Embodiment 1

[0039]Embodiment one is basically as attached figure 1 Shown: a kind of RO concentrated water recovery and utilization equipment, including filtering and softening system 1, soft water storage unit and reverse osmosis system 2 connected in sequence, filtering and softening system 1 is used for preliminary filtering of tap water to obtain soft water, filtering and softening system 1 can be The quartz sand filter, activated carbon filter, softening and regeneration treatment tank and security filter connected in sequence are used for filtration; the soft water storage unit is used to temporarily store the soft water generated by the filtering and softening system 1, and the reverse osmosis system 2 is used to filter the soft water again , the reverse osmosis system 2 is provided with a reverse osmosis membrane, when the soft water passes through the filtration of the reverse osmosis system 2, the soft water that can pass through the reverse osmosis membrane forms pure water, and ...

Embodiment 2

[0049] The difference between embodiment two and embodiment two is: as figure 2 As shown, in this embodiment, the filter softening system 1 and the reverse osmosis system 2 are simultaneously connected with a cleaning storage tank 17, and the cleaning storage tank 17 is connected with a cleaning and taking pipe 18, and a rinsing delivery pump is installed on the cleaning and taking pipe 18 19. When the filter softening system 1 and the reverse osmosis system 2 perform online cleaning, the water discharged from the leaching contains a small amount of metal ions and other impurities, and the cleanliness is similar to that of tap water, and the leaching water is generated periodically, which is highly controllable. Therefore, use the cleaning storage tank 17 to collect the rinsed water, and use the rinse delivery pump 19 to pump it to the sanitation place as flushing water, so as to realize the recycling of the rinsed water.

Embodiment 3

[0051] The difference between embodiment three and embodiment two is: as image 3 As shown, the soft water output pump is also connected with an independent soft water intake pipe 20, and a soft water intake pump 21 is installed on the soft water intake pipe 20. Since the properties of soft water and RO concentrated water are not completely the same, in the actual use process , it may be necessary to use soft water instead of RO concentrated water. At this time, it is only necessary to use the soft water pump 21 to pump the soft water in the soft water storage tank 4 to the place of use separately.

Abstract

The invention relates to the technical field of water purification, and discloses RO concentrated water recycling equipment and method.The RO concentrated water recycling equipment comprises a filtering and softening system and a reverse osmosis system, a soft water storage unit is connected between the filtering and softening system and the reverse osmosis system, and the reverse osmosis system is connected with an RO concentrated water recycling unit and a pure water utilization unit; the RO concentrated water recovery unit is connected with a use unit; a soft water supplementing pipe is connected between the soft water storage unit and the RO concentrated water recovery unit, and a control mechanism for controlling the soft water supplementing pipe to be connected or disconnected is arranged on the RO concentrated water recovery unit. The RO concentrated water is recycled by arranging the RO concentrated water recycling unit, so that the problems of serious water resource waste and high water purification cost in the water purification process of water purification equipment in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a RO concentrated water recovery and utilization device and method. Background technique [0002] Soft water and pure water integrated treatment equipment can realize the compatible production and supply of soft water and pure water. Compared with traditional pure water treatment equipment and soft water treatment equipment, it can reduce equipment production and operation costs, save equipment placement space, and facilitate equipment maintenance and management. It has been widely used in hospitals, factories and households in recent years because of its advantages in improving the utilization rate of water resources. [0003] In the process of filtering tap water (also known as hard water) by the existing soft water and pure water integrated treatment equipment, the filter softening system is usually used to effectively remove calcium ions, magnesium ions, large part...
