Description
Technical field
The invention belongs to purified water preparing technical field, particularly to a kind of reverse osmosis concentrated reusing device for waste water and
Method.
Background technology
In recent years, the waste water handling problem that the industry purified water preparation systems such as pharmacy, food, chemical industry produce
Increasingly receive publicity.Reverse osmosis membrane technology (RO) has become as industrial circulation water treatment, desalinization
Important means in field.But use reverse osmosis technology to still suffer from two problems: one is reverse osmosis technology pair
Processed water quality pre-processing requirements is high, usually requires that employing sand, carbon filter, or super, microfiltration skill
Art is as pre-treatment.Causing equipment investment high and operating cost is high, two is that Water Sproading utilization rate is low, typically
Can only achieve about 70%, still have about 30% concentrated water discharge, discharge capacity is big, causes the wasting of resources and high salt
The pollution of degree waste water.
The processing mode of the current dense water of domestic RO has following several:
1. fraction concentrate recirculation is to before RO.RO concentrate recirculation can improve the response rate, increases membrane surface flushing stream
Speed, reduces dirt stifled；But reflux ratio is too high, can make again to raise into water salinity, increase the burden of film, affect the film longevity
Life.
2. industrial water is made in reuse.Due to no suspended substance in the dense water of RO, containing antisludging agent and there is pressure, can be used as
The filter backwashing water of device, water in dust removal, rinsing dusts and drags water, cooling water.
3. recycling.The dense water of RO of seawater desalting plant is used for salt manufacturing, can save salt pan, shortens and evaporates brine the cycle；
Suitably blend after pretreatment, can be used for culturing marine products.
4. distillation and concentration.Membrane Materials (MD) technology is a new technique, utilizes the temperature difference can be by dense water at ambient pressure
Reclaim (response rate > 95%) even crystallization as much as possible, but hydrophobic microporous the most economic, high-quality
Film not yet researches and develops maturation.
For first method, before fraction concentrate recirculation to RO, this processing mode is in current existing work
Skill embodies, has also reached certain effect.This mode is taked to need to consider the water quality situation of former water, simultaneously
Balance need to be found between the response rate and membrane lifetime.Because the factor by containing is the most, effect is the most inconspicuous.
For second method, industrial water is made in reuse, and this processing mode is often just with therein one little
Part, and the salinity of dense water, microorganism, other impurity content are higher, can work the mischief environment,
Cost recovery is the highest.So using the considerably less of the method at present.
Recycling method and distillation and concentration method are applicable to the dense water that large-scale water processes or sea water desalting equipment produces
Process, be not particularly suited for the dense water process that pharmaceutical purpose pure water equipment produces.
Summary of the invention
The invention aims to overcome the utilization rate of water in prior art on the low side, the water resource waste caused is tight
Weight, production cost is higher and environmental pollution etc..
The technical scheme is that, a kind of reverse osmosis concentrated reusing device for waste water, this device include reverse osmosis membrane,
Controller, conductivity probe, the first pneumatic operated valve and the second pneumatic operated valve, wherein the mouth of a river of coming of reverse osmosis membrane connects
Concentrated water drainage at the reverse osmosis unit of described reverse osmosis concentrated reusing device for waste water front road technique setting exports, described
The rear end of reverse osmosis membrane is provided with recycling outlet and floss hole, is provided with electricity at described recycling outlet
Conductance is popped one's head in, and this recycling outlet is connected simultaneously to the first pneumatic operated valve and the second pneumatic operated valve, and described second
The delivery outlet of pneumatic operated valve is connected to recycling can through pipeline, and the input of described controller connects described electrical conductivity and visits
Head, the outfan of described controller connects the first pneumatic operated valve and the second pneumatic operated valve.
Described reverse osmosis membrane uses used reverse osmosis membrane.
A kind of reverse osmosis concentrated water reuse method, comprises the following steps:
The dense water produced by reverse osmosis unit inputs the reverse osmosis membrane of reverse osmosis concentrated reusing device for waste water；
The dense water that cannot recycle through described reverse osmosis membrane processing is directly discharged, to through described reverse osmosis membrane
The recycling water detection electrical conductivity processed, when this electrical conductivity is below a setting value, then opens the second gas
Dynamic valve, is delivered to recycling can by this recycling water, when this electrical conductivity is more than described setting value, then opens
First pneumatic operated valve, emits this recycling water.
It is a feature of the present invention that without extra pressure-driven, utilize the pressure-driven that reverse osmosis concentrated water produces
?.Cost is the lowest, uses waste and old reverse osmosis membrane, plays the effect of resource reutilization.Reverse osmosis concentrated
The dense water part that this device of pressure-driven that water produces makes recycles, and another part discharges.Recycling portion
The water divided is back in recycling can.
Such scheme is by adding reverse osmosis concentrated reusing device for waste water between reverse osmosis concentrated water and recycling can, it is achieved that
Improve the utilization rate of water and reach saving water resource purpose.
This dense reusing device for waste water includes that waste and old reverse osmosis membrane, controller, two operated pneumatic valves and an electrical conductivity are visited
Head, before this conductivity probe is located at two operated pneumatic valves.
This conductivity probe flows through the water quality signal of two operated pneumatic valves for detection and is transmitted extremely by this water quality signal
Controller；This controller is used for comparing this water quality signal with this setting threshold value, and according to comparative result control
The opening and closing of two operated pneumatic valves of system
The most progressive effect of the present invention is, the reverse osmosis concentrated water recycling equipment of the present invention, utilizes reverse osmosis
The high pressure that dense water has itself is to drive dense water to recycle equipment, by the further place to reverse osmosis concentrated water
Reason, improve water utilization rate, it is ensured that produce water water quality, again can saving water resource, and then improve equipment producing water ratio
And economic benefit.
