Description
Technical field
The utility model belongs to purified water preparing technical field, particularly the reverse osmosis concentrated reusing device for waste water of one.
Background technology
In recent years, the waste water handling problem that the industry purified water preparation systems such as pharmacy, food, chemical industry produce more and more receives publicity.Reverse osmosis membrane technology (RO) has become the important means in industrial circulation water treatment, field of seawater desalination.But adopt reverse osmosis technology still to there is two problems: one is that reverse osmosis technology is high to processed water quality pre-processing requirements, usually require to adopt sand, carbon filter, or super, micro-filter technology is as pre-treatment.Cause that facility investment is high and working cost is high, two is that Water Sproading utilization ratio is low, generally can only reach about 70%, still have about 30% concentrated water discharge, and quantity discharged greatly, causes the pollution of the wasting of resources and high salinity waste water.
The processing mode of the dense water of current domestic RO has following several:
1. before small portion concentrate recirculation to RO.RO concentrate recirculation can improve the rate of recovery, increases membrane surface flushing flow velocity, reduces dirty stifled; But recurrence rate is too high, can makes again to raise into water salinity, increase the burden of film, affect membrane lifetime.
2. water of productive use is made in reuse.Due to no suspended substance in the dense water of RO, there is pressure containing Scale inhibitors, can be used as the backwashing water of filtration unit, water in dust removal, rinsing dusts and drags water, water coolant.
3. recycling.The dense water of RO of desalimtor is used for salt manufacturing, can save salt pan, shortens and evaporates brine the cycle; Suitably blend after pre-treatment, can be used for culturing marine products.
4. distillation and concentration.Membrane distillation (MD) technology is a new technology, utilize the temperature difference dense water can be reclaimed (rate of recovery >95%) even crystallization as much as possible at ambient pressure, but economy, high-quality dewatering microporous film not yet research and develop maturation at present.
For first method, before small portion concentrate recirculation to RO, this processing mode embodies to some extent in current existing technique, also reaches certain effect.Take this mode to need to consider the water quality situation of former water, balance need be found between the rate of recovery and membrane lifetime simultaneously.Because the factor being subject to containing is many, effect is also not obvious.
For second method, water of productive use is made in reuse, and this processing mode often just utilizes sub-fraction wherein, and the saltiness of dense water, microorganism, other foreign matter content are higher, and can be able to work the mischief to environment, cost recovery is also relatively high.So adopt the considerably less of this method at present.
Recycling method and distillation and concentration method are applicable to the dense water treatment of large-scale water treatment or sea water desalting equipment generation, and are not suitable for the dense water treatment of pharmaceutical purpose pure water equipment generation.
Utility model content
The purpose of this utility model is on the low side in order to overcome the utilization ratio of water in prior art, and the water resource waste caused is serious, production cost is higher and environmental pollution etc.
The technical solution of the utility model is, a kind of reverse osmosis concentrated reusing device for waste water, this device comprises reverse osmosis membrane, controller, conductivity probe, first pneumavalve and the second pneumavalve, wherein reverse osmosis membrane carry out the concentrated water drainage outlet that the mouth of a river is connected to the reverse osmosis unit that described reverse osmosis concentrated reusing device for waste water front road technique is arranged, the rear end of described reverse osmosis membrane is provided with recycling relief outlet and discharge outlet, conductivity probe is provided with at described recycling relief outlet place, and this recycling relief outlet is connected to the first pneumavalve and the second pneumavalve simultaneously, the delivery port of described second pneumavalve is connected to withdrawing can through pipeline, the input terminus of described controller connects described conductivity probe, the output terminal of described controller connects the first pneumavalve and the second pneumavalve.
Described reverse osmosis membrane adopts used reverse osmosis membrane.
Feature of the present utility model is, without the need to extra pressure-driven, utilizes the pressure-driven that reverse osmosis concentrated water produces.Cost is very low, adopts waste and old reverse osmosis membrane, plays the effect of resource reutilization.The dense water part that this device of pressure-driven that reverse osmosis concentrated water produces makes is recycled, and another part discharges.The water of recycling part is back in withdrawing can.
Such scheme, by adding reverse osmosis concentrated reusing device for waste water between reverse osmosis concentrated water and withdrawing can, achieves the utilization ratio of raising water and reaches saving water resource object.
This dense reusing device for waste water comprises waste and old reverse osmosis membrane, controller, two operated pneumatic valves and a conductivity probe, before this conductivity probe is located at two operated pneumatic valves.
This conductivity probe is for detecting the water quality signal that flows through two operated pneumatic valves and by this water quality Signal transmissions to controller; This controller is used for this water quality signal and this setting threshold value to compare, and controls the opening and closing of two operated pneumatic valves according to comparative result
Positive progressive effect of the present utility model is, reverse osmosis concentrated water recycling equipment of the present utility model, the high pressure utilizing reverse osmosis concentrated water itself to have recycles equipment to drive dense water, by the further process to reverse osmosis concentrated water, improve the utilization ratio of water, ensure to produce water water quality, again can saving water resource, and then improve producing water ratio and the economic benefit of equipment.
