Description
Technical field
The utility model belongs to environmental protection and energy saving technical field, be specifically related to one and reverse osmosis concentrated water is introduced filter backwash pond, carry out backwash by filter backwash water pump to strainer, the water after backwash enters the device that reverse osmosis concentrated water reclaims the reverse osmosis concentrated water recycling in pond again.
Background technology
Current reverse osmosis system is popularized gradually in Treatment of Industrial Water, and the disposal of reverse osmosis concentrated water also becomes a day by day important problem.Reverse osmosis is also known as reverse osmosis, and a kind of is impellent with pressure difference, isolates the membrane sepn operation of solvent from solution.Because it is contrary with the direction of naturally osmotic, therefore claims reverse osmosis.Feature due to reverse osmosis determines that its dense water is the water for concentrating various ion, and such as former water saltiness is about 500mg/L, and the normal reverse osmosis water rate of recovery is 80%, and the saltiness of its reverse osmosis concentrated water is at about 2500mg/L.Because reverse osmosis is through multiple pre-treatment, the indexs such as its dense water suspension are then very good.
The disposal options of reverse osmosis concentrated water conventional is at present directly discharge or partially recycled utilization, for power station, is usually used in ground flushing and coal yard sprinkling.
Utility model content
For the problems referred to above, main purpose of the present utility model is that providing a kind of introduces filter backwash pond by reverse osmosis concentrated water, carry out backwash by filter backwash water pump to strainer, the water after backwash enters the device that reverse osmosis concentrated water reclaims the reverse osmosis concentrated water recycling in pond again.
The utility model solves above-mentioned technical problem by following technical proposals: the device that a kind of reverse osmosis concentrated water is recycled, described device comprises backing system and carrys out water tank, backing system carrys out the some sections of reverse osmosis membrane assemblies in water tank downstream, each section of reverse osmosis membrane assembly is all connected with same product water tank, final stage reverse osmosis membrane assembly is connected with filter backwash pond by pipeline, filter backwash pond is connected with strainer by pipeline, pipeline between filter backwash pond and strainer is also provided with filter backwash water pump, the downstream of strainer is that reverse osmosis concentrated water reclaims pond.
In preferred embodiment of the present utility model: the hop count scope of described reverse osmosis membrane assembly is 2-3 section.
Positive progressive effect of the present utility model is: the device that the reverse osmosis concentrated water that the utility model provides is recycled, mainly reverse osmosis concentrated water is introduced filter backwash pond, carry out backwash by filter backwash water pump to strainer, the water after backwash enters reverse osmosis concentrated water again and reclaims pond.For power station, still meet through the backwash draining of strainer the needs that standard of drainage and ground flushing and coal yard spray.
The device of the reverse osmosis concentrated Water Sproading of the utility model utilizes reverse osmosis concentrated water as the backwash water of strainer, its water quality backwash characteristic be better than strainer water inlet, the backwash effect of strainer can be improved, have the steady running of system and well ensure effect.
The device of the reverse osmosis concentrated Water Sproading of the utility model meets the requirement that the waste water advocated now designs reuse step by step, decreases water displacement, has good environmental benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the device that reverse osmosis concentrated water is recycled.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the device that reverse osmosis concentrated water is recycled, as shown in Figure 1: the device in the utility model comprises backing system and carrys out water tank, backing system carrys out the some sections of reverse osmosis membrane assemblies in water tank downstream, each section of reverse osmosis membrane assembly is all connected with same product water tank, final stage reverse osmosis membrane assembly is connected with filter backwash pond by pipeline, filter backwash pond is connected with strainer by pipeline, pipeline between filter backwash pond and strainer is also provided with filter backwash water pump, the downstream of strainer is that reverse osmosis concentrated water reclaims pond.Generally speaking, the hop count scope of reverse osmosis membrane assembly can elect 2-3 section as, and what select in Fig. 1 is 2 sections.
The device that reverse osmosis concentrated water disclosed in the utility model is recycled, it is the characteristic according to making full use of reverse osmosis concentrated water, former water saltiness of illustrating is about 500mg/L, its reverse osmosis concentrated water is only that saltiness is slightly high, for about 2500mg/L, but the indexs such as its suspended substance are all equal to feed water by reverse osmosis, according to its characteristic, the anti-scouring water of reverse osmosis prime treatment facility (strainer) can be it can be used as, after its backwash, enter reverse osmosis concentrated water again reclaim pond, its water quality still meets draining and recycling.
The device that the utility model reverse osmosis concentrated water is recycled, mainly introduces filter backwash pond by reverse osmosis concentrated water, carries out backwash by filter backwash water pump to strainer, and the water after backwash enters reverse osmosis concentrated water again and reclaims pond.For power station, still meet through the backwash draining of strainer the needs that standard of drainage and ground flushing and coal yard spray.
The technique of the reverse osmosis concentrated Water Sproading of the utility model decreases strainer flooding quantity.General filter backwash water water rate of using by oneself is about about 5 ~ 8%, with the filter process water yield for 200m
3/ h counts, and its strainer flooding quantity saved is about 10 ~ 16m
3/ h, has good economic benefit.
The technology utilization reverse osmosis concentrated water of the reverse osmosis concentrated Water Sproading of the utility model is as the backwash water of strainer, its water quality backwash characteristic be better than strainer water inlet, the backwash effect of strainer can be improved, have the steady running of system and well ensure effect.
The technique of the reverse osmosis concentrated Water Sproading of the utility model meets the requirement that the waste water advocated now designs reuse step by step, decreases water displacement, has good environmental benefit.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
