Description
Technical field
The present invention relates to a kind of methods of haemodialysis wastewater treatment.
Background technique
Haemodialysis (hemodialysis, HD) is one of acute or chronic renal failure kidneys of patients Replacement Therapy.
It by by internal blood drainage to external, through one by (porous dialysis membrane) in the dialyzer that is formed without several hollow fibres,
Blood electrolyte solution (dialyzate) similar with concentration containing body is inside and outside hollow fibre one by one, by disperse/to flowing into
Row mass exchange removes intracorporal metabolic waste, maintains electrolyte and acid-base balance;Moisture excessive in vivo is removed simultaneously, and
The whole process of blood recovery by purification is known as haemodialysis.The appearance of hemodialysis technology is chronic renal failure, urgency
Property renal failure, multiple organ failure, severe trauma, acute necrotic pancreatitis, potassemia, hypernatremia, in acute alcohol
The effective treatment method of the offers such as poison.To patient symptom is mitigated, extension life cycle has the certain significance, and the acute and chronic kidney of rescue
One of effective measures of functional failure.
It is water that electrolyte solution applied by blood dialysis, which forms main ingredient, haemodialysis with water need by
The techniques such as reverse osmosis are handled.Each patient will bear the filtration of 15000 ~ 30000L water for 1 year, it is contemplated that year China at present
There are hundreds of thousands of patients to need to carry out haemodialysis, water consumption is huge.In blood dialysis generated waste liquid mostly directly into
Row processing, causes the waste of water resource.
Summary of the invention
The invention discloses a kind of haemodialysis waste water recycling method, the method for the present invention recycles haemodialysis wastewater treatment speed
Degree is fast, and forward osmosis membrane average treatment amount is up to 18 L m-2 h-1, 60% or more can be saved water, waste water row is greatly reduced
It puts, all operations are atmospheric pressure at room operation, and low energy consumption.
A kind of method of haemodialysis waste water recycling carries out in the steps below in the present invention:
It by haemodialysis waste liquid and draws liquid and each leads into forward osmosis membrane both ends, handled, then reuse, be passed through that draw liquid dense
Degree is that it is identical according to solute ratio in blood dialysis solution to draw liquid solute component ratio between 10 ~ 20 times of haemodialysis concentration.
The kit form of the forward osmosis membrane uses flat, rolling or hollow fiber form membrane module.
A kind of haemodialysis waste water recycling process of the present invention, process is simple, and Preparation equipment occupied area is small, can connect
Continuousization, automatic operation, forward osmosis membrane average treatment amount is up to 18 L m-2 h-1, 60% or more can be saved water, significantly
Discharge of wastewater is reduced, all operations are atmospheric pressure at room operation, and low energy consumption.
Figure of description 1 be 1 membrane distillation method of embodiment processing dialysis waster water process schematic device, 1 --- the first storing
Tank, 2 --- pump, 3 --- membrane distillation unit, 4 --- the 4th storage tank, 5 --- the second storage tank, 6 --- third storage tank,
7 --- sampling valve.
Specific embodiment
Embodiment 1: being illustrated in conjunction with Fig. 1, and the method for haemodialysis waste water recycling is by following steps in present embodiment
Suddenly it carries out:
One, the haemodialysis waste liquid that hemodialysis unit generates is delivered in the first storage tank 1；
Two, dense electrolyte solution is configured, solute component ratio and blood dialysis solution solute ratio are identical, and concentration is haemodialysis
16 times or more of liquid are placed in the second storage tank 5 and third storage tank 6；
Three, solution in solution in step 1 and step 2 is delivered to forward osmosis membrane both ends, used positive infiltration with pump respectively
Film is commercial polyamide forward osmosis membrane, is not less than 99.5% to monovalence salt rejection rate, membrane module is rolled membrane module；
Four, haemodialysis waste liquid concentrate is collected to waste liquid tank；
Five, liquid dilution will be drawn to be back in the second storage tank 5, concentration is monitored on-line, when concentration is reduced to 4 times of haemodialysis
When liquid concentration by liquid pumping in the second storage tank 5 into the 4th storage tank 4；
Six, liquid in third storage tank 6 is delivered in the second storage tank 5, and reconfigures and draws in third storage tank 6
Liquid；Seven, the diluted liquid that draws will be passed through in the 4th storage tank 4 and is further diluted to blood dialysis solution concentration, it is single to be delivered to dialysis
Member forms circulation.
Fast using the method for the present invention recycling haemodialysis wastewater treatment speed, forward osmosis membrane average treatment amount is up to 24 L
m-2 h-1, entire technique can save water 72% or more, and discharge of wastewater is greatly reduced, and all operations are atmospheric pressure at room behaviour
Make, low energy consumption.
Claims (2)
1. a kind of method of haemodialysis waste water recycling, it is characterised in that the method for the haemodialysis waste water recycling is by following
What step carried out:
It by haemodialysis waste liquid and draws liquid and each leads into forward osmosis membrane both ends, handled, then reuse, be passed through that draw liquid dense
Degree is that it is identical according to solute ratio in blood dialysis solution to draw liquid solute component ratio between 10 ~ 20 times of haemodialysis concentration.
2. a kind of method of haemodialysis waste water recycling according to claim 1, it is characterised in that the component shape of the forward osmosis membrane
