of industrial water consumption.
Recirculated water is mainly used to condensed steam, cooling product or equipment, if cooling effect is poor, will influence production effect
The quality of rate, the yield and product that make product declines, and can even cause production accident.
For the using water wisely of maximum possible, the cycles of concentration operation for improving recirculated water as far as possible is needed, but with dense
The raising of demagnification number, fouling in water circulation system and corrosion factor more rely on water quality stabilizer, sterilization also with rising at double
In the use of the medicaments such as agent.Improving cycles of concentration too much can also be such that medicament (such as Quadrafos) stops in cooling water system
The time is stayed to increase and hydrolyze.
It is mainly led to the problem of in recirculated water operational process:
(1) incrustation scale:Since recirculated water constantly evaporates in cooling procedure, so that salt concentration in water is constantly increased, be more than
The solubility of certain salts and precipitate.It common are the dirts such as calcium carbonate, calcium phosphate, magnesium silicate.The quality of incrustation scale is dense, greatly
Big reduces heat transfer efficiency, and 0.6 millimeter of dirt is thick just to make heat transfer coefficient reduce 20%.
(2) dirt:Dirt is mainly made of organic matter, microbe colony and secretion, silt, the dust etc. in water, dirt
Quality it is soft, not only reduce heat transfer efficiency but also cause underdeposit corrosion, shorten service life of equipment.
(3) corrode:The corrosion of recirculated water heat exchanging equipment, mainly couple corrosion, Producing reason have device fabrication to lack
It falls into, the dirt that the mucus of corrosive ion (Cl-, Fe2+, Cu2+) and microorganism secretion is generated in oxygen gas and water sufficient in water
The consequence of the factors such as dirt, corrosion is extremely serious, even if uncontrolled extremely short time heat exchanger, hydraulic pipeline equipment scrapping.
(4) microorganism viscosity mud:Because being well suited for dissolved with sufficient oxygen, suitable temperature and rich foster condition in recirculated water
The growth and breeding of microorganism, such as control will rapidly result in water quality deterioration, smelly, blackening not in time, and cooling tower largely sticks dirt deposition
It even blocks, cooling and cooling effect declines to a great extent, equipment corrosion aggravation.Therefore circulating water treatment must control the numerous of microorganism
It grows.
For these for solving the problems, such as to generate in recirculated water operational process, in addition to adding a certain amount of water quality stabilizer, killing
The control of the medicaments such as microbial inoculum is outer, and circulation needs discharge part sewage and supplements new water quality.
Conventional Circulating water effluent water treatment technology includes:It is filtered off by laminated filter and is back to use recirculated water after removing part SS
System, the total hardness in ion exchange resin removal draining, acid adding processing, control PH7.5-8, electrodialysis or reverse osmosis desalination.
Electro-adsorption demineralization:Electrostatic field is formed by applying applied voltage, ion is forced to be moved at the electrode of opposite charges,
The charge and discharge of electric double layer are controlled, the ion concentration at electric double layer is changed, and are allowed to be different from bulk concentration.To realize
To the desalination of aqueous solution.The shortcomings that technology is that cost of investment is higher, causes operating cost higher.
Electrodialytic technique:Electrodialysis be under the action of applying direct current electric field, using the selective penetrated property of amberplex,
Make ion from the physical and chemical process moved in a part of water in another part water.Its major defect is to oils, solid etc.
It requires, equipment will produce dirt, need periodic cleaning, equipment replacement period short.
It is reverse osmosis:Reverse osmosis operation principle is to apply operating pressure in water inlet (concentrated solution) side to overcome naturally osmotic
Pressure.When the operating pressure higher than naturally osmotic pressure is applied to concentrated solution side, the flow direction of hydrone naturally osmotic will be inverse
Turn, water is produced in the purification that the moisture subdivision in water inlet (concentrated solution) becomes weak solution side by film.But the technology is to inflow requirement
It is more harsh.COD≤40mg/l, oil≤0.1mg/l, SDI≤3 are especially required in reusing sewage.And equipment cost is higher, fortune
Row cost is also very high.
Filter by laminated filter:Laminated filtering mainly removes the SS impurity in draining.When flow passes through filtered water inlet mouth
When filtering lamination in into filter, filtering lamination is tightly compressed under the action of spring force and waterpower, impurity
Grain is trapped within lamination crosspoint, and the water by filtering is flowed out from filter main channel.It is more and more with the particle of retention,
The pressure difference of Inlet and outlet water is increasing, when reach setting pressure difference when, filter switch valve, using filtered clear water to lamination into
Row backwash is drained into sewage disposal system processing after cleaning.A kind of its auxiliary controlled generally as circulating water quality,
Continuous filtration treatment is carried out to the part water quality in entire recirculated water, it is general to filter the 5-10% that water is entire recirculated water.With
Particle concentration in control loop water.Due to the characteristic of its object, the dissolubility calcium ions and magnesium ions in water body are not appointed
What practical removal effect.
Ion exchange resin:Ion exchange resin make mainly use ion-exchange process, in water be in ionic state sun,
Anion removes.For main application in the deep desalting treatment of draining, processing cost is higher, and the ion exchanged still needs
Evaporative crystallization or the outer waste water system that is discharged into is wanted to increase waste water treatment system processing load.
Acid adding processing:Control loop water PH7.5-8, water quality have lower crystallization trend at lower PH.It can only
It, cannot be really as the drainage sunk well mode of recirculated water as the supplement of cycle water management.Because with regard to acid adding processing itself
Speech, is only reduction of the pH value of water body, there is no any removals for the polluter in water body.
