Abstract
The utility model discloses RO (Reverse osmosis) equipment for industrial wastewater treatment, comprising a reverse osmosis device (6), wherein wastewater flows into a water inlet of the reverse osmosis device (6) through a high-pressure pump (3), and a water outlet of the reverse osmosis device (6) is connected to a water recovering tank (8) through a pipeline. The RO equipment for industrial wastewater treatment is characterized in that the water outlet of the reverse osmosis device (6) is connected to a water outlet pipe of the high-pressure pump (3) and a concentrated water tank (4) respectively through pipelines, and the concentrated water tank (4) is also provided with a return pipe (9) connected with the water inlet of the reverse osmosis device (6). With the RO equipment for industrial wastewater treatment, the surface pollution of a reverse osmosis membrane can be effectively reduced, and the utilization rate of water is improved. With the RO equipment for industrial wastewater treatment, the technological processes is simple, the flow rate and the flow velocity of supplied water are increased, and the dirt-flushing capability of water stream at the surface of the membrane is enhanced, thus effectively preventing the influence of precipitation of various impurities on the reverse osmosis membrane and prolonging the service life.
Description
Technical field
The utility model relates to advanced treatment of industrial waste water and recovery technology field, specifically a kind of reverse osmosis equipment that is used for Industrial Wastewater Treatment.
Background technology
Utilize advanced treatment that membrane technique carries out waste water as when last ripe, advanced, water technology efficiently, accepted by people gradually.And with respect to other technologies, reverse osmosis technology has become one of gordian technique in the utilization of wastewater resource technology owing to have remarkable advantages at aspects such as removing solvability such as COD, heavy metal ion, colourity.Though reverse osmosis technology has the high advantage of effluent characteristics, but when intaking to tertiary grade industrial waste water, because condition of water quality is poor, reverse-osmosis membrane element very easily produces pollution, thereby causes that water flux descends, and brings matting frequent, cause the reverse osmosis membrane lost of life, especially for the water quality of some composition complexity, for example when tertiary treatment waste water such as plating, printing and dyeing, percolate during as feed water by reverse osmosis, then above-mentioned shortcoming is more outstanding.Simultaneously, existing reverse osmosis system for improving the system recoveries rate, generally all adopts two-part to handle mounting means when manufacturing and designing, and promptly the dense water of first section reverse osmosis unit, enters second section reverse osmosis unit after treatment again and handles.Adopt the reverse osmosis system of this project organization, because the fluid concentration ratio at second section reverse osmosis unit increases, the dirt that forms membrane element easily is stifled, caused system to be difficult for long-term stable operation, not only increase the replacing frequency of matting frequency and filtration consumptive material thus, but also increased the running cost of advanced treatment.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, provides a kind of and can effectively slow down the reverse osmosis membrane surface contamination, can improve the reverse osmosis equipment of a kind of Industrial Wastewater Treatment of water use efficiency simultaneously.
The technical solution adopted in the utility model is as follows:
A kind of reverse osmosis equipment that is used for Industrial Wastewater Treatment, it includes reverse osmosis unit, waste water enters into the water-in of reverse osmosis unit through high-pressure pump, the water outlet of reverse osmosis unit by pipe connection to return water tank, the water port that it is characterized in that reverse osmosis unit is connected respectively to the rising pipe and the dense pond of above-mentioned high-pressure pump by pipeline, also is provided with the return line that is connected to the reverse osmosis equipment water-in on the dense pond.
Water port on the described reverse osmosis unit is connected to the rising pipe of above-mentioned high-pressure pump and the pipeline in dense pond is provided with flow control valve.
The pipeline that water port on the described reverse osmosis unit is connected to above-mentioned high-pressure pump rising pipe is provided with reflux pump.
The beneficial effects of the utility model have:
Can effectively slow down the pollution on reverse osmosis membrane surface, thereby improve the utilization ratio of water.Not only technical process is simple, increased water supply flow and flow velocity, but also strengthened the scouring capability of film surface current, can effectively prevent the influence that various contamination precipitations bring reverse osmosis membrane dirt, prolong the work-ing life of film, improved the stability of operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model mainly includes high-pressure pump 3, reflux pump 5, reverse osmosis unit 6, adds water tank 8 and dense pond 4, the water outlet of employing high-pressure pump 3 is connected to the water-in of reverse osmosis unit 6, to return water tank 8, the water port of described reverse osmosis unit 6 is connected respectively to the rising pipe and the dense pond 4 of high-pressure pump 3 to the water outlet of reverse osmosis unit 6 by pipeline by pipe connection.And be connected in the water port of reverse osmosis unit 6 on the pipeline in the rising pipe of high-pressure pump 3 and dense pond 4 and be provided with flow control valve 2, be mainly used in the adjusting of the backflow water yield.Simultaneously, also can be as required on the water port of reverse osmosis unit 6 is connected to the rising pipe pipeline of high-pressure pump 3, be provided with reflux pump 5,, improve the utilization ratio of water to add the speed of strong inverse flow.Also be provided with the return line 9 that is connected to reverse osmosis equipment 6 water-ins on the dense pond 4, handle once more so that the water in the dense pond 4 is refluxed.
During the utility model work, have waste water 1 to arrive the high-pressure pump 3 from water inlet pipe earlier, enter into reverse osmosis unit 6 from high-pressure pump 3 through the high-pressure pump rising pipe again, after reverse-osmosis treated, water purification enters into return water tank 8 from water producing pipe 7, is used for recycling.Simultaneously the dense water of part after reverse-osmosis treated is then got back to the dense pond 4 from the water port of reverse osmosis unit 6, and in this process, still some dense water enters into reverse osmosis unit 6 by backflow and carries out secondary treatment.
Other undeclared part that the utility model relates to is same as the prior art.
