Description
Technical field
The present invention relates to dialysis liquid waste treating apparatus, and it is a kind of of simple structure and low cost to elaborate, good purification
Dialysis effluent purifying device.
Background technology
It is known that kidney trouble is a global public health problem, the whole world need to there are about 2,400,000 patients with renal failure
It dialyses.Due to aging of population and the increase of diabetes illness probability, the quantity of patients with renal failure is also constantly rising（Often
Year increases 7-8%）.Chronic kidney disease can influence we 1/10th people.Suffer from for the people of renal failure for unfortunately, be good for
Health is gradually swallowed.At home, end stage renal failure patient, common people cry " uremia ", many patients by haemodialysis or
Kidney transplant substitutes renal function.
Kidney patient often has many troubles, for example to arrive hospital regularly and dialyse in treatment, with clear
Except the toxin of accumulation, but two kinds of currently a popular dialysis：Hemodialysis and peritoneal dialysis therapy, it is time-consuming longer,
And dialysis needs a large amount of dialyzate every time, this virtually increases the expenditure of medical expense, also limits two kinds of dialysis sides
The development that formula is dialysed to packaged type, because dialysis needs to carry a few decaliter dialyzates every time.
To solve problem above, dialyzate purify and circulating repetition uses, is the mainstream of technology today research.Into
Gone dialysis dialysis waste liquid in mainly contain urea, creatinine, phosphate, β2-microglobulin, be recycled for a long time during band
The endotoxins substance such as virus and bacteria entered, how to remove these substances is that the key technology that dialysis effluent purifying is reused is asked
Topic.With the development of dialyzate circulating technology, various novel dialyzate recovery systems are developed, such as Temasek science and engineering
The patent of institute（) and Zhuhai Jian Fan scientific ＆ technical corporation CN106111079A（CN205515729U patent) all propose using urase or
Adsorbent carries out circular regeneration to dialysis waste liquid.Adsorbent mainly includes zirconium base, aluminium base and activated carbon, and enzyme used is mainly urea
Enzyme.These substances are successively emitted in adsorbent equipment, and long-time service has the smaller adsorbent of grain size or urase entrance follows
Loop system causes the pollution of entirely dialysis fluid circulation, greater risk is brought to the dialysis of patient.
Invention content
Present invention aim to address above-mentioned the deficiencies in the prior art, provide a kind of of simple structure and low cost, purification effect
The good dialysis effluent purifying device of fruit.
Technical solution is used by the present invention solves above-mentioned the deficiencies in the prior art：
A kind of dialysis effluent purifying device equipped with outer housing, is equipped with supporting clapboard in outer housing top, supporting clapboard will be outer
Enclosure interior is divided into the adsorbent chamber of top and filter chamber two parts of lower section, and supporting clapboard is equipped with connection adsorbent chamber and filtering
The recirculation hole of chamber, adsorbent chamber is interior to be equipped with the porous adsorbing material for being adsorbed with urase, and porous adsorbing material absorption urase is unsaturation
It adsorbs, the outer housing above adsorbent chamber is equipped with waste liquid entrance；Hollow-fibre membrane, the both ends of hollow-fibre membrane are equipped in filter chamber
It being fixed in outer housing lower part through demarcation strip, outer housing is divided into the filter chamber of top and the reclaiming chamber of lower section by demarcation strip, in
The both ends of empty fiber membrane are connected with reclaiming chamber；Outer housing below reclaiming chamber is equipped with recovery port.
The urase adsorption capacity of heretofore described porous adsorbing material is 1-2mg/g, is adsorbed with the porous suction of urase
The urase adsorption capacity of enclosure material is 0.2-0.5mg/g.
Heretofore described hollow-fibre membrane is made of 500-10000 root film wires, film wire internal diameter for 220-350 microns,
Wall thickness is 40-60 microns, and film wire ecto-entad is divided into exodermis, middle layer and endodermis three parts, and the exodermis of film wire is in
The specific nano sorbing material that grain size is 1-8nm is distributed in interbed；1-2 microns of the skin thickness of film wire, was averaged
Filter opening diameter is 4-6 nanometers；0.5-5 microns of the endothelium layer thickness of film wire, average filtration aperture are 0.5-1 nanometers.
Heretofore described specific nano sorbing material is the silicon substrate and/or zirconium base of adsorbable various toxin ions
And/or magnesium-based sorbing material.
In silica, silicon chloride, phosphoric acid silicon particle that heretofore described silicon-based adsorption material material is grain size 1-8nm extremely
