Abstract
The utility model relates to a reverse osmosis system for backwashing a filter by using concentrated water. The reverse osmosis system comprises a raw water tank, a first-stage quartz sand filtering device, a first-stage activated carbon filtering device, a first-stage reverse osmosis device, a concentrated water tank, a second-stage quartz sand filtering device and a second-stage activated carbon filtering device which are connected in sequence, wherein an antisludging agent feeding tank is arranged between the first-stage activated carbon filtering device and the first-stage reverse osmosis device; a filter washing pump is arranged between the concentrated water tank and the second-stage quartz sand filtering device. By utilizing the reverse osmosis system, a reverse osmosis concentrated water side is prevented from scaling, the film washing frequency is reduced, the service life of the film is prolonged, and the production efficiency is improved; as the first-stage reverse osmosis concentrated water is temporarily stored up to positively and reversely wash a quartz sand filter and an activated carbon filter, the water resource is sufficiently and effectively utilized.
Description
Technical field
The utility model relates to the technical field of water treating equipment, especially a kind of reverse osmosis system that utilizes dense water backwashing strainer.
Background technology
At known water-treatment technology field, after former water process quartz sand filtration device and the activated charcoal filter pre-treatment, ion wherein is difficult to be removed, after the pre-treatment water outlet enters the first-stage reverse osmosis system again, former water flows to the other end in a side of film from an end, water molecules sees through the film surface, arrive opposite side from former water side, and ion is just stayed an original side, along with former water is progressively concentrated, water molecules is constantly taken away from former water, and the saltiness of staying in the former water progressively increases, and namely former water progressively is concentrated, and finally becomes dense water, discharge from device, dense water is subjected to concentrate the various ionic concns in back and will be multiplied.Ca in the natural water source

3 2-Long-pending generally all less than its equilibrium constant Deng the concentration of the ion that tends to fouling, do not occur so do not have fouling, but after concentrating, therefore the long-pending equilibrium constant that all might substantially exceed of the concentration of various ions can produce serious fouling.In case the film fouling, the flow that produces water will descend, and water quality also can descend, and at this moment just must shut down that timely membrane element is cleaned, and has reduced the efficient of production and the life-span that membrane element uses.
After former water enters the first-stage reverse osmosis system simultaneously, water outlet is divided into two-way, one the tunnel is that pure water supplies with the water spot water or enter next stage to handle, one the tunnel is the dense water after the reverse osmosis membrane processing, and dense water often concentrates several times than the ion content of former water, and the dense water yield is very big, very difficult backflow is handled again, overwhelming majority's pure water equipment system all directly enters trench with it, and water resources is in short supply day by day now, need carry out fully effectively utilizing to water resources.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem that proposes in the above-mentioned background technology, the utility model provides a kind of reverse osmosis system that utilizes dense water backwashing strainer, it can prevent that the reverse osmosis concentrated water side from producing fouling, reduce the number of times that film cleans, increase the life-span of film, enhance productivity; By the dense water interim storage of first-stage reverse osmosis is got up, be used for quartz sand filtration device and activated charcoal filter are just being washed and backwash, water resources has been carried out fully effectively utilizing.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of reverse osmosis system that utilizes dense water backwashing strainer, comprise the raw water box, one-level quartz sand filtration device, one-level active carbon filtering device, first-stage reverse osmosis device, dense water tank, secondary quartz sand filtration device and the secondary active carbon filtering device that connect in turn, be provided with the Scale inhibitors dosing tank between one-level active carbon filtering device and the first-stage reverse osmosis device, be provided with the strainer flushing pump between dense water tank and the secondary quartz sand filtration device.
Further: the Scale inhibitors dosing tank has dosing pump.
The beneficial effects of the utility model: the reverse osmosis system of dense water backwashing strainer that utilizes of the present utility model is by before entering reverse osmosis at pretreated former water, add high efficiency scale inhibitor special, to prevent that the reverse osmosis concentrated water side from producing fouling, can reduce the number of times that film cleans like this, increase the life-span of film, enhance productivity, have practical value.By the dense water interim storage of first-stage reverse osmosis is got up, be used for quartz sand filtration device and activated charcoal filter are just being washed and backwash, water resources has been carried out fully effectively utilizing.
