Description
Technical field
The utility model relates to water-treatment technology fields, and in particular to a kind of water process dress for family hemodialysis instrument
It sets.
Background technique
Kidneys filter blood removes discarded substance, maintains the metabolism of entire body.If renal failure, give up
Object is accumulated in vivo, eventually poisons human body.Rend dialysis is also known as artificial kidney, also referred to as blood dialysis (abbreviation hemodialysis) or washes
Kidney.Dialysis is to be diffused into the principle of water (or buffer) through semi-permeable membrane by small molecule, by small molecule and large biological molecule point
A kind of separating and purifying technology opened.It is one kind of blood purification technology, utilizes semi-permeable membrane principle, by diffusion, to fluid
Interior various harmful and extra metabolic wastes and excessive electrolyte remove in vitro, achieve the purpose that purify blood, and reach
Correct the purpose of Water-Electrolyte and acid-base balance.Relying on majority in 500,000 patients that dialysis sustains life in the whole world is hemodialysis.
Hemodialysis has the certain significance to patient symptom, extension life cycle is mitigated.
Family hemodialysis is a kind of by patient oneself operation at home, dialysis treatment mode generally three times a week.
Compared to dialysis center hemodialysis, family's hemodialysis has many good qualities.It can allow the dialysis treatment of patient freer, and arrangement of time is more
Flexibly, dialysis time can be arranged according to the work and life timetable of patient completely, the work to patient and families of patients
It is influenced with life smaller.The patient of family's hemodialysis does not need continually hospital treatment yet, and monthly or the longer time is multiple to outpatient service
Looking into can.Research finds that family hemodialysis includes following advantage: 1) preferably managing and controlling patient's blood pressure.2) it improves
The sleep quality of patient.3) cross-infection is reduced, case fatality rate is reduced.4) medical expense is lower.Certainly, due to family's hemodialysis treatment
The complexity of operation, not all patient are suitable for family's hemodialysis treatment.Patient has to be familiar with all dialysis procedures, knows
How road operates dialyzer, and all kinds of problems of the processing including complication, operate in strict accordance with the guidance of doctor in time.Blood
Liquid dialysis is the primary treatments of current kidney trouble, during carrying out a Rend dialysis, the use of each patient's needs
Water is about 160L.The water quality of water for dialysis directly determines the effect and safety of dialysis procedure.Hospital is provided with special
Water process circulator can reduce disposable water consumption.The huge water requirement that home dialysis faces once to dialyse will just face water
The problem of processing.
Contain K in Rend dialysis waste liquid+、Na+、Ca2+、Mg2+、Cl-、HCO3 -With some blood organic toxins.Wherein organic poison
Element includes urea, creatinine and uric acid.The organic toxin good water solubility of these small molecules, molecular structure stabilized, conventional water process
Technique (such as flocculation, absorption and biochemical method) is very unsatisfactory to its treatment effect.
Water content is big in haemodialysis waste liquid, and pollutant concentration is low, is all as waste liquid direct emission under normal circumstances.But
It is when carrying out family hemodialysis, this is clearly a kind of huge water resource waste.Direct emission not only waste water resource,
Serious pollution can be also caused to environment, develop efficient purification process thus with important theory and realistic meaning.Due to
Dialysis membrane does not have selectivity for the noxious material in dialyzate, and the noxious material in water for dialysis can not only damage dialysis and set
Standby, more seriously harmful substance can diffuse into patient's body by dialysis membrane, cause patient to occur acute and chronic concurrent
Disease, therefore the water quality of water for dialysis is directly related to the efficacy and saferry of haemodialysis.
Ultrafiltration is a kind of pressurization membrane separation technique, i.e., under pressure, passes through small molecule solute and solvent certain
The special film in aperture, and macromolecular solute is prevented one side of film to be stayed in, so that macromolecular substances be made to have obtained portion from penetrating
The purifying divided.Ultrafiltration principle is also a kind of membrane separating process principle, and ultrafiltration utilizes a kind of pressure activated film, is made in extraneous motive force
With colloid in lower trap water, particle and the relatively high substance of molecular weight, and water and small particles of solute penetrate the separation of film
Journey.By the screening of the micropore of film surface can molecular cut off be 3*10000-1*10000 substance.When treated water is by means of outer
When the effect of boundary's pressure passes through film surface with certain flow velocity, the solute of hydrone and molecular weight less than 300-500 penetrates film, and
Particle, macromolecular greater than fenestra etc. are since sieving actoion is trapped, so that water be made to be purified.That is, when water passes through
After ultrafiltration membrane, a large amount of organic matter etc. in water can remove.This is but also ultrafiltration becomes a kind of reliable reverse osmosis pre-treatment method.
Reverse osmosis also known as reverse osmosis, one kind isolating the UF membrane operation of solvent using pressure difference as motive force from solution.
Pressure is applied to the feed liquid of film side, when pressure is more than its osmotic pressure, solvent can be made reversed against the direction of naturally osmotic
Infiltration.To the solvent that the low-pressure side in film is penetrated, i.e. penetrating fluid；The solution that high-pressure side is concentrated, i.e. concentrate.Cause
It is contrary with naturally osmotic for it, therefore claim reverse osmosis.According to the different osmotic of various materials, so that it may be seeped using being greater than
The reverse osmosis pressure pressed thoroughly, i.e. hyperfiltration achieve the purpose that separation, extraction, purifying and concentration.
Take boron-doped diamond thin-film electrode (BDD) as the cleaning equipment of core, is used for electrochemical process water as a new generation
The electrode material of processing, compared with the traditional materials such as noble metal and ti-based coating electrode (DSA), BDD electrode has best sun
Pole oxidability, widest potential window and highest current density.The sp of diamond-stable3Structure make it have it is corrosion-resistant,
The good characteristics such as high temperature resistant, anti-oxidant and resistance tocrocking.
Under electric field action, it is free that BDD electrode surface can successively generate the free state hydroxyl with superpower oxidisability
Base OH(standard oxidizing potential is 2.80V, close to the 2.87V of simple substance fluorine gas), peroxy radical HO2, ozone O3And hydrogen peroxide
H2O2Equal oxide species, also to various microorganisms, have strong killing including bacterium and virus while reacting with waste liquid
Effect.
Waste water water can be improved to a certain extent with traditional method for treating water (such as physical method, chemical method, bioanalysis)
Matter situation, but have respective insufficient or disadvantage.Wherein, physical method is excluded impurity in the way of absorption, precipitating or barrier etc.
Outside.As classical activated carbon adsorption can effective purifying water body need but as the extension charcoal adsorption capacity of time will constantly weaken
It is periodically cleaned and is replaced, and it can not aoxidize organic pollutant degradation, thus may cause phase transfer, make problem
Further deteriorate.More seem unable to do what one wishes when especially containing organic pollutant in the industrial wastewater of high concentration.Chemical method
Including oxidation processes, neutralisation treatment, coagulating treatment etc., possess the ability for fast and effeciently removing pollutant, however in practical behaviour
It is likely to occur recycling difficulty in work, is easy to generate secondary pollution problems.In contrast, bioanalysis is with its economy and green
The feature of environmental protection becomes one of water treatment technology most popular at present, but works as in waste water there are hardly degraded organic substance or containing bio-toxicity
When pollutant, solely it is difficult to obtain ideal degradation effect using the Biochemical method waste water.And biological treatment effect mentions
Liter is difficult to grasp and uncertainty is very high.
